Use "Xi'an Blue" to depict an ecological picture
Since the launch of the air pollution control special action for more than seven months, the comprehensive air quality index of Xi'an has improved by 15.1% year-on-year to 3.66 in the second quarter of this year, and 3.30 in the third quarter of this year, an improvement of 8.8% year-on-year. As of November 27, the number of good days in the year increased by 31 days year-on-year. From the perspective of changes in various indicators, air quality has improved significantly, and policy measures are effective and effective.
The blue sky and white clouds are often guests, and the green waters and green mountains come into the painting.
Walking through the ancient capital of Xi'an, you will find that the sky has become bluer, the water has become clearer, the Qinling Mountains have become greener, and the eyes are full of thriving ecological beauty. The painting of this ecological beauty is due to the fact that the Xi'an Municipal Party Committee and Municipal Government of Shaanxi Province adhere to the core of improving the quality of the ecological environment, and always take winning the battle of pollution prevention and control as the top priority of ecological civilization construction.
This year is the first year for the full implementation of the spirit of the 20th National Congress of the Communist Party of China, the key year for the implementation of the "14th Five-Year Plan", and the breakthrough year for promoting the practice of Chinese-style modernization in Xi'an. Create a high-quality life and strive to build a beautiful Xi'an where man and nature coexist in harmony.
Clear sky, gentle breeze, the people's livelihood, the people's hope. Xi'an takes the blue sky defense battle as the top priority, highlights precise pollution control, scientific pollution control, and pollution control in accordance with the law, comprehensively carries out special actions for air pollution control, and makes every effort to consolidate and improve air quality, so as to create a "good temperament" for blue sky and white clouds.
Hit a "combination punch" to set off an upsurge of air pollution control
On April 4, the Xi'an Municipal Party Committee and the Municipal Government held a mobilization meeting for the city's air pollution control special action, set up a leading group for the special action on air pollution control headed by the secretary of the municipal party committee and the mayor, and formulated the "Xi'an Air Pollution Control Special Action "1+3+22" Combination Work Plan (2023-2027), focusing on promoting the "four major structural adjustments" of energy consumption, urban heating, industrial development, and transportation, and implementing scattered coal governance, agglomeration and upgrading, vehicle optimization, dust control, The environmental protection industry cultivates the "five major governance projects", carries out the "four special actions" of in-depth treatment of industrial enterprises, heavy pollution weather response, summer ozone response, and comprehensive non-point source treatment, and takes 60 key tasks and 95 specific task lists in 2023 as the starting point, and plays a "combination punch" of Xi'an's air pollution control battle, and comprehensively sets off an upsurge of air pollution control.
The city has carried out special actions for air pollution control, and the main leaders of the municipal party committee and the municipal government have repeatedly investigated the development of air pollution control, held more than 20 meetings at the municipal level, and introduced relevant policies and measures in terms of loose coal governance, diesel vehicle elimination, new energy vehicle promotion, truck bypass restrictions, etc., and repeatedly demonstrated and analyzed long-distance heating projects, and systematically promoted key tasks. The Standing Committee of the Municipal Party Committee and the Deputy Mayor have been established, and the leading departments at the municipal level have actively strengthened supervision, grasped the response, and adjusted the structure, and the districts, counties and development zones have paid close attention to the implementation of responsibilities, strengthened grid management, and focused on biomass combustion sources, coal-fired sources, mobile sources, dust sources, Precise policies in key areas such as industrial sources, focusing on the focus on responding to ozone during the summer prevention period, focusing on controlling heavily polluted weather during the winter prevention period, strictly managing key areas, strengthening law enforcement accountability, strengthening scientific and technological support, coordinating and promoting the synergy of pollution reduction and carbon reduction, accelerating the formation of a green development mode, and striving to solve the structural and root causes of the improvement of the city's ambient air quality, greatly reducing pollutant emissions from the source, and promoting the continuous improvement of ambient air quality.
Xi'an holds a monthly special action scheduling meeting for air pollution control to analyze the progress in a timely manner and arrange the deployment of the next stage of work. In accordance with the principle of "unified command, rapid response, efficient operation, and closed-loop management", the Xi'an Municipal Atmospheric Special Office strictly implements the "75311" working mechanism (i.e., 7-day accurate prediction and forecasting, 5-day analysis and evaluation, 3-day control and scheduling, 1-day full-time duty, and 1 supervision and inspection team during the response period) to carry out air quality analysis and forecasting every day and carry out air quality analysis and judgment and monitoring and consultation every week for heavy pollution weather in autumn and winter, ozone pollution response in summer and major activities. We will further improve the linkage early warning mechanism, release early warning information in a timely manner, and simultaneously initiate emergency response, so as to continuously improve the level of precise governance.
Promote the adjustment of the "four major structures" in an orderly manner and accelerate the green and low-carbon transformation
Since the beginning of this year, 112 key industrial enterprises have been inspected and assessed for the "dual control" of energy consumption, and special energy-saving supervision has been implemented for the newly included 23 key energy-using units at the municipal level. In terms of the adjustment of the urban heating structure, no new coal-fired central heating stations will be built, the city's geothermal energy heating area will exceed 10 million square meters, and the heating operation mode will be actively optimized, and the construction of the city's heating "one network" will be promoted. In terms of industrial development structure adjustment, we guided the completion of the VOCs "Green Island" project in Xixian New Area, which is the first "demonstration point" project for ozone pollution prevention and control in the province, completed the relocation of 10 key gas-related enterprises and the shutdown of 21 brick kiln enterprises, and completed the shutdown of the coal-related production line of the high-emission gas furnace enterprises of China Glass New Technology Co., Ltd. ahead of schedule, so as to achieve zero non-electric coal. In terms of transportation structure adjustment, the "Notice of the People's Government of Xi'an Municipality on the Management of Cross-border Trucks" and the "Notice of the People's Government of Xi'an Municipality on Strengthening the Management of Diesel Truck Traffic" have been formulated and issued, which will be implemented from December 1, 2023, which is conducive to improving the capacity of the Ring Expressway and easing the urban traffic flow , take multiple measures to promote the prevention and control of pollution from diesel trucks. Up to now, the proportion of "road-to-rail" railway transportation in the city's five power plants has exceeded 80%, of which the proportion of clean transportation in Datang Baqiao Thermal Power Plant has reached 100%, 2,144 diesel trucks of China III and below have been eliminated, exceeding the annual task, and 1,164 commercial concrete vehicles have been replaced by China VI or new energy, and 2,720 muck vehicles have been replaced. To speed up the promotion and use of new energy vehicles, the number of new energy vehicles in the city has exceeded 360,000, and the purchase of 29 new energy sanitation vehicles has been completed this year, and 8,195 new energy logistics and distribution vehicles have been updated.
"Loosen" for high-quality construction sites, and differentiate the control of construction dust
Xi'an implements differentiated management of construction dust control, and divides construction sites into Class A (dust control standard construction sites), Class B (dust control standard construction sites), and Class C (dust control and strict management sites). The purpose of differentiated management is to evaluate the construction sites that have done well in dust control, reduce the number of on-site inspections of Class A and B construction sites, and "loosen" the high-quality construction sites. Through the implementation of differentiated management, we actively guide enterprises to change from passive dust control to active dust control.
At the same time, on the basis of "6 percent, 7 in place" and technical guidelines, 40 specific measures have been formulated from 8 aspects, including construction management, enclosure setting, hardening and cleaning, vehicle washing, covering and covering, wet operation, main construction, earthwork backfill and greening construction, to refine the requirements and establish a unified standard for construction dust pollution control. In accordance with the principle of "whoever has jurisdiction over the jurisdiction, who is responsible", all districts, counties and development zones should improve the supervision ledger of their jurisdictions, put an end to the blind spots of supervision, and implement the responsibility of territorial supervision; the enterprises participating in construction projects should adhere to the principle of "whoever pollutes shall be treated" and strictly implement the main responsibility; and take joint action to create a new situation of dust control of "1,000 construction sites and a set of standards".
At present, there are 1,599 dust supervision construction projects in the field of housing and construction in Xi'an, and 1,502 project sites connected to the dust online monitoring system have been connected. Focusing on the early warning of dust exceeding the standard, taking the attendance rate of key personnel as the starting point, making full use of the two information means of the dust online monitoring system and the real-name management system, and effectively combining "online inspection", "remote monitoring" and "on-site inspection" to further improve the efficiency of supervision.
Pay close attention to the source of treatment and build a "protective net" for air pollution
In the scorching summer, in the face of ozone pollution soaring with the temperature, Xi'an ecological and environmental protection people braved the scorching heat to insist on the front line. "Just like a doctor treating a disease, we carry out targeted monitoring to detect and solve problems early. The monitoring personnel of the Weiyang Branch of the Xi'an Ecological Environment Bureau used a multi-functional gas detector to monitor the asphalt flue gas and particulate matter emissions of the two asphalt mixing enterprises in production. In order to accurately "take the pulse" of ozone pollution, the monitoring personnel who were soaked in sweat and work clothes carried intelligent comprehensive sampling, detection and other equipment, and entered the factory and climbed the tower under the high temperature of nearly 40 degrees, and followed the discharge pipeline to find out whether there was any leakage, and did not let go of any pollution production link.
Xi'an continues to increase the intensity and frequency of supervision and monitoring of volatile gas emission units such as industrial enterprises, automobile repair service industries, and gas stations, dynamically grasp the current emission status of gas-related enterprises, and provide timely and accurate support for supervision. During the summer prevention period, ozone grading control was implemented, highlighting the control of volatile organic compounds during the day and the reduction of nitrogen oxides at night, and more than 700 auto repair enterprises and more than 500 gas stations were implemented to stagger peak and staggered production according to different control levels.
"We must not burn in the open air, which not only pollutes the air, but also easily forms fire hazards, and it is an illegal act. In the field, the municipal first-level grid staff of the Xi'an Smart Environmental Protection Comprehensive Command Center continued to use the "inspection + publicity" work mode, while handing the publicity materials to the villagers, while publicizing and explaining the hazards of straw burning and the comprehensive utilization policy of straw to the villagers, so as to change the consciousness of the masses from the source. At the same time, the Xi'an environmental protection fireworks monitoring system realizes 24-hour 360-degree all-round monitoring of agriculture-related areas and counties through 467 points. The establishment and operation of this technical prevention system can accurately detect air pollution caused by fireworks and straw burning, and effectively prevent it from "burning".
More than 1,200 grid members of the city's three-level grid focused on outstanding problems in the prevention and control of air pollution such as dust pollution, biomass combustion, and volatile organic compound emissions in industries such as automobile repair, catering, and gas stations. According to statistics, since the beginning of this year, the city's grid staff has inspected and inspected more than 970,000 pollution source units (times), and supervised the completion of rectification on the spot for the problems that can be rectified. Reduce pollution from the source and build a "protective net" for air pollution.
Paid recycling of loose coal, and multiple measures to ensure that the masses are clean and warm for the winter
In view of the scattered coal combustion source, Gaoling District carried out the household investigation of loose coal treatment in accordance with the principle of "voluntary and market-oriented operation", and paid for the recovery of the loose coal discharged. As of mid-October, the investigation work has been completed, and the total amount of loose coal discharged is 202.7 tons. Gaoling District also issued a proposal to the public to ban the burning of loose coal through online means such as WeChat groups and financial media, publicizing the latest "coal to clean" policy and the hazards and safety hazards caused by loose coal combustion. Through various forms, guide the masses to actively participate in the work of air pollution control, and jointly create a beautiful and livable living environment.
In accordance with the "Work Plan for the Clean-up and Remediation of Loose Coal in the Combustion Ban Zone of Xi'an", all districts and counties in the city have carried out a survey in the ban zone to effectively find out the bottom number of the stock of loose coal, carry out paid recovery of loose coal, and ensure the dynamic clearance of loose coal in key areas. At the same time, the implementation of subsidy funds to effectively reduce the cost of clean heating. The "Xi'an Loose Coal Governance Clean Energy Substitution (Coal to Clean) Financial Subsidy Program" further improves and refines the detailed rules for the issuance of subsidy funds, and subsidizes coal to clean users in rural areas in accordance with the operating subsidy standard of not less than 600 yuan per household, and urges power grid enterprises to strictly implement preferential policies on electricity prices to ensure that the masses are clean and warm in winter.
Pay close attention to all kinds of pollution control, and do a good job in autumn and winter air pollution control
At the beginning of September, Xi'an launched the consolidation and improvement of air pollution control, and actively planned to carry out air pollution control in autumn and winter in advance. The "Xi'an 2023-2024 Autumn and Winter Air Pollution Comprehensive Control Action Plan" has been formulated and issued, focusing on 32 key tasks in coal reduction, dust suppression, vehicle control, and burning ban, promoting the "summer disease and winter treatment" action, revising and improving the emergency plan, strengthening regional joint prevention and control, effectively responding to heavily polluted weather, increasing supervision and law enforcement and assistance, strengthening supervision and assessment, effectively compacting work responsibilities, and paying close attention to all kinds of pollution control. At the same time, we will continue to do a good job in publicity and guidance, and publicize ecological and environmental protection laws and regulations, the "Shaanxi Citizens' Blue Sky Convention" and control policies such as loose coal burning, straw burning, fireworks and firecrackers, and vehicle bypasses through outdoor electronic screens, subway and bus mobile TVs, mobile phone text messages, Douyin, public accounts, etc., and guide the masses to actively participate in and support air pollution control.
During the winter prevention period, affected by the small environmental capacity and poor diffusion conditions, coupled with heating pollution, open burning pollution, and scattered coal burning pollution, once regional heavy pollution weather occurs, it may cause a long-term pollution process and seriously affect air quality. Xi'an adheres to the same goals, no reduction in standards, and no reduction in intensity, focuses on key areas, key areas, and key periods, and coordinates the work of enterprise emission reduction, scattered coal management, and the ban on burning and burning, so as to minimize heavy pollution weather. Actively play the role of the Guanzhong urban agglomeration in the joint prevention and control of air pollution control convening city, and Xianyang City, Weinan City and Yangling Demonstration Zone to establish a joint law enforcement mechanism for air pollution control in autumn and winter, carry out joint special supervision and inspection and cross-law enforcement inspection actions, coordinate and linkage, form a joint force, and promote the winter air pollution control work with more pragmatic measures and more positive actions to achieve remarkable results.

Up and down linkage, horizontal union
Xi'an's "2023 Sword Pollution Fighting" special action has begun to show results
In order to fight the battle to defend the blue sky, Xi'an City, Shaanxi Province, has adopted the form of "upper and lower linkage and horizontal cooperation", giving full play to the functional role of relevant departments in protecting the ecological environment and cracking down on illegal crimes, forming a joint work force, focusing on key regions, key areas, key enterprises and key issues, and orderly promoting the "2023 Sword Pollution Control" special action (hereinafter referred to as the special action) to help continuously improve the quality of the atmospheric environment.
Since the launch of the special operation, the Xi'an Municipal Bureau of Ecology and Environment, together with the Municipal Public Security Bureau, the Municipal Procuratorate, the Municipal Market Supervision Bureau and the Xi'an Railway Transport Branch of the Shaanxi Provincial Procuratorate, has established a special operation headquarters to implement unified command and joint operations, and strengthen departmental coordination and cooperation. Through the three stages of clue mapping, joint inspection and supervision and inspection, the special action will be deepened, focusing on key areas and areas, adhering to the principle of "investigating together at the beginning and tail, and fighting together at the upstream, middle and downstream", tracing the source, digging deep along the line, and severely cracking down on environmental violations and crimes.
In the special action, Xi'an insisted on achieving the "four strengthenings". Strengthen the clue discovery mechanism, and extend the tentacles to the grassroots level by collecting complaints from the masses and clues on problems in grid supervision. Strengthen mechanisms for assisting in handling cases, and rely on industry experts and professional bodies to assist in verification of technically complex or highly specialized issues, to ensure that the characterization is accurate. Strengthen scientific and technological support mechanisms, use data analysis and comparison to screen abnormal situations, use video surveillance and other means to find traces of fraud, and equip front-line law enforcement personnel with necessary monitoring equipment to improve law enforcement efficiency. Strengthen the law enforcement supervision mechanism, strictly implement measures such as "double investigation in one case" and "coordination of discipline and law", review the cases of repeated investigation and repeat offenses of the same enterprise, inadequate punishment or exceeding discretion, and put an end to the occurrence of problems such as "failure to investigate the case" and "substitution of punishment with fines".
The Special Operations Command has set up five supervision and inspection teams to carry out special investigation and handling of key cases. Continue to deepen the connection between administrative law enforcement and criminal justice for ecological and environmental protection, and promote the realization of "all links, all elements, and all chains" to combat environmental pollution crimes. As of the end of October this year, the city has inspected a total of 9,445 enterprises (times), investigated and dealt with 264 cases of illegal discharge of pollutants from gas-related pollution sources, and announced 3 typical cases.
In the next step, Xi'an will follow the principle of "full coverage, zero tolerance, strict law enforcement, and practical results", adhere to the "crack down on environmental violations and crimes that are discovered", strengthen the comprehensive use of daily continuous punishment, sealing and seizure, limiting production and suspension, and transferring them to administrative detention.

Highlights of Xi'an's gas control
●"Straw" does its best to protect the "sky blue"
Since the beginning of autumn, Gaoling District, Xi'an City, Shaanxi Province, has taken the source of biomass combustion as the focus of air pollution prevention and control, adhered to the "combination of dredging and blocking, and promoted prohibition with use", focusing on the ban on straw burning, centralized disposal, and straw leaving the field, etc., and continued to make the "blue sky online".
Passing by the fields and the front and back of the houses in Gaoling District, the masses were pleasantly surprised to find that the straws, dead branches and weeds that had been piled up in front of the houses and behind the houses and on both sides of the rural roads had disappeared, and the environment had become clean and tidy.
The sub-district offices of Gaoling District used 20 days to carry out the removal and collection of straw, dead branches, vines, weeds, etc., combined with the actual situation of each village in the jurisdiction, successively set up 35 centralized straw stacking points, and transported the straw collected by the village group to Xi'an Jingwei Kangheng Environmental Engineering Company (Gaoling Waste Incineration Plant) for centralized disposal, with a total of 1,280 tons of straw removed.
In the fields, staff from the Gaoling Branch of the Xi'an Municipal Bureau of Ecology and Environment can often be seen, explaining to villagers the dangers of straw burning and the significance of the ban on burning. "By going into the fields, into the farmers' homes, and the mobile publicity of the propaganda vehicle, the masses can understand the straw burning ban and the comprehensive utilization of straw policy. ”
Gaoling District also aims at low-carbon environmental protection and agricultural efficiency, diversifies the use of straw, focuses on straw fertilizer, base material, feed and energy, and creates a low-cost and high-efficiency green agricultural industrial chain. Zhangbu Street has realized a complete set of planting and breeding cycle system of "planting grain in the field, forming grain stalks, feeding cattle with stalks, producing manure from cattle, turning manure into fertilizer, and returning fertilizer to the field".
●Comprehensively promote the "1234" mechanism and weave a dense industrial enterprise supervision network
Lintong District, Xi'an City, Shaanxi Province, innovated and comprehensively promoted the "1234" mechanism, and promoted the improvement of the quality of the ecological environment by consolidating the four-level supervision of industrial enterprises.
The "1234" mechanism specifically includes, "1" is a list of law enforcement, that is, through the full coverage of the investigation and mapping of the establishment of the Lintong District law enforcement and supervision work account, the basic information of the district's industrial enterprises, the contact information of the four-level supervisors, etc., to ensure that the supervision base is clear, the situation is clear; "2" is a two-pronged approach, the implementation of two-sided management of the government and enterprises, with enterprise self-inspection as the mainstay, supplemented by departmental assistance and supervision, to eliminate environmental violations from the source. "3" is a three-level training system, which trains enterprises, street office cadres and full-time grid personnel on ecological and environmental laws and regulations, and improves the professional ability of law enforcement personnel and the level of enterprise environmental management; "4" is a four-level supervision, establishing a four-level supervision system of industry leadership, ecological environment law enforcement, street office contracting, and full-time grid supervision, and weaving a dense law enforcement and supervision network for industrial enterprises.
In Xi'an Yili Taipuke Beverage Co., Ltd., more than 100 people from district-level regulatory departments, street offices, cadres in the park, and representatives of 30 enterprises in the jurisdiction observed the scene. Hu Xuegang, captain of the Law Enforcement Brigade of the Lintong Branch of the Xi'an Ecological Environment Bureau, gave a detailed explanation of the "1234" mechanism. All departments should strengthen linkage and cohesion, help enterprises coordinate and solve problems, and improve the management level of ecological and environmental protection of enterprises.
