Digital, low-carbon, recycling-what other surprises can the Lanqing 3rd Road Waste Transfer Station bring?

The garbage transfer station on Lanqing 3rd Road in Longhua District, Shenzhen, gave people the impression that it was dirty and smelly a few months ago. Ms. Tang, who works nearby, said that when she passed by the garbage transfer station at work, she pinched her nose and walked, but since the garbage transfer station placed the container of "Lushui No. 1", the smell was indeed gone, and later she learned that it was sewage treatment equipment.

The Lanqing 3rd Road garbage transfer station collects and transports 4 boxes of compressed garbage per day, and the actual transfer volume can reach more than 40 tons a day, and the waste liquid and flushing water generated by garbage compression are 7 tons per day. On rainy days, more than 10 tonnes of sewage are generated. Before the renovation, the sewage was directly discharged into the municipal pipe network after tertiary sedimentation treatment, and its drainage did not meet the standard of pipe acceptance, which not only did not meet the requirements of the code policy, but also had the risk of blocking the sewage pipeline, not only that, but part of the flushed sewage would also flow along the ground to the rainwater nullah on the east side of the garbage station, and be discharged into the natural water body, polluting the surrounding environment. And because there is no self-repurposing system, these production flushing operations will use a large amount of tap water, which does not meet the requirements of energy saving, carbon reduction and green development.

In June this year, the National Development and Reform Commission and other departments issued the "Notice on Making Up for the Shortcomings of Public Health and Environmental Facilities and Carrying out Urban and Rural Environmental Sanitation Cleanup and Remediation", emphasizing the importance of sewage treatment and resource utilization. The person in charge of the Municipal Management Service Center of the Guanhu Sub-district Office of Longhua District closely followed the national policy, and the Lanqing Third Road Garbage Transfer Station actively learned from the advanced cases that have been transformed in Longhua District, introduced the advanced technology of Shenzhen Yao Xinmiao Environmental Technology Co., Ltd., and introduced the integrated leachate treatment equipment of the garbage transfer station according to the site land and size, and started a new upgrade with the theme of "digital, carbon reduction and recycling" in July this year.

Chen Bo, general manager of Shenzhen Branch of Shenzhen Yuhetian Smart City Operation Group Co., Ltd., said: Guanhu Street City Steward Project is the first project of Yuhetian Group in Shenzhen, the introduction of waste water resource technology of garbage transfer station, and also a new attempt of Yuhetian Group in the field of urban housekeeper, the city housekeeper 1.0 era is the key treatment of solid waste and gas waste, and the 2.0 era will increase the measures for liquid waste management.

digit

Yao Xinmiao Environment has applied artificial intelligence technology to the field of sewage treatment, and the renovated Lanqing 3rd Road Garbage Transfer Station has a control center that can easily monitor and manage the entire sewage treatment system. With the help of AI algorithms, it can quickly calculate the dosage and aeration required for the water treatment process, and feed back to the control system to accurately control the operation of the equipment. The equipment runs automatically around the clock, without manual supervision, greatly reducing labor costs and operating costs. In addition, the presence of a control center significantly reduces the workload and difficulty of sanitation workers, and with the assistance of artificial intelligence, sanitation workers only need to regularly add chemicals and replace bags filled with sludge according to a pre-set amount of chemicals.

"In the past, many details needed to be grasped by manpower, which was not only cumbersome but also prone to errors, but now the equipment can directly tell us how to do it, which is simpler than before, and the environment is better than before, and the mood is also good at work." A staff member at the garbage transfer station said.

Carbon reduction

According to the site and size of the Lanqing 3rd Road garbage transfer station, without changing the overall structure of the original space, the renovation project will place the integrated treatment equipment on the green space on the south side of the garbage compression workshop, the equipment occupies a small area, the installation is also very convenient, and its daily sewage treatment capacity can reach 10 cubic meters.

The renovation project has improved the sewage collection facilities in the station, so that the sewage in the whole area can be effectively treated, which not only reduces the source of odor, cures the pollution of the surrounding environment, but also effectively reduces the maintenance cost of the sewage pipe network.

On the other hand, artificial intelligence can also minimize consumption by accurately calculating energy consumption and drug consumption, thereby reducing existing carbon emissions.

Recycling

Water resources are an important resource for the development of a city, and the development of water-saving industries is an inevitable requirement for the high-quality development of cities. There are 123 waste transfer stations in Longhua District, Shenzhen, and it is estimated that the waste transfer stations in the district consume about 170,000 tons of water per year, which is mainly used to flush toilets and clean the transfer station site. In fact, it is sufficient to flush toilets and wash transfer station sites with grey water, but most waste transfer stations are not equipped with a self-return water system, so they still use tap water, which is undoubtedly a waste of water resources.

After the transformation and upgrading, the water treated by the equipment of Lanqing 3rd Road Garbage Transfer Station can stably reach the indicators of toilet flushing and vehicle flushing water in the "Urban Sewage Recycling - Urban Miscellaneous Water Quality Quality" (GB/T 18920-2020), which can be used synchronously for station flushing and municipal road flushing, which greatly saves the amount of tap water used, and can save more than 3000m³ of tap water per year.
