Discharge port supervision and management ｜ Beijing's construction management also tighten the "valve"

In order to guide the implementation of the "Implementation Opinions of the General Office of the State Council on Strengthening the Supervision and Administration of Entry and Entry into the Sea", the Ministry of Ecology and Environment organized a typical practice for localities for reference. Today, the 4th article "Beijing Construction Management and Tightening the" Valve "of the river sewage port". Water is the source of life, the essence of production, and the foundation of ecology. It "nourishes" the beautiful life of the public, and also provides a solid foundation for social and economic development. In recent years, Beijing has adhered to the "three water coordination", which is large to comprehensive protection of the Miyun Reservoir with a total library capacity of 4.375 billion cubic meters. It is as small as the sewage discharge port of about 1 meter in the diameter of the Beijing water system. The appearance of water pollution is in the water, and the root is on the shore. It is the key to promoting the improvement of the quality of the water environment in the river. Since 2019, Beijing has tightened the "valve" of the river sewage outlet through the construction of a regulatory system, comprehensively investigating and rectification, and strengthening long -term mechanisms. In 2020, the city's sewage outlet was completed. Good results. In 2021, the proportion of water quality rivers in Beijing Ⅰ-Ⅲ accounted for 75.2%, an increase of 11.4 percentage points year-on-year; inferior water quality river length decreased by 2.4 percentage points year-on-year to achieve dynamic clearance. Construct a regulatory system "construction management" and re -plan to promote the "new mouth" to clearly "how to build". In terms of new sewage outlets, the first is to improve the approval procedure, combine the actual situation of Beijing and optimize the business environment requirements, the "Notice of the Beijing Ecological and Environment Bureau on the Entry and Elimination Port for Entering the Switting Pass" in November 2020 clarifies the rivers and rivers, Application conditions, materials, methods, processes, approval opinions and other matters for the lake newly built, reconstructed or expand the approval of the sewage outlet approval. The second is to optimize the approval process, build an online ecological environment system online approval platform for the city and district, and "One Netcom Office" to allow the data to run more and let the masses run less legs. "Old mouth" clearly "how to manage". Introduce technical specifications and clarify the existing sewage port "how to treat" and "how to manage". Learn from the work experience of the national pilot cities, and actively explore the Beijing management model. In July 2020, the classification and control technology guide of the sewage discharge port was issued in July 2020 to clarify the classification principles, work ideas and processes, as well as investigating, monitoring, tracing, cleaning up, long -term effects, long -term effects, long -term effects Specific requirements for management and other work to promote the establishment of a "water environment-riverside sewage outlet-pollution source" management system, and provide technical guidance for the refined and standardized management management of Beijing into the river entering the river. Strive for financial support. Apply to arrange the funds for central water pollution prevention projects for the municipal and district levels of dirty -dirt discharge port supervision projects, promote the installation of river sewage outlet monitoring equipment, promote the construction of information management platforms, take the sewage outlet of the river, effectively improve the city , District two -level water ecological environment supervision level. Comprehensively investigate and rectify, sort out, and govern the "three steps" to find out the bottom of the family. In accordance with the principles of "everything to check and check", organize various districts to carry out the source of the sewage discharge port system, master information such as the distribution, quantity, drainage characteristics and direction, and basic conditions of discharge units in various types of sewage outlets. Full caliber ledger. Classified from the three latitude of the type, area, and basin distribution. From the perspective of the type, the urban Yuhong discharge is the main type of the sewage discharge port in Beijing; from the region, most of the sewage discharge ports, the sewage outlets of enterprises and institutions, and the sewage discharge of the sewage of sewage are concentrated in the plain area; From the perspective of the basin, the number of sewage outlets in the North Canal Basin has the largest number of sewage outlets. Shunyi District Xiaozhong Henan French Sewage Treatment Plant retreats from the water outlet, close scenes and traceability conditions. On the basis of establishing a full -caliber ledger in the river drainage port, according to the nature, type, drainage and other conditions of the sewage outlet, combing the list of sewage outlets in the river, and the 216 entry sewage outlets included in the city are included in the cleaning and rectification. Rectification. If the sewage is directly discharged, the sewage access treatment facilities are processed and discharged. If the sewage is discharged through the rainwater oral sewage, the sewage access treatment facility will be set up separately to meet the discharge of the sewage port to keep the rainwater discharge function; To strengthen the operation management or bidding and transformation of the treatment facilities, build wetlands with conditions to be adapted to local conditions to further purify ecological purification; if there is no function, it will be blocked or demolished in time. Rectification in place. The rectification work of the river entry into the river is included in the key tasks of the city's pollution prevention and control battle, and the city -riverside office work information reporting system and the municipal ecological environmental protection inspector are used to promote rectification. Develop the "one -stop" management information platform for the sewage port in Beijing, dynamically update the data information information of the river sewage outlets, improve the relevant information such as the photos before and after the rectification, the water quality test report, etc. On -site research and guidance, clarify the scope of rectification, measures, standards, acceptance and certification materials, etc. The sewage discharge port of Xiaolong River in Daxing District is standardized. At the same time, Beijing explores a long -term supervision and management mechanism of strengthening the entire process, refined, and coordinated by multiple parties. Implement management. Source control, in terms of planning environmental assessment and setting approval, implement the requirements of "three -line and one order", urban overall planning, etc., in accordance with the law, set the access to the new sewage port in accordance with the law, and set the standard setting from the source.

The process supervision, strengthen the management of existing pollution sources, and implement online monitoring of water quality for key sewage discharge units such as sewage treatment facilities in industrial parks, and strengthen the linkage supervision of "sewage discharge units — entering the river sewage outlet". Terminal law enforcement, organizing special law enforcement, basin law enforcement and joint law enforcement, and severely cracking down on illegal acts such as illegal sewage and over -standard discharge. Strengthen refined management. Grid management is connected to the section of the country and municipal assessment of the surface water, and the sewage outlets entering the river are included in the city's 93 surface water control units, and the corresponding relationship between the "sewage outlets -water environment" is established. Quick response, use the newly -built small water quality monitoring stations and regulatory platforms in each district. When the water quality of the sewage outlet is abnormal, it will be warned in real time. Managers quickly arrive at the scene inspection and disposal. Dynamic updates, combined with the progress of daily management, law enforcement inspections, cleaning and rectification, etc., update the river drainage accounts on a quarterly, and timely grasp the changes in the sewage outlets in a timely manner. The water quality and water volume of the sewage outlet of Zhoukou Entou River in Fangshan District Entry Monitoring Station Fengtai District entering the river sewage outlet supervision platform fingerprint map and point traceability alarm promotion system governance. By issuing measures such as sewage discharge permits and supervision and law enforcement, the requirements for maintenance, self -monitoring, and discharge of standards for the main body of the sewage outlet are clarified. Through the river length system and municipal environmental protection inspection mechanism, the local government's investigation, rectification, and refined management are strengthened. Through the planning approval, annual task formulation, inspection and evaluation and scheduling, etc., the implementation of various tasks is coordinated. The construction and operation management of the sewage treatment plant station, the sewage discharge of rainwater pipelines, and the pollution treatment during the flood period, the pollution treatment of agricultural and rural facial sources, and the improvement of small and micro -water body treatment, and establish a combination of point source governance and facial source governance, engineering measures and management measures Combined with the system governance model combined with the local government and functional departments. Yichong water, unaware of it, lose difficulty. With water, the city has the beauty of agility, and the development of the city has support. In the next step, Beijing will be pushed into the long -term supervision of the sewage mouth into the river, strengthen water and land coordination, systematic governance, adhere to the "three water coordination", and let people with "water clear shore green and fish shallow bottom" are resident. Essence The results of the new Fenghe comprehensive management of Daxing District have achieved remarkable manuscripts | Editor of the Ministry of Ecological Environment of the Ministry of Ecology and Environment | Song Xiang review | Qin Chao
