The sewage outlet into the river is connected to the river at one end and the source of land pollution at the other, which is the last gate for pollutants to enter the river, which is related to the stable improvement of the water ecological environment and is a key battle to deeply fight the battle to defend the clear water. Baoshan District, as a pilot area for the investigation and rectification of the sewage outlet of the Yangtze River in Shanghai, dares to catch up with and surpass the study, has the courage to try first, and has achieved phased work results in investigation and rectification, forming a replicable, generalizable and referenceable model of investigation, measurement, traceability and treatment, and accumulating experience for the city to promote the investigation and rectification of the sewage outlet into the river.
Than have a goal
Lead the city to promote the investigation and rectification of sewage discharges into the river
The Baoshan District Ecological and Environmental Bureau resolutely implements the principle of "jointly grasping great protection and not engaging in large-scale development" in the Yangtze River Economic Belt, and takes the lead in working with the Baoshan District Water Bureau, the District Transportation Commission, the District Agricultural and Rural Committee and other departments and relevant towns to make concerted efforts, summon up full energy, overcome difficulties, and the city takes the lead in piloting the investigation and rectification of the two-kilometer sewage outlet along the Yangtze River, and steadily advances in the whole region.
Up to now, the city has taken the lead in comprehensively completing the investigation of nearly 10,000 discharges in 953 rivers in Baoshan District, simultaneously completing the traceability of more than 2,000 sewage outlets into the river in two kilometers along the Yangtze River and more than 2,000 river discharges in the main section of the municipal and district management and the assessment section, and basically completing the traceability of more than 8,400 sewage outlets in the town and village-level rivers. On this basis, the traceability and problem rectification has been promoted step by step, and 119 discharges along the Yangtze River for two kilometers have been completed, and other discharges are being promoted in "one mouth and one policy", and the progress of work is leading the city.

Multi-level and multi-form learning improves work effectiveness
After the pilot project of investigation and rectification of sewage outlets into the river was launched, the work foundation was very weak, and there was neither technical specification guidelines nor ready-made work experience. The Baoshan Ecological and Environmental Bureau learns while doing and learning while doing, constantly exploring work experience and improving the quality of work.
"Learn now", follow up and master the work guidance issued by the national and Shanghai municipal levels, and quickly connect the requirements of the state and Shanghai.
"Expert science": learn from experts in the ecological environment, water affairs, construction and other industries, familiar with the characteristics of river discharge settings, pipe network construction and maintenance, drainage characteristics of industry, agriculture, municipal administration, construction and other industries.
"Training": Organize multi-level and multi-form training and learning, carry out special training on traceability technology, on-site teaching and training of outlet inspection APP, etc.
"Exchange learning": Establish a WeChat group to communicate and exchange problems encountered between departments in a timely manner, and carry out the exchange of working methods and experience between districts.
Catch up with the initiative
Actively explore the experience of first-come, first-served
Establish a pluralistic linkage mechanism. Formulate a work plan for the investigation and rectification of sewage outlets into the river, link up and link up to form a joint work force; integrate relevant information on sewage outlets into the river, review and trace information, strengthen industry supervision and guidance and rectification; mobilize the initiative of large enterprises such as Baowu Group, Huaneng Power Plant, Shanghai Chengtou, and Shanghai Port Group to independently carry out traceability and rectification of sewage outlets into the river.
Take multiple measures to identify the source of pollution. Make good use of "science and technology + artificial", actively explore the integration system of "air, sky, earth and water", and thoroughly investigate the sewage outlet into the river. Through manual site surveys, people walking with the ship, unmanned ships carrying side sweep sonar, unmanned aerial vehicles near-earth aerial surveys and other means, underwater under the bridge and in hidden areas can be checked.
■■■■■
Comprehensive sampling and monitoring of the sewage outlet into the river and the drainage outlet on dry days, sampling and measuring the rainwater outlet, providing technical support for traceability and rectification, so that all water can be measured.
The use of geographic information analysis technology to lock the scope of on-site traceability investigation, the use of periscopes, pipeline robots, pipeline endoscopes, tracers and ground penetrating radar and other technologies to find out the source of pollution, so as to trace the source one by one.
Explore granular management mechanisms. Relying on the ecological environment data center platform of the whole region, build an information management platform for river discharges, fully integrate information such as various types of river discharges, river bank belt conditions, water system distribution, and sewage pipe networks in the region, establish a database of "one mouth and one file", "one river one file" and "one street and town one file" for all river inlet discharges, and explore the establishment of a long-term and fine management mechanism for sewage outlets with clear responsibilities, reasonable settings and standardized management. Compile the "Technical Guide for the Implementation of Sewage Outlet Investigation, Monitoring and Traceability in Baoshan District" to provide Baoshan experience for the investigation and rectification of sewage outlets into the river in the city.
Super effective
Higher standards to fight the battle of clear water
Through the investigation and rectification of sewage outlets into the river, promote large enterprises such as Baosteel Co., Ltd. and Huaneng Power Plant to actively explore new technologies for water management, actively implement the comprehensive utilization of wastewater and deep treatment of zero discharge; promote a number of small and medium-sized enterprises to benchmark advanced, and realize the upgrading of water pollution control facilities; promote relevant streets and towns to actively explore ecological governance methods for planting industry discharges, pilot water ecological restoration and treatment of rivers in water sources, and improve the level of construction of ecologically clean small watersheds; promote the continuous construction of water environment infrastructure in the whole region, unswervingly adhere to ecological priority, The road to green development. From January to October this year, 15 sections of the "3+15" national and municipal examination sections in Baoshan District reached Class III water quality, which was the best level in history.
