Currently, how many sewage outlets are there around the Bohai Sea, where are they being discharged, who is discharging, what is being discharged, and how much is being discharged?
In order to implement the Party Central Committee and the State Council’s recommendations on combating pollution The deployment of prevention and control measures has solidly promoted the investigation and rectification of sewage outlets into the sea in the Bohai Sea region. Based on the experimental investigation in Heiyanzi Town, Tangshan in January this year, the Ministry of Ecology and Environment launched Tangshan, Hebei, Tianjin (Binhai New Area) on June 24 ), Dalian, Liaoning, Yantai, Shandong and other four cities, including on-site inspections of sewage outlets into the sea.
According to the work arrangement, the on-site work lasted for one week, and a drag-net inspection method was adopted to inspect all sewage outlets along the coast to achieve the goal of investigating everything that is said and everything that should be investigated. Taking into account factors such as the length of the coastline and the workload of the four cities, it is planned to arrange 60 on-site teams from Tangshan, 40 teams from Tianjin (Binhai New Area), 100 teams from Dalian, and 60 teams from Yantai, for a total of 260 teams, with a total of 780 people participating in the on-site inspection work. According to statistics, the coastline length of the four places is about 1,700 kilometers, which involves coastal towns, ports, docks, industry, fisheries and natural coastlines.
The main goal of the investigation is to comprehensively investigate the sewage outlets into the Bohai Sea, and to identify all "openings" that discharge sewage into the Bohai Sea. The specific targets of investigation are various water-related outlets that directly or indirectly discharge pollutants into the Bohai Sea, including water-related outlets that directly discharge pollutants through pipelines, culverts, ditches, etc., or indirectly discharge pollutants into the Bohai Sea through rivers, streams, etc. wading outlet.
Use water quality formaldehyde detector, sewage analyzer, sewage ammonia nitrogen rapid detection instrument, total phosphorus integrated analyzer, and nitrite meter , hydrogen sulfide online detector, nickel ion total nickel detector, E. coli monitor, fluoride detector, water quality heavy metal detector and other advanced instruments and equipment to detect and analyze the sewage from the sewage outlet.
In accordance with the "Special Action Plan for Inspection and Rectification of Sewage Outlets into the Sea in the Bohai Sea Region", the "three-level inspection" model is adopted, that is, satellite remote sensing and drone aerial survey, on-site inspection by personnel, and inspection of difficult points. Leak-repairing methods will be used to comprehensively identify all “openings” for sewage discharge into the Bohai Sea. At present, the four cities of Tangshan, Tianjin (Binhai New Area), Dalian, and Yantai have completed drone aerial survey and image interpretation work, and have screened the suspected sewage outlet information discovered by the aerial survey one by one and entered it into the mobile APP system. On this basis, the Ministry of Ecology and Environment directly organized personnel to carry out on-site inspections in accordance with the "one pole to the end" approach.
After the on-site inspection begins, the inspectors will closely follow the guidance of the mobile APP system.Keep an eye on “three under, five under, and two under”. “Three under” refers to the blind areas of drone aerial surveys such as under bridges, under water, under forests, etc., and there may be sensitive areas with hidden drainage outlets; “five under” refers to the seaside and the riverside that enters the sea. , ports, terminals, industrial clusters, population clusters and other key areas where sewage outlets are concentrated; "two" means that on-site inspections must complete two tasks: suspected points provided by drones must be investigated, and points that have not been discovered by drones Don't miss the bit either. "Using both high technology and hard work", we ensured that all sewage outlets into the sea "should be fully investigated" through three-level inspections.
During the on-site investigation, a temporary party group will be established to fully implement the requirements for strict party governance and disciplinary style, insist on not disturbing, not replacing, and not interfering with the normal work of the local area, mainly to help The local search for sewage outlets into the sea will be handed over to the local government for resolution. The on-site food, accommodation and transportation expenses of all investigators will be uniformly settled by the Ministry of Ecology and Environment in accordance with relevant regulations.
According to the plan, before the end of this year, the Ministry of Ecology and Environment will also complete on-site inspections in nine other cities around the Bohai Sea (three provinces and one city) to fully understand the situation of the sewage outlets entering the Bohai Sea, and provide guidance for the next step. Lay the foundation for monitoring, traceability and governance.
Background information: Bohai Sea sewage outlet inspection and rectification actions
The Bohai Sea is a semi-enclosed inland sea in my country, with unique natural ecology, significant geographical advantages, and strategic With a prominent position, it is the strategic support and key support for the economic and social development of the Bohai Rim region. In recent years, the quality of the Bohai Sea has improved, but the total discharge of land-based pollutants remains high, the environmental quality of key bays has not fundamentally improved, and the overall ecological environment situation remains severe.
Currently, how many sewage outlets are there in the Bohai Rim, where are they being discharged, who is discharging, what is being discharged, and how much is being discharged? In 2019, the Ministry of Ecology and Environment, together with the "three provinces" in the Bohai Rim, The government of "One City" has made every effort to promote the special action to investigate and rectify the sewage outlets into the Bohai Sea. The main goal is to comprehensively identify and effectively control the sewage outlets into the Bohai Sea, and to identify all "openings" that discharge sewage into the Bohai Sea.
In order to implement the decisions and arrangements of the Party Central Committee and the State Council on fighting a tough battle against pollution, on January 11, 2019, the Ministry of Ecology and Environment held an "Inspection and Regulation of Sewage Outlets into the Sea in the Bohai Sea Region" in Tangshan City "Special Action Launch Meeting" fired the "starting gun" for the investigation and rectification of sewage outlets into the sea. The work tasks of special operations can be summarized as “inspection, testing, tracing", control" four key tasks. The first is to find out the bottom number of sewage outlets into the sea. The second is to carry out monitoring of sewage outlets into the sea. The third is to trace the source of sewage from sewage outlets into the sea and clarify responsibilities. The fourth is to rectify the problem of sewage outlets into the sea.

The focus of the work in 2019 is to do a good job in the investigation and monitoring of sewage outlets, which is mainly divided into two stages: before the end of June 2019, complete the thorough investigation of some cities and carry out preliminary monitoring at the same time. Other cities will use satellite Self-examination will be carried out through remote sensing, drone aerial survey and other means. By the end of 2019, the inspection and monitoring of all sewage outlets in all cities around the Bohai Sea will be completed. At the same time, localities are encouraged to take the initiative to carry out traceability and rectification tasks according to local conditions, and form a right-based approach. A supervision system for sewage outlets into the sea and rivers with clear responsibilities, adequate monitoring and standardized management will lay the foundation for improving the ecological environment quality of the Bohai Sea and the Yangtze River.
