Grasp the "last hurdle" of emissions testing to take a good environmental protection "important hurdle"

In March last year, the State Council issued the "Implementation Opinions on Strengthening Supervision and Management of Outfalls into Rivers and Seas" (hereinafter referred to as "Opinions"), emphasizing that outfalls into rivers and seas are important nodes in the ecological protection of watersheds and seas, clarifying the reform direction of strengthening and regulating supervision and management of outfalls, proposing the integration of water and land, determining the shore with water, clarifying responsibilities, strict supervision, unified requirements, differential management, and The Ministry of Ecology and Environment (MOE) and the Ministry of Environmental Protection (MEP) have set up a series of targets for the years 2023 and 2025.

　　At the end of the same year, the Ministry of Ecology and Environment and the Ministry of Water Resources jointly issued the Notice on the Implementation of the Opinions of the General Office of the State Council on Strengthening the Supervision and Management of River and Sea Outfalls (hereinafter referred to as the Notice), further refining the tasks mentioned in the Opinions and specifying the time points and specific requirements. It is easy to see that the outfall into the river and the sea has a very special significance for environmental protection, especially for the environmental protection of water bodies, and to ensure that the detection of sewage work to improve the quality of the water ecological environment, protection and construction of beautiful rivers and lakes, beautiful bay has an important and positive role.

　　In fact, the issuance of "Opinions" and "Notice" has also reaped good results under the active implementation of work around the world. According to the Ministry of Ecology and Environment announced the national surface water environmental quality in 2022, the national water quality of good (Ⅰ-Ⅲ) section ratio reached 87.9%, an increase of 3%, including the seven major river basins and the northwest rivers, southwest rivers and Zhejiang and Fujian piece of rivers, the proportion of good water quality (Ⅰ-Ⅲ) section reached 90.2% The water quality in Zhejiang and Fujian rivers, the Yangtze River basin, the southwest rivers, the northwest rivers and the Pearl River basin are excellent.

　　And in the national surface water environmental quality continued to improve behind the help of technology products, environmental monitoring instruments and modern equipment for the supervision of the outfall provides a lot of help.

　　It is reported that, with the provinces one after another to carry out outfall identification, monitoring, traceability, remediation and supervision of various tasks, many high-tech equipment has the opportunity to show their skills. For example, in recent years, the high popularity of drones, has assumed the "exploration" of different sewage problems, pipeline drones to further optimize the monitoring of the outfall pipeline work, to enhance the monitoring efficiency. In addition, such as hyperspectral water quality online monitors, handheld LIDAR, ground-penetrating radar advanced analytical instruments, but also for pollutant identification, qualitative and quantitative analysis, traceability and other work to provide direct help.

　　Not only that, some regions in the relevant monitoring work, but also further optimize the equipment and technology to enhance the efficiency. For example, the Beijing Municipal Bureau of Ecology and Environment has established a full-spectrum-based automatic water quality monitoring technology system, the development of automatic water quality monitoring "cloud quality control" technology, as well as full-spectrum-based fingerprinting traceability and other technologies to provide technical support for long-term fixed-point water ecology and habitat monitoring.

　　Today, the supervision and management of river and sea outfalls is still steadily advancing, with the help of modern instruments, in the face of the "Opinions" mentioned in the "By the end of 2023, complete the Yangtze River, Yellow River, Huaihe River, Haihe River, Pearl River, Songliao, Taihu Basin (hereinafter referred to as the seven basins) main streams and important tributaries, key lakes, key bay outfalls; promote the Yangtze River, Yellow River main streams and important tributaries and Bohai Sea outfalls," the goal should be able to get twice the result with half the effort.
