"Measures with a clear base can only be effective and effective. The investigation of the river's discharge outlets has held the'niubi nose' of water conservation and control. At the same time, the formulation and implementation of the '14th Five-Year Plan' target measures is an important basic work." Fang Juanjuan, deputy director of the Shunyi District Ecological Environment Bureau, said in an interview with a reporter from Science and Technology Daily on January 8.
Since 2020, the Shunyi District has launched the pollution tracing and dynamic management project of the river inlet and outlet, and completed the three water systems of the North Canal, Chaobai River and Ji Canal, totaling 31 rivers, ditches and canals in the list of municipal river chiefs. The “inspection, testing, and tracing” work carried out preliminary investigations of 1,259 river outlets in the entire district, fully grasping the situation of river outlets in the entire district.
The first step in accurate water environment management is being steadily advanced.
Calculating the "account" for the river discharge is a difficult problem faced by the ecological environment department in setting up and managing the river discharge, and it is also a difficult problem on the road to continuous improvement of the water ecological environment in Shunyi District.
The eco-environmental department is responsible for the management of the establishment of river discharge outlets. “However, the original data varies greatly due to different statistical calibers, and there is an urgent need for a unified base to provide support for scientific policy implementation.” Fang Juanjuan said.
Starting in 2020, a special water control operation involving 6 departments and 25 territories in Shunyi District has begun.
The “integrated vertical and horizontal” investigation method based on manual + survey system apps, supplemented by technological means such as unmanned ships, took 2 months to initially investigate 1,259 river discharge outlets in the whole area, including 133 water outlets. It has a comprehensive grasp of the situation of the whole district's river discharge.
At the same time, the Shunyi District Ecological Environment Bureau actively seeks breakthroughs in water environment governance, focusing on establishing and improving the classification and hierarchical management and control of river discharge outlets, and compiled the "Shunyi District River Discharge Classification and Hierarchical Control Work Implementation Plan (Trial)" to achieve The three-in-one supervision of "Environmental Water Body-River Discharge-Onshore Pollution Source" has improved the level of refined water environmental management.
In order to scientifically arrange the surface water environment work, the Shunyi District Ecological Environment Bureau takes the principle of "water environment, water ecology, and water resources" as the principle of integrating the three waters, combining the main responsibilities of compacting the river discharge outlet with the assessment and implementing the ecological compensation mechanism. , To comprehensively improve the water environment quality within the jurisdiction.
Investigation is the basic work of accurate water environment management and can provide support for accurate policy implementation.
Only with clear bases and clear measures, Shunyi District has carried out the compilation of the "14th Five-Year Plan" for water ecological and environmental protection in key river basins in the district.
During the planning process, Shunyi District worked hard on water ecological protection, restoration and improvement of ecological elements, drafted the "Shunyi District Water Ecological Environmental Protection List", and verified that there is water and grass in the whole area in conjunction with the investigation of the river outlet. , With the length of the Yuhe section, steadily advancing towards the environmental goal of harmony between human and water.
“On the other hand, the Shunyi District Ecological Environment Bureau actively promotes the water environment management of the whole district, and gradually forms a platform management model of a map and a net from the pollution source to the river discharge, and then to the surface water.” Shunyi District Ecology The relevant person in charge of the Environmental Bureau stated that based on the data based on the investigation and monitoring of river discharge outlets, in 2021, Shunyi will install 26 sets of water quality online monitoring systems at key river discharge outlets in the whole district, so as to make the water environment monitoring network more perfect and gradually realize The fully closed-loop supervision model of “on-line monitoring of river water quality, real-time control of discharge status, and accurate and fast traceability of pollution” provides a strong guarantee for the establishment of big data integration and the realization of fine management of the water environment.
Fang Juanjuan said that by the end of 2020, the first three tasks of "inspection, testing, tracing, governance, and management" have been basically completed in terms of long-term management of river discharge outlets.
In the next step, Shunyi District will comprehensively carry out the rectification of the entire district's river outlets in accordance with the classification and grading management and control requirements.
