Environmental News Quick Examination 丨 The Ministry of Ecology and Environment Answer Surging News: The scientific research results of ecological environmental protection of the Yangtze River provide support for the Yangtze River reduction reduction

Since the establishment of the National Yangtze River Protection and Research Center, what are the scientific research results in the improvement of water quality improvement in the Yangtze River lakes? Is there a specific case?

On August 23, the Ministry of Ecology and Environment held a routine press conference. The Ministry of Ecology and Environment Director Zou Gongmin said in response to questions from reporters that in 2018, the Ministry of Ecological Environment established a joint research center of the Yangtze River Ecological Environmental Protection and Repair. The goal of supporting the protection and repair of the Yangtze River, guided by integrated application, and based on research results such as water projects, focusing on the development of water quality target management with phosphorus as the core, 58 cities in the basin city "one city, one strategy" and the basin ecology of the basin ecology. Research on environmental smart decision -making platforms and other studies have obtained a series of scientific research results, supporting the Yangtze River protection and repair battles.

First, the system diagnosed the total phosphorus pollution and causes of the Yangtze River Basin. The proportion of the proportion of the total phosphorus as the section of the basin is 57.3%of the section of the river basin (exceeding III); the agricultural source in the pollution source accounts for about 60%, but the industrial source entering the river is higher and the impact on the water body is more direct; Sichuan Sichuan; Sichuan; Sichuan; Sichuan; Sichuan; Sichuan; Basin, Dongting Lake Basin, Poyang Lake Basin, and the Yangtze River Delta are the prominent regions of total phosphorus pollution.

The second is to draw a picture of the Yangtze River Phosphorus pollution basin. Under the different hydrological conditions of the Yangtze River Basin, the database distribution database of the phosphorus pollution space is mainly controlled, and the dynamic pollution capacity of the urban and main control unit phosphorus pollutants is calculated.

The third is to form a strategy and plan for the control partition of the Yangtze River phosphorus pollution. Aiming at the upper, middle and lower reaches of the Yangtze River, improve the strategies such as infrastructure, strengthening sewage removal, and implementation of source separation; for the "three phosphorus" key management and control areas such as the Minjiang River, Wujiang, Dongting Lake, and Wuhan City Group, the implementation of source governance and differences Strategies such as governance; the management and control scheme of the "source analysis-process simulation-total volume distribution-pollution-mode promotion" of phosphorus pollution in the Yangtze River Basin.

The fourth is to develop a series of technologies of the Yangtze River Phosphorus pollution control. Constructing technical evaluation methods, technical screening, research and development, and integration, and 28 technologies for controlling yellow phosphorus, phosphorus, phospholosypsum, phosphorus fertilizer and phosphorus pesticide pollution.

For example, Zou Gongmin said that the Guiyang resident assistance working group conducted accurate phosphorus reduction of phosphorus reduction companies in more than 10 phosphorus -related enterprises in Guiyang Yangshui and River Basin. After more than two years of governance, the total phosphorus concentration of the outbound section in 2019 was from 0.35 in 2018 at 0.35 in 2018. MG/L decreases and stabilizes below 0.2 mg/L. This is the III standard, which has solved the problem of "boss difficulties" in total phosphorus in 60 years.

After Jiaxing's station working group conducted scientific and technological assistance to Jiaxing Nanhu, the total phosphorus concentration dropped from 0.16mg/L to less than 0.1mg/L. It basically stabilized below Class IV, with a minimum of 0.05mg/L. Starting from the end of 2020, it started from from the end of 2020 from from the end of 2020. The category is improved to Class III and stabilizes to this day.

According to Liu Youbin, a spokesman for the Ministry of Ecology and Environment, the Ministry of Ecology and Environment has recently formulated and issued the "Guidelines for the Preparation of the General Phosphorus Pollution Control Scheme of the Yangtze River Basin" to guide the provinces of the Yangtze River Basin to formulate the implementation of the total phosphorus pollution control scheme in the administrative region. Promote the control of total phosphorus pollution, and continue to improve the ability and level of water ecological environment governance in the Yangtze River Basin.

The "Guide" requires that in the basis of comprehensively summarizing the effectiveness and experience of the "Thirteenth Five -Year Plan" total phosphorus pollution control, accurately identify the problem of total phosphorus pollution in the administrative area, systematically analyze the causes of problems, and scientifically determine the target of total phosphorus pollution control. , Main tasks and guarantee measures.

At the same time, the "Guide" will focus on industrial pollution control, living pollution control, facial source pollution control, watershed ecological protection, endogenous pollution control, and river -entry pollution inspection and rectification. Comprehensive use of engineering, policies, technology and other measures to ensure the completion of the target tasks of total phosphorus pollution control.
