The impact of the South-to-North Water Diversion Project on the environment? Mainly related to the environment!

Before the implementation of the South-to-North Water Diversion Middle Route Project, the average annual discharge flow of the Danjiang Reservoir was 38.5 billion. After the implementation of the project, 9.5 billion cubic meters of reservoir water will be diverted, accounting for about 27% of the discharge flow, and only the Xiangfan section The city's 36 main sewage outlets that directly discharge into the Han River discharge about 3.5 billion cubic meters of sewage into the Han River every year. In addition, the Xiangfan section receives Xiaoqing River and Tangbai River, which accounts for 6.454 billion cubic meters of Category 5 super water. The water flow in the Qianjiang River is adjusted. Large, these sewage can be diluted and purified by the river water itself. After the water transfer, the water flow is small, the flow speed is slowed down, and the river water's own purification ability is weakened, which will intensify the pollution of the Han River, cause serious ecological disasters, threaten the safety of people's life and production in the middle and lower reaches of the Han River, and will make the Han River worse. It has become a new Huaihe River. The state's compensation projects for the middle and lower reaches of the Han River - diversion of the river to Han and other projects can only solve the problems of the middle and lower reaches of the counties and cities below the Shayang section of the Han River, while Gucheng, Laohekou and Xiangfan below the Danjiang River and above the Shayang section , Xiangyang, Yicheng, Zhongxiang, etc. are important industrial and agricultural cities along the middle reaches of the Han River. The serious deterioration of water quality after water diversion will bring endless troubles to people's lives and industrial and agricultural production in these counties and cities. The country is requested to carefully consider how to solve this problem. , must not let it become the new Huaihe River and cause ecological disaster.
