- Abstract:
- Due to the concentration of population and the intensity of production and living activities, the Huangjiang River basin (above the Xizha section) has prominent problems such as direct discharge of domestic sewage, non-point source pollution of livestock and poultry breeding, and insufficient self-purification capacity of the river. The water quality of the Xizha section under national control is level Ⅳ or Ⅴ of surface water standard in the dry season, and the main impact indicators are COD, NH3-N and TP. In order to achieve the goal of level Ⅲ water quality at the section, the technical route of comprehensive watershed management was systematically proposed based on the water quality assessment results and pollution source characteristics. Measures for source control and sewage interception were taken, including the elimination of direct domestic sewage outlets in towns, the treatment of livestock and poultry breeding pollution, the collection and treatment of rural domestic sewage, the internal control engineering measures such as river dredging and tributary purification, and the ecological restoration engineering measures such as riparian vegetation restoration and river channel ecological supplement. After the implementation of the project, the pollutants entering the Huangjiang River have been greatly reduced, the self-purification capacity of the water body has been significantly improved, and the water quality of the national controlled section of Xizha has reached the level Ⅲ standard for surface water.
