Water quality target control method for northern large reservoir basin

Abstract

The invention discloses a water quality target control method for a northern large reservoir basin. A water quality target is determined through the functional zoning of the ecological environment and the functional zoning of the water environment, and pollution source control measures are determined through controlling the quantity of pollutants entering the reservoir. In the invention, the water quality of the basin and the water ecological safety are organically combined, pollution is controlled based on the evaluation of the structure and function of the water ecosystem, and a unified total pollutant control system is established. Both point source control and non-point source pollution load reduction are taken into consideration, and the rationality and fairness of pollution load distribution are ensured. A multi-level classification system is established based on the water quality condition of the reservoir. All layers are linked, and implementation is carried out layer by layer. Classified control on reservoir basin water quality target management is reflected. Finally, water quality target management is implemented in all kinds of water quality target control.

Description

technical field [0001] The invention belongs to the field of ecological environment protection of water sources, and in particular relates to a control method aiming at the water quality target of large reservoirs in the north. Background technique [0002] Over the years, my country has successively carried out research on water function zoning, water quality mathematical models, water environment capacity, sewage permit management system, and comprehensive planning for water pollution prevention and control in river basins. Combining water pollution prevention and control planning with total volume control technology, gradually form a water quality management technology system that focuses on pollutant targets, supplemented by capacity total volume control and industry total volume control. At the same time, it has laid a solid foundation for the establishment of the basic system of water environment management in my country. However, since the technical basis of implemen...

Problems solved by technology

However, since the implementation of technical basis is a method of water quality management based on total target control, it does not closely combine water quality targets and pollutant control in a real sense, and it is difficult to meet the needs of my country's future water environment management.

[0003] Compared with foreign water quality management technical systems, my country's target total control technology research is still weak in some aspects, and the water quality target management system based on administrative regions cannot solve the gradually intensified administrative cross-border pollution disputes, so the performance There are shortcomings that do not meet the requirements of future water quality management, thus restricting the further development of my country's water environment management research
