The Study on Technique of Basin Water Quality Target Management I: Pollutant Total Amount Control Technique in Control Unit

Abstract

The current domestic and foreign systems of water pollution control technology were summarized.Emphatically,the technical framework and advantages of TMDL program of USEPA,regarded as the very typical technique of water quality management in the world,were systematically introduced,which can offer good reference to basin water quality target management in China.Based on the principles of human fundamental,emphasis on ecological and type,by region,by grade and by term,the technique system of basin water quality target management was constructed with the goal of keeping the health of water eco-system.The implications and traits of this technique system were explained.The methods of control unit-based pollutant total amount control were analyzed,such as the ecological zoning of water environment,the construction of water quality standard system,the choice of water pollution control unit,the calculation of actual and permitted pollutant load,the allocation of pollutant load and so on.Finally, four suggestions were brought forward for actualizing the basin water quality target management system.
