Total pollution load control and reduction measures in the Shahe River Basin around Chaohu Lake
Aiming at the problem of total pollution load control in Chaohu Lake,the Shahe River Basin,the second sub-basin of Chaohu Lake,was taken as the research object.Based on the evaluation and analysis of the hydrological characteristics,water quality damage,the distribution and intensity of pollution sources,the quantitative response relationship between land pollutant load and water quality was established.Identify key control areas in the watershed,simulate the target value of total pollution load control in the watershed through the hydrological simulation program fortran(HSPF),and develop pollution load reduction and allocation plan.The results show that under the reduction measures such as,strict implementation of Chaohu Lake Basin discharge standards for industrial point source pollution,runoff pollution in production area and domestic sewage treatment in villages and towns,increase of township sewage interception and sewerage rate to 80%,and increase of village and township pond treatment rate to 85%or above,the water quality at the outlet of each control area can meet the target assessment requirements.
