Investigation on Pollution Situation of Phosphorus in the Main rivers Entering Chaohu Lake

In order to know the pollution situation of phosphorus in the main rivers entering Chaohu lake,the monthly investigation has been conducted for continuous three years.The result shows that Shiwuli river,Nanfei river and Shuangqiao river have been polluted seriously,which have exceeded the fifth standard of "Environmental Quality Standard for surface Water" (GHZB 1-1999).Moreover,the pollution mainly comes from the industrial wastewater,living sewage and agricultural non-point pollution sources.It's believed that the eutrophic situation of Chaohu lake will be controlled only through the treatment of agricultural pollution sources,the comprehensive renovation and strengthening of the city environment as well as the reduction amount of the agricultural fertilizers.
