农村生活污水对滇池水质污染的潜在影响
Potential Effects of Rural Domestic Sewage on Water Quality Pollution of Dianchi
摘要
Abstract
In order to survey water quality characteristics of rural domestic sewage and potential effects on Dianchi water regime,Ziweicun village domestic sewage,well water and river water on Dianchi east bank were sampled and analyzed.The results showed that pH value of domestic sewage was normal,and conductivity and chlorophyll content were higher.Meanwhile,the DO content was lower and the COD content was higher than water quality national standard,Ziweicun village domestic sewage was polluted seriously by reductive matter.The mean difference was significant at the 0.05 level between the domestic sewage＇s DO content,COD content and the well water＇s,the river water＇s.There was a tremendous risk in Dianchi water quality security because the NH3-N and TP-P content of rural domestic sewage were too exceeded than the national standard.Furthermore,it didn＇t exceed the national standards for the Cl-、NO3——N、SO42-、Zn、As、Cd、Pb content in the domestic sewage,but the F-and Cu content surpassed the national standards in varying degrees.The mean difference was significant at the 0.05 level between the domestic sewage＇s F-content,Cu content and the well water＇s,the river water＇s.The Cd of domestic sewage wasn＇t examined and the As content was a tiny trace.The research conclusion came to that there were potential effects of rural domestic sewage around Dianchi lake on water eutrophication.关键词
