小柘皋河污染空间变化研究

The Study on the Spatial Variation of Small ZheGao River Pollution

农村生活污水直接排放等点源污染,农田排水等面源污染,对环境水体造成的影响越来越受到人们关注。本文以巢湖东北部的入湖河流小柘皋河为对象,通过现场布点采样,并对水样进行化学检测分析,得出水样中各污染物含量。总结得出了该河流存在的主要污染物是COD、总氮和总磷,各个指标的浓度从上游到下游整体呈下降趋势。

Both of the direct emissions of rural domestic sewage and farmland non - point pollution drew more and more attention by people. The Small Zhegao River in the northeast of Chaohu Lake as the studying object, by sampling in the spot, through tested and analysis, the main pollutants of the fiver were COD, total nitrogen and phosphorus, and each pollutant became lower alon~ the river.
