晋阳湖污染状况及根源研究

近年来我国华北第一大人工湖晋阳湖污染严重,亟待监测和治理。通过定期对湖中水样、沉积物进行采集和分析,得出晋阳湖的主要污染物为COD（Chemical Oxygen Demand）、总磷（Total Phosphorus,TP）、总氮（TotalNitrogen,TN）。污染物产生的主要原因是湖内水产的过度养殖、补水时污水的进入、内源磷的释放以及湖水自身的蒸发浓缩作用。根据上述结果,笔者提出了控制富营养化的建议。

Research on Status and Source Pollution of Jinyang Lake

Recently,Jinyang Lake,the biggest manmade lake in north China,has been polluted seriously,which need to be monitored and controlled.Through collecting and analyzing water sample and sediments in lake,the authors put forward that the main pollutants are Chemical Oxygen Demand,Total Phosphorus and Total Ni-trate.The main reasons of producing pollutants are excessive breeding of aquatic product,enter of sewage water in period of filling water,release of endogenous phosphorus and self-evaporation and concentration function.According to the above results,the authors put forward suggestions of controlling eutrophication.
