摘要
以典型的浅水型城中湖——东大湖为对象,基于东大湖2013—2019年的水质监测数据,对其水质特征进行了分析。结果显示,2013—2019年,东大湖COD下降明显,TN,TP无明显下降,湖泊呈中度富营养化状态,TN,TP为主要超标因子,并对氮磷的时空污染特征进行了分析。在水质分析的基础上,结合周边现状调查,提出了水质改善建议,以期对同类型的湖泊治理有所帮助。
As a typical shallow lake in the city,Dongda Lake was selected as the analysis object.Based on the water quality monitoring data in 2013-2019,the water quality characteristics of Dongda lake have been analyzed.It shows that from 2013 to 2019,the COD of Dongda Lake is obviously decreased,TN and TP did not significantly decreased,the lake is in a moderately eutrophic state,TN and TP were the main exceeding-standard factors,and the characteristics of nitrogen and phosphorus pollution in time and space were analyzed.On the basis of water quality analysis,combined with the survey of surrounding current situation,suggestions for water quality improvement were proposed to help the management of same type lakes.
