上海河道水环境变化成因分析——以上海某河道为例

Mechanism of River’s Water Quality Change in a River of Shanghai

2017年9月至2018年8月,以上海某条河道为研究对象,基于外源排污、内源污染、河道治理和水质的关系等因素进行水环境变化成因分析,结果表明,外源污染是河道水质恶化的主要原因;河道治理期间水质会产生恶化,但治理完成后水质会好转;不进行河道调水的情况下,底质和水质的污染物交换作用不明显。

From September 2017 to August 2018,a river course in Shanghai was taken as the research object,and the causes of water environment changes were analyzed based on factors such as external pollution discharge,internal pollution,the relationship between river course management and water quality.The results showed that external pollution was the main cause of river course water quality deterioration.Water quality will deteriorate during the river course treatment,but it will improve after the treatment is completed.Under the condition of no river diversion,the pollutant exchange between bottom sediment and water quality is not obvious.
