兴化市主要河流污染断面溯源监测分析

Monitoring and Analysis of Pollution Section of Main Rivers in Xinghua City

对兴化市卤汀河冷冻厂南、兴盐界河民主村、猪腊沟吉耿3个断面水质进行溯源监测发现,导致3个断面汛期水质恶化的污染源各不相同,冷冻厂南断面周边水体主要受生活源污染,存在工业污染特征;民主村断面周边水体主要受养殖业、农业面源污染;吉耿断面周边大量的养殖塘在汛期发生漫溢会威胁该断面水质。提出了针对性的管控措施,为控制断面达到水质目标找寻最佳解决方案。

The water quality of three sections in the south of Luting river refrigeration plant in Xinghua City,Minzhu village of Xingyanjiehe river and Zhulagou Jigeng were traced and monitored.It was found that the pollution sources leading to the deterioration of water quality of the three sections in flood season were different.The water around the south section of refrigeration plant was mainly polluted by domestic sources and had the characteristics of industrial pollution.The water around the section of Minzhu village is mainly polluted by aquaculture and agricultural non-point sources.A large number of aquaculture ponds around the Jigeng section overflow in flood season,which will threaten the water quality of the section.Targeted control measures are put forward to find the best solution for the control section to achieve the water quality goal.
