保定市府河河流中COD的变化及其污染源分析
|
摘要
为研究保定市城区府河16.8 km河段的水质情况,2018年10月29日至11月25日分河段进行了为期近1个月的采点取样工作,观察了采样点周围的景观变化,对采样点附近居民进行走访、询问,调查河流水质情况并测定其COD的浓度,实验测得各采样点COD浓度均大于30 mg/L,属于Ⅳ,Ⅴ类水质,存在水体污染现象,主要由水体富营养化造成。分析了周围景观对水质的影响、COD高峰值出现的原因、可能的污染源,并提出处理方法。
In order to study the water quality of 16.8 km of Fuhe reach in Baoding City,a sampling work was carried out for nearly one month from October 29 to November 25,2018. The landscape changes around the sampling sites were observed,and the residents near the sampling sites were interviewed. The water quality of the river was investigated and the concentration of COD was measured. The experimental results showed that the concentration of COD in each sampling site was more than 30 mg/L,which belonged to the water quality of IV and V level. There is water pollution,and the reason is mainly caused by water eutrophication. In addition,the influence of surrounding landscape on water quality,the cause of high peak value of COD,possible pollution sources were analyzed and treatment methods were given.
