秦皇岛市主要陆源入海排污口污染现状评价

The Pollution Assessment of the Major Discharge Outlets of Land Source in Qinhuangdao

根据2011年对秦皇岛周边海域环境影响较大的11个陆源入海排污口的调查结果,通过单因子污染指数及等标污染负荷相关指标的计算,分析评价秦皇岛市主要入海排污口(河流)的污染现状及主要污染源。调查结果表明,区域内所有排污口中,大蒲河排污口的污染负荷比最大;其次为滦河、新开河;所有调查指标中,总磷的污染负荷比最大,是秦皇岛近岸海域最主要的污染物。

According to the survey results of 11 mainly land - based discharge outlets in 2011, the current pollution status and the main pollution sources of Qinhuangdao city were calculatedusingsingle factor pollution index and the equal standard pollution load method. The results showed that the equal standard pollution load ratio of Dapu River was highest in the area, followed byLuan River and Xinkai River. It was noticeable that the equal standard pollu- tion load ratio of total phosphorus was highest, which indicated that the most specific pollutant in the coastal marine environment of Qinhuangdao was total phosphorus.
