摘要
陡河下游水污染较严重,对唐山市饮用水源危害较大,为了找出该区段主要污染源,共布置了七个断面,分别为一个对照断面、一个削减断面和五个控制断面。经过水样采集和各项指标实验数据的测定,表明七个采样点中氨氮均超标、COD均超标,部分测点溶解态Cd、Pb超标和色度超标。这主要是周围被微生物分解的含氮有机生活污水和电厂、电镀工业、钢厂等排放的废水所引起。
The lower dou rive was polluted severely, which seriously endangered the water quality of Tangshan city. To find the main pollution sources, seven sections were arranged, they were one comparion section, one dilution section, five controlling sections. Through water sampling and several datas monitoring, it indicated that all these seven sections were overproof of ammonia nitrogen, COD, solvent Cd and Pb and chroma, which mainly caused by nitric organic sewage and wastewater drainaged from electric power plants, electroplanting industries, steel works and so on.
