城镇排污河道地下水有机污染研究

Study on Groundwater Organic Pollution of the Sewage River in City

为阐明排污河道对地下水水质的影响程度和影响范围,以德州市某排污河道为例,进行河道污水对沿岸土壤和地下水有机污染状况研究。结果表明,排污河渠两侧的浅层地下水已经受到较严重的污染,污染物主要为三氮、重金属和邻二氯苯等有机污染物;土壤中多吸附有机氯农药、多氯联苯和苯并芘等分子量较大的有机组分。

In order to clarify the influence degree and scope of the sewage river to groundwater quality,taking one sewage channel of Dezhou as an example,effects of sewage river on coastal soil and groundwater organic pollution were studied.The results showed that the shallow groundwater has been seriously polluted on both sides of the sewage,the main pollutants include 3-nitrogen,heavy metal and chloroben,etc.Chlorinated pesticides,polychlorinated biphenyls and benzopyrene and other organic components of larger molecular weight are absorbed in soil.
