鲁北平原一多年排污河渠对两侧浅层地下水水质的影响分析

Analysis on Influence of the Multiple-year Sewage Canals to Shallow Groundwater Quality in Its Both Side in the Lubei Plain

为了阐明平原区排污河渠对地下水水质的影响程度和影响范围,以鲁北平原一条未采取防渗措施的多年排污河渠为例,进行了河渠污水对两侧浅层地下水污染机理的研究。通过Mg2+、Cl-、1,2-二氯乙烷等主要污染指标在排污河渠两侧的扩散规律研究,初步确定排污河渠对两侧浅层地下水综合质量的影响范围约为100 m。此结论为平原区浅层地下水的防污、治污提供了一定的参考依据。

In order to Clarify the impact degree and scope of the sewage canals on the groundwater quality in the northern Shandong plain,it takes a multiple-year sewage canals not adopted the seepage control measures for an example,studies the sewage canals on both sides of the mechanism of groundwater pollution.Through the spreading rules of Mg^2＋,Cl^-,1,2-dichloroethane and other major pollution indicators on both sides of the sewage canals,the artiCle initially identified that the influenced scope of the comprehensive quality of shallow groundwater on the both sides of the sewage canals is about 100m.This conClusion provides some reference for the shallow groundwater pollution prevention,pollution control.
