哈尔滨市地下水污染特征与水质净化作用研究

松花江哈尔滨江段水质污染较重,是否可能通过入渗补给影响哈尔滨市区地下水的水质?为此,分别对松花江哈尔滨江段和哈尔滨市地下含水层的污染特征与各自的净化能力进行了分析研究.结果表明,两者的净化能力均很强,并可不断地得以自然恢复。净化作用主要表现为稀释、吸附、过滤等.保持这种自然净化能力,对保护哈尔滨市地下含水层的优良水质有十分重要的作用。

Groundwater Pollution Characteristics and Water Quality Purification in the Harbin City

The water pollution condition in the Harbin reach of the Shonghua River is very serious.Surface water may infiltrate into the aquifer and influence the groundwater quality of the Harbin-City.The purpose of this paper is to investigate the pollution characteristics of surface water and groundwater,and their purification capacities.The results show that the purification capacities of both the river reach and the aquifer are potent and can be recovered naturally.Purification mainly includes dilution,adsorption,and filtration etc.Maintaining natural purification capacities are of great importance to protecting the grouudwater quality of the Harbin City.
