浅谈污染地下水的“血液透析”式修复

Hemodialysis-like Restoration of Contaminated Groundwater

利用血液透析原理,将受污染的地下水提升至地表,根据其污染程度进行了修复,首先对其进行物理化学预处理,再利用湿地作为地球之肾在净化水质方面的作用,构建表面流人工湿地,将受污染的地下水中净化后使其进入自然水循环。此设计便于使各项指标标准化,其应用既不影响地下水文条件,又能增强污染地下水的治理透明度。

Based on both actions of wetland as kidney for purification of waste water and principles of hemodi-alysis therapy,polluted groundwater is supposed to be firstly extracted out followed by physical or chemical treatment. Afterwards, the groundwater is further purified through constructed wetland,and then enter the natural water cycle. The design facilitates standardization of various parameters is related to groundwater in addition to equipments. Its employment not only has no impact on underground hydrography, but also pro-motes transparency and prediction of prevention-control measures of groundwater pollution.
