抽水截流防治地下水中六价铬污染

Drawing Water to Control Ground Wa ter Pollution from Cr^(6+).

就城市工业区地下水环境受六价铬严重污境的情况,根据该地区环境水文地质条件,在污染中心地带采用抽水截流方法,使地下水中六价铬污染大幅度下降,经过6年防治,其污染范围由0.321km^2下降到0.032km^2,居民生活饮用水供应恢复正常,仅4号水源井已创税利30万元。

Taking the environmental hydrological and geological conditions of an Cr3+ polluted urban industrial area into account, A countermeasure, i.e. drausing water from underground in the center of the area to cut off underground streams, was taken to reduce the level of pollution of ground water from Cr6+. After 6 years practice, the polluted area was reduced from 0.321km2 to 0.032km2 and the drinking water supply was back to normal.
