云南通海县岳家营暗河管道水质评价

岳家营暗河的水流多来自于通海杞麓湖水,30年前岳家营暗河水质相对较好,基本上符合饮用水标准.但近年来由于杞麓湖受到污染,水质达到劣Ⅴ类,导致岳家营暗河地下水受到污染,主要超标项有汞、镉、亚硝酸盐和氰化物等,已不符合生活饮用水标准.针对地下水污染加剧状况,建议：1.沿湖控制污水排放;2.加强水质监测;3.提高公众环境意识并加强地下水保护宣传力度.

THE ASSESSMENT OF TUBE WATER IN YUEJIAYING BURIED RIVER IN TONGHAI,YUNNAN

The waters of Yuejiaying buried river are mainly derived from Qiluhu lake, Tonghai. The waters of Yuejiaying buried river were better relatively 30 years ago, which could basically meet the driking standard. Nevertheless, the waters of Qiluhu lake have been degraded to class bad-V because of pollution in recent years. The main over-standard items are Hg, Cd, nitrite and cyanide, etc. couldn＇t meet the drinking standard. In the light of pollution intensification of underground water, we put forward the following suggestion, 1. waste water drainage control of lakeshore ; 2. intensification of water supervision ; 3. improvement of public environment con- sciousness and intensification of underground water protection propaganda.
