武汉市饮用水水源生物性污染及防制对策

为保护水源，减少生物性污染对饮用水的影响提供科学依据。方法 对水源水和出厂水按GB5750－1985《生活饮用水卫生标准检验方法》检验,水源水按GHZB1－1999《地表水环境质量标准》判断水质类别，出厂水按GB5749－1985《生活饮用水卫生标准》进行评价。结果：水源生物性污染在水源污染事件中占36.8％，流域分布主要在河流、湖泊。结论：改进制水工艺，增加水质深度处理是减少生物污染的重要措施。

Biological Pollution of Source Water for Drinking in Wuhan and Its Prevention Countermeasures

Objective To provide scientific basis for prevention of source water pollution and minimization of impacts of biological pollution on drinking water quality.Methods The source water and finished water were determined based on the National Sanitary Method for Determination of Drinking Water(GB5750-1985),the sanitary quality of source water was classified based on the National Standard for Environmental Quality of Surface Water(GHZB1-1999),the sanitary quality of finished water was evaluated based on the National Sanitary Standard for Drinking Water(GB5749-1985).Results 36.8% of the accidents of source water pollution were induced by biological pollution,which mainly occured in rivers and lakes. Conclusion The important countermeasures for the minimization of source water biological pollution were to improve the process of water treatment and to develop the deep water treatment for conventional water treatment.
