综合指数法评价张家岩水库的水质卫生状况

HYGIENIC EVALUATION OF WATER IN ZHANGJIAYAN RESERVOIR BY USING WATER QUALITY INDEX

目的:用水质综合指数法对张家岩水库水质进行评价。方法:在3个采样点分别采集水样,样品检验按《生活饮用水卫生规范》(2001)中规定的方法进行,检测结果用水质综合指数法评价。结果:入水500m处和水库中心水样水质符合《生活饮用水卫生规范》(2001)对水源水的要求。入水口、入水500m处、水库中心水样的水质综合指数分别为1.57、0.57和0.26。结论:张家岩水库中心水质良好,可以选择作为水源水。

Objective:To evaluate water quality of Zhangjiayan reservoir by using Water Quality Index.Methods:Water specimens were obtained at three different spots;laboratory tests were done following the recommended methods in the Drinking Water Hygienic Regulation (2001),and evaluation was made using Water Quality Index.Results:The water quality of specimens taken at 500 meters away from the entry and the center area in Zhangjiayan reservoir both met the requirements for source water in Drinking Water Hygienic Regulation (2001).And the Water Quality Indices of the specimens taken at entry,500 meters away from the entry and the center were respectively 1.57,0.57 and 0.26.Conclusion:The water qulaity in the center area of Zhangjiayan reservoir was excellent,and it could be used as source water.
