A full scale investigation was conducted by the authors at a water works that takes raw water from a polluted reservoir using conventional water treatment process to evaluate the effects of composite permanganate pretreatmcnt to control the chlorination by-products and mutagenic activity. The result demonstrated that the yield of the chlorination by-products decreased evidently by this measurement than that of conventional treatment, also the mutagenic activity of the output water transformed in or near to negative from the positive.

作者在以某受污染水库为水源的水厂进行了大型生产性对比试验,考察了高锰酸盐复合药剂预处理控制氯化消毒副产物及致突变活性的效能.试验发现,与现行的常规给水处理工艺相比,高锰酸盐复合药剂预处理系统可显著地减少氯化消毒过程中氯化副产物生成量,水的致突变活性也由阳性转为阴性或接近阴性.

By means of Ames test, the mutagenic activity of source water of Beijing Tian Cun Shan waterworks was Studied and other characteristics of the water quality decrease obviously along the waterway accommpying the risinS of mutugenicity in the water. The results of Ames test is related to the quantity of colur, turbidty,orgnnic matter and algae in the water. Chlorination generally increases the mulagenic activity, but the extent proves to be dependent on the quality of water.

利用Ames试验,以北京田村山水厂水源水为研究对象,对各输水阶段原水及其加无水样的致突活性和其它物理、化学特性进行分析,结果表明:该水厂水源水质沿着输水系统明显下降,水的致交活性升高,水源水的色度、浊度、有机物和藻类的多少与致突活性密切相关,氯化消毒导致水的致突活性增加与否与水源水质直接相关.
