摘要
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.
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.
