since most of the tap water in china was chlorinated, it could be concluded that biopretreatment had a significant effect on reducing the mutagenic activity of drinking water.
鑒于生产中的出厂水为氯化消毒水,可以认为生物流化床预处理对降低饮用水的致突变活性有明显作用。
the mutagenic activity of the raw water, the effluent of biopretreatment, conventional process, combined process and the four chlorinated counterparts were investigated.
the results showed that the mutagenic activity of chlorinated samples was positively correlated with the concentration of algal metabolites and chlorine (p
结果表明:氯化样品的致突变活性与藻类代谢物含量及加氧量均呈正相关(p<0.05);
the mutagenic activity of drinking water could be concerned with traditional chlorination process and the pollution degree of the raw water.
饮用水致突变活性与传统的氯化工艺以及水源水污染程度有关。
the micronucleus test was used to evaluate the efficiency of the synthetic biological ponds system in huangzhou city for reducing the mutagenic activity of city sewage.
