The identification of certain organic compounds in drinking water has led water treatment specialists to be increasingly concerned about the eventual risks of such pollutants to the health of consumers. Our experiments focused on the role of ozone and granular activated carbon in removing mutagenic compounds and precursors that become toxic after chlorination. We found that if a sufficient dose of ozone is applied, its use does not lead to the creation of mutagenic compounds in drinking water and can even eliminate the initial mutagenicity of the water. The formation of new mutagenic compounds seems to be induced by ozonation that is too weak, although these mutagens can be removed by GAC filtration. Ozone used with activated carbon can be one of the best means for eliminating the compounds contributing to the mutagenicity of water. A combined treatment of ozone and activated carbon also decreases the chlorine consumption of the treated water and consequently reduces the formation of chlorinated organic compounds.
饮用水中某些有机化合物的鉴定使水处理专家越来越担心此类污染物对消费者健康的潜在风险。我们的实验重点关注臭氧和颗粒活性炭在去除诱变化合物以及氯化后会变成有毒物质的前体方面所起的作用。我们发现，如果使用足够剂量的臭氧，它不会导致饮用水中产生诱变化合物，甚至还能消除水最初的诱变性。新诱变化合物的形成似乎是由过弱的臭氧化作用诱导的，不过这些诱变剂可通过颗粒活性炭过滤去除。臭氧与活性炭联用可能是消除导致水具有诱变性的化合物的最佳方法之一。臭氧和活性炭的联合处理还能降低处理后水的氯消耗量，从而减少氯化有机化合物的形成。
