摘要
二氧化氯是一种新型的消毒剂，可以代替液氯用于饮水消毒。作者通过实验对比了二氧化氯和氯气对氯仿形成的影响，结果表明：加氯是饮水中形成氯仿的主要原因，而投加二氧化氯则不会形成致癌岐变的氯仿。
Conventional disinfection by the chlorination of drinkingwater has been considered to be the safe method for more thaneighty year. In recent years, the scientific interest intrihalomethanes (THMS) caused by cholorination has increasedsince their harmful effects on the consumers' health. For thisreason, many methods have been tried to avoid THMS. Usingchlorine dioxide(CIO2 ) as a new disinfectant may be the bestway. This study was conducted to compare the effects oftreatment by using different disinfectants C12 and CIO2. Thestudy demonstrates that: Chlorination is the main factor offorming THMS in drinking water. Persistant time, disinfectantdosage effects the concentration of THMS; however, THMS arenot found in raw water samples and samples applying CIO2.
