Objective To assess the effect of chloramine disinfection on the formation of drinking water disinfection by-products(DBPs )and their mutagenicity.Methods The bacterial indices,chloroform and carbon tetrachloride content in the finished water samples using liquid chlorine and chloramine disinfection respectively were determined in August,2001(plentiful water season)and in March,2002(low water season).The mutagenicities of organic extracts from the water samples were tested using Ames test.The levels of DBPs...

Objective To assess the effect of chloramine disinfection on the formation of drinking water disinfection by-products(DBPs )and their mutagenicity.Methods The bacterial indices,chloroform and carbon tetrachloride content in the finished water samples using liquid chlorine and chloramine disinfection respectively were determined in August,2001(plentiful water season)and in March,2002(low water season).The mutagenicities of organic extracts from the water samples were tested using Ames test.The levels of DBPs and the mutagenic activities of water samples treated with different disinfection methods were compared.Results The total count of bateria and coliform bacteria were0/ml and0/L respectively at free chlorine con-centration of about 1mg /L in the chloraminated drinking water,which decreased81%-84%compared with those of the chlori-nated drinking water samples.The carbon tetrachloride concetration were all<0.2μg /L in chloraminated water samples and chlorinated drinking water samples.For a positive response to the TA98strain in Ames test,the lowest volume of chlorinated water was1.5L,while it was≥6.0L of chloraminated water samples.Con clu sion The use of chloramine disinfection could significantly reduce the DBPs levels and mutagenicity in drinking water.The efficacy of chloramine disinfection was favorable compared with liquid chlorine disinfection,chloramine might be a better substitute for chlorine in drinking water disinfection.

目的评价氯胺消毒对饮用水消毒副产物形成和致突变性的影响。方法分别于2001年8月(丰水期)和2002年3月(枯水期)对成都市某水厂氯胺消毒和液氯消毒饮用水的细菌学指标以及氯仿、四氯化碳含量进行了检测,对其水样的有机浓集物进行了Ames试验,然后比较两种消毒饮用水的消毒副产物含量和致突变性。结果用氯胺消毒的饮用水中余氯量约1mg/L时均未检出细菌总数和大肠菌群,且氯仿含量较用液氯消毒减少了81%~84%,两种消毒方式的饮水中四氯化碳含量均小于0.2μg/L。对于TA98菌株,液氯消毒的出厂水1.5L检出阳性反应,而氯胺消毒检出阳性反应的水样量≥6.0L。结论采用氯胺消毒可以明显降低饮用水氯化副产物的含量和致突变性,其消毒效果不亚于氯化消毒,因此,氯胺是较好的替代消毒剂。
