摘要
在含有腐殖酸的水样中加入邻苯二酚进行氯化试验,分析pH值、氯化时间、温度和投氯量等因素对生成消毒副产物的影响,结果表明:随着pH值的升高,三卤甲烷的浓度逐渐增大而卤乙酸的浓度逐渐降低;三卤甲烷和卤乙酸的浓度随氯化时间的延长而增大;高温条件下三卤甲烷和卤乙酸的生成能力均大于低温条件;在一定范围内随着投氯量增加,三卤甲烷和卤乙酸的生成量也不断增加.
The samples containing humic acid and 1,2-benzenediol were prepared to conduct chlorination test in order to analyze the impacts of some factors including pH,chlorine time,temperature and chlorine dosage on the formation of disinfection by-products.The research results indicated that with the increase of pH,trihalomethanes(THMs) formation increased but haloacetic acids(HAAs) formation decreased gradually.THMs and HAAs formation increased with chlorine time.The formation ability of THMs and HAAs were both greater at higher temperature than at low temperature.It showed a positive correlation between chlorine dosage and THMs and HAAs formation in the certain extent.
