摘要
采用吹洗曝气和跌水曝气对消毒后饮水中的氯仿的去除效果较好。其消除率与时间、气体流量、水温成正比，水量越大，水中氯仿浓度越高，处理后残余氯仿越高。两种方法对三卤甲烷（ＴＨＭｓ）各组分的消除效果表明，其消除效果随着各组分沸点的升高而降低。两种方法对军用水壶中消毒后产生的ＴＨＭｓ都有较好的消除效果，吹洗５分钟，跌水１０分钟都可以将ＴＨＭｓ降到１００μｇ／Ｌ以下。采用人工吹洗曝气３分钟，可使消毒水样中的ＴＨＭｓ降到１００μｇ／Ｌ以下。
The chlorform formed in water was removed effectively by aeration and drop-aeration.The removal ratio in creased with cantact time,aeration-flow and water temperature and decreased with rise of boiling point of trihalomethames(THMs).THMs formed in canteen can be removed effectively by these two methods.Aeration 5 min. or drop-aeration 10 min.decreased THMs under 100μg/L.The artificial aeration 3 min. decreased THMs under 1 00μg/L in water samples.
