不同消毒方法在管道分质供水工程中的应用比较

Comparison of different disinfection techniques for dual purpose pipe watersupply system

管道分质供水常用的消毒方法有臭氧法、紫外(UV)法、TCAA法、二氧化氯(ClO2)法及组合工艺法等,对不同消毒方法在管道分质供水工程中的应用情况进行比较研究。结果表明,在不同消毒方法中,应用TCCA+UV与ClO2+UV组合工艺法,只要控制用户终端净水中的消毒剂浓度在0.05mg/L时,对管道分质供水消毒具有较好的效果,同时可以保持水质具有良好的口感。

O3, UV, TCCA, ClO2, and the combination of TCCA ＋ UV and ClO2 ＋UV approaches are common disinfection techniques in dual purpose pipe water supply system. This study is focused on the comparison of these techniques and results indicated that the combination of TCCA＋UV and ClO2 ＋UV technique produced the best result if keeping the chlorine concentration at 0. 05 mg/L at user terminal and it also achieved better taste. With stable performance, this combination technique is recommendable for application.
