摘　　要：应用UV+TCCA组合消毒工艺对管道分质供水系统进行了现场消毒实验。研究结果表明,应用此组合工艺将有效氯投加量控制在0．1mg/L～0．2mg/L、管网末梢水有效氯含量控制在0．02mg/L以上,可有效控制管道分质供水系统中微生物指标,并保持饮用水的较好口感。本组合工艺消毒保鲜效果稳定,生成的消毒副产物少,成本低,值得广泛推广与应用。In this paper, the disinfection combination technique of UV ＋ TCCA was applied to a dual tube drinking water supply engineering to disinfect the drinking water, The results showed that, this combination technique, in the case of effective chlorine 0.1mg/L-0.2mg/L in the supplying water and effective chlorine〈0.02mg/L in the tap water, could control effectively microorganism parameters in the dual tube drinking water supply system. The drinking water disinfected by this technique contained only a very small amount of disinfection by-products and had good taste. This disinfection combination technique gave a lower running cost, a stable disinfection effect, and was worth popularizing in the dual tube drinking water supply engineerings.
