| 摘 要： | 以供水管网末端广泛使用的PPR管和新型不锈钢塑复合管为研究对象，对其卫生安全性进行了比较研究。检测项目分为基本检测项目和不同材质的增测项目共29项。应用异养菌平板计数方法对不同管材管壁微生物附着生长特性进行了研究。结果表明2种管材作为生活饮用水输配水设备，卫生安全性是合格的，管壁对水质的影响随着浸泡时间增加而增加。由于不锈钢塑复合管对水质影响和管壁微生物数量都小于PPR管，所以其具有更好的稳定性，抑菌效果要优于PPR管，对水质的卫生安全有更高的保障。

| Abstract: | PPR pipe, which was widely used in the secondary water supply system and combined stainless steel plastic pipe were evaluated for their hygienic safety characteristics. These 29 test indexes were divided into basic indexes and additional indexes. Heterotrophic bacteria plate count was used to observe the attached bacteria on the inner wall of these two different pipes. The results show that these two kinds of pipes are qualified for their hygienic safety as drinking water distribution equipment. The effects of pipe wall on water quality increase with the immersion time. Combined stainless steel plastic pipe is better than PPR pipe for less impact on water quality, less biofilm microbes attached, better stability, superior antibacterial effects. The combined stainless steel plastic pipe can give a better hygienic safety protection for drinking water. |
