摘　　要：针对PP-R管内壁藻类滋生导致饮用水二次污染的问题,论述了PP-R给水管内壁藻类滋生问题的危害和产生原因,分析了管内壁的藻类种类,并提出了相关处理措施及建议。分析结果表明,应强化饮用水加氯消毒工作;室内给水管道可选择薄壁不锈钢管、铜管等管材;建议使用绿色或灰色PP-R管,以抑制藻类生长。这些措施及建议可为其他供水企业处理同类问题提供参考。Aimed at the issues of secondary breeding in inner wall of PP-R pipeline, the damage contamination in drinking water caused by algae and causes of algae breeding were discussed, the algae species were analyzed, and the suggestion of relevant treatment measures was put forward. The analysis results indicated that chlorination disinfection of drinking water was enhanced, thin-walled stainless steel pipes and copper pipes were selected in indoor water supply pipeline, and the green or grey PP-R pipelines were used in order to inhibit algae growth. These measures and suggestions could provide reference for the treatment of similar issues in other water supply enterprises.
