摘　　要：金属管道在我国给水管网系统中广泛使用,腐蚀问题增加了金属管道的使用成本。微生物腐蚀是管道腐蚀产生的重要原因。而管壁生物膜是给水管网系统中微生物的主要来源,并带来许多公共卫生问题。重点论述金属给水管道生物膜的形成特点,以及由生物膜的形成带来的生物膜脱落、消毒副产物(DBPs)生成、管道腐蚀等危害。总结影响金属给水管道生物膜形成的因素,在此基础上讨论实际可行的控制策略。最后,从监测和遏制管道生物膜形成等方面做出了展望。Metal pipes are widely used in drinking water distribution system(DWDS)in China.The corrosion problem increases the use cost of metal pipes.Microbial corrosion is an important cause of pipeline corrosion.Pipe wall biofilm is the main source of microorganisms in DWDS and brings many public health problems.We focused on the formation characteristics of biofilm in metal water supply pipeline,the detachment of biofilm,the production of disinfection by-products(DBPs),corrosion of pipe and so on.The factors affecting the formation of biofilm in metal water supply pipeline were summarized,and the practical control strategies were discussed on this basis.Finally,the future research direction was put forward from the aspects of monitoring and curbing the formation of pipe biofilm.
