摘　　要：近年来,饮用水二次污染问题受到人们的广泛关注。自来水厂的出水水质已经达标,而经由供水管网到达用户龙头端时往往存在水质下降的现象。用户端供水管网较市政管网更容易发生二次污染问题。因此,用户端管道清洁技术的研究对防止饮用水二次污染、保障居民饮用水安全方面具有重大意义。介绍了用户端自来水管网的污染现状,分析对比传统管道清洁技术的优劣,对用户端管道清洁技术的前景进行了展望。In recent years,the problem of secondary pollution of drinking water has been widely concerned.The effluent quality of waterworks has reached the standard,but when it reaches the tap end of users through the water supply network,the water quality often drops.The problem of secondary pollution is more likely to occur in the user end water supply network than in the municipal network.Therefore,the research on the cleaning technology of user end pipeline is of great significance to prevent the secondary pollution of drinking water and ensure the safety of drinking water.This paper introduces the pollution status of the user end water pipe network,analyzes and compares the advantages and disadvantages of traditional pipe cleaning technology,and prospects the prospect of the user end pipe cleaning technology.
