对二种家庭自来水管材早晨首次开启水龙头时水样监测指标的检测,得出二种管材水质中理化成分和细菌群落的合格率与超标率,通过对结果的分析,提出家庭自来水管管材采用的建议。由于自来水管材发展的原因,岳阳市区房龄10年以上住房居室内供水支管大多采用镀锌铁管,10年内所建房一般采用聚氯乙烯管材为供水支管,这二种管材都对自来水水质有一定影响,镀锌铁管锌层附着力较差,极易造成局部镀锌层脱落而产生锈蚀,
The water quality monitoring indexes of the two kinds of household water pipes when the taps were turned on for the first time in the morning were tested to obtain the qualified rates and the excessive rates of the physical and chemical compositions and the bacterial communities in the two kinds of pipe water qualitys.According to the results, Suggest. Due to the reasons for the development of water pipe, Yueyang urban area more than 10 years of age housing for indoor water supply pipe mostly galvanized iron pipe, built within 10 years generally use polyvinyl chloride pipe for water supply pipe, these two kinds of pipe have a certain quality of tap water Affect the galvanized iron pipe zinc coating adhesion is poor, can easily lead to partial loss of galvanized layer and rust,
