目的了解岳阳市2011-2013年城市二次供水的卫生状况及影响因素,分析问题,为保障居民饮用水水质安全提供科学依据。方法 2011-2013年,采用定期抽样的方法,每季度对岳阳市城区二次供水进行采样分析。结果2011-2013年共检测二次供水水样2 070份,其中采用水泵-水箱(水池)联合式供水水样667份,合格率58.0%;采用直接加压式供水水样1403份,合格率84.1%。结论岳阳市二次供水发展呈现明显的不平衡,采样水泵-水箱(水池)联合式供水的单位合格率偏低,应引起相关部门的足够重视。
Objective To understand the sanitary status and influencing factors of secondary water supply in cities from 2011 to 2013 in Yueyang City and analyze the problems so as to provide a scientific basis for the protection of residents’ drinking water quality and safety. Methods From 2011 to 2013, Sampling analysis was conducted on the secondary water supply in urban areas of Yueyang City on a quarterly basis using a regular sampling method. Results A total of 2 070 secondary water samples were collected from 2011 to 2013, of which 667 water samples were combined with a water pump (tank), with a pass rate of 58.0%. In addition, 1403 water samples were directly pressurized, 84.1%. Conclusion The development of secondary water supply in Yueyang City shows obvious imbalance. The passing rate of sampling pump-water tank (pool) combined water supply is low, which should be paid enough attention by relevant departments.
