目的了解枣庄市农村集中式饮水工程水质卫生状况,为加强农村饮水安全工程建设和管理提供科学依据。方法2012年-2014年在全市所辖的6个区(市)44个乡镇随机抽取60个饮水工程监测点,分别于枯水期和丰水期采集出厂水和管网末梢水水样。结果枣庄市农村集中式饮水工程水质总体合格率为45.86%。丰水期的合格率为37.29%,枯水期合格率为54.42%,差异有统计学意义(P<0.05);出厂水的合格率为51.10%,末梢水的合格率为40.61%,差异有统计学意义(P<0.05)。细菌总数的合格率为81.77%,总大肠菌群的合格率为71.96%,耐热大肠菌群的合格率为77.21%。结论枣庄市农村集中式饮水工程水质尚存隐患,应采取相应的措施,进一步加强农村饮水安全工程建设和监督检测,确保农村居民的饮水安全。
Objective To understand the status of water quality and sanitation of rural centralized drinking water project in Zaozhuang City and provide scientific basis for strengthening the construction and management of rural drinking water safety project. Methods From 2012 to 2014, 60 drinking water project monitoring points were randomly selected from 44 townships in 6 districts (cities) under the jurisdiction of the whole city to collect the water samples of the ex-factory water and the pipe network at the dry season and the wet season respectively. Results Zaozhuang rural centralized drinking water quality of the overall pass rate of 45.86%. The pass rate in wet season was 37.29%, the pass rate in dry season was 54.42%, the difference was statistically significant (P <0.05). The pass rate of ex-factory water was 51.10% and the pass rate of peripheral water was 40.61% Significance (P <0.05). The total pass rate of bacteria was 81.77%, the total pass rate of coliform bacteria was 71.96%, the pass rate of heat-resistant coliform bacteria was 77.21%. Conclusion Zaozhuang City, rural centralized drinking water quality remains hidden dangers, should take appropriate measures to further strengthen the rural drinking water safety project construction and supervision and testing to ensure that rural residents drinking water safety.
