2012年-2014年枣庄市农村集中式饮水工程水质监测分析

Analysis of the drinking water quality monitoring of centralized drinking water project in rural areas of Zaozhuang city from 2012 to 2014

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 learn the water quality and sanitary conditions of rural centralized drinking water projects in Zaozhuang, so as to provide the scientific basis for strengthening the construction of safety engineering and the management of the rural drinking water. Methods To select 60 drinking water engineering monitoring points randomly from 44 villages and towns in six areas of the whole city from 2012 to 2014. Collect the water samples of the finished water and the pipe - network peripheral water in the dry - water period and the abundant - water period. Results The total qualified rate of the water quality and sanitary conditions of rural centralized drinking water projects of Zaozhuang was 45. 86%, and the qualified rate of abundant - water period was 37.29%, and the qualified rate of dry - water period was 54.42%. The difference was statistically significant（ P 〈 0.05 ）. The qualified rate of finished water was 51.10% and the qualified rate of pipe - network peripheral wa- ter was 40.61%. The difference was statistically significant（ P 〈 0.05 ）. The qualified rate of total bacterial count was 81.77% ; the qualified rate of total Coliform group was 71.96% ; the qualified rate of heat - resistant Coliforms was 77.21%. Conclu- sion There are hidden troubles in the water quality and sanitary conditions of rural centralized drinking water projects in Zaozhuang, and corresponding measures should be taken to further strengthen the safety project construction and supervision of rural drinking water, so that to ensure the safety of the rural drinking water.
