摘　　要：目的分析辽宁省锦州市生活饮用水卫生监督日常监测前后饮用水质量。方法于2015年5月—2016年5月,采用随机抽样法选取城区46个二次加压供水单位、2个企业自建水厂、2个自来水厂监督前105份水样和监督后180份水样,对生活饮用水卫生监督前、后水质监测情况进行调查,分析对比实施卫生监督前后的数据,对生活饮用水卫生监督管理应用效果进行分析。结果生活饮用水卫生监督实施后,末梢水合格率为81.54%(106/130)、出厂水合格率为98.00%(49/50),明显高于卫生监督前,同时供水建设率为95.00%(19/20),明显好于卫生监督前的70.00%(14/20),各项对比差异均有统计学意义(均P<0.05)。结论加强卫生监督日常监测可提高生活饮用水质量。Objective To analyze hygienic quality of drinking water in Jinzhou municipality of Liaoning province before and after a routine hygienic supervision. Methods With random sampling, we collected 105 and 180 drinking water samples before and after a supervision at 46 secondary water supply units ,2 self-built water plants and two public wa- ter plants between May 2015 and May 2016. Hygienic quality of the water samples was detected and compared to assess the effect of the supervision process. Results After the implementation of the quantitative supervision, the qualification rate of peripheral water （81.74%, 106/130 ） and output water （98.00%, 49/50 ） increased significantly compared to those before the supervision （ both P 〈 0. 05） and the proportion of water supply capablility improvement increased from 70. 00% to 95.00% significantly among the water supply units surveyed （P 〈 0. 05 ）. Conclusion Strengthening routine hygienic supervision on water supply facilities is helpful to ensure hygienic quality of public drinking water supplied by the facilities.
