目的了解我市居民饮用水的卫生状况,为饮用水水质卫生提供科学依据。方法根据《生活饮用水水质卫生规范》要求,对市政供水、各乡镇集中式供水进行卫生质量的调查与分析。结果全分析水样共检测137份,合格60份,合格率43.80%,市级水厂合格率明显高于镇级水厂,x~2=5.8,P<0.05,差异有统计学意义;镇级水厂合格率明显高于村级水厂,x~2=22.24,P<0.01,差异有非常显著性。简分析水样共检测327份,合格218份,合格率66.67%。市级水厂合格率高于镇级水厂,但x~2=3.22,P>0.05,差异无统计学意义;镇级水厂合格率明显高于村级水厂,x~2=24.82,P<0.01,差异有非常显著性。结论农村水厂的水质卫生状况亟待改善。
Objective To understand the hygienic status of drinking water in our city and provide a scientific basis for drinking water quality hygiene. Methods According to the requirements of Hygienic Standard for Domestic Drinking Water Quality, the author investigated and analyzed the hygienic quality of municipal water supply and centralized water supply in towns and villages. Results A total of 137 water samples were tested and 60 were qualified, with a passing rate of 43.80%. The passing rate of municipal waterworks was significantly higher than that of waterworks at the county level, with x ~ 2 = 5.8, P <0.05. The difference was statistically significant. The town The qualified rate of water plants was significantly higher than that of village water plants, x ~ 2 = 22.24, P <0.01, the difference was very significant. Jane analysis of water samples were detected 327, 218 qualified, with a pass rate of 66.67%. The qualified rate of municipal waterworks is higher than that of the township waterworks, but x2 = 3.22, P> 0.05, the difference is not statistically significant; the qualified rate of township waterworks is obviously higher than that of village waterworks, x2 = 24.82, P <0.01, the difference is very significant. Conclusion The water quality and hygiene of rural waterworks need to be improved urgently.
