目的:了解天台县农村居民饮用水卫生状况。方法:水样的检验按GB/T5750-2006《生活饮用水标准检验方法》,检测结果按GB5749-2006《生活饮用水卫生标准》进行评价。结果:共检测284份水样,合格154份,总合格率为54.2%,不合格项目主要为余氯、菌落总数、总大肠菌群、耐热大肠菌群、浑浊度、锰和铁,合格率分别为60.9%、65.5%、64.4%、64.8%、87.0%、95.4%和97.9%,其余指标的合格率均在98%以上;集中式供水与分散式供水合格率分别为59.3%和41.2%,两者有显著性差异(χ2=7.55,P<0.01);冬春季与夏秋季的监测合格率分别为72.7%和42.5%,两者差异非常显著(χ2=24.76,P<0.01)。结论:天台县农村饮用水水质监测合格率较低,特别是微生物污染较严重,必须加强净化和消毒。
Objective: To understand the health status of rural residents drinking water in Tiantai County. Methods: The water sample test according to GB / T5750-2006 “drinking water standard test method”, test results according to GB5749-2006 “drinking water health standards” for evaluation. Results: A total of 284 water samples were tested and 154 were qualified, with a total pass rate of 54.2%. The main unqualified items were residual chlorine, total number of colonies, total coliforms, heat-resistant coliforms, turbidity, manganese and iron, qualified The rates of qualified water supply and decentralized water supply were 59.9%, 60.5%, 65.4%, 64.8%, 87.0%, 95.4% and 97.9%, respectively. The pass rates of centralized water supply and decentralized water supply were 59.3% and 41.2% %, The difference between the two was significant (χ2 = 7.55, P <0.01). The pass rates in winter and spring and summer and autumn were 72.7% and 42.5% respectively, with significant difference between them (χ2 = 24.76, P <0.01). Conclusion: The qualified rate of water quality monitoring of rural drinking water in Tiantai County is relatively low, especially the microbial pollution is more serious. Therefore, the purification and disinfection must be strengthened.
