目的了解东海县农村生活饮用水安全卫生状况,为政府及相关部门制定规划和决策提供科学依据。方法按照生活饮用水卫生标准检验方法(GB/T5750-2006)进行检验,按生活饮用水卫生标准(GB5749-2006)进行评价。结果 2011年共检测水样332份,合格172份,合格率51.8%,枯水期、丰水期合格率分别为56.4%、46.9%,差异无统计学意义(χ2=3.01,P>0.05),出厂水、末梢水合格率分别为56.6%、47.0%,差异无统计学意义(χ2=3.09,P>0.05),不合格项主要为微生物指标和浑浊度、硝酸盐氮。结论东海县农村生活饮用水水质合格率偏低,主要为微生物污染和硝酸盐氮等偏高,必须加强对农村饮用水进行消毒和净化处理,达到降低介水传染病的传播、保障农村居民饮水卫生的目的 。
Objective To understand the safety and health status of drinking and drinking water in rural areas in Donghai County and to provide a scientific basis for the government and relevant departments to make plans and make decisions. Methods According to the drinking water health standard test method (GB / T5750-2006) for testing, according to drinking water health standards (GB5749-2006) for evaluation. Results A total of 332 water samples were tested in 2011, with a pass rate of 51.8%. The pass rates in dry season and wet season were 56.4% and 46.9% respectively, with no significant difference (χ2 = 3.01, P> 0.05) The qualified rate of water and terminal water were 56.6% and 47.0%, respectively, with no significant difference (χ2 = 3.09, P> 0.05). The unqualified items were mainly microbial index, turbidity and nitrate nitrogen. Conclusion The qualified rate of rural drinking water in Donghai County is low, mainly because of high microbial pollution and nitrate nitrogen. It is necessary to strengthen the disinfection and purification of drinking water in rural areas so as to reduce the spread of water-borne infectious diseases and ensure the drinking water quality of rural residents The purpose of health.
