2011年东海县农村饮水水质检测分析报告

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 。

Detection and analysis of drinking water quality in rural areas of Donghai County in 2011

Objective To understand the quality and sanitary status of drinking water in rural areas of Donghai County,in order to provide the scientific evidence for decision-making of related departments of government.Methods Tests were conducted according to The Standard Examination Methods for Drinking Water(GB/T5750-2006),and the results were evaluated according to The Standard for Drinking Water Quality(GB5749-2006). Results A total of 332 water samples were detected in 2011,and 172 were qualified with the qualified rate of 51.8%.The qualified rate was 56.4% in the wet season and 46.9% in the dry season,and there was no significant difference between wet season and dry season(χ2=3.01,P>0.05).The qualified rates were 56.6% of the finished water and 47.0% of the peripheral water respectively,and both had no significant difference(χ2=3.09,P>0.05).The unqualified items were microbiological values,turbidity and nitrate nitrogen.Conclusions The qualified rate of drinking water in rural areas of Donghai County is low,and microbial contamination and nitrate nitrogen are high,therefore,it is necessary to strengthen the disinfection and purification of rural drinking water in order to reduce the spread of water-borne communicable diseases.
