目的:了解河池市金城江区农村饮水安全工程水质状况,为政府及相关部门对农村饮水安全工程的建设与管理提供科学依据。方法:按照《生活饮用卫生水标准检验方法(》GB/T5750-2006)进行检测,按照《生活饮用水卫生标准》(GB5749-2006)评价。结果:229份农村饮水安全工程水样总合格率为26.6%,年度合格率差异有显著性(χ2=18.6、P<0.05),枯水期与丰水期水质合格率差异有显著性(χ2=46.88、P<0.05),出厂水与末梢水水质合格率差异无显著性(χ2=0.012、P>0.05),不合格项目主要为菌落总数、总大肠菌群、耐热大肠菌群。结论:辖区内农村饮水安全工程水质合格率低,受微生物污染非常严重,加强对农村饮水安全工程管理和饮水消毒刻不容缓。
Objective: To understand the water quality of rural drinking water safety project in Jinchengjiang District, Hechi City, and to provide scientific basis for the construction and management of rural drinking water safety project by the government and related departments. Methods: According to Standard Test Method for Domestic Drinking Water (“GB / T5750-2006), it was evaluated according to” Sanitary Standard for Domestic Drinking Water "(GB5749-2006). Results: The total qualified rate of 229 drinking water safety projects in rural areas was 26.6%. There was a significant difference in annual qualification rates (χ2 = 18.6, P <0.05), and there was a significant difference in pass rates between dry season and wet season (χ2 = 46.88 , P <0.05). There was no significant difference in qualified rate between the ex-factory water and the peripheral water (χ2 = 0.012, P> 0.05). The unqualified items were mainly the total number of colonies, total coliforms and heat-resistant coliforms. Conclusion: The water quality passing rate of rural drinking water safety project in the area is low and polluted by microorganisms is very serious. It is urgent to strengthen the management of drinking water safety project in rural areas and water disinfection.
