摘要
目的了解广西阳朔县农村饮用水水质状况,为进一步改善水质质量,控制水源性疾病传播提供科学依据。方法采集2008—2011年阳朔县农村生活饮用水,按照国家标准进行采样、检测和评价。结果 2008—2011年共检测水样320份,合格品129份,合格率40.31%;各年度合格率分别为32.50%、38.75%、43.75%、46.25%,呈逐年上升趋势。不合格项目主要为浑浊度、肉眼可见物、菌落总数、总大肠菌群、耐热大肠菌群。枯水期与丰水期合格率差异有统计学意义(χ2=19.75,P<0.01)。出厂水和末梢水超标项目之间差异无统计学意义(P>0.05)。结论阳朔县农村生活饮用水被微生物污染严重,应加强对农村饮用水进行有效的净化消毒措施,以确保农村居民饮水安全。
[ Objective] To know the drinking water quality in rural area of Yangshuo County of Guangxi, further improve water qual-ity, and provide scientific basis for controlling the water-borne diseases. [ Methods ] The samples of rural drinking water in Yang-shuo County were collected from 2008-2011. The sampling, detection and evaluation were conducted according to the national stand-ards. [ Results] A total of 320 water samples were detected from 2008-2011, 129 were qualified with the qualified rate of 40.31%. The annual qualified rate was respectively 32.50%, 38.75%, 43.75% and 46.25%, which increased year by year. The unquali- fied items mainly included the turbidity, visible substances, total bacteria, total coliform group and thermotolerant coliform bacteri-a. There was significant difference in the qualified rate between the dry season and wet season ( X^2 = 19.75 ,P 〈 0.01 ). The differ-ence in unqualified items between the finished water and tap water was not significant ( P 〉 0.05 ). [ Conclusion] The rural drinking water in Yangshuo County is seriously polluted by microorganism. It is necessary to strengthen the effective disinfection measures in rural drinking water, to ensure the safety of drinking water among rural residents.
