摘要
目的通过了解漯河市农村居民生活饮用水卫生状况,为农村改水工作提供科学依据。方法按照《2011年河南省农村饮用水水质卫生监测技术方案》对漯河市农村生活饮用水水源类型、农村集中式供水基本情况、农村集中式供水监测点情况和水质结果报告表中的内容进行基本情况调查,并对100处农村集中式供水监测点进行采样检测,对检测结果进行统计分析。结果漯河市大部分供水工程属于供水能力不足500 t和供水人口小于5 000人的工程;监测点枯、丰水期水质合格率分别为85.5%、72.5%,其中,枯水期出厂水、末梢水合格率分别为86.0%、85.0%;丰水期出厂水、末梢水合格率分别为70.0%、74.0%,枯、丰水期出厂水合格率比较,差异有统计学意义(P<0.05);末梢水合格率比较,差异无统计学意义(P>0.05);水质监测不合格指标主要有菌落总数、总大肠菌群、耐热大肠菌群、锰、氯化物、总硬度、氟化物。结论漯河市农村人口集中式供水覆盖率较低,要加快农村集中式供水工程的建设,进一步加强饮水消毒和监督监测。
[Objective]To understand the sanitary condition of rural drinking water in Luohe City,provide scientific basis for water supply improvement in rural area.[Methods]According to the Monitoring Project for Sanitary Condition of Drinking Water in Rural Area of Henan Province in 2011,the basic condition of rural drinking water in rural area of Luohe City were investigated,which included type of water source,basic information of centralized water supply,situation of monitoring points for centralized water supply and reports of water quality.The water samples collected from 100 monitoring points of centralized water supply were detected,and the results were analyzed statistically.[Results]The capacity of most water supply projects in Luohe City was less than 500 tons,and the water-supplied population was less than 5000.The qualified rate of water quality in dry season and rainy season was 85.5% and 72.5% respectively.The qualified rate of finished water and tap water in dry season was respectively 86.0% and 85.0%,while that in rainy season was respectively 70.0% and 74.0%,the difference in qualified rate of finished water between dry season and rainy season was significant（P0.05）,and the difference in qualified rate of tap water was not significant（P0.05）.The unqualified indexes mainly included total bacterial count,total coliform group,thermotolerant coliform bacteria,manganese,chlorides,total hardness and fluorides.[Conclusion]The coverage rate of centralized water supply is low in rural area of Luohe City.It is urgent to construct centralized water supply projects in rural area,and strengthen disinfection and supervisory monitoring of drinking water.
