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 health status of drinking water of rural residents in Luohe city and provide scientific basis for rural water improvement work. Methods According to “2011 Shandong province rural drinking water quality sanitary monitoring technical program” of Luohe city drinking water sources in rural areas, the basic situation of rural centralized water supply, centralized monitoring point of rural water supply and the results of the water quality report form the basic Investigation of the situation, and 100 rural centralized water supply monitoring points sampling and testing, the test results were statistically analyzed. As a result, most of the water supply projects in Luohe City belonged to the projects with water supply capacity of less than 500 t and water supply population of less than 5,000 persons. The passing rates of water quality at withered and wet periods were 85.5% and 72.5% respectively, of which, (P0.05). The percentages of the qualified rate of factory water and terminal water were respectively 70.0% and 74.0% in wet season, respectively, and the difference was statistically significant (P <0.05) There was no significant difference in the qualified rate of water (P> 0.05). The main indicators of unqualified water quality monitoring were total number of colonies, total coliforms, heat-resistant coliforms, manganese, chloride, total hardness and fluoride. Conclusion Luohe City, rural population centralized water supply coverage is low, we must speed up the construction of rural centralized water supply projects to further strengthen the water disinfection and supervision and monitoring.
