摘要
目的了解石家庄市某县区8年间农村集中式供水水质卫生状况,为政府有针对性采取措施提供依据。方法选取有代表性的监测点,现场调查水源类型、取水方式及覆盖人口,依据国家有关标准进行水样的采集、保存、运输、检测和评价。结果 2008—2015年共采集该县区农村集中式供水水样888份,水质达标率为54.73%;枯水期水质优于丰水期,差异有统计学意义(χ~2=14.254,P<0.05);不同采集位置水质达标率差异无统计学意义(χ~2=0.291,P>0.05);主要不达标指标为总硬度、总大肠菌群、硝酸盐等。结论该地区农村饮用水达标率仍相对较低,需科学选择水源,完善净水处理工艺,规范饮用水消毒,以尽最大可能保障农村饮水卫生安全。
[Objective] To understand the sanitary conditions of rural centralized water supply in a District of Shijiazhuang City in 8 years, provide the basis for government to carry out the targeted measures. [Methods] The representative monitoring points were selected to investigate the water source type, water intake method and covering population. The collection, preservation, transportation, testing and evaluation of the water samples were performed according to the relevant national standards. [ Results ] Totally 888 water samples were collected in this district from 2008-2015, and the qualified rate of rural centralized water supply was 54.73%. The water quality in dry season was higher than that in rainy season, and the difference was statistically significant （xE=14.254,P〈O.05）. There was no statistically significant difference in qualified rate among different types of water sample （X2=0/291,P〉0.05）. The main unqualified indexes were total hardness, total coliform bacteria, and nitrate. [Conclusion] The qualified rate of rural drinking water is relatively lower in this area. It is necessary to scientifically choose water source, improve water purification process, and standardize the drinking water disinfection, to ensure the safety and health of rural drinking water.
