摘要
目的了解福建省农村居民生活饮用水卫生状况,为制订改水决策提供科学依据。方法于2004年3—5月,选择福建省14个县作为农村生活饮用水监测县(市),每个县设约10个监测点,共计144个监测点。对农村生活饮用水水源类型、取水方式、水质处理情况及其相应的饮用人口数等进行现场调查。按照《生活饮用水卫生规范》(2001)对水样进行采集、保存和检测,根据《农村实施<生活饮用水卫生标准>准则》进行分级和评价。结果14个县农村居民有61.29%以地下水为水源,38.71%以地面水为水源;从供水方式上看,有58.24%饮用集中式供水,41.76%饮用分散式供水。共检测水样288件,合格76件,合格率为26.39%。色度、浑浊度、pH值、铁、锰、氟化物、硝酸盐氮、氯化物、总大肠菌群、细菌总数超标率分别为0.35%,0.35%,14.75%,1.75%,2.78%,0.69%,3.12%,0.35%,53.47%,21.18%,总硬度、砷、硫酸盐均合格。地面水水样合格率[35.38%(46/130)]高于地下水水样合格率[18.99%(30/158)],差异有统计学意义(P<0.01)。结论福建省农村部分居民生活饮用水水质较差,受微生物污染严重。
Objective To know the drinking water quality in the rural areas in Fujian Province in order to provide the scientific basis for water improvement in the rural areas. Methods Fourteen counties were selected in Fujian, 2004, 10 monitoring sites in each county based on the population proportion of different drinking water types. Sixteen indicators were determined for every water sample. Results In the 14 investigated counties, 38.71% of total population drinking water supplied with surface water, and 61.29% with ground water source. Drinking water from centralized water supply system was supplied to 58.24% of total population. The qualified rate of water samples was 26.39% for total 288 water samples, 35.38% for surface water samples and 18.99% for ground water samples respectively. The hygienic state of surface water was much better （P〈0.01）. Conclusion In some rural areas in Fujian Province,drinking water quality is not good, microbial contamination is serious.
