摘要
目的了解十堰市农村生活饮用水卫生现状。方法对十堰市3城区共37个农村供水点[地表水34个(全部为集中式供水),地下水8个(集中式供水6个,分散式供水2个)]水质进行了监测,根据《农村实施(生活饮用水卫生标准)准则》进行评价。结果集中式供水人口占全市农村总人口的99.87%,分散式供水人口约占全市农村人口的0.13%。在采样监测的74份水样中,细菌学指标均合格的样品有54份,合格率72.97%;感官性状指标合格71份,合格率95.95%;一般化学指标合格46份,合格率62.16%;毒理学指标合格71份,合格率95.95%。结论该市农村饮用水主要卫生问题是饮用水被微生物污染,同时还存在着硝酸盐超标的情况。
[Objective]To understand the sanitary situation of drinking water in rural areas of Shiyan City. [Methods]The sanitary qualities of water samples collected from 37 sampling locations,including 34 surface water locations(all were centralized water supply locations) and 8 underground water locations(6 centralized water supply locations,2 decentralized water supply locations),in 3 districts of Shiyan City were monitored,and were assessed according to the "Criteria of Sanitary Standard for Drinking Water Enforced in Rural Areas". [Results]The populations of centralized water supply was 99.87 % of the total populations of rural areas of Shiyan City,whereas,the population of decentralized water was only accounted for 0.13 %.Among the 74 water samples for monitoring,the samples of total qualified for the bacterial indexes were 54,the qualified rate of 70.27%;The qualified rates of the sensory organ index,general chemistry index,and toxicology index were 95.95%(71),62.16%(46),95.95 %(71) respectively. [Conclusion]The main sanitary problem of drinking water in rural area of Shiyan City is that the drinking water was polluted by microbe,simultaneously,there exists nitrate nitrogen over standard.
