目的了解集宁区农村生活饮用水卫生状况。方法采集集宁区28个自然村集中式供水井水样,按照GB/T5750-2006《生活饮用水卫生标准检验方法》中的“农村小型集中式供水和分散式供水部分水质指标及限值”进行检测。结果采集水样112份,合格率73.2%。不合格指标主要有细菌总数,氟化物,总硬度、耗氧量。丰水期所采集水样合格率为82.1%(46/56),枯水期为64.3%(36/56)差异有显著性(P<0.05);出厂水的合格率为78.6%(44/56),末梢水的合格率为67.9%(38/56),差异无显著性(P>0.05)。结论集宁区农村生活饮用水水质合格率比较高,但微生物污染较重,应加强水质净化消毒工作。
Objective To understand the health status of rural drinking water in Jining District. Methods The water samples collected from 28 water supply wells in 28 natural villages in Jining were collected. According to GB / T5750-2006 Standard Test Method for Drinking Water Quality Standard of Rural Small Centralized Water Supply and Dispersal Water Supply, "For testing. Results 112 water samples were collected with a pass rate of 73.2%. The main failure indicators are the total number of bacteria, fluoride, total hardness, oxygen consumption. The qualified rate of water samples collected during the wet season was 82.1% (46/56), and the dry season was 64.3% (36/56) (P <0.05). The passing rate of factory water was 78.6% (44/56) , The qualified rate of peripheral water was 67.9% (38/56), the difference was not significant (P> 0.05). Conclusion The qualified rate of drinking water in rural areas in Jining District is relatively high, but the microbial contamination is heavy. Therefore, water quality disinfection should be strengthened.
