目的了解宝鸡市农村饮水安全工程水质卫生状况及存在问题。方法选取宝鸡市10个县区225个农村饮水安全工程,对其水质进行监测评价。结果采集枯水期、丰水期出厂水及末梢水共900份水样进行检测,总合格率为74.44%,枯水期水质合格率为77.78%,丰水期水质合格率为69.34%,两者差异有统计学意义;出厂水合格率为76.22%,末梢水合格率为72.67%,两者差异无统计学意义;不同水源类型,深井水、浅井水、泉水、江河水、溪水合格率分别为85.53%、62.07%、60.47%、57.69%和65.00%,差异有统计学意义;水净化处理情况,完全处理水质合格率为86.21%,不完全处理及未处理水质合格率为72.70%,两者差异有统计学意义。结论结论宝鸡市农村饮水安全工程水源防护较差,多数工程点未进行水净化消毒处理,微生物污染较重。要增强对农村饮水安全工程的投入,配备水净化消毒设施,加强水源保护,加强供水管理和对农村饮水安全工程供水的监督管理,提高农村饮水安全工程供水质量,确保农村居民饮用安全饮水。
Objective To understand the sanitary status and existing problems of water quality in rural drinking water safety project in Baoji City. Methods 225 rural drinking water safety projects in 10 counties and districts of Baoji city were selected to monitor and evaluate their water quality. Results A total of 900 water samples were collected from the factory water and the terminal water in the dry season and the wet season. The total qualified rate was 74.44%, the qualified rate of water quality in dry season was 77.78% and the qualified rate of water quality in wet season was 69.34% The passing rate of factory water was 76.22%, and the qualified rate of peripheral water was 72.67%. There was no significant difference between the two types of water quality. The pass rates of deep well water, shallow well water, spring water, river water and stream water were 85.53% 62.07%, 60.47%, 57.69% and 65.00%, respectively. The difference was statistically significant. In the water purification treatment, the qualified rate of completely treated water was 86.21%, and the pass rate of incompletely treated and untreated water was 72.70% Significance of learning. Conclusions Conclusion The water source protection of rural drinking water safety project in Baoji City is poor. Most projects do not carry out water purification and disinfection treatment, and microbial contamination is heavy. To increase investment in rural drinking water safety projects, equipped with water purification and disinfection facilities, strengthen water protection, strengthen water supply management and water supply in rural drinking water safety supervision and management, improve water quality in rural drinking water safety projects to ensure that rural residents drinking safe drinking water.
