目的:了解三峡库区腹地万州区农村居民安全集中供水工程卫生现状。方法:于2013年对万州区40家农村居民安全集中供水工程开展卫生学调查,对其水质进行抽样检验和评价。结果:按要求使用消毒设备的占40%,水样合格率37.50%,枯水期水质合格率25%低于丰水期的50%,两者差异有统计意义(P<0.01)。结论:三峡库区腹地万州区农村居民安全集中供水工程水质合格率较低,供水存在不安全因素,消毒措施亟待落实。
Objective: To understand the status quo of sanitary centralized water supply for rural residents in Wanzhou District, the hinterland of the Three Gorges Reservoir. Methods: In 2013, 40 rural residents in Wanzhou District conducted a centralized health survey on their hygiene and carried out a sample survey and evaluation of their water quality. Results: 40% disinfection equipment was required, the pass rate of water sample was 37.50%, the pass rate of water quality in dry season was 25% lower than 50% of wet season, the difference was statistically significant (P <0.01). Conclusion: The qualified rate of water quality of rural residents in Wanzhou District in the hinterland of Three Gorges Reservoir Area is relatively low. There are insecurity factors in water supply and the disinfection measures need to be implemented urgently.
