[目的]了解日照市农村学校生活饮用水卫生状况,探讨农村学校饮用水卫生管理措施。[方法]以该市全部农村学校为调查对象,进行丰水期和枯水期水质常规监测。2013年随机抽取全市农村学校总数的1/3进行水质卫生监测,2014年在2013年剩余未监测农村学校中按1/2比例随机抽取农村学校进行饮用水监测,2015年对前两年剩余未监测的农村学校进行饮用水监测。[结果]使用消毒措施的农村学校占本市农村学校总数的30.77%;192份使用消毒处理措施的水样合格率为90.10%,432份未使用消毒处理措施的水样合格率为53.01%,差别具有统计学意义(χ2=30.40,P<0.05);消毒剂指标检测合格的水样中其微生物指标合格率为98.33%,消毒剂指标检测不合格的水样中其微生物指标检测合格率为25%,差别具有统计学意义(χ2=91.12,P<0.05)。[结论]该市农村学校饮用水存在的主要问题是配备使用消毒处理措施的供水工程比例偏低,未使用消毒处理措施的农村学校饮用水水质合格率偏低,农村学校供水工程消毒处理方式需进一步完善,以保证学生的饮水健康。
[Objective] To understand the sanitary status of drinking water in rural schools in Rizhao City and explore the sanitary management measures of drinking water in rural schools. [Method] Taking all the rural schools in the city as the survey object, routine monitoring of water quality in wet season and dry season was conducted. In 2013, one-third of the total rural schools in the city were randomly selected for water quality and hygiene monitoring. In 2014, rural schools were randomly selected for drinking water monitoring according to the proportion of 1/2 in the remaining unmonitored rural schools in 2013, and the remaining for 2015 Monitoring of rural schools for drinking water monitoring. [Results] Rural schools using disinfection measures accounted for 30.77% of the total number of schools in rural areas of the city. The passing rate of 192 water samples with disinfection measures was 90.10%. The pass rate of 432 water samples without using disinfection measures was 53.01% The difference was statistically significant (χ2 = 30.40, P <0.05). The pass rate of microbial indicators in water samples with disinfectant index test was 98.33%, and the pass rate of microorganism test in water samples with unqualified disinfectant index was 25%, the difference was statistically significant (χ2 = 91.12, P <0.05). [Conclusion] The main problems of drinking water in rural schools in this city are that the proportion of water supply projects equipped with disinfection measures is low, the passing rate of drinking water quality of rural schools without disinfection measures is low, and the disinfection of rural school water supply projects is required To further improve in order to ensure the health of students drinking water.
