目的对滦县学校供水卫生状况进行调查和水质检验,为提高饮水卫生质量、保障师生身体健康提供科学依据。方法编制学校供水卫生状况调查表,对学校供水情况逐一进行调查,并采集学校生活饮用水样品进行检验分析。结果滦县共有各类学校133所,集中式供水学校占72.93%(97/133);学校供水水源均为地下水,深层地下水水源占79.70%(106/133);学校饮水消毒实施率仅为8.27%(11/133);水源防护总体合格率为71.43%(95/133),集中供水水源防护合格率为78.53%(76/97),分散式供水防护合格率为52.78%(19/36),不同供水方式水源防护合格率有统计学差异(χ~2=8.40,P<0.01);水质样品检验总体合格率为78.95%(105/133),城区集中供水、学校自建集中供水、村建集中供水、分散式供水水质检验合格率分别为100%(11/11)、77.61%(52/67)、78.94%(15/19)、75.00%(27/36),不同供水类型水质合格率无统计学差异(χ~2=3.35,P>0.05);检验指标中感官指标合格率最高为100%(133/133),微生物指标合格率最低,为81.95%(109/133),不同检验指标合格率有统计差异(χ~2=26.33,P<0.01)。结论滦县学校饮用水污染的主要因素为微生物污染,饮水消毒实施率低、水源防护不合格是造成饮水污染的主要原因,因此应加强水质消毒和水源防护,减少水质污染,提高学校饮水卫生质量。 Objective To investigate the status of water supply and sanitation of schools in Luanxian County and provide a scientific basis for improving the hygiene quality of drinking water and ensuring the health of teachers and students. Methods Prepare a questionnaire of school water supply and sanitation, investigate the situation of school water supply one by one, and collect samples of school drinking water for testing and analysis. Results There were 133 schools of various types in Luan County and 72.93% (97/133) in centralized water supply schools. The school water supply was groundwater, and the deep groundwater sources accounted for 79.70% (106/133). The school water disinfection implementation rate was only 8.27 % (11/133). The overall pass rate of water source protection was 71.43% (95/133), that of centralized water source protection was 78.53% (76/97), that of decentralized water supply protection was 52.78% (19/36) (Χ ~ 2 = 8.40, P <0.01). The overall pass rate of water quality samples was 78.95% (105/133). Urban centralized water supply, self-built centralized water supply in schools and village The qualified rate of water supply and decentralized water supply in construction was 100% (11/11), 77.61% (52/67), 78.94% (15/19) and 75.00% (27/36), respectively. The water quality of different types of water supply was qualified There was no significant difference (χ ~ 2 = 3.35, P> 0.05). The highest pass rate of sensory index in test index was 100% (133/133), the lowest passing rate of microbial index was 81.95% (109/133) The passing rate of test indicators were statistically different (χ ~ 2 = 26.33, P <0.01). Conclusions The main factors of drinking water pollution in schools in Luanxian County are microbial pollution, low implementation rate of drinking water disinfection and unqualified water source protection, which is the main reason of drinking water pollution. Therefore, water quality disinfection and water source protection should be strengthened to reduce water pollution and improve school drinking water hygienic quality .
