目的了解甘肃省嘉峪关市游泳池的水质卫生状况及其影响因素,为加强游泳池卫生管理提供科学依据。方法对2013—2015年嘉峪关市所有对外开放的学校泳池、酒店泳池、住宅小区泳池和公共泳池随机采样1 270份检测并分析水质状况。结果共检测水样1 270份,合格率80.6%,且呈逐年上升趋势;3年间p H值、浑浊度、细菌总数和大肠菌群合格率分别为99.8%、99.8%、96.4%和97.6%,游离性余氯(80.8%)和尿素(66.9%)的合格率最低;3年间学校泳池(94.7%)、酒店泳池(79.1%)、住宅小区泳池(91.1%)和公共泳池(62.3%)水质合格率差异有统计学意义(χ~2=11.314,P<0.05);3年间一至四季度游泳池水质合格率差异亦有统计学意义(χ~2=13.411,P<0.05);全换式游泳池(64.5%)和循环式游泳池(88.0%)水质合格率差异有统计学意义(χ~2=11.000,P<0.05)。结论嘉峪关市游泳池水质卫生状况存在一定的安全隐患,应进一步加强游泳场所的卫生监督,以及对公众的卫生知识及公德宣传教育。
Objective To understand the sanitary status and influencing factors of the swimming pool in Jiayuguan City, Gansu Province, and to provide a scientific basis for strengthening the health management of the swimming pool. Methods A total of 1,270 samples of school swimming pool, hotel swimming pool, residential quarter swimming pool and public swimming pool in Jiayuguan City were randomly sampled from 2013 to 2015 to detect and analyze water quality. Results A total of 1 270 water samples were tested with a pass rate of 80.6%. The p H value, turbidity, total bacteria and coliform bacteria pass rates were 99.8%, 99.8%, 96.4% and 97.6% respectively in three years, (94.7%), hotel swimming pool (79.1%), residential area swimming pool (91.1%) and public swimming pool (62.3%) in the three years, with the lowest pass rate of free residual chlorine (80.8%) and urea The qualified rate of water quality was statistically significant (χ ~ 2 = 11.314, P <0.05). There was also a statistically significant difference between the first four quarters and the fourth quarter (χ ~ 2 = 13.411, P <0.05) The qualified rate of water quality in swimming pool (64.5%) and circulating swimming pool (88.0%) was statistically significant (χ ~ 2 = 11.000, P <0.05). Conclusion There is a potential safety hazard in the swimming pool water quality and sanitary conditions in Jiayuguan City. Health supervision of swimming pools should be further strengthened as well as education of public health knowledge and public morality.
