2012—2015年北京市海淀区游泳场所水质卫生状况

Sanitary status of swimming pool water quality in Haidian District of Beijing from 2012-2015

目的了解北京市海淀区游泳池水质卫生状况,为卫生监管部门提供科学的管理依据,保障游泳者身体健康。方法于2012—2015年夏季对所监测北京市海淀区辖区内游泳场馆采集3件泳池水样品,分别检测pH值、浑浊度、尿素、细菌总数、大肠菌群、游离性余氯6项指标,并对结果进行分析。结果连续4年北京市海淀区游泳池水质整体合情况相对稳定,合格率差异无统计学意义(χ~2=5.21,P>0.05);各项卫生学指标中,浑浊度和大肠菌群的合格率最高(99.6%,99.9%),尿素的合格率最低(86.2%)。4类游泳场馆中,社区内游泳池水质合格率最低(62.6%),学校附属泳池水质合格率最高(85.1%)。4类游泳场馆泳池水卫生学指标中,pH值、尿素、游离性余氯合格率最低的均是社区内游泳池(94.1%、75.9%和88.9%)。结论北京市海淀区游泳场馆泳池水卫生状况有待进一步改善,应加强对游泳场馆的卫生监督与指导工作。

[Objective]To understand the sanitary status of swimming pool water quality in Haidian District of Beijing,provide scientific management basis for health supervision department and protect the health of swimmers.[Methods]3 water samples of pool were respectively collected from each swimming pool in Haidian District of Beijing in the summer of 2012-2015,to detect 6 indicators（including pH value,turbidity,urea,total bacteria,coliform,free residual chlorine）,and the results are analyzed.[Results]The sanitary status of swimming pool water quality in 4 consecutive years was relatively stable,and there was not statistically significant difference in the annual qualified rate（χ^2 =5.21,P〉0.05）. In the indicators,the qualified rate of the turbidity and coliform bacteria were both the highest（99.6% and 99.9%）,and the qualified rate of urea was the lowest（86.2%）.In 4 types of swimming places,the qualified rate of water quality in community swimming pools was the lowest（62.6%）,and that in school swimming pools was the highest（85.1%）. For the hygiene indicators in 4 types of swimming places,community swimming pools had the lowest qualified rates of pH value,urea and free residual chlorine（94.1%,75.9% and 88.9%）.[Conclusion]The sanitary status of swimming pool water quality needs to be improved further in Haidian District of Beijing,while the supervision and guidance of the swimming places should be strengthened.
