2013年北京市东城区游泳池水质卫生状况分析

Analysis on sanitary conditions of swimming pool water in Dongcheng District of Beijing in 2013

目的了解2013年北京市东城区游泳池水质卫生状况,为改进游泳池水质、提高卫生质量提供依据。方法 2013年5-10月及2014年1月对辖区内经营性质、酒店内部、学校和物业附属性质的3种类型的游泳馆(池)进行监测,每家游泳馆(池)每月采集水样3件,并进行检测,连续监测7个月;检测的项目包括p H值、浑浊度、尿素、游离性余氯、细菌总数和大肠菌群6项指标。结果共监测水样210件,游泳池水的总体合格率为50.5%。p H值、浑浊度、大肠菌群和细菌总数的合格率为100%,游离性余氯的合格率为83.3%,尿素的合格率为61.4%。辖区内经营性质、酒店内部、学校和物业附属性质的3种类型游泳池水质合格率不同,分别为41.3%、52.4%、71.4%,其差异有统计学意义(χ2=10.36,P<0.05)。结论北京市东城区夏季游泳池水质的卫生学指标较差,亟待改善。要加强游离性余氯及尿素的监控力度。

[Objective]To understand the water quality of swimming pools in Dongcheng District of Beijing in 2013, and provide scientific evidence for improving the water quality of swimming pools. [Methods]Three different types of swimming places, which included business, hotel internal and school affiliated swimming pools, were monitored from May-October 2013 and were monitored once on February in 2014. Three samples were collected from each swimming place monthly for continuous 7 months. The test items included pH value, turbidity, urea, free residual chlorine, total bacterial count and coliform group count. [Results]A total of 210 water samples were tested, and the total qualified rate was 50.5%. The qualified rate of pH value, turbidity, total bacterial count and coliform group count were 100%, The qualified rate of free residual chlorine was 83.3%. The qualified rate of urea was 61.4%. The qualified rate of business swimming pools, hotel internal swimming pools and school affiliated swimming pools was 41.3%, 52.4%, 71.4%, respectively, with significant difference. [Conclusion]The sanitary indicators of swimming pools are poor in Dongcheng District of Beijing City in summer, which needs improvement.
