摘要
目的了解2018-2020年北京市密云区游泳场所游泳池水的水质卫生状况,为游泳场所监督管理提供依据。方法对密云区游泳场所游泳池水进行水质监测分析,检测项目包括大肠菌群、浑浊度、pH值、游离余氯、细菌总数、尿素、温度。结果2018-2020年共监测游泳池水251件,合格199件,总合格率为79.3%,其中,2020年合格率最低,为60.8%;三年游泳池水质合格率差异有统计学意义(χ^(2)=16.756,P<0.01);游泳池水水质检测合格率排序依次为大肠菌群(100%)、浑浊度(100%)、pH值(98.3%)、游离余氯(93.0%)、细菌总数(92.7%)、尿素(91.8%)、池水温度(70.8%)。结论2020年游泳池水合格率明显低于2018年和2019年,在新型冠状病毒肺炎疫情防控常态下,应加强游泳场所水质监督和管理。
Objective To understand the water quality of swimming places in Miyun district of Beijing from 2018 to 2020,and to provide basis for supervision and management of swimming places.Methods The water quality of swimming places in Miyun district was monitored and analyzed,including the items of coliform group,turbidity,pH value,free residual chlorine,total bacteria,urea and temperature.Results From 2018 to 2020,251 swimming pools were monitored,199 of them were qualified,and the total qualified rate was 79.3% with the lowest rate of 60.8%in 2020.The difference of qualified rate of swimming pools in three years was statistically significant(χ^(2)=16.756,P<0.01);The qualified rate sequence of monitoring items was coliform group(100%)and turbidity(100%),pH value(98.3%),free residual chlorine(93.0%),total bacteria(92.7%),urea(91.8%)and water temperature(70.8%).Conclusions The qualified rate of swimming pool water in 2020 is significantly lower than that in 2018 and 2019.The supervision and management of water quality in swimming places should be strengthened under the background of normalized COVID-19 prevention and control.
