2023-2024年北京市海淀区游泳场所水质卫生指标分析

Objective To analyze the results of active monitoring of the water sanitation in swimming places in Haidian District, Beijing in order to find out the existing problems, so as to provide a strong basis for strengthening control measures. Methods The water quality of normally operating swimming places in Haidian District of Beijing was monitored from 2023 to 2024. The detection indexes were pH of swimming pool water, turbidity, urea, free residual chlorine, coliform bacteria, total bacteria and residual chlorine in foot bath water. Results From 2023 to 2024, a total of 231 swimming places were monitored, and the overall qualified rate was 78.79%. The qualified rate of swimming places was similar in the two years with no statistically significant difference(P>0.05). The unqualified indexes were pH, urea, free residual chlorine in swimming pool water and residual chlorine in soaking foot pool water, and the qualified rates were 99.43%, 91.13%, 90.99% and 87.83% respectively. There was no significant difference in the difference qualified rate of the above indicators in the two years(P>0.05). The monitoring data from 2023 to 2024 showed that there were significant differences in the comprehensive health standards among the three types of swimming places(hotel and hotel affiliated facilities, school affiliated facilities, entertainment and fitness places) in Haidian District, Beijing(P<0.05). However, the qualified rates of urea content, free residual chlorine concentration in swimming pool water and residual chlorine concentration in foot soaking pool water were statistically different among different types of places(P<0.05), and the qualified rate of entertainment and fitness places on these three items was at the lowest level. Conclusion Based on the monitoring results from 2023 to 2024, future management of swimming places in Haidian District should focus on the four unqualified indicators of pH, urea, free residual chlorine in swimming pool water and residual chlorine in foot soaking pool water, and continue to strengthen daily supervision, water quality monitoring, publicity and education and operation guidance for operators.
