2015-2020年常州市游泳池水余氯检测结果分析

Analysis of residual chlorine detection results of swimming pool water in Changzhou City 2015 to 2020

目的 了解常州市游泳池水余氯的卫生状况,为卫生监管提供参考依据(本文中余氯指游离性余氯和化合性余氯)。方法 2015—2020年随机抽取常州市游泳池水,用池边快检的方法检测游泳池水中的游离性余氯和化合性余氯含量,并进行分析。结果 共检测游泳池水236份,游离性余氯和化合性余氯的合格率分别为38.14%和79.66%,各年份游离性余氯和化合性余氯合格率差异无统计学意义(χ^(2)=0.586,χ^(2)=0.541,P>0.05)。不同场馆类型游泳池水化合性余氯合格率比较,差异有统计学意义(χ^(2)=30.544,P<0.01),健身馆游泳池水合格率最低。不同季节类型游泳池水游离性余氯合格率比较,差异有统计学意义(χ^(2)=18.594,P<0.01),冬春季游泳池水合格率低。结论 常州市游泳池水游离性余氯的合格率较低,冬春季节合格率更低,健身馆游泳池水的化合性余氯合格率明显低于其他场馆类型,应加强卫生监管。

Objective To understand the hygienic status of residual chlorine in swimming pool water in Changzhou and to provide reference basis for hygienic supervision (residual chlorine in this paper refers to free residual chlorine and combined residual chlorine).Methods From 2015 to2020,Changzhou swimming pool water was randomly selected,and the contents of free residua chlorine and combined residual chlorine in swimming pool water were detected and analyzed by poolside rapid detection method.Results Totally 236 samples of swimming pool water were detected.The qualified rates of free residual chlorine and combined residual chlorine were 38.14%and 79.66% respectively.There was no statistically significant difference in the qualified rates of free residual chlorine and combined residual chlorine in each year (χ^(2)=0.586 and χ^(2)=0.541,P>0.05).There was statistically significant difference in the qualified rate of combined residua chlorine in swimming pools of different venues (χ^(2)=30.544,P<0.01),the qualified rate of swimming pool water in fitness center was the lowest.There was statistically significant difference in the qualified rate of free residual chlorine in swimming pool water in different seasons (χ^(2)=18.594,P<0.01),and the qualified rate of swimming pool water in winter and spring was low.Conclusions The qualified rate of free residual chlorine in swimming pool water in Changzhou city is low,and the qualified rate is lower in winter and spring.The qualified rate of combined residual chlorine in swimming pool water in fitness centers is significantly lower than that in other venues,so health supervision should be strengthened.
