目的了解东莞市人工游泳池水质的卫生状况。方法对东莞市131家持卫生许可证的游泳场所进行采样检测,按照《游泳场所卫生标准》GB9667-1996进行评价,利用SPSS统计软件包进行分析。结果 131家人工游泳池合格35家,合格率为26.72%;共检测262份泳池水,各项指标均合格的有86份,合格率为32.82%。单项指标中,浑浊度、尿素、游离余氯、细菌总数、大肠菌群和PH值的合格率依次为100%、54.96%、82.06%、86.64%、98.09%和96.56%。经Bivariate分析,游泳池水样尿素浓度与细菌总数存在线性相关(r=0.556,p<0.01)。结论东莞市人工游泳池合格率低,尿素、游离余氯及细菌总数的合格率比较低。
Objective To understand the health status of artificial swimming pool in Dongguan City. Methods The samples of 131 swimming pools with health permits were collected and tested in Dongguan City. The swimming pools were evaluated according to GB9667-1996, and SPSS statistical package was used for analysis. Results A total of 351 qualified swimming pools were qualified, with a pass rate of 26.72%. A total of 262 pool water samples were tested, of which 86 were qualified. The pass rate was 32.82%. The qualified rate of turbidity, urea, free residual chlorine, total bacteria, coliform bacteria and PH value were 100%, 54.96%, 82.06%, 86.64%, 98.09% and 96.56% in single index. According to Bivariate analysis, there was a linear correlation between swimming pool water sample urea concentration and the total number of bacteria (r = 0.556, p <0.01). Conclusion The passing rate of artificial swimming pool in Dongguan City is low, and the passing rate of urea, free residual chlorine and total bacteria is relatively low.
