摘　　要：目的了解溧阳市游泳池水水质卫生状况,为加强游泳池卫生管理提供科学依据,保障人民群众的安全健康。方法采集2013年-2017年(6月-8月)溧阳市游泳池水样并进行水质检测,检测项目包括pH值、浑浊度、游离余氯、尿素、细菌总数、大肠菌群。其中游离余氯为现场检测,其余项目在实验室检测。对历年检测结果进行统计学分析。结果 2013年-2017年夏季共采集样品137份,其中合格72份,合格率为52.6%。2017年最高,合格率达到75.0%,2013年最低,合格率仅37.5%。不同年份的合格率差异具有统计学意义(χ~2=11.71 P<0.05)。pH值、浑浊度合格率均为100%,游离余氯、尿素、细菌总数、大肠菌群合格率分别为60.6%、81.0%、91.2%、97.1%。不同项目合格率差异有统计学意义(χ~2=156.82,P<0.05)。结论溧阳市游泳池水水质仍存在较大问题,不容忽视,必须进一步加强监测。Objective To understand the hygienic status of swimming pool water in Liyang,so as to provide scientific basis for the sanitation management of swimming pool and ensure the safety and health of the people. Methods The swimming pool water samples from 2013 to 2017（ June-August） were collected for water quality detection,and the test items included pH,turbidity,free residual chlorine,urea,total bacterial sum and coliform group. Free residual chlorine was analyzed on-site and the others were tested in laboratory. All the results were collected for statistic analysis. Results During 2013-2017,137 samples were collected,and 72 samples were qualified,with the qualified rate of 52. 6%. The highest qualified rate（ 75. 0%） was found in 2017,and the lowest rate was 37. 5% in 2013. The differences of qualified rates were statistically significant（ χ^2=11. 71,P 〈0. 05）. The qualified rates of pH and turbidity were 100%,and the qualified rates of free residual chlorine,urea,total bacterial sum and coliform group were 60. 6%,81. 0%,91. 2% and 97. 1%. And the differences of qualified rates among these items were statistically significant（ χ^2= 156. 82,P 〈0. 05）. Conclusion The quality of swimming pool water in Liyang is still with some problems and can not be ignored. The monitoring of pool water quality should be further strengthened.
