Survey on Sanitary Quality of Swimming Pool Water of Public Places

目的 了解江阴市游泳场所水质卫生状况。方法 对全市7家游泳场所的水质和卫生设施进行监测和调查。结果 游泳池水pH值、浑浊度、尿素均符合卫生要求,合格率分别为93.9％、98.5％和98.5％。水温和余氯合格率较低（3.0％和19.7％）。浑浊度和尿素浓度与开业时间呈正相关（P<0.05）;室内游泳池水浑浊度显著低于室外,细菌总数和大肠菌群显著高于室外（P<0.05）。结论 江阴市游泳场所池水卫生消毒仍需强化。

ve To explore the sanitary quality of swimming pool water of public places. Methods The sanitary quality of swimming pool water of 7 public places was monitored, and the sanitory facilities equiped in swim-ming pools were investigated in Jiangyin. Results The pH values, the levels of turbidity and urea in swimming pool water all accorded with the related sanitary standards, and their related qualified rates were 93.9% , 98.5% and 98.5% respectively. For water temperature and residual chlorine, the qualified rates were lower, 3.0% and 19.7% respectively. Both the levels of turbidity and urea were positively correlated with the openning durations of swimming pools (P<0.05). The significantly lower levels of turbidity and significantly higher levels of the total count of bac-teria and the coliform group number appeared in indoor swimming pool water compared with those of outdoor swim-ming pool water respectively(P < 0.05). Conclusion The sanitary disinfection of swimming pool water still required to be strengthened more.
