2018—2019年海口市游泳池水质卫生监测分析

Analysis on the Sanitary Monitoring of Swimming Pool Water Quality in Haikou City from 2018 to 2019

目的了解海口市游泳池水质卫生状况,为游泳池水质监管提供理论依据。方法采用随机抽样和定期跟踪检测游泳池水样2160份,依据《公共场所卫生指标及限值要求》(GB 37488-2019)对游泳池水质各项参数指标进行评价。结果海口市游泳池水质浑浊度、大肠杆菌、细菌总数、pH值、尿素、游泳池水游离性余氯等6项参数指标的合格率分别为:96.02%、93.73%、92.81%、91.82%、85.34%、51.34%;游泳池水质卫生总体6项指标合格率为34%;游泳池水质检测专业技术人才短缺;水质检测成本较高,检测结果时间周期较长,游泳池水质卫生状况差异性较大。结论按照《公共场所卫生指标及限值要求》(GB 37488-2019)标准评价,海口市游泳池水质参数部分指标合格率较低。建议应加强水质管理人员培训,提高游泳池水质检查员的技术水平,强化水质检测指标的真实性和有效性;采用游泳池水质智能化管理,可以减少水质检测的人力、物力和财力;利用计算机自动控制,实时监控水质动态指标,采用预警、报警、自动精准施药、自动注水、自动过滤等程序形成自动化监测控制系统,保障游泳池水质维持在安全标准范围值内,有效解决水质安全问题。

Objective To understand the sanitary condition of swimming pools in Haikou City and provide theoretical basis for water quality supervision of swimming pools.Methods 2,160 samples of swimming pool water were randomly sampled and regularly tracked,and various parameters of swimming pool water quality were evaluated according to the Requirements of Public Health Indicators and Limits(GB 37488-2019).Results The qualified rates of turbidity,Escherichia coli,total number of bacteria,pH value,urea and free residual chlorine in swimming pool in Haikou city were 96.02%,93.73%,92.81%,91.82%,85.34%and 51.34%,respectively.The pass rate of the 6 indexes of the swimming pool water quality hygiene was 34%.There was shortage of professional technical personnel for water quality testing in swimming pools;the cost of water quality testing was high,the time period of testing results was long,and the health status of water quality in swimming pools was quite different.Conclusion According to the standard of Public Health Indicators and Limits(GB 37488-2019),the qualified rate of some water quality parameters of swimming pools in Haikou city was low.Suggestions Strengthen the training of water quality management personnel,improve the technical level of swimming pool water quality inspectors,strengthen the authenticity and effectiveness of water quality testing indicators,and adopting intelligent management of swimming pool water quality could reduce manpower,material resources and financial resources for water quality detection.Using computer automatic control,real-time monitoring of water quality dynamic indicators,using early warning,alarm,automatic precision application,automatic water injection,automatic filtering and other procedures to form an automatic monitoring and control system,to ensure that the water quality of the swimming pool was maintained in the range of safety standards,could effectively solve the water quality safety problems.
