目的了解南京市浦口区游泳池水质卫生状况,以加强游泳场所卫生管理。方法按照有关技术规范,采集11家游泳池48份水样,检测pH值、浑浊度、尿素、游离性余氯、大肠菌群、细菌总数等6项指标,有1项不合格则判断为不合格。结果水样合格21份,合格率为43.8%,其中pH值、浑浊度、尿素、游离性余氯、大肠菌群、细菌总数6项指标,合格率分别为100.0%、95.8%、100.0%、45.8%、70.8%和95.8%,余氯合格率最低。微生物指标不达标的水样其游离余氯浓度均<0.3 mg/L。结论浦口区游泳场所水质卫生状况不容乐观,池水净化消毒工作必须规范,并应加强监督管理。
Objective To understand the sanitary conditions of swimming pool in Pukou District of Nanjing to strengthen the hygiene management of swimming pool. Methods According to the relevant technical specifications, 48 water samples from 11 swimming pools were collected and six indicators including pH value, turbidity, urea, free residual chlorine, coliform bacteria and total bacteria were detected. One of them failed to be judged as unqualified . The results showed that 21 samples were qualified and the pass rate was 43.8%. The six indexes of pH value, turbidity, urea, free residual chlorine, coliform bacteria and total bacteria were 100.0%, 95.8% and 100.0% 45.8%, 70.8% and 95.8%, with the lowest qualified rate of residual chlorine. Microbial indicators of non-compliance of the water sample free residual chlorine concentrations were <0.3 mg / L. Conclusion The water quality and sanitation of swimming pool in Pukou District is not optimistic. The purification and disinfection of pond water must be regulated and the supervision and management should be strengthened.
