目的了解大连市游泳池水水质卫生状况,加强游泳池的卫生管理,为保障游泳者的身体健康提供科学依据。方法依照《公共场所卫生监测技术规范》(GB/T 17220-1998)随机采集游泳池水样,按照《公共场所卫生标准检验方法》(GB/T 18204-2000)对游泳池水进行检验,根据《游泳场所卫生标准》(GB 9667-1996)进行水质评价。结果 2012年共采集水样93份,合格79份,总合格率为84.9%。游离性余氯合格率最低,为93.5%;其次为pH值96.8%,尿素96.8%,细菌总数为97.8%,浑浊度和大肠菌群数均为100.0%。6项指标合格率比较差异有统计学意义(χ2=11.16,P<0.05);两类游泳池水6项指标合格率比较差异无统计学意义(P>0.05)。2012年与2011年泳池水合格率比较差异有统计学意义(P<0.05)。结论大连市游泳池水的卫生状况较往年有所改善。
Objective To understand the sanitary status of swimming pool water in Dalian and to strengthen the health management of swimming pool so as to provide a scientific basis for the protection of swimmers’ health. Methods The water samples of the swimming pool were randomly collected according to the Technical Specifications for Health Monitoring in Public Places (GB / T 17220-1998), and the swimming pool water was inspected according to the “Public Health Standard Test Method” (GB / T 18204-2000) Place health standards "(GB 9667-1996) for water quality evaluation. Results A total of 93 water samples were collected in 2012, of which 79 were qualified, with a total pass rate of 84.9%. The lowest rate of free residual chlorine was 93.5%, followed by 96.8% of pH, 96.8% of urea, 97.8% of total bacteria and 100.0% of turbidity and coliform bacteria. There was significant difference in passing rate between the six indexes (χ2 = 11.16, P <0.05). There was no significant difference in passing rate among the six indexes (P> 0.05). The passing rate of swimming pool water in 2012 and 2011 was significantly different (P <0.05). Conclusion The health status of swimming pool water in Dalian has been improved over previous years.
