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。方法按照《公共场所卫生监测技术规范》(GB/T 7220-1998)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 2010年度共采集水样147份,合格份数为94份,总合格率为63.9%。2011年度共采集水样163份,合格份数为114份,总合格率为69.9%。两年水样总体合格率差异无统计学意义(P>0.05)。2010和2011年游泳池水游离性余氯合格率最低(70.9%、71.7%),其次是细菌总数(89.1%、92.0%);合格率较高的分别是尿素(96.6%、96.3%)、大肠菌群(100%、98.8%)、浑浊度(100%、100%)。结论大连市游泳池水的卫生状况不容乐观,应加强游泳场所的监管力度,强化消毒措施。
Objective To understand the sanitary condition 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 Pool water samples were randomly collected according to “Technical Specifications for Sanitation Monitoring in Public Places” (GB / T 7220-1998), 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 147 water samples were collected in 2010, 94 of which were qualified, with a total pass rate of 63.9%. In 2011, a total of 163 water samples were collected, with 114 qualified ones, with a total passing rate of 69.9%. There was no significant difference in the overall pass rate of water samples in two years (P> 0.05). The qualified rate of free residual chlorine in swimming pool water was the lowest (70.9%, 71.7%) in 2010 and 2011, followed by the total number of bacteria (89.1%, 92.0%). The higher pass rates were urea (96.6%, 96.3% Flora (100%, 98.8%), turbidity (100%, 100%). Conclusion The health status of swimming pool water in Dalian is not optimistic. The supervision of swimming places should be strengthened and disinfection measures should be strengthened.
