广州市天河区2007～2008年游泳池水水质卫生监测分析

Test result analysis of swimming pool sanitary service and water quality in Tianhe during 2007～2008

目的：了解广州市天河区游泳池的水质卫生状况,保障游泳者的身体健康,为加强游泳池的卫生管理提供科学依据。方法：对天河区游泳池水水质进行检验,并对2007-2008年检测结果进行统计分析。结果：2007-2008年游泳池水合格率较高的分别是浑浊度100.0%、100.0%;pH值97.3%、97.6%;尿素93.2%、97.6%;大肠菌群90.5%、90.2%;其次是细菌总数,合格率为78.4%、87.8%;游离性余氯合格率最低,为37.8%、30.5%。两年水样总体合格率和不同类型游泳池水质合格率均无显著性差异。结论：天河区游泳池水水质卫生状况恶劣,仍要强化游泳池水的消毒工作,尤其应加强对游离性余氯的监督监测。同时须注意定期换水并防止池水受到粪便污染。

Objective：To explore the sanitary quality of swimming pool water of Tianhe District of Guangzhou to ensure the body healthy of swimmers, prevent the breakout of infectious diseases and provide the scientific evidence for hygienic control. Methods：We tedest the hygienic indices of swimming water in Tianhe and analyzed the results from 2007 to 2008. Results ：There was no obvious difference in the sanitary quality of swimming pool water from 2007 to 2008. However, the total qualified rate was very low, since the dissociate chlorine qualified rate was very low. Among the different type＇s swimming pools, the qualified rates had no obvious difference. Conclusion：The sanitary quality of swimming pool water in Tianhe is very poor. We should strengthen the disinfectant work in swimming pools, especially pay much attention to detect and supervise the dissociate chlorine. At the same time, we should advice relevant units to change the water and prevent contamination from excrements.
