目的了解2004～2007年厦门市游泳池水质状况及变化趋势,为进一步提高卫生质量提供背景资料。方法按照GB/T18204-2000《公共场所卫生标准检验方法》对655份泳池水进行细菌总数、大肠菌群、浑浊度、色度、pH值、游离性余氯、尿素等的含量测定、评价。结果游泳池水质总合格率为49.01%,2004-2007年合格率分别为36.52%、45.85%、51.15%、和74.49%。经卡方检验(X~2=37.40,P<0.01)有统计学意义,显示游泳池水质呈逐年好转的趋势。水质检测项目中,游离性余氯合格率最低,仅为65.95%。结论我市游泳池水质卫生状况虽然逐年趋好,但依然不容乐观,卫生监督部门应加强卫生监督管理,提高水质卫生质量,保障游泳者身体健康。
Objective To understand the status and trend of swimming pool water quality in Xiamen City from 2004 to 2007 and provide background information for further improving the quality of health care. Methods The total bacterial count, coliform bacteria, turbidity, chroma, pH value, free residual chlorine, urea and other contents of 655 swimming pool water were determined and evaluated in accordance with GB / T18204-2000 “Public places hygiene standard test method”. Results The total qualified rate of swimming pool water quality was 49.01%, and the passing rates in 2004-2007 were 36.52%, 45.85%, 51.15% and 74.49% respectively. The chi-square test (X ~ 2 = 37.40, P <0.01) was statistically significant, showing a trend of swimming pool water quality improved year by year. In the water quality testing project, the free residual chlorine pass rate is the lowest, only 65.95%. Conclusion Although the quality of swimming pool water quality in our city is getting better year by year, it is still not optimistic. The health supervision departments should strengthen the hygiene supervision and management, improve the quality of water quality and hygiene, and ensure the physical health of swimmers.
