目的了解三明市区游泳池水的卫生状况,指导卫生监管工作,保障游泳者身体健康。方法依据GB 9667-1996《游泳场所卫生标准》,对2009—2011年市区的主要游泳场所水质进行监测,并对结果分析评价。结果 2009—2011年三明市游泳池水卫生质量合格率平均47.2%,3年分别为37.5%、51.8%和55.9%,3年间有逐渐提高趋势。各项指标中,浑浊度总合格率为100%,pH值、尿素、细菌总数总合格率在90.0%以上,游离性余氯合格率最低为56.9%。余氯浓度越高,微生物指标合格率也越高。结论三明市游泳池水合格率较低,尤其是游离性余氯合格率较低,应加大卫生监管力度,规范经营行为,确保水质卫生安全。
Objective To understand the sanitary conditions of swimming pool water in Sanming City, to guide the health supervision and ensure the health of swimmers. Methods According to GB 9667-1996 Sanitary Standard for Swimming Pool, the water quality of the main swimming places in urban areas from 2009 to 2011 was monitored, and the results were analyzed and evaluated. Results In 2009-2011, the passing rate of sanitation swimming pool water quality was 47.2% on average, 37.5%, 51.8% and 55.9% respectively in 3 years, and gradually increased in 3 years. In all the indexes, the total qualified rate of turbidity was 100%. The total qualified rate of pH, urea and bacteria was above 90.0%, and the lowest qualified rate of free residual chlorine was 56.9%. The higher the residual chlorine concentration, the higher the pass rate of microbial indicators. Conclusion The passing rate of swimming pool water in Sanming City is relatively low, especially the pass rate of free residual chlorine is relatively low. Health supervision should be intensified to regulate the operation and ensure the hygiene and safety of water quality.
