目的了解句容市游泳池水质状况。方法采集游泳池水样,依据《游泳场所卫生标准》(GB9667-1996)进行检测评价。结果游泳池水质合格率为22.2%,2009年合格率为20.0%,2010年为4.3%,2011年为31.8%,2012年为32.7%,4年合格率差异有统计学意义(χ2=14.321,P<0.05);指标合格率由高到低依次为浑浊度(100%)、pH值(95.0%)、大肠菌群(87.8%)、细菌总数(71.1%)、游离余氯(58.9%)、尿素(26.1%),差异有统计学意义(χ2=351.22,P<0.01);儿童池合格率小于成人池,差异有统计学意义(χ2=8.56,P<0.05)。结论句容市游泳池水质卫生情况总体较差,应加强监督监测工作。
Objective To understand the water quality of swimming pool in Jurong City. Methods The swimming pool water samples were collected and tested in accordance with the hygiene standards of swimming places (GB9667-1996). Results The qualified rate of swimming pool water quality was 22.2%. The passing rate in 2009 was 20.0%, 4.3% in 2010, 31.8% in 2011 and 32.7% in 2012, the difference of 4-year pass rate was statistically significant (χ2 = 14.321, P <0.05). The passing rate of indicators from high to low were turbidity (100%), pH value (95.0%), coliform bacteria (87.8%), total bacteria (71.1%), free residual chlorine The difference was statistically significant (χ2 = 8.52, P <0.01). The pass rate of children’s pool was less than that of adult’s pool (χ2 = 8.56, P <0.05). Conclusion The general situation of water quality and sanitation of swimming pool in Jurong City is generally poor. Supervision and monitoring work should be strengthened.
