目的了解德州市游泳池水卫生质量,为监督管理游泳池水质提供依据,保障游泳者的身体健康。方法按照GB/T 17220-1998《公共场所卫生监测技术规范》采集游泳池水样品,对样品pH、浑浊度、尿素、游离性余氯、菌落总数和大肠菌群进行检验,并对检验结果进行分析。结果 2013~2014德州市游泳池水采样份数分别为56份和90份,检测合格23份和34份,合格率分别为41.07%和37.78%。总合格水样57份,总合格率为39.04%。两年水样合格率差异无统计学意义(P>0.05)。2013年和2014年检测指标中浑浊度、尿素、pH值合格率均为100%。超标项目主要为游离余氯(48.21%、43.33%)、细菌总数(78.57%、73.33%)大肠菌群(89.28%、77.78%),与2013年相比,2014年各检测指标差异无统计学意义(P>0.05)。结论德州市游泳池水水质卫生质量较差,池水的消毒工作不够规范。
Objective To understand the water quality of swimming pool in Dezhou and to provide basis for the supervision and management of swimming pool water quality and to ensure the health of swimmers. Methods According to GB / T 17220-1998 Public Health Sanitation Monitoring Technical Specifications, samples of swimming pool water were collected to test sample pH, turbidity, urea, free residual chlorine, total number of colonies and coliform bacteria, and the test results were analyzed . Results From 2013 to 2014, the samples of swimming pool water in Dezhou City were 56 samples and 90 samples, respectively. There were 23 samples and 34 samples were tested, the pass rates were 41.07% and 37.78% respectively. The total qualified water samples 57, the total pass rate of 39.04%. There was no significant difference in passing rate of water samples in two years (P> 0.05). The indicators of turbidity, urea and pH in 2013 and 2014 were all 100% qualified. Coliform bacteria (89.28%, 77.78%) of free residual chlorine (48.21%, 43.33%) and total bacteria (78.57%, 73.33%) were the main items that exceeded the standard. Compared with 2013, there was no significant difference between the detection indexes in 2014 Significance (P> 0.05). Conclusion The water quality of the swimming pool in Dezhou is poor, and the disinfection of the water is not standardized enough.
