目的:分析平阳县2007~2009年游泳池水质检测的不合格项,了解游泳池水质中存在的主要问题。方法:按公共场所卫生标准检验方法GB/T18204-2000进行检测,按游泳池场所卫生标准GB9667-1996进行评价。结果:2007~2009年每年检测游泳池水47份,其中细菌总数、大肠菌群、尿素、浊度和余氯的不合格率呈逐年下降趋势,pH值的不合格率却在逐年上升,且在每年的不合格项目中,占首位的指标均是余氯。经过Pearson相关分析,余氯与细菌总数、大肠菌群、尿素、浊度呈负相关。结论:游泳池水质存在两大主要问题:1.pH值偏低;2.未能及时补充合格新水。
Objective: To analyze the unqualified items of swimming pool water quality testing in Pingyang County from 2007 to 2009, and to understand the main problems in swimming pool water quality. Methods: According to public health standards test method GB / T18204-2000 for testing, according to the swimming pool health standards GB9667-1996 evaluation. Results: From 2007 to 2009, 47 samples of swimming pool water were tested every year. Including bacteria, coliforms, urea, turbidity and residual chlorine were declining year by year. The failure rate of pH value increased year by year. In the annual failed project, the top index is residual chlorine. After Pearson correlation analysis, the residual chlorine and the total number of bacteria, coliform bacteria, urea, turbidity was negatively correlated. Conclusion: There are two major problems in swimming pool water quality: 1. The value of pH is low; 2. Failure to replenish new water in time.
