Water quality monitoring results of swimming pool in Changzhou City in 2018-2020

目的了解江苏省常州市游泳池水质安全卫生状况,保障游泳人群身体健康,为卫生监督部门对游泳场所的卫生监管提供依据。方法依据《公共场所卫生检验方法第6部分:卫生监测技术规范》(GB/T 18204.6-2013)对2018—2020年6~8月常州市游泳池水样品进行采样和检测,分别按照《游泳场所卫生标准》(GB 9667-1996)和《公共场所卫生指标及限值要求》(GB 37488-2019)对游泳池水进行卫生学评价。应用SPSS 19.0统计软件,采用卡方检验统计分析数据。结果2018—2020年共检测游泳场所94家,采集水样178份,合格40份,合格率为22.47%,三年的水质检测合格率差异无统计学意义(χ^(2)=5.422,P=0.066)。不合格项目主要是游离性余氯(46.63%),其次是尿素(76.40%)和细菌总数(78.09%)。结论常州市游泳池整体水质状况仍然相对较差,应继续加强游泳场馆日常监管。
