台州市2016年—2021年游泳池水水质卫生监测结果分析

Monitoring and results analysis of swimming pool water sanitation in Taizhou City from 2016 to 2021

目的了解台州市游泳池水水质卫生状况,为保障游泳者身体健康和进一步加强卫生监督管理提供科学依据。方法对2016年—2021年台州市游泳池水卫生监测结果进行统计分析。结果2016年—2021年共抽检游泳池水1349份,总体合格率为79.47%;不同年份的游泳池水水质合格率差异无统计学意义(P>0.05)。3类游泳场所中酒店宾馆游泳池水合格率最高(85.54%),学校游泳池水合格率最低(70.45%),差异有统计学意义(P<0.05)。6项检测项目中,浑浊度的合格率最高(100.00%),其次为pH值(97.78%)、大肠菌群(97.33%)、细菌总数(94.37%)、游离性余氯(92.88%),尿素的合格率最低(90.14%),差异有统计学意义(P<0.05)。游泳池水中游离性余氯含量低的样本细菌总数、大肠菌群不合格率相对较高。结论台州市游泳池水水质卫生状况有待进一步改善,应加强对游泳场所的监督监测与指导工作。

Objective To understand the sanitary status of swimming pool water in Taizhou City,so as to provide scientific basis for protecting swimmers from sanitary problems and further strengthening sanitary supervision and management.Methods Statistical analysis was performed on the monitoring results of swimming pool water hygiene in Taizhou City from2016 to 2021.Results A total of 1349 swimming pool waters were tested from 2016 to 2021 with the qualified rate of79.47%;there was no statistical significance on the difference in the qualified rate of swimming pool water quality in different years(P>0.05).Among the three types of swimming places,the qualified rate of hotel swimming pool water was the highest(85.54%),that of school swimming pool water was the lowest(70.45%),and there was statistical significance on the difference(P<0.05).Among the six testing items,the qualified rate of turbidity was the highest(100.0%),followed by pH(97.78%),coliform group(97.33%),total bacteria(94.37%)and free residual chlorine(92.88%),and the qualified rate of urea was the lowest(90.14%),and there was statistical significance on the difference in the qualified rate of six testing items(P<0.05).The samples with low free residual chlorine content in swimming pool water had relatively high failure rate of total bacteria and coliform.Conclusion The sanitary condition of swimming pool water quality in Taizhou City needs to be further improved,and the supervision,monitoring and guidance of swimming places should be strengthened.
