摘　　要：目的 了解游泳池水质卫生国家新标准GB 34788-2019《公共场所卫生指标及限值要求》实施后,重庆市渝北区游泳池水卫生状况,为制定有效的卫生监督措施提供依据。方法 于2019和2020年6-9月对重庆市渝北区游泳池水进行采样,按照GB/T 18204-2014《公共场所卫生标准检验方法》和GB/T 5750-2006《生活饮用水标准检验方法》检测pH值、尿素、浑浊度、游离性余氯、细菌总数和大肠菌群等指标,用国家新标准评价检测结果。结果 共采集并检测游泳池水162份,总体合格率为45.06%。各项检测指标中,游离性余氯合格率最低(72.22%),其次为pH(80.86%)和尿素(86.42%)。不同年份的总体合格率差异无统计学意义(P>0.05),室内与室外游泳池水质总体合格率差异无统计学差异(P>0.05)。在pH、游离性余氯指标不合格的水样中,超限样本所占百分比为62.50%和67.39%,高于低限样本。结论 国家新标准实施下,重庆市渝北区游泳池水卫生状况有待进一步提高,应做好新标准的宣传普及,进一步加强经营管理者培训,确保游泳池水质达到卫生要求。Objective To understand the sanitary situation of swimming pool water in Yubei district of Chongqing according to new national standard GB 34788-2019 "Hygienic indicators and limits for public places",and to provide scientific basis for hygiene supervision. Methods During June to September of 2019 and 2020,the water samples were collected from the swimming pools in Yubei district of Chongqing. The water hygienic indexes including pH,turbidity,urea,total bacteria and coliformbacteria were determined according to GB/T 18204-2014 "Examination methods for public places" and GB/T 5750-2006 "Standard examination methods for drinking water".The results were assessed according to the new national standard. Results A total of 162 of swimming pool water samples were collected and tested,the overall qualified rate was 45.06%. Among the water quality indicators,the qualified rate of residual chlorine(72.22%) was the lowest,then followed by pH value(80.86%) and urea(86.42%).There was no significant difference in the qualified rate between different years and indoor and outdoor swimming pools(P>0.05). For the unqualified water samples the percentage of samples above the standard value(62.50% for the pH value,and 67.39% for the residual chlorine) were higher than the samples below the standard value.Conclusion The qualified rate of the water quality in swimming pools was not high based on the new standard.The training for management staff of the swimming places should be improved. It is necessary to further strengthen the publicity of new policies,to ensure the water quality of swimming places.
