上海市闵行区游泳场所水质监测情况分析

目的 通过对上海市闵行区游泳场所卫生状况的现场调查和对游泳池水的监督抽检，了解闵行区游泳场所水质卫生状况及主要问题，分析可能的影响因素，探讨卫生监管对策。方法 编制闵行区游泳场所卫生设施设备现场调查表，对辖区内取得《上海市公共场所卫生许可证》并正常开放的游泳场所基本情况开展调查，对正常开放的游泳场所水质进行现场采样和检测并对结果进行统计分析。结果 闵行区游泳场所主要以中、小型为主，在从业人员健康合格证和消毒剂使用方面管理情况良好，在安装强制淋浴设施、补充新水专用水表等方面尚未普及。游泳场所水质抽检总合格率为62.50%（110/176），6项指标合格率从低到高依次为:余氯76.14%（134/176）、尿素79.55%（140/176）、细菌总数96.59%（170/176），总大肠菌群、浑浊度和pH，均为100.00%。常年开放游泳场所抽检总合格率为50.00%（44/88），夏季开放游泳场所总合格率为75.00%（66/88），两者差异具有统计学意义（P＜0.05）。常年开放和夏季开放游泳场所的尿素检测合格率比较，统计学意义显著（P＜0.01）。结论 闵行区游泳场所水质污染主要是尿素超标，一方面要升级改造卫生设施设备，控制尿素来源；另一方面要加强对常年开放游泳场所的水质抽检频次，加大对违法行为的处罚力度，督促游泳场所及时、足量补充新水，同时要引导舆论监督力量，共同形成合力，提高行业卫生水平，保障泳客健康。

Analysis on Water Quality Monitoring of SwimmingPlaces in Minhang District,Shanghai City

Abstract:Objective To understand the water quality and main problems of swimming places in Minhang District by on-the-spot investigation of the sanitary conditions of swimming places in Minhang District, Shanghai, and to analyze the possible influencing factors and to explore the countermeasures for health supervision. Methods To prepare an on-site questionnaire for the sanitary facilities and equipment of swimming places in Minhang District, and conduct an investigation on the basic conditions of swimming places that have obtained the "Shanghai Public Places Sanitation Permit" in the jurisdiction and open normally, and conduct on-site sampling and testing of the water quality of swimming pools that are normally open, and statistical analysis of the results. Results The swimming places in Minhang District are mainly medium and small, and the management of the health certificate and disinfectant use of the employees is good. It has not been widely used in the installation of forced shower facilities and water meters for new water. The total qualified rate of water sampling in swimming places was 62.50%(110/176). The qualified rate of six indicators from low to high was: residual chlorine 76.14%(134/176), urea 79.55%(140/176), total bacteria 96.59%(170/176), total coliform, turbidity and pH, both 100.00%. The total pass rate of open swimming sampling was 50.00%(44/88), and the total qualified rate of open swimming places in summer was 75.00%(66/88),the difference was statistically significant(P<0.05). The urea test pass rate of the open year and open swimming places in summer was statistically significant(P<0.01).Conclusion The water pollution in swimming places in Minhang District is mainly due to excessive urea. On the one hand, it is necessary to upgrade and renovate sanitary facilities and control the source of urea. On the other hand, it is necessary to strengthen the frequency of sampling of water in the open swimming places all year round, and increase the punishment for illegal activities. The swimming place should supplement the new water in time and in sufficient quantity. At the same time, it is necessary to guide the supervision power of the public to jointly form a joint force, improve the health level of the industry, and ensure the health of swimmers.
