2010-2012年某市游泳池水质监测结果分析与措施

目的分析某市2010-2012年游泳池水水质卫生状况及变化趋势,发现问题及时消除隐患,提高公共游泳池水卫生质量。方法采用国家标准检验方法,对该市游泳池水的浑浊度、pH值、游离性余氯、尿素、细菌总数、大肠菌群6个项目进行检验。结果 2010-2012年间水质合格率呈逐年上升趋势;游泳旺季合格率(71.20%)低于游泳淡季(89.38%),并且差异有统计学意义;三年中游离性余氯合格率最低,其次是细菌总数、尿素,大肠菌群、pH值合格率相对较稳定,浑浊度合格率最高达100%;专营公共泳池水质合格率(80.08%)高于住宅小区游泳池(75.67%)和酒店游泳池(64.15%)。结论该市游泳池水质卫生质量逐年提高,但仍需加强对住宅小区泳池和酒店泳池的卫生监管力度,强化游泳池水消毒和定期换水。

Monitoring results and measures of water quality of swimming pool in a cityduring 2010-2012

Objective Analyzing the water quality of the swimming pool of the city about the sanitary conditions and the variational tendency during the year 2010 to 2012, finded out the problems. It was timely to eliminate potential danger and improve the sanitary quality of public swimming pool. Methods Adopting the national standard inspection ways tested the water of the swimming pool, including six items-the turbidity degree, flee residual chlorine, pH value, urea, total bacteria, coliform. Results The eligible rate of water quality tends to be fine gradually from 2010 to 2012. The eligible rate of busy swimming season （71.20%） was lower than the eligible rate of lack season （89.38%）, and the difference was statistically significant. The eligible rate of free residual chlorine was.lowest in these three years, the total bacteria and urea followed, but the eligible rate of coilform group and pH value relatively remained stable, the eligible rate of turbidity was up to 100%; the water quality index （80.08%） in the specialized public swimming pool was higher than that in the swimming pool of residential district （75.67%） and in hotel swimming poo1（64.15%）. Conclusion The hygienic quality of water quality in swimming pool of this city has been improved, but health supervision of swimming pool in residential district and hotel should yet be strengthened, enhancing water sterilization and changing water regularly.
