2008—2010年清远市区游泳池水水质卫生监测分析

Surveillance and analysis on water quality of swimming pools in Qingyuan urban area from 2008-2010

目的了解清远市区人工游泳池的水质卫生状况和变化趋势,为进一步加强游泳场所卫生管理提供科学依据。方法对清远市区游泳池水水质按照GB/T 18204.2000《公共场所卫生标准检验方法》、GB/T 5750-2006《生活饮用水标准检验方法》进行细菌总数、大肠菌群、浑浊度、pH值、游离性余氯、尿素等项目进行检验。并对2008—2010年的检测结果进行统计分析。结果共检测水样530份,各项指标全部合格的162份,合格率为29.45%,其中合格率最低的项目主要为尿素(39.82%)、游离性余氯(80.18%),其次为大肠菌群(99.27%)和细菌总数(96.91%);公共泳池水质合格率(55.17%)高于住宅小区(35.07%)和酒店内游泳场所(20.36%),游泳旺季合格率(24.01%)低于游泳淡季(36.18%)。结论近年清远市区游泳池水质卫生状况不佳,市卫生监督部门要重点加强酒店内泳池和住宅小区内泳池的监管,提高水质卫生质量,保障游泳者身体健康。
