武汉市部分游泳池水水质卫生状况抽检结果分析研究

Analysis and research on the sanitary condition in swimming pool water in Wuhan

目的了解武汉市游泳池水水质卫生状况,为监管部门提供科学的管理依据,进一步提高泳池水水质卫生质量,保障游泳者身体健康。方法按照GB/T 5750-2006《生活饮用水标准检验法》对p H值、浑浊度、游离性余氯指标进行检测;按照GB/T 18204. 9-2000《游泳池水微生物检验方法》对大肠菌群、细菌总数指标进行检测;按照GB/T18204. 29-2000《游泳水中尿素测定方法》对尿素指标进行检测;根据GB 9667-1996《游泳场所卫生标准》的限值要求进行评价。结果共检测游泳池水水样20份,合格8份,合格率为40. 0%;检测浸脚池水水样7份,合格6份,合格率为85. 7%。泳池水游离性余氯合格率最低,仅45. 0%,是水样不合格的主要原因。酒店附属类泳池细菌总数合格率低于社会经营和专业场馆类,差异有统计学意义(χ~2=8. 889,P <0. 05)。结论武汉市游泳池水水卫生状况待进一步改善,应加强对游泳场所的卫生监管。
