摘要
目的了解白云区2008年-2012年游泳池水水质卫生状况及变化趋势,为进一步提高游泳池水卫生质量提供科学依据。方法按照GB/T18204-2000《公共场所卫生标准检验方法》对白云区210间次游泳池抽取883份水样,检测pH值、游离性余氯、尿素、浑浊度、细菌总数和大肠菌群6项指标,并进行卫生评价。结果白云区2008年-2012年游泳池水质监测总合格率为72.82%。各年度合格率分别为65.28%、80.13%、64.45%、77.16%和77.78%,经卡方检验(χ2=19.786,P<0.01)有统计学意义。浑浊度、大肠菌群合格率较高,均为100%,其次为细菌总数、尿素和pH值,合格率分别为97.40%、96.72%和96.14%。游离性余氯合格率最低,为78.94%,经卡方检验(χ2=25.648,P<0.01)有统计学意义。结论广州市白云区游泳池水水质卫生状况不容乐观,应加强游泳池卫生管理,规范其经营行为,确保水质卫生状况良好,为白云区公共卫生安全提供科学依据。
Objective To understand the hygienic quality and variation trend of swimming pool water in Baiyun district from 2008 to 2012, and provide scientific basis for further improving the hygienic quality of swimming pool water. Methods According to GB/T18204 -2000 ＂Standard testing methods for hygiene of public places＂, 883 water samples from 210 swimming pools in Baiyun district were collected to test and evaluate the pH value, residual free chlorine, earbamide, opacity, total bacteria and the coliform group. Results The general qualified rate of the swimming pool water was 72.82% in Baiyun district from 2008 to 2012. The qualified rate of each year was 65.28% , 80.13%, 64.45%, 77.16% and 77.78% respectively during the past five years, and the difference had statistical significance by chi -square test（χ2 = 19. 786, P 〈 0.01 ）. The qualified rates of the opacity and coliform group were the highest, both were 100%, followed by the total bacteria（97.40% ）, earbamide （96.72%） and the pH value （96. 14% ）. The residual free chlorine had the lowest qualified rate, only 78.94%, and the difference had statistical significance by chi - square test（χ2 = 25. 648, P 〈 0.01 ）. Conclusion The hygienic quality of swimming pool water was not optimistic in Baiyun district. It is necessary o strengthen the public health management of the swimming pool and regulate the management behaviors, so as to ensure the hygienic quality of swimming pool water well and provide scientific knowledge for the public health security in Baiyun district.
