游泳池水质理化和微生物的检测与分析

目的:了解杭州市上城区游泳池的水质卫生状况,为加强游泳池的卫生管理提供科学依据。方法:对上城区2008年-2010年3年的游泳池水质理化指标4项分别为:pH值、浑浊度、游离性余氯及尿素;微生物指标2项分别为:细菌总数及大肠菌群,采用国家标准检验方法进行检验,并对检测结果进行统计分析。结果:3年游泳池水合格率较高的是浑浊度与pH值均为100.0%;其次为大肠菌群合格率依次为100%、95.7%、97.9%和游离性余氯合格率依次为100%、87.1%、97.1%;较差的为细菌总数合格率依次为89.3%、94.8%、88.6%和尿素合格率依次为78.6%、87.1%、91.4%;3年水样总体合格率不高依次为82.1%、70.7%、77.1%。结论:上城区游泳池水质卫生状况不容乐观,应加大对游泳场所的卫生监督管理。

Physical and chemical and microbiological detection and analysis of water quality in swimming pools

Objective:To evaluate the health conditions of water quality in swimming pools for Shangcheng district in Hangzhou,and provide scientific basis to strengthen the hygiene management of swimming pools.Methods:Health indexes including physical and chemical indexes(pH value,turbidity value,residual free chlorine and urea) and microbiological indexes(bacteria and coliform group) were detected for the water of swimming pools in the past three years from 2008 to 2010.The data were statistically analyzed.Results:The percent of pass was 100.0% for the pH value and the turbidity value,100%,87.1% and 97.1% for the residual free chlorine,78.6%,87.1% and 91.4% for the urea,89.3%,94.8% and 88.6% for the total bacterial count,100.0%,95.7% and 97.9% for the Coliform group respectively in the past three years.The general percents of pass were 82.1%,70.7% and 77.1% respectively.Conclusion:The quality of the water of swimming pools in Shangcheng district was not so optimistic.The health supervision department shall regularly monitor the health indexes of the water of swimming pools.
