天津市游泳池水质检测结果分析与对策

目的收集天津市4年来游泳池水质检测结果，分析游泳池水质存在的主要问题，旨在提出应对的方法。方法按《公共场所卫生标准检验方法》（GB／T18204—2000）进行检测，按《游泳池场所卫生标准》（GB9667—1996）进行评价。结果2009--2012年天津市游泳池水质，其中余氯、尿素合格率较低。游离性余氯合格率仅为35％～55％，尿素合格率为70％～81％，细菌总数合格率为89％一93％，大肠菌群合格率95％～99％。余氯含量越高，微生物指标合格率越高。结论该市游泳池水质存在2个主要问题：池水游离性余氯忽高忽低，说明水质处理人员不能按池水量和游泳人数科学投药；尿素含量过高，说明不能及时补充合格新水。尽管细菌总数和大肠菌群合格率偏高，这是因为一些游泳池过量的加入消毒药所致，过量的加入消毒剂也会给游泳者带来一定的潜在危害，应引起广泛关注。

Test results and countermeasures of water quality of swimming pool in Tianjin City

Objective ] To collect the test results of water quality of swimming pool in Tianjin City in recent 4 years, to analyze the existed problem, and put forward coping method. Methods ] The detection was based on＂ Hygienic Standard Test Method for Pub- lic Places＂ GB/T 18204-2000, and the evaluation was based on ＂Health Standards for Swimming Pool＂GB 9667-1996. Results] The test results of swimming pool during 2009-2012 showed that the qualified rates of chlorine and urea were relatively low; the qualified rate of rree residual chlorine, urea, total bacteria, coliform group was 35%-55%, 70%-81%, 89%-93%, 95%-99%, respectively ; the higher chlorine content was, the higher pass rates of microbial indicators had. Conclusion ] There are 2 major problems about swimming pool water. One is residual chlorine unstable fluctuation that lack of scientific administration. The other is urea content is too high, failed to timely supplementing qualified new water. The high qualified rates of total bacterial count and coliform bacteria indicates excessive disinfectant added in some swimming pool which may also be a potential danger to the swimmer, and should arouse wide public concern.
