PEM式臭氧消毒在地上游泳池水处理中的应用

Disinfection of water in aboveground swimming pools using PEM electrolyzing ozone generators

采用臭氧法水处理系统对地上游泳池的循环水进行灭菌消毒,研究了臭氧用量、循环水流量和运行时间等因素对臭氧法灭菌效果的影响。结果表明,3组PEM臭氧发生器应用于21.2 m3的地上游泳池,在4 m3/h的循环水流量下运行12 h后,水中的细菌总数与大肠杆菌群数达到国家标准,去除率均在99%以上。与盐电解法水处理系统相比较,臭氧法水处理系统的优势在于:杀菌快速高效、出水水质的理化指标较好和运行费用低廉。

An innovative ozone-initiated disinfection system was developed against the problem of microbe growth in aboveground swimming pools.Effects of ozone dose,circulating water flow and running time on disinfection of water in a 21.2 m^3 aboveground swimming pool were investigated.The sterilization rates of total bacteria and Escherichia coli groups reached above 99% under the optimal operational conditions： 3 PEM electrolyzing ozone generators,the circulating water flow of 4 m^3/h with a running time of 12 hours.Compared with the salt electrolysis water treatment system,the ozone-initiated disinfection system is more effective at the beginning of operation,much safer with more stable effluent quality,and more profitable with lower operation costs.
