摘要: 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。Abstract: An innovative ozoneinitiated 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 m3 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 m3/h with a running time of 12 hours. Compared with the salt electrolysis water treatment system, the ozoneinitiated disinfection system is more effective at the beginning of operation, much safer with more stable effluent quality, and more profitable with lower operation costs.
