【摘要】 目的:建立一种用催化-臭氧方法氧化游泳池水中尿素,以使得游泳池水中的尿素、细菌总数、大肠菌群指标符合国家标准。方法:用不同的方法,如改性沸石过滤试验;加氯试验;臭氧氧化试验;臭氧加入催化剂(催化剂为硫酸铜或五氧化二矾)等试验观察尿素的去除效果。结果:催化-臭氧方法去除尿素效果最好,臭氧加入以硫酸铜为催化剂的催化方法尿素去除率为76.3%,臭氧加入以五氧化二矾为催化剂的催化方法尿素去除率为76.8%,高浓度氯(有效氯含量5.0 mg/L)消毒剂效果次之,去除率为46.1%。结论:理想的去除游泳池水尿素及杀灭细菌的有效方法为臭氧发生器连接游泳池本身的循环水处理系统。更多还原

【Abstract】 Objetive:To establish ozone catalytic decomposition technique to oxidize the urea and make the concentration of urea,aerobic bacterial count,coliform bacteria count in swimming pool water meet the national standard requirement.Methods:Modification zeolite filtration test,chlorine-adding test,ozonation test,ozone catalyst-adding test(catalyst is CuSO4 or V2O5) were conducted to treat the pool water and the urea removal effect of different methods was compared.Results:The best urea removaling method was ozone catalytic decomposition technique.Urea removal rate of that with the CuSO4 and V2O5 catalyst were 76.3% and 76.8%,respectively.The removal rate of high concentration chlorine(Efficient content 5.0 mg/L) was 46.1%,which took the second place in all above methods.Conclusion:Installing ozone generator combined with circulation water treatment system of the swimming pool is the ideal strategy for removal of the urea and disinfection in swimming pool water.更多还原
