针对平原水库夏季有机物及氨氮含量高的问题进行了研究.采用滤前曝臭氧的方式,改变上层滤料的类型,对比3种滤池对水中有机物及氨氮的去除效果.结果表明,在臭氧处理前水的pH为6.84～7.32,CODMn为6.1～7.3mg/L、UV254为0.162～0.194 cm-1、NH3-N的质量浓度为1.5～2.0 mg/L的条件下,臭氧-煤砂滤池对水中CODMn、UV254及NH3-N的去除率分别为60.5％、87.3％和73.2％,臭氧-活性无烟煤-砂滤池对水中CODMn、UV254及NH3-N的去除率分别为81.3％、93.4％和88.3％,臭氧-炭砂滤池对水中CODMn、UV254及NH3-N的去除率分别为84.5％、95.2％和92.2％.3种滤池对浊度的去除率达到93％以上.相比传统煤砂滤池,采用臭氧与活性滤料联用能够提高滤池的生化性能,对季节性高有机物、高氨氮含量原水有较好的处理效果.“,”In this paper the problem of high organic matter and ammonia-nitrogen content in plain reservoir was studied.The effect on removal of organic matter and ammonia-nitrogen in water were compared by altering the types of upper media.The results show that,in the condition of pre-ozoned water whose pH ranged from 6.84 to 7.32,CODMn from 6.1～7.3 mg/L,UV254 from 0.162～0.194 cm-1 and mass concentration of NH3-N from 1.5～2.0 mg/L,the removal efficiencies of CODMn,UV254 and NH3-N were 60.5％,87.3％ and 73.2％ respectively by ozone/anthracite-sand filter.The corresponding removal rates were 81.3％,93.4％ and 88.3％ respectively by ozone/activated anthracite-sand filter as well as 84.5％,95.2％ and 92.2％ respectively by ozone/activated carbon-sand filter.The removal efficiency of turbidity could be 93％ above.Compared to conventional anthracite-sand filters,biochemical properties could be upgraded adapting active media combined with ozone,which was somehow well to the treatment of seasonal raw water containing high organic matter and NH3-N content.
