摘　　要：分析南方某水厂的臭氧活性炭深度处理工艺,并进行预臭氧和后臭氧投加量的优化试验。试验结果表明,预臭氧投加量为0.4~0.6 mg/L时,氨氮和COD_(Mn)的去除率显著提高,而过量的臭氧投加会使COD_(Mn)去除率下降。后臭氧投加量的增加显著提高了COD_(Mn)和嗅味物质的去除率,但同时进一步增加了经济成本和副产物生成风险。此外,预臭氧和后臭氧投加量对水质pH值的影响较小,综合考虑水质和经济成本,建议在实际运行中合理选择臭氧投加量,从而达到最佳的处理效果。The advanced treatment process of ozone and activated carbon in a water plant in south China was analyzed,and conduct optimization experiments on the dosage of pre-ozone and post-ozone.The experimental results show that when the dosage of pre-ozone is in the range of 0.4~0.6 mg/L,the removal rate of ammonia nitrogen andCOD_(Mn)is significantly improved,while excessive ozone dosage will decrease the removal rate ofCOD_(Mn).With the increase of post-ozone dosage,the removal rate of COD_(Mn)and odor substances was significantly improved,but at the same time,the economic cost and the risk of by-product formation were further increased.In addition,the dosage of pre-ozone and post-ozone has little influence on the pH of water quality.Considering the water quality and economic cost,it is suggested that the dosage of ozone should be reasonably selected in actual operation to achieve the best treatment effect.
