摘　　要：采用臭氧氧化和O3/H2O2高级氧化工艺对白酒废水生化处理出水的纳滤浓缩液进行试验研究。在间歇反应体系中的试验结果表明:臭氧投加速率过大时,会导致臭氧化学吸收不完全、利用率降低;臭氧单位投加量与纳滤浓缩液COD去除率之间具有良好的线性关系,在O3单位投加量(m(O3)/m(COD))为2.52时,COD去除率可达79.1%;臭氧降解COD的反应规律符合拟1级反应动力学,且属于快速动力学体系;采用O3/H2O2高级氧化工艺可有效降低臭氧投加量,COD去除率为77.6%时O3单位投加量仅需1.40。A batch study for ozonation and O3/H2O2 process to treat nanofiltration concentrate ofbiotreated distilled spirit wastewater were conducted. The experimental results showed that the ozone utilization percentage decreased as the dose rate was too high, and a good linear relationship was found between specific ozone dose （SOD） and the COD removal. The COD removal reached to 79.1% at a SOD of 2.52. The ozonation, of COD ofnanofiltration concentrate was a fast reaction and fitted well with a pseudo first order reaction kinetics. O3/H2O2 process could oxidize the nanofiltration concentrate effectively at a relatively lower ozone dose. COD removal was 77.6% at a SOD of 1.40.
