摘要 采用O3+BAC生物滤池组合工艺对酿酒废水生化处理出水进行深度处理实验研究。结果表明,O3氧化投加量为20~30 mg/L,可满足脱色要求;O3单位投加量超过80 mg/L时,可满足出水COD要求;O3+H2O2高级氧化工艺相比O3直接氧化可节约O3投加量约30 mg/L;对氧化出水进行BAC生物滤池处理,可进一步去除COD约28%左右。“O3+H2O2/BAC”组合工艺发挥了化学氧化和生物降解的协同降解效果,在酿酒废水深度处理中具有较强的经济性和工程应用价值。 A batch-scale study on combined process of ozonation-BAC biofilter for advanced treatment of biochemical treated effluent of distilled spirit wastewater was conducted. The results showed that requirements for the removal of color could be reached when ozone dosage was 20~30 mg/L, and requirements for effluent COD could be satisfied when ozone dosage was 80mg/L. Advanced oxidation process of O3+H2O2could save ozone dose of about 30 mg/L compared to direct ozonation process. The COD removal of oxidated effluent after BAC biofilter was about 28%. With good synergy degradation effect of chemical oxidation and biological degradation, the combined process of O3+H2O2/BAC has strong economic and engineering application values for advanced treatment of distilled spirit wastewater.
