摘　　要：试验采用催化氧化-A/O工艺-生物滤池组合工艺,以高浓度有机胺废水为研究对象,重点考察了该工艺对进水COD、氨氮和总氮的去除效果。结果表明:采用催化氧化预处理工艺,能有效降低废水中的抑制性物质,提高废水的B/C;A/O工艺能去除大量的有机物和总氮,但出水氨氮有所升高;末端采用生物滤池处理该废水,能有效降低废水中的氨氮和COD。当进水ρ(COD)为3 000～4 000 mg/L、ρ(NH3-N)为15～60 mg/L、ρ(TN)为350～450 mg/L时,出水水质可达当地环保要求的排放标准:ρ(COD)≤300 mg/L、ρ(NH3-N)≤35mg/L,表明该工艺可应用于高浓度有机胺废水的处理。Through the object of study on the high concentration organic amine wastewater,the removal efficiencies of COD,NH3-N and TN of the wastewater by catalytic oxidation-A/O-biological aerated filter（BAF） process were investigated.The results show that catalytic oxidation process can reduce the inhibitory substances effectively and improve B/C of the wastewater;a lot of organic matters and TN can be removed by A/O process,but effluent NH3-N increased;biological aerated filter process can reduce the COD and NH3-N effectively.When the influent COD is 3 000 to 4 000 mg/L,NH3-N is 15 to 60 mg/L,TN is 350 to 450 mg/L,the effluent COD is below 300 mg/L,NH3-N is below 35 mg/L,which can meet the requirements of the local pollutant discharge standard;it also shows that the process can be used for treatment of high concentration organic amine wastewater.
