  • 摘要: 针对垃圾渗滤液成分复杂、污染物浓度高、可生化性差等特点,采用铝铁复合淀粉(CAFS)絮凝-微波/H2O2联用技术对垃圾渗滤液进行处理,考察了初始pH、絮凝剂投加量、微波辐射反应时间和H2O2投加量等因素对处理水质的影响。结果表明,絮凝最佳反应条件为pH 6.0,投加量13 mL/L;微波/H2O2氧化的最佳反应条件为pH 3.0,30% H2O2 25 mL/L,温度70℃,反应时间5 min。在上述最佳条件下,单独CAFS絮凝、单独微波/H2O2和CAFS絮凝-微波/H2O2联用对垃圾渗滤液COD的去除率分别为32.3%、42.4%和85.7%,CAFS絮凝与微波/H2O2联用,可利用CAFS残余的Fe2+与H2O2构成Fenton氧化体系,实现絮凝与微波催化氧化工艺的耦合,两者起到很好的协同作用。
    Abstract: The coupled process of combined aluminum-ferrous-starch (CAFS) flocculation-microwave/H2O2 oxidation was employed to treat the landfill leachate,and the optimally operational conditions for the COD removal were investigated.The results indicated that the optimal CAFS dosage of flocculation was 13 mL/L and the optimal pH was 6.0.The optimal parameters for microwave/H2O2 oxidation were determined as follows:initial pH was 3.0,dosage of 30% H2O2 was 25mL/L,reaction temperature was 70℃ and radiation time was 10 min.Under optimal conditions,the COD removal efficiencies of single CAFS flocculation,single microwave/H2O2 oxidation and the combination of both treatments reached 32.3%,42.4% and 85.7%,respectively,which showed a synergetic effect existed between the CAFS flocculation and the microwave/H2O2 oxidation.
