氨吹脱-两级矿化垃圾-Ac-Fenton处理晚期垃圾渗滤液
Treatment of mature landfill leachate with ammonia stripping-two-stage aged refuse bioreactor-Ac-Fenton process
摘要
Abstract
Ammonia stripping-two-stage aged refuse bioreactor process was applied to treat late landfill leachate.According to the molecular weight distribution of organics and the three-dimensional fluorescence characteristics of the effluent from this combined process, Ac-Fenton was proposed as the advanced treatment technology by comparing 14 water quality parameters with the discharge standard and the optimal process conditions were examined based on orthogonal analysis.Research results show that the removal rate of various DOM molecular weights by the two-stage aged refuse bioreactor could reach 70％ to 80％ , and the removal of fulvic acid of visible region was relatively easier.The fulvic acid with molecular weight < 5 kDa was still the primary component of Ac-Fenton effluent.The optimum condition of Ac-Fenton process was active carbon dosage of 4.0 g · L-1, H2O2 dosage of0.15 mol · L-1 ,H2O2/Fe2+ of 2∶1 and pH of 3.0.Synchronously, the total removal rate of color, COD, BOD5and TN could reach 99.2％ , 97.6％ , 97.4％ , 98.1％, respectively, and 14 water quality parameters could also meet the discharge standards GB 16889-2008.关键词
