摘要: 采用氨吹脱-两级矿化垃圾床组合工艺处理晚期垃圾渗滤液，对出水中的有机物进行分子质量分布及三维荧光特性分析。针对出水有机物特征及14项出水水质指标，提出联合Ac-Fenton技术进行深度处理，并正交分析深度处理的最佳工艺条件。研究结果表明：两级矿化垃圾床对各分子质量DOM的去除均可达70%~80%，且更易于去除可见区类富里酸，但出水仍以-1，H2O2投加量为0.15 mol·L-1，H2O2/Fe2+为2：1，pH为3.0时，Ac-Fenton工艺处理效能达最佳，此时该组合工艺对色度、COD、BOD5及TN去除效能分别达99.2%、97.6%、97.4%、98.1%，且14项水质指标均能满足GB 16889-2008，实现达标排放。

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 -1,H2O2 dosage of 0.15 mol·L-1,H2O2/Fe2+ of 2:1 and pH of 3.0. Synchronously, the total removal rate of color, COD,BOD5 and 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.
