摘　　要：采用短程硝化SBR+厌氧氨氧化ASBR组合工艺、短程硝化SBR+厌氧氨氧化生物滤池组合工艺,以实际老龄垃圾渗滤液为研究对象,对比了两种组合工艺对垃圾渗滤液的处理效果,以选出更适合的组合工艺。研究发现,两种体系都能快速地对渗滤液水质作出反应。其中,SBR+厌氧氨氧化ASBR的联合技术能承受最大化的总氮容量负担,其值达到了0.280kgN∙(m^(3)∙d)^(-1);相比之下,SBR+厌氧氨氧化滤池可处理高达0.550kgN∙(m^(3)∙d)^(-1)总氮负荷。这表明,短程硝化SBR+厌氧氨氧化生物滤池的整合方法有潜力应对更高的工作量并具备较强的抗冲击性能以应对水质变化较大的情况。The research object of this study was an aged landfill,for which the short-range nitrification SBR+anaerobic ammoxidation ASBR combined process and the short-range nitrification SBR+anaerobic ammoxidation biofilter combined process were compared in terms of their treatment effects on landfill leachate,so as to select a more suitable combined process.It is found that both systems can respond to leachate quality quickly.Among them,the combined technology of SBR and anaerobic ammoxidation ASBR can bear the maximum total nitrogen capacity burden,the value of which reaches 0.280 kgN·(m^(3)·d)^(-1).In contrast,the SBR+anaerobic ammonium oxidation biofilter can handle a total nitrogen load of up to 0.550 kgN.·(m^(3)·d)^(-1).This indicates that the integrated approach of short-range nitrification SBR+anaerobic ammonium oxidation biofilter has the potential to cope with higher workload and have stronger impact resistance to cope with large water quality changes.
