摘　　要：为研究好氧矿化垃圾床处理垃圾渗滤液较优水力负荷,采用有机负荷为0.106 g/(kg·d)、氨氮负荷为0.010g/(kg·d)的垃圾渗滤液,研究4个水力负荷0.012,0.024,0.036,0.048 L/(kg·d)下出水水质。结果表明:好氧矿化垃圾处理垃圾渗滤液的较优水力负荷为0.024 L/(kg·d),在该水力负荷下,COD、氨氮、总氮去除率分别为96.46%,99.41%,90.49%,出水p H值趋于中性;氨氮与COD耐受负荷分别为0.058和0.408 g/(kg·d)。In order to optimize the hydraulic load of leachate that was treated aerobically by aged-refuse-based bioreactor, the experiments were designed to analyze the effluent water quality with 4 different hydraulic load and fixed the organic load of injection as 0.106 g/kg and ammonia nitrogen load as 0.010 g/（kg＆#183;d）. The effluent water quality in 4 different hydraulic load which were：0.012,0.024,0.036,0.048L/（kg＆#183;d）. The results showed that the optimum hydraulic load was 0.024 L/（kg＆#183;d）, and under this hydraulic load, removal efficiency of COD, ammonia nitrogen, total nitrogen were 96.46%, 99.41%, 90.49%respectively. The pH tended to about neutral. Ammonia nitrogen and COD resistance load respectively were 0.058, 0.408 g/（kg＆#183;d）respectively.
