针对矿化垃圾反应器处理中晚期垃圾渗滤液时由于反硝化区缺少碳源而导致总氮去除率不佳的问题,开展以优先利用原水中的有机物充当碳源为目的的两段式进水两级矿化垃圾反应器处理工艺的研究.通过控制反应器的曝气量、好氧区和反硝化区,研究了两段式进水两级矿化垃圾反应器处理垃圾渗滤液的效果.结果表明,当进水渗滤液水力负荷为46.0 L/(m3·d)时,在第一级反应器底部曝气量为1.86 m3/(m3 · d),第二级反应器中上部曝气量为0.37 m3/(m3·d)的条件下,COD、NH4+-N、TP的平均去除率分别为84.1％、92.6％、85.6％,运行稳定后TN平均去除率达76.0％,处理效果较好.%Lack of carbon source at the denitrification resulted a low nitrogen removal efficiency when conventional aged refuse reactor was used to treat metaphase landfill leachate.A two-point-influent aged refuse reactor was proposed to use organic matter of raw leachate as a carbon source in this test.By controlling the aeration reactor,the aerobic zone and denitrification zone,the treatment effect of two-stage aged refuse reactor with two-feed for landfill leachate was researched.The result showed that with the conditions of the first stage reactor aerated from bottom (aeration rate 1.86 m3/(m3· d))and the second-stage reactor aerated in the upper part (aeration rate 0.37 m3/(m3 · d)),average removal rates of COD,ammonia,TP were 84.1％,92.6％,85.6％,respecially.TN removal efficience had improved greatly compared with ordinary aged refuse reactor,whose removal rate was 76.0％ as running stable.
