采用2套UASB-ANAMMOX反应器处理垃圾渗滤液,其中反应器2具有生物膜,对反应器在有机环境下的ANAMMOX与反硝化协同作用进行对比研究.在稳定期,反应器1和反应器2对氨氮、亚硝氮、TIN、COD的平均去除率分别为95.7%、95.9%、77.3%、70.3%和97.4%、96.4%、87.2%、74.8%.反应器1对TIN和COD最大容积去除率为112.2和107.7 g/(m~3·d),反应器2对TIN和COD最大容积去除率为120.5和119.9 g/(m~3·d).结果表明,过高的负荷会对反应器产生抑制作用,且当抑制产生后协同作用难以恢复到原来水平.在厌氧氨氧化与反硝化协同作用良好时,pH值和碱度均存在特征性变化.总体上,反应器2比反应器1具有更强的厌氧氨氧化与反硝化协同作用和抗负荷冲击能力.

Comparative study on treatment of the diluted leachate, by anaerobic ammonium oxidation ( AN-AMMOX) coupled with denitrification, was carried out with two upflow anaerobic sludge blanket (UASB) reac-tors, reactor 2 with biofilm and reactor 1 without it. During the steady states, the average removal efficiencies of ammonium, nitrite, TIN and COD in reactor 1 were 95. 7% ,95. 9% ,77. 3% ,70. 3% , and corresponding to that in reactor 2 were 97. 4% ,96. 4% ,87. 2% and 74. 8% , respectively. The maximum volumetric loading conver-sion rates of TIN and COD in reactor 1 were 112. 2 and 107. 7 g/( m~3 · d) , corresponding to that in reactor 2 were 120. 5 and 119. 9 g/(m~3 · d) , respectively. The synergism in the reactors was inhibited due to overload, and was hard to recover to the previous performance once overload taken place. When the synergism was in a good state, characteristic changes were presented in the pH value and alkalinity. Reactor 2 with biofilm was found to be more active than reactor 1 without biofilm in the synergism and in loading shock resistance.
