| 摘 要： | 在严格控制试验条件的基础上，首次采用缺氧/厌氧UASB-SBR生化系统处理高氨氮垃圾渗滤液结果表明，经过5个阶
段(116 d)的连续运行，获得了稳定的工艺性能在进水COD为1 237.2～12 596.8 mg/L条件下，出水COD稳定在108.4～528.26 mg/L；在进水NH4+-N为155.8～1 298.0mg/L的条件下，出水NH4+-N稳定在0.12～4.1 mg/L，实现了有机物及氨氮的深度去除.SBR采用硝化出水回流的运行方式，对原水既有一定的稀释作用，又可使富含NOx-N的硝化液借助原水中丰富的有机碳
源在缺氧UASB内进行反硝化，实现生物脱氮及降解有机物的双重目的缺氧UASB1、厌氧UASB2和SBR反应器的OLRmax(以COD计)分别为13、2.09、2.14 kg/(m3·d)UASB1、UASB2和SBR的OLR与相应的OLRrem 均呈现较好的线性关系.SBR的NLR(以氮计)与NLRrem也呈现较好线性相关此外，3个反应器的OLR与去除率(η)呈二次相关另外，SBR实现了氨氮的真正去除.整个试验过程中，SBR反应器在室温下运行，硝化阶段溶解氧低于1.0 mg/L，进水温度从20.7℃逐渐降低至10.3℃，SBR的硝化率和反硝化率始终维持在98.5％和97.7％以上，实现了深度脱氮
