摘　　要：采用EGSB厌氧反应器处理某生活垃圾焚烧厂垃圾渗滤液，设计处理能力为200m^3／d，容积负荷为11．2kg／（m^3·d），单个反应器尺寸为φ9m×25m。运行数据表明，EGSB处理生活垃圾焚烧厂渗滤液具有很强的耐冲击负荷能力，运行过程中实际处理水量为50—305m^3／d、COD容积负荷为2—17．6kg／（m^3·d）、ALK为7500～14000mg／L、VFA最高为7284mg／L、vFA／ALK为O．01～0．55，系统出水pH值〉7．7，COD去除率均较为稳定（80％～95％），出水COD稳定在1500～2000mg／L。沼气产率为0．4—0．5m^3／kgCOD，沼气中甲烷含量为71％～78％。An expanded granular sludge bed （EGSB） reactor was used to treat the leachate from a municipal solid waste incineration plant. The design treatment capacity was 200 m^3/d, and the design COD volume load was 11.2 kg/（ m^3·d）. The single reactor has a diameter of 9 m and a length of 25 m. The operation results showed that EGSB reactor had a strong anti-impact load. The actual treatment ca- pacity was 50 to 305 m^3/d. The actual COD volume load was 2 to 17.6 kg/（ m^3· d）. ALK was 7 500 to 14 000 mg/L. The maximum VFA was 7 284 mg/L. VFA/ALK was 0.01 to 0.55. The effluent pH was above 7.7. The COD removal efficiency was about 80% to 95%. The effluent COD was 1 500 to 2 000 mg/L. Biogas production rate was 0.4 to 0.5 m^3/kgCOD, and the methane content of biogas was 71% to 78%.
