摘　　要：某OCC制浆造纸企业新建了一座容积2900 m^(3)的IC厌氧反应器,并引入来自同类废水的厌氧颗粒污泥。启动21天后,IC厌氧反应器运行效果达到设计负荷,OCC制浆造纸废水处理量为15000 m^(3)/d,CODCr处理量为50000 kg/d,CODCr去除率72%~86%,出水挥发性脂肪酸稳定保持在30~110 mg/L,IC厌氧反应器在较短时间内完成效率提升。A new 2900 m^(3)IC anaerobic reactor had been built by an OCC papermaking company,and the anaerobic granular sludge from the same kind of wastewater was introduced.After starting up for 21 d,the IC anaerobic reactor reached the design loading and could treat OCC wastewater for 15000 m^(3)/d with total CODCr for 50000 kg/d.The CODCr removal rate was 72%~86%,and the VFA of reactor outlet wa⁃ter remained 30~110 mg/L,indicating the new IC anaerobic reactor can improve efficiency in a short time.
