采用内循环厌氧反应器（IC）处理餐厨垃圾废水。结果表明：采用快速提升负荷至5 kg/（m3·d）并稳定运行19 d这一启动方式有利于提高污泥的活性。负荷提升中后期，出水pH高于进水pH。IC处理餐厨垃圾废水的最大容积负荷为25.2 kg/（m3·d），此时COD去除率下降到86%。稳定运行期，当进水COD达到22.4 mg/L，出水COD稳定在1650~1950 mg/L，COD去除率高达91.8%。

The new type of internal circulation (IC ) reactor has been used for treating the wastewater from food waste water. The results show that in the start-up period,the start-up form of raising the load rapidly to 5 kg/(m3·d) and running the system steadily for 19 d,is good for improving the sludge activity. In the mid late period of load lifting,the pH of effluent is higher than that of influent. The maximum volume load of food-waste wastewater treated by IC reactor is 25.2 kg/(m3·d). At this time,the COD removing rate declines to 86%. In the steadily running period,when COD concentration of influent reaches 22.4 mg/L,the COD concentration of effluent stabilizes between 1 650-1 950 mg/L,and the COD removing rate reaches 91.8%.
