摘　　要：目前,IMD新型高效厌氧消化反应器被广泛应用于高浓度有机浆液的处理。本研究考察了IMD厌氧消化处理中试运行情况,为工程扩大应用提供参考。结果表明,在中温(35℃)条件下,VS有机负荷为7.0 kgVS/m^(3)·d时,COD去除率超过80%,出料碱度平均为16565 mg/L,VFA平均为3285 mg/L,VFA/碱度比值为0.2,吨餐厨垃圾浆液产气率平均为84 m^(3),平均VS产气率为1.23 m^(3)/kgVS,表明系统稳定性较好。与其他厌氧反应器相比,IMD结构简单,设备检修维护方便,处理餐厨浆液可达到较高的有机负荷,有机物去除效率高。At present,IMD new high-efficiency anaerobic digestion reactor is widely used in the treatment of high concentration organic slurry.In this study,the pilot operation of IMD anaerobic digestion treatment was investigated to provide reference for the expansion of engineering applications.The results show that under the condition of medium temperature(35℃),when the VS organic load is 7.0 kgVS/m3·d,the COD removal rate is more than 80%,the average discharge alkalinity is 16565 mg/L,the average VFA is 3285 mg/L,the VFA/alkalinity ratio is 0.2,the average gas production rate of tons of kitchen waste slurry is 84 m3,and the average VS gas production rate is 1.23 m³/kgVS,indicating that the system has good stability.Compared with other anaerobic reactors,IMD has the advantages of simple structure,convenient equipment maintenance,high organic load and high organic matter removal efficiency.
