摘　　要：基于流离和多相生物反应原理开发了厌氧/好氧耦合生物反应器,并考察了该反应器的除污效能及污泥减量效果。研究表明,当耦合生物反应器的进水COD负荷从0.64 kgCOD/(m3.d)上升到1.58 kgCOD/(m3.d)时,对COD的去除率均在80%以上,即其能承受较大的COD负荷;该反应器具有较好的脱氮性能,在常温、HRT为8 h的条件下,对总氮的去除率>55%;它的污泥平均产率为0.028 5 kgMLSS/kgCOD,与现有污水处理工艺相比,其污泥减量效果显著。An anaerobic/aerobic coupling bioreactor was developed on the basis of separate flow and multi-phase reaction principle. The pollutants removal and sludge reduction of the reactor was investigated. The results show that when the influent COD load increases from 0.64 kgCOD/（m^3 · d） to 1.58 kgCOD/（m^3 · d） , the average removal rate of COD is above 80%. Also, large COD loads can be handled. The reactor proves with excellent nitrification ability. Ambient temperature and 8 h HRT conditions can result in above 55% total nitrogen removal rate. The average sludge production rate is only 0. 028 5 kgMLSS/kgCOD. Compared with the existing wastewater treatment processes, sludge reduction perform- ance of the coupling bioreaetor is remarkable.
