摘　　要：CSTR—UASB两相厌氧反应器的原理如下：CSTR采用复合红糖水作为发酵底物，其液体的最终产品是UASB反应底物。污水处理厂污泥作为反应器的起始污泥。反应器运行稳定后，我们可以通过改变有机负荷对两相厌氧CSTR—UASB系统的影响。结果表明，厌氧污泥产氢能力将继续上升六个阶段，有机负荷的含量逐渐提高，并在有机负荷达到最大，产氢能力达到最大。随着有机负荷的增加，甲烷的甲烷量先增大后减小。我们发现，有机负荷为28公斤／（蹦米37D）同时，COD的总去除率达到最大值。因此，CsTR—UASB两相厌氧系统对红糖废水的降解，使在废s水再利用方面的差异。Pprinciples of CSTR - UASB two - phase anaerobic reactor are as foUows ： CSTR uses the compounded brown sugar water as a fermentative substrate, whose liquid end product is the reactive substrate of UASB. The sludge in Sewage treatment plant is as the starting sludge of reactor. After the reactor runs stably, we can study its effect on the two - phase anaerol^ic CSTR - UASB system by changing the organic load. The results show that hydrogen the organi productive capacity from the anaerobic sludge will continue to rise by the six stages that the content of c load improves gradually, and after the organic load achieves maximum, the capacity of hydrogen pro- duction has reached its maximum. The amount of methane with organic load will increase firstly then decrease. We find that the organic load is 28kg/（ m3 d） at the same time, the total COD removal rate will reach a maxi- mum. Therefore, CSTR- UASB two -phase anaerobic system has good which has made a difference in terms of reusing wastewater.
