摘要：
The efficiency of BOD(5) removal in a bioreactor using conventional activated sludge technology was compared to BOD(5) removal in a hybrid reactor The comparison was based on mathematical models of both bioreactors considering substrate diffusion into the biofilm and growth kinetics of microorganisms in the activated sludge The results from the simulation show that a greater reduction of organic substances occurs in the hybrid bioreactor compared to the reactor using conventional activated sludge Moreover, it was demonstrated that a greater number of packets per filter bed and an increase in sewage recirculation from the secondary settlement tank lead to an improved efficiency of BOD(5) removal from wastewater
