摘　　要：评估了新型旋混式生物反应器的有效性。新型旋混式生物反应器是一种多模块系统,可在同一反应单元中耦合多个生物过程,以去除合成废水或工业废水中的含氮和含碳化合物。研究结果表明:CODs和氨的生物降解是多步骤的,取决于每个模块给定的环境条件;合成废水的化学成分影响所涉及的生物过程,通过硝化、异养活性、反硝化和产甲烷作用去除合成废水中的氨氮和CODs;而在工业废水中,通过部分硝化、异养活性和反硝化去除氨氮和CODs。采用多模块新型旋混式生物反应器是处理复杂工业废水的可行技术。The effectiveness of a novel swirl mixed bioreactor was evaluated.The novel rotary mixing bioreactor is a multi-module system that can couple multiple biological processes in the same reaction unit to remove nitrogen and carbon compounds from synthetic and industrial wastewater.The results showed that the biodegradation of CODs and ammonia was multi-step,depending on the given environmental conditions of each module.The chemical composition of synthetic wastewater affected the biological processes involved in removal of ammonia nitrogen and CODs from synthetic wastewater by nitrification,heterotrophic activity,denitrification and methanogenesis;In industrial wastewater,ammonia nitrogen and CODs were removed by partial nitrification,heterotrophic activity and denitrification.The new multi-module rotary mixing bioreactor may be a feasible technology to treat complex industrial wastewater.
