摘　　要：鉴于主流厌氧脱氮工艺在处理生活污水上存在的问题,文章首先根据厌氧出水的成分分析了后续处理单元可能发生的微生物代谢过程,其中抑制亚硝酸氧化细菌的生长是实现主流生活污水短程硝化的关键.其次,比较了一体式和分体式反应器构型对脱氮性能的影响.因此,今后的研究重点应该基于模型模拟和在线监控技术优化反应器构型,完善运行策略.Given the bottlenecks of mainstream anaerobic nitrogen removal process in treating domestic wastewater, the possible biological metabolic processes in treating anaerobic effluent were analyzed according to its components. In particular, controlling the growth of nitrite oxidizing bacteria was the key to achieve stable performance of mainstream partial nitrification. The effects of integrative and split bioreaetor configurations on nitrogen removal performance were also compared. Further researches should focus on optimizing reactor configurations and improving operation strategies on the basis of model simulation and on line monitoring.
