摘　　要：将厌氧好氧水处理生物工艺和组合式人工湿地生态工艺相结合,建立生物-生态组合式人工湿地净化系统。在该系统的组合式人工湿地引入多级厌氧好氧环境,研究厌氧好氧环境下生态组合式人工湿地对低浓度污水的处理效果。经系统模型实验,处理达到GB 18918—2002《城镇污水处理厂污染物排放标准》一级A标准的市政尾水,在形成两级厌氧好氧环境后的生态组合式人工湿地中,COD、氨氮、总氮、总磷的去除效果,较未形成两级厌氧好氧环境的生态组合式人工湿地分别提高了35.28%,47.66%,25.66%,10.87%。Combine the anaerobic-aerobic water treatment biological process with the combined constructed wetland ecological process to establish a biological-ecological combined constructed wetland purification system.A multi-stage anaerobic and aerobic environment was introduced into the combined constructed wetland of the system to study the treatment effect of the ecological combined constructed wetland on low-concentration sewage under the anaerobic-aerobic environment.Through the system model experiment,the municipal tail water that meets the grade A standard of GB 18918-2002 is treated after the formation of the two-level anaerobic and aerobic environment constructed wetland,and the removal effect of COD,ammonia nitrogen,total nitrogen and total phosphorus is compared with that of without two-level anaerobic and aerobic environment ecological combined constructed wetland,the removal rates of the constructed wetlands system with two-level anaerobic and aerobic environment increased by 35.28%,47.66%,25.66%and 10.87%respectively.
