摘　　要：本文将膜分离技术和三相流化床相结合,重点研究结合后的新技术膜生物流化床在挂膜期间以及挂膜成功后氮的去除情况。试验结果表明,膜生物流化床稳定运行期间氨氮去除率能达到95%以上,总氮去除率在70%以上,并且反硝化作用还能进一步提高。By combining membrane separation technology with three-phase fluidized bed, the removal of nitrogenous substances during and after biofllm growth by a new biological fluidized bed was investigated emphatically.It was shown that,during stable operation, NH3-N removal rate of biological membrane fluidized bed could reach to over 95%,and TP removal rate over 70%, furthermore,the denitrification action could be further raised.
