Abstract: | A combined process of TMBR and NF/RO is applied to treat leachate from a sanitary waste landfill site in Yichang ,Hubei province ,China .The technological process ,characteristics of the combination process ,equipment specifi-cations and technical parameters are introduced and the engineering experience of operating the TMBR and NF/RO combina-tion process and controlling landfill leachate are also summarized .The average concentration of COD is 822 mg/L after bio-chemical degradation of TMBR process ,the average removal rate is 95 .8% ,the average effluent COD is 45 mg/L after the NF/RO process and the average NH3 -N removal rate is 94 .9% .The concentration of NH3 -N is less than 25 mg/L after further separation and purification by the NF/RO process and it meets the landfill pollution control standard (GB 16889—2008 ) .The composite processing cost is 29 .5 yuan/m3 . |
