Research of treatment of landfill leachate thro ugh two-stage SBRs following absorption and coagulation with PAC
两级SBR-PAC吸附混凝法处理垃圾渗滤液的研究

Treatment of landfill leachate is a focus of researcher's attention as well as a difficult problem in field of wastewater treatment. The landfill leachate(COD Cr 1500 4500 mg/L,NH 4 + N 795 1550 mg/L,pH 8.0 9.0) from a garbage landfill disposal plant in Hangzhou was handled by recycle and two stage SBR with absorption and coagulation of PAC as a post treatment. The effluent COD Cr concentration was less than 300 mg/L and NH 4 + N concentration was less than 20 mg/L.
