영문 초록

The anaerobic landfill leachate treatment can surmount dilution problem of high concentration landfill leachate, collect methane gas as byproduct, and treat low phosphate concentration leachate because of low nutrient salt requirement. The problems of conventional anaerobic treatment that are requirement of large reactor because of low microbial growth rate(HRT=20-30 days) and low volumetric loading rate(VLR=0.5-2.0 kg $COD/m^3\cdot day$) are able to surmount by introduction of high rate anaerobic treatment. In this study, the upflow blanket filter(UBF) which is high rate anaerobic process was applyed to the landfill leachate treatment. The acceptable volumetric loading rate and HRT were 18.23 kg $SCOD/m^3\cdot day$ and 13 hrs. SCOD removal rate was over 90% at VLR 18.23 kg $SCOD/m^3\cdot day$. The methane gas yield was $0.15 lCH_4/g$ SCOD added(at STP) at VLR 18.23 kg $SCOD/m^3\cdot day$. The solids accumulation yield was 0.40 g VSS/g COD removed.
