which could remove partial water and improve calorific value of municipal solid waste(MSW)
is generally required prior to its incineration or pyrolysis.The pre-treatment has significant impacts on the quality of waste disposal
energy recovery and pollutants emissions.In this study
the effects of pretreatment conditions of MSW on components of leachate and result of MFC treatment were investigated.It was found that the optimal pretreatment condition for MSW prolysis was:6 days stacking at 40℃.In that case
the weight of MSW lost by 30%
the concentrations of BOD and NH4+-N as well as the B/C value in the leachate were 20800 mg·L-1
1410 mg·L-1
and 0.32 respectively
and the content of nutrient materials was suitable for biochemical treatment.In addition
when MFC was employed for treating the leachate
the maximum output voltage could achieve 0.29 V
and the cell operated continuously 7 days
69.4% of BOD and 87.6% of NH4+-N in the leachate could be removed.
