چکیده انگلیسی
Laboratory-scale experiments were carried out in completely mixed reactors, 1Â L capacity. Optimal conditions for COD solubilization in the first step of pretreatment were 62.0Â mEq Ca(OH)2/L for 6.0Â h. Under these conditions, 11.5% of the COD was solubilized. The anaerobic digestion efficiency of the OFMSW, with and without pretreatment, was evaluated. The highest methane yield under anaerobic digestion of the pretreated waste was 0.15Â m3Â CH4/kg volatile solids (VS), 172.0% of the control. Under that condition the soluble COD and VS removal were 93.0% and 94.0%, respectively. The results have shown that chemical pretreatment with lime, followed by anaerobic digestion, provides the best results for stabilizing the OFMSW.
