在实验室研究城市生物有机垃圾好氧和厌氧处理的生物降解能力,分析反应物质的输入和输出,研究好氧堆肥及厌氧消化反应过程中的参数变化,并得出相关结论:(1)堆肥过程中,箱体温度可以达到55℃以上,并持续3 d以上,达到无害化处理;堆肥过程中物料的pH值先降低后升高,最终稳定呈弱碱性,弱碱性pH值有利于提高土壤中阳离子交换能力,提高土壤肥力;(2)源分类后城市生物有机垃圾在堆肥处理的第一周减量化最明显,为21.23%,明显高于后2周,好氧生物降解率平均为63.20%;(3)沈阳市源分类生物有机垃圾实验室沼气产量为619 m3/(t VS),其中甲烷浓度平均为54.36%,沼气生物能为19.52 MJ/m3,厌氧生物降解率为70.14%.
