摘要
为探索外源物对厨余垃圾干式厌氧消化系统中油脂抑制作用的缓解效果,选取了硫酸亚铁和氯化钙用作外源物,评估添加外源物后含油脂厨余垃圾厌氧消化系统的工艺运行情况,并对添加后的沼气产量、甲烷体积分数、pH、FOS/TAC和挥发性有机酸成分浓度等工艺指标进行测试与分析。研究结果表明:硫酸亚铁和氯化钙均具有缓解油脂对干式厌氧消化工艺运行的抑制作用,其中硫酸亚铁的缓解效果更佳。
In order to explore the alleviating effect of additives on lipid inhibition in the dry anaerobic digestion system of kitchen waste,this study took ferrous sulfate and calcium chloride as additives,evaluated the process operation of the anaerobic digestion system of lipid-containing kitchen waste after the addition of the additives,and then analyzed the gas production,methane volume fraction,pH value,FOS/TAC ratio and the concentration of volatile organic acids in the anaerobic digestion system of lipid-containing kitchen waste.The results showed that both ferrous sulfate and calcium chloride could alleviate the inhibition of lipid on dry anaerobic fermentation,wherein the alleviating effect of ferrous sulfate was better.
