Abstract:

在(35±0.2)℃温度下,以餐厨垃圾和剩余污泥为原料,设置餐厨垃圾和剩余污泥混合比例(VS)分别为1:0、2:1、1:1、1:2和0:1,研究其单独消化与混合消化的系统性能、产甲烷潜力及脱氢酶活性和F420浓度变化。结果表明,混合消化提高了系统稳定性,与餐厨垃圾单独消化相比,添加剩余污泥能调节pH、氨氮浓度和VFA浓度,缩短产气周期;与剩余污泥单独消化相比,添加餐厨垃圾能显著提高沼气产量。混合比例为1:1组混合消化产甲烷潜力最佳,消化作用的协同效应最为明显,沼气和甲烷产量分别达358.2mL/gVS和224.1mL/gVS,较餐厨垃圾和污泥单独消化估计值分别提高了23.09%和36.80%。1:1混合消化组脱氢酶活性最高达437.33TFμg/(mL·h),比餐厨垃圾和剩余污泥单独消化分别提高93.60%和40.69%,辅酶F420浓度最高为1.718μmol/L,分别提高17.3%和100.7%。
