内容記述 0.6m^3容大型発酵槽にて馴養したスラッジに生甘藷アルコール蒸留廃液を混合しpH7.5,37℃でメタン発酵を行い, ガス生成経過, 発生ガス量及び発生ガス中のメタン含量等について調べた。蒸留廃液を7日間メタン発酵して得られる総発生ガス量は廃液の有機物kg当たり819ℓで, その90%は発酵5日間で発生した。発生ガス中のメタン含量は69.8%に達した。発酵1日目から有機酸(酢酸, プロピオン酸等)の蓄積がみられたが, 発酵3日目以後は減少した。廃液を5日毎, 半連続的に添加した発酵で発生するガス量は廃液の有機物kg当たり860ℓで, メタン含量は70.6%であった。廃液を連日添加する連続発酵における最大ガス発生量は有機物kg当たり889ℓであった。
