Description
前記メタン発酵槽の外部に接続された循環経路によって、前記メタン発酵槽内の発酵液の一部を循環させ、この循環経路の途中に熱交換器を設け、
前記熱交換器の加熱側の熱媒体の温度を55〜60℃とし、
前記メタン発酵槽内の温度が53〜57℃となるように、前記発酵液の循環流量を制御することを特徴とする。
また、発酵液を加熱する温水等の熱媒体の温度が60℃以下であるので、熱交換器の滞留部でも、菌を含む発酵液の温度が60℃を超えることがない。また、メタン発酵槽の温度が高く、循環ポンプの流量が少ない条件でも、菌を含む発酵液の温度が60℃を超えることがない。このため、メタン発酵槽内の温度を、高温メタン発酵の最適温度である53〜57℃という狭い範囲内でも安定して温度制御でき、菌の活性を最適な状態に維持でき、充分なスラリー処理量を確保することができる。
(X:菌体数、X0:初期菌体数、t:時間)
ここで、kdは菌の死滅速度である。この(1)式を用いて、まず異なる温度における死滅速度kdがどのように変化するかを測定する。
