Abstract: In order to reduce the operation cost of composting process with forced air ventilation, this study investigated the effect of intermittent ventilation on composting. Experiments with a small-scale reactor system were conducted for several combinations of ventilation rate, ratio of ventilation period and resting period, and cycling time of intermittent ventilation. The experiment results demonstrated that a relatively higher ventilation rate and specific combination of ventilation/resting ratio could provide more effective composting than continuous ventilation. The tendency of the results seemed reasonable from our previous analyses on composting with continuous ventilation.
コンポスト化プロセスの省エネ化によるコストの低減を目指し、小容積堆肥化実験装置を用いた間欠通気の効果を検証した。コンポスト化の進行状況に影響を与える因子としては、通気中の通気量、通気時間と休止時間との比、および間欠1サイクルの所要時間などが主要なものと考え、これらを変化させて実験した。 その結果、改善効果を得るための適正間欠通気条件の選択にとって示唆的な知見が得られた。また結果の動向は連続通気反応解析の知見ともほぼ整合するものであった。
