Description
好ましくは130〜220g/L、より好ましくは140〜220g/Lの値に適宜維持調整される。
・反応器の上流で計測されるTODが高すぎる場合:例えば、水または別の低濃度の廃水を用いて希釈する。
・反応器の上流で計測されるTODが低すぎる場合:例えば、有機廃棄物および/または無機廃棄物、または高濃度廃水を被処理廃水に加えることにより濃縮する。
本発明の方法の重要性を説明するために、以下に述べる様々な条件下で廃棄物の水熱酸化を行った。以下に、実施形態にかかる例1および例2の評価結果、および比較のための2つの例の評価結果を示す。
注入温度:250℃
T1=360℃
T2=450℃
T3=550℃
本例によると、廃棄物を効率的に変換でき、最終TODは30mg/Lであり、温度上昇を制御できた。
注入温度:340℃
T1=370℃
T2=450℃
T3=530℃
本例によると、廃棄物を効率的に変換でき、最終TODは110mg/Lであり、温度上昇を制御できた。
注入温度:250℃
T1=340℃
T2=350℃
T3=365℃
本例によると、TODが本発明による推奨の値より低く、最終TODは25g/L±5g/Lと高過ぎる値であり、このため廃棄物の十分な処理ができなかった(不合格となった廃棄物のTODは高過ぎた)。
注入温度:250℃
T1=360℃
T2=450℃
T3=580℃
本例4によると、TODが本発明による推奨の値より高く、最終TODは65g/L±5g/Lと高過ぎる値であった。TODが250g/Lの例は、温度が高過ぎる値となる限界により近く、反応器の劣化のリスクにつながる。
処理廃棄物は、大部分がアルコール誘導体および糖抽出物からなる醸造酒製造所からの廃棄物である。この廃棄物から水性媒体を作り、そのTODを、酸化反応器の入口において以下に示すTOD値、いわゆる「初期TOD」を得るために、反応器の上流で監視および制御した。混合物を反応器入口で予熱してから反応器に注入し、反応器の下流側に連続する3つの点において酸素を複数回にわたって分流した。媒体の温度は、(温度低下が全くない)上昇温度曲線に従って、最初の注入で温度T1まで、2回目の注入で温度T2まで、3回目の注入で温度T3まで上昇した。反応器の出口における流れのTOD、いわゆる「最終TOD」を計測した。
注入温度:200℃
T1=370℃
T2=450℃
T3=570℃
本実施形態によると、廃棄物を効率的に変換でき、最終TODは100mg/Lであり、温度上昇を制御できた。
