Description
処理すべき下水汚泥1000重量部を発酵槽内に投入し、これに水分調整材を加えて含水率を45〜55%となし、前記発酵資材1〜2重量部を加えて混合し、
続いて、発酵槽内の温度を60℃〜200℃に加温し、発酵槽内に空気を注入し、発酵槽内を連続的に攪拌することにより下水汚泥を発酵処理することを特徴とする下水汚泥の処理方法(請求項1)。
請求項1の発明において製造される下水汚泥処理用の発酵資材を下水汚泥に加え、60℃〜200℃の温度にて発酵処理することにより、下水汚泥中の重金属、ダイオキシン類等の有害物が分解される。
麦飯石は多孔性の多元素物質であり、麦飯石の粉末を発酵槽内に投入して処理物に混入したときには、処理物にバクテリアが好ましく吸着し、発酵が著しく促進される。
除湿機は発酵槽内の結露を防止する。
酵母菌、セルロース分解菌、窒素固定菌、乳酸菌、糸状菌(芳香族化合物分解菌)、マンガン還元菌(クロカビ属群−原生担子菌類)、マンガン酸化菌(有機栄養菌)、アンモニア酸化菌(亜硝酸菌)、放線菌(キチン分解菌)、硝酸菌(硝化生成細菌)、硫黄細菌(硫化水素を水素供与体として利用する細菌群)、メタン酸化菌、セルロース放線菌、セルロース糸状菌、納豆菌、リグニン分解菌、鉄酸化菌、鉄還元菌、硫酸還元菌、酢酸菌、バチルス属(Bacillus sp.)、スポロサルシナ属(Sporosarcina sp.)、ペニバチルス属( Paenibacillus sp.)、オーシャノバチルス属(Oceanobacillus sp.)。
Claims (3)
- 配合菌数の割合が好気性菌群55%と嫌気性菌群45%とよりなる有効微生物群をオカラに混合し、40℃〜200℃の温度にて24時間〜72時間一次発酵させ、更に、これに配合菌数の割合が好気性菌群55%と嫌気性菌群45%とよりなる有効微生物群を混合し、40℃〜200℃の温度にて24時間〜48時間二次発酵させることにより下水汚泥処理用の発酵資材を製造し、
処理すべき下水汚泥1000重量部を発酵槽内に投入し、これに水分調整材を加えて含水率を45〜55%となし、前記発酵資材1〜2重量部を加えて混合し、
続いて、発酵槽内の温度を60℃〜200℃に加温し、発酵槽内に空気を注入し、発酵槽内を連続的に攪拌することにより下水汚泥を発酵処理することを特徴とする下水汚泥の処理方法。 - 前記発酵槽内に発酵促進剤として麦飯石の粉末を投入することを特徴とする請求項1に記載の下水汚泥の処理方法。
- 前記発酵槽には除湿機を備えさせたことを特徴とする請求項1又は2に記載の下水汚泥の処理方法。
