Description
本発明によれば、下水処理場へ流入したディスポーザー残滓をスクリーンや遠心分離機などにより物理的に分離し、簡単な設備を追加するだけで、ディスポーザー残滓を短期間に、安価に、簡便・容易に、衛生的に、しかも効率的に、無臭醗酵分解処理することが可能です。このように、本発明の採用により、下水処理場の処理能力の問題の一つは、解決出来ます。その結果、もし、ディスポーザーが各家庭で使えるようになれば、家庭での生ゴミ処理は、簡単になり、生ゴミの悪臭問題も無くなり、収集・運搬の手間もなくなり、既存の下水道の利用効率(糞尿・汚水+生ゴミ処理と多機能化するため)を高め、自燃しない生ゴミの焼却処理に大金を払う必要もなくなります。従って、本発明の効果は、経済上の効果だけではなく、わが国、特に大都市での家庭生活の利便性の向上、衛生上の波及効果などを考えると、その効果は、計り知れないものがあります。
B:家畜糞などの易分解性のバイオマス(有機質物)。種菌母材(菌床)を製造する主原料。
C:籾殻などの難分解性のバイオマス(有機質物)。種菌母材(菌床)を製造する副原料。
X:種菌母材(菌床)=醗酵分解処理に必要な菌体群を、高密度に扶植・包蔵する担体・菌床。
Y:分解対象のバイオマス(有機質物)。(形状は、大きな牛・馬などの個体そのものから、微細な粉体、獣脂、油脂、魚油、血液まで、種々多様。)
Claims (3)
- 穀物由来の乳酸菌などの常在微生物群を中心に、個々の単一の純菌として分離・使用するのではなく、通常の環境中に存在する、あるがままの常在菌群として捉え、活用することを特徴とし、厳密に管理された高価な無菌室内での作業を必要としない、通常の注意レベルの作業により、屋内、屋外又は開放建屋内などの開放空間でも、容易に実施できる事を特徴とし、以下に示す2つの工程により構成され、分解対象のバイオマス(有機質物) 1倍量を体積量3乃至10倍量の種菌母材(菌床)により、無臭醗酵分解する事を特徴とするバイオマス(有機質物)無臭醗酵分解処理方法。
工程1:乳酸、クエン酸又は乳酸菌を含むPH4以下の醗酵分解促進液を用いて、弱酸性の醗酵環境を創出し、腐敗菌や雑菌の活動を抑制し、腐敗菌や雑菌の活動に起因する悪臭の発生を大幅に抑制しつつ、分解対象のバイオマス(有機質物)を特異・選択的に醗酵分解する菌体群を、高密度に、増殖・保持・包蔵する事を特徴とする前記種菌母材(菌床)の製造工程
工程2:分解対象のバイオマス(有機質物)1倍量に対して、適量の乳酸、クエン酸又は 乳酸菌を含むPH4以下の前記醗酵分解促進液を、分解対象バイオマス(有機質物)に散 布し、弱酸性に変え、体積量3乃至10倍量の前記種菌母材(菌床)を用いて、分解対象バイオマス(有機質物)を短期間に、悪臭の発生を大幅に抑制しつつ、分子レベルに分解する事を特徴とするバイオマス(有機質物)無臭醗酵分解処理工程 - 前記工程1は、家畜糞などの易分解性有機質物(主原料)に、乳酸、クエン酸又は乳酸菌 を含むPH4以下の前記醗酵分解促進液を撒布した後、撹拌・混合し、易分解性有機質物(主原料)を弱酸性に変え、更に、籾殻などの難分解性有機質物(副原料)を加え、撹拌・堆積・静置し、弱酸性の醗酵環境を創出し、悪臭の発生を大幅に抑制しつつ、嫌気醗酵、好気醗酵(1次醗酵)、熟成(2次醗酵)を、順次、連鎖的に発現・継続させる事を特徴とし、同時に、分解対象のバイオマス(有機質物)を特異・選択的に醗酵分解する菌体群を、高密度に、増殖・保持・包蔵する事を特徴とする種菌母材(菌床)の製造方法であ る請求項1記載のバイオマス(有機質物)無臭醗酵分解処理方法。
- 前記工程2は、分解対象のバイオマス(有機質物)1倍量に、適量の乳酸、クエン酸又は 乳酸菌を含むPH4以下の前記醗酵分解促進液を撒布・撹拌し、弱酸性の醗酵環境を創出した後、このバイオマス(有機質物)を堆積し、体積量3乃至10倍量の前記種菌母材(菌床)で、包むように覆い、静置し、悪臭の発生を抑制しつつ、嫌気醗酵させ、嫌気醗酵終了後、バイオマス(有機質物)と種菌母材(菌床)とを撹拌・混合し、十分曝気した後、堆積・静置し、好気醗酵を発現・促進させ、次に、バイオマス(有機質物)の分解処理が完了するまで、この操作を繰り返し、悪臭の発生を大幅に抑制しつつ、極めて短期間にバイオマス(有機質物)を醗酵分解処理する事を特徴とする請求項1記載のバイオマス(有機質物)無臭醗酵分解処理方法
