Abstract
Description
数式1 : φ = (σ・d) / (p・s)
φは透気係数(L・cm/分・kP・cm2)、σは流量(L/分)、pは入出の差圧(kP)、sは断面積(cm2)、dは長さ(cm)点にある。
図1には、クローズドタイプ(「被覆型」とも呼ばれる。)の管理型最終処分場10の構造が示されている。管理型最終処分場10(以下、単に「最終処分場10」と記す場合もある。)は、廃棄物の処理及び清掃に関する法律で定められる構造基準と維持管理基準に基づいて設置及び運営され、同法に定められた廃棄物の区分に従って埋立処分される。
φは透気係数(L・cm/分・kP・cm2)、σは流量(L/分)、pは入出の差圧(kP)、sは断面積(cm2)、dは長さ(cm)
上述した実施形態では、通気性改質材混合ステップで通気性改質材が混合された特定有機性廃棄物を最終処分場10に埋設した後に通気ステップが実行される態様を説明したが、通気性改質材が混合された特定有機性廃棄物を最終処分場10に埋設する前に通気ステップが実行される態様を採用することも可能である。
