Abstract
【課題】 粘性土に混入している汚染物質である揮発性有機化合物を確実かつ効率的に除去する。
【解決手段】本発明に係る汚染粘性土の浄化方法においては、まず、揮発性有機化合物で汚染された粘性土に吸水材としてのパーライトを添加して1次処理対象土とする(ステップ101)。次に、1次処理対象土を攪拌混合することで1次処理対象土に攪拌力を作用させ、これを2次処理対象土とする(ステップ102)。次に、攪拌混合された2次処理対象土を処理用ベッド2の上に敷設し、次いで、該2次処理対象土に通気処理を行うことにより、2次処理対象土に含まれる揮発性有機化合物を空気連行によって除去する(ステップ103)。
