- 飽和難透気透水層のうち、汚染物質で汚染されている汚染領域又は該汚染領域の上方に位置し前記汚染物質を連行した空気が浮上通過する飽和透水層内の通過領域の少なくともいずれかに微生物活性を高めるための栄養塩が添加された洗浄水を通水するとともに、前記汚染領域に高圧空気を間欠的に送り込み該高圧空気の間欠圧入によって前記汚染領域内の土粒子に振動を付与し、前記汚染物質が連行された前記洗浄水を揚水して浄化処理を行うとともに、間欠圧入された空気に前記汚染物質を連行させながら該空気を気泡として前記飽和難透気透水層の上方に拡がる不飽和透気層まで前記通過領域を介して浮上させ、前記汚染物質を前記空気とともに吸引して浄化処理を行うことを特徴とする難透気透水性汚染土壌の浄化方法。
- 飽和難透気透水層のうち、汚染物質で汚染されている汚染領域又は該汚染領域の上方に位置し前記汚染物質を連行した空気が浮上通過する飽和透水層内の通過領域の少なくともいずれかを挟む対向位置に埋設された注水井戸及び揚水井戸と、前記注水井戸に連通接続され微生物活性を高めるための栄養塩が添加された洗浄水を貯留する貯水槽と、前記揚水井戸内に設置された揚水ポンプに連通接続され該揚水井戸を介して揚水された水を浄化する水処理設備とを備えた難透気透水性汚染土壌の浄化システムであって、
前記汚染領域に高圧空気を間欠的に送り込み該高圧空気の間欠圧入によって前記汚染領域内の土粒子に振動を付与する高圧空気圧入機構と、間欠圧入された空気に連行され前記飽和難透気透水層の上方に拡がる不飽和透気層まで前記通過領域を介して浮上した汚染物質を気泡状の該空気とともに吸引して浄化するガス処理設備とを備え、前記高圧空気圧入機構を、高圧空気吐出口が前記飽和難透気透水層の汚染領域に位置するように埋設される圧入管と、圧力容器及び空気タンクを介して該圧入管に接続されたエアコンプレッサーとから構成したことを特徴とする難透気透水性汚染土壌の浄化システム。
