Description
本発明に係る有機汚染物質の浄化方法においては、過酸化水素および鉄系触媒(金属鉄)を添加した条件下で、高濃度の有機汚染物質を分解後、低コストで浄化可能な過硫酸塩を注入拡散させることで、高濃度の汚染に対しても短期間で低コストに浄化が可能になる。
TCE10mg/L、シス-1,2-ジクロロエチレン3mg/Lで汚染された粘土層に対して、土中混練機を用いて、過酸化水素とリン酸を混合した溶液と鉄系触媒を汚染土壌に添加、混練した。その後、充分に時間を経過した40日後に中間浄化確認ボーリングを行い、汚染濃度の確認を行った。このフェントン酸化の結果、TCEに関しては環境基準値以下まで低減していたが、シス-1,2-ジクロロエチレンは環境基準値以上であった(図1)。
Claims (4)
- 有機汚染物質に汚染された汚染物を汚染原位置で浄化するに当たり、攪拌翼を有する混練機で過酸化水素および鉄系触媒としての金属鉄を汚染物に添加、混練した後に、井戸から過硫酸塩を注入し汚染物に接触させることを特徴とする有機汚染物質の浄化方法。
- 前記過酸化水素および前記鉄系触媒としての金属鉄を汚染物に添加、混練してから1日以上経過した後に、前記過硫酸塩を注入し汚染物に接触させる、請求項1に記載の有機汚染物質の浄化方法。
- 汚染物に対して、前記過酸化水素を0.1〜5%の濃度、前記鉄系触媒を鉄として0.5〜10%の濃度でそれぞれ添加し、前記過硫酸塩を0.1〜5%の濃度で注入する、請求項1または2に記載の有機汚染物質の浄化方法。
- 前記汚染物の汚染濃度が、環境基準の十倍を上回る高濃度である、請求項1〜3のいずれかに記載の有機汚染物質の浄化方法。
