Description
本出願は、2005年2月28日付けで出願した日本国特願2005―54140号に基づく優先権を主張し、その内容を援用するものである。
また、本発明における発酵助材は植物性の繊維を多く含むため、発酵助材を添加することにより、土壌の通気性が向上し、さらに強熱減量も増加している。その結果、土壌改善効果が見られた。このような土壌の通気性を表す湿潤密度(g/cm3)及び土壌粒子間の間隙率(%)を表1に示す。他方、土壌中に含まれる有機物量の目安となる強熱減量(%)を表2に示す。
Claims (5)
- 有機汚染物質に汚染された汚染土壌に通気し、前記有機汚染物質の分解性能を備えた好気性微生物を活性化させて、前記有機汚染物質を発酵分解することにより前記汚染土壌を浄化する汚染土壌の浄化方法であって、
糟糠類を含有する発酵助材の添加割合毎に求めた、気温と、前記添加割合の発酵助剤を添加した場合における土壌温度との関係に基づき、前記関係において、気温に対応する土壌温度が所望の温度となるような添加割合を、前記汚染土壌に対する前記発酵助材の添加割合として決定し、
前記決定した添加割合で前記発酵助材を前記汚染土壌に対して添加し、この汚染土壌の温度を前記所望の温度が維持できるように通気量を制御することを特徴とする汚染土壌の浄化方法。 - 前記発酵助材を、前記汚染土壌の質量に対して0.2〜5質量%添加することを特徴とする請求項1に記載の汚染土壌の浄化方法。
- 前記通気量の制御を、吸気と送気を組合せて行うことを特徴とする請求項1又は2に記載の汚染土壌の浄化方法。
- 前記通気量の制御において、通気を一時的に停止することを特徴とする請求項1から3のいずれかに記載の汚染土壌の浄化方法。
- 前記有機汚染物質の易分解性成分が分解された後に、前記通気量を減少させることを特徴とする請求項1から4のいずれかに記載の汚染土壌の浄化方法。
