Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a purification facilitation material capable of conducting a purification treatment by bioremediation of oil contaminated soil in a relatively short term even when the soil is acidic and has low air permeability such as Kunigami-maaji and a purification treatment method using the same.SOLUTION: There are provided a purification facilitation material for being mixed with oil contaminated soil during microorganism purification of the soil, the purification facilitation material being Ryukyu limestone or a fracture article thereof, and a purification treatment method for the oil contaminated soil by mixing the Ryukyu limestone or the fracture article with the oil contaminated soil in a weight ratio of 10 to 30%.SELECTED DRAWING: Figure 9 【課題】本発明は、国頭マージのように酸性で通気性が低い土壌でも、油汚染土壌に対するバイオレメディエーションによる浄化処理を、比較的短期間に行うことができる浄化促進材及びこれを用いた浄化処理方法を提供することを課題とする。【解決手段】本発明は、油汚染土壌に対する微生物浄化に際して土壌に混合する浄化促進材が、琉球石灰岩またはその破砕物であることを特徴とする油汚染土壌の浄化促進材であり、これを油汚染土壌に対して、琉球石灰岩またはその破砕物を、重量比10〜30％混合させることを特徴とする油汚染土壌の浄化処理方法である。【選択図】図９
