PURIFICATION COMPOSITION FOR SOIL AND GROUND WATER AND PURIFICATION METHOD OF SOIL AND GROUND WATER USING THE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a purification composition for soil and ground water that secures a sufficient amount of oxygen generation and the stable purification rate of oils which is not influenced by the microbiological amount in situ, and to provide a purification method of soil and ground water using the composition.

SOLUTION: The purification composition is exemplarily constituted of hydrogen peroxide added calcium hydroxide, an enzyme and 30% or less of a surfactant based on the total weight. The surfactant is a nonionic surfactant. Lipase is used as an enzyme and the lipase is carried on an inorganic material.
