Document Type and Number:
Japanese Patent JP3641749
Kind Code:

Abstract:
PROBLEM TO BE SOLVED: To provide a method for clarifying soil/ground water, which efficiently clarifies contaminated soil and contaminated ground water by rapidly penetrating contaminant clarifying agents over a wide range into the contaminated soil and contaminated ground water, rapidly and completely clarifies the contaminated soil and contaminated ground water by making combination use of supplying of the clarifying water and pumping up and clarifying of the contaminated ground water from a well hole and facilitates work by eliminating the need for removal/withdrawal of used apparatus and components.
SOLUTION: A plurality of three-dimensional gap structures formed by entangling resin wire bodies with each other and laminating the bodies to a hollow cylindrical form are embedded into the ground and the contaminants clarifying agents consisting essentially of aerobic bacteria are supplied through the three-dimensional gap structures into the soil and/or the ground water.
