FILTER MEDIUM FOR SOIL IMPROVEMENT, METHOD FOR MANUFACTURING THE FILTER MEDIUM FOR SOIL IMPROVEMENT, AND METHOD OF SOIL IMPROVEMENT USING THE FILTER MEDIUM FOR SOIL IMPROVEMENT

摘要

PROBLEM TO BE SOLVED: To form a filter medium for soil improvement by utilizing feces and urine excreted by livestock and to provide processes for forming the filter medium and usage thereof.;SOLUTION: The filter medium for soil improvement comprises a filter medium of powder lumps of the livestock feces and urine and a filter medium of powder lumps of natural ores. The filter medium of the powder lumps of the livestock feces and urine are obtained by applying a glaze having natural ore powder as a principal raw material to a base material part formed by firing bottom ash obtained by burning the feces and urine of livestock. A vibration spectrum of the glaze part has physical properties corresponding to an absorption spectrum of water contained in the soil, thereby achieving improvement. The filter medium of powder lumps of natural ores is obtained by applying the same glaze to a base material part formed by firing stone powder of the natural ores. The vibration spectrum of the glaze part has physical properties corresponding to the absorption spectrum of water in contact therewith, thereby achieving improvement.;COPYRIGHT: (C)2011,JPO&INPIT
