RECYCLING SOIL AND RECYCLING SOIL MANUFACTURING METHOD, UTILIZING ORGANIC AND INORGANIC SLUGE

摘要

PURPOSE: A manufacturing method of a recycling embankment material using organic and inorganic sludge is provided to manufacture the recycling embankment material from the organic and inorganic sludge by preparing a reactant and an adsorbent by utilizing an industrial byproduct, and using the prepared reactant and adsorbent. CONSTITUTION: A manufacturing method of a recycling embankment material using organic and inorganic sludge comprises the following steps. KR(Kanvara Reactor) dusts(10) containing 50-60 wt% of CaO, calcium oxide(20) containing 75-95 wt% of CaO, and a lava-based soil powder(30) at a size of 200-400 mesh are mixed to prepare a reactant(40) that is highly reactive in an exothermic reaction and an ammonia gas and heavy metal ionization reaction(S1). An adsorbent(70) is prepared by mixing a diatomaceous earth powder(50) at a size of 200-400 mesh and paper mill sludge ash(60) containing 40-50 wt% of CaO(S2). An organic and inorganic sludge in a form of particles is manufactured by mixing the reactant and adsorbent to an organic and inorganic sludge(80) with 30-85 wt% of water content(S3). Then, air is blown into the particles of the organic and inorganic sludge mixture to solidify the surface of the product particles, oxidize the particles so as to have the same color with soil, and thus a recycling embankment material(90) is manufactured(S4).
