The present invention discloses a porous granule composite material with absorption and reaction capacities and a preparation technology thereof. The porous granule composite material is a spherical porous granule material containing quicklime and comprises the components of the quicklime, attapulgite, bentonite, certain quantity of slat additives and active carbon used as pore-forming agent to be calcined in high temperature to obtain the porous granule composite material. The porous granule composite material has large specific surface area and through holes widely distributed on the specific surface; when being contacted with liquid material, the porous granule composite material has high reaction speed and reaction degree; the porous granule composite material also has the effect of obstructing a great deal of fluid contamination and the effect of preventing harmful substance from seeping into the environmental soil. The granule material can be used for the occasion under the requirement of fast processing acid or alkali liquid contamination.
