(57) [Abstract] [Problem] Floats in water, sinks in water, stays on the ground surface, crosses soil, is easy to handle at contaminated sites, and a wide variety of microorganisms are established and are not decomposed by the action of microorganisms It is harmless even when discarded, immobilizes various microorganisms, has good water absorption and excellent transpiration, is chemically stable, has excellent heat and heat insulation properties, is easy to obtain, is inexpensive, and has a large amount. It is a natural material that exists in Provided is a biopurification material as a carrier for immobilizing microorganisms useful for environmental purification, which is an urgent issue, and a method for producing the same. The method for producing a biopurification material is useful for biopurification as a granule / molded product of powdered, granular, massive or granulated pearlite or shirasu balloon and rhyolite pumice. It is a porous material that is immersed, adsorbed or adhered to a suspension of various microorganisms, air-dried, and used as a biopurification material. It is disposable and harmless. |
