METHOD FOR PHOSPHORUS ELUTION-PREVENTION TREATMENT OF BEER LEES BRIQUETTE, PHOSPHORUS ELUTION-PREVENTION- TREATED BEER LEES BRIQUETTE, AND WATER-PURIFYING MATERIAL MADE OF BEER LEES BRIQUETTE

摘要

PROBLEM TO BE SOLVED: To provide a method for a phosphorus elution-prevention treatment of a beer lees briquette, a phosphorus elution-prevention-treated beer lees briquette, and a water-purifying material made of the beer lees briquette. ;SOLUTION: The method for a phosphorus elution-prevention treatment of a carbonized product (beer lees briquette), obtained by baking a molded product which is prepared by dehydrating, drying, heating and compressing beer lees, comprises adding, before molding, a substance (for example, a calcium compound such as hydrated lime, calcium carbonate and the like) which reacts with phosphor to form a hardly water-soluble substance (for example, calcium phosphate).;COPYRIGHT: (C)2003,JPO
