IMMOBILIZED MICROORGANISM CARRIER AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an immobilized microorganism carrier having a large carrier size and capable of developing a high treatment capacity regardless of a fluidized or fixed bed type of a biological reactor.

SOLUTION: The carrier 10 has an outer surface shape formed from a single planar part 12 and a single curved part 14 or a plurality of curved parts 14A and 14B, for example, like a semispherical body. Specific gravity difference is formed in the interior 16 of the carrier and a single or one or more recessed sump parts 18 are formed to the planar part 12.
