Denitrification method, denitrifying sulfur-oxidizing bacterium fixed carrier, and method for producing denitrifying sulfur-oxidizing bacterium fixed carrier

摘要

PROBLEM TO BE SOLVED: To use molten sulfur as a denitrifying sulfur oxidation bacterium immobilized carrier. SOLUTION: This denitrifying sulfur oxidation bacterium-immobilized carrier is brought into contact with a solution to be treated under an anaerobic condition or under an oxygen free condition in a denitrogenation treatment and composed of simple substance sulfur. At least the surface part S to be brought into contact with the solution to be treated is made porous by supporting holes H having =100 m minor axes.
