NITRIC ACID REMOVAL BIOREACTOR, METHOD FOR GENERATING NITRIC ACID REMOVAL BIOFILM, AND METHOD FOR REMOVING NITRIC ACID

摘要

PROBLEM TO BE SOLVED: To provide a bioreactor capable of efficiently removing a nitric acid ion.

SOLUTION: A nitric acid removal bioreactor 1 is constructed by including a reactor 2 and an input part 3 which is provided thereon to input a fermentation source S in the reactor 2. The reactor 2 makes the fermentation source S anaerobically ferment to generate organic acids A, wherein some area is provided with a structure 4 through which the organic acids A can be permeated. The ceramic materials can be used as the structure 4 of organic acid permeation.
