Title:
NITRATE-REMOVING BIOREACTOR, METHOD FOR FORMING NITRATE-REMOVING BIOFILM, AND NITRATE-REMOVING METHOD
Document Type and Number:
WIPO Patent Application WO/2010/067788
Kind Code:
A1
Abstract:
Disclosed is a bioreactor which is capable of efficiently removing nitrate ions. A nitrate-removing bioreactor (1) comprises a reaction container (2) and an introduction part (3) for introducing a fermentation source (S) into the reaction container (2), said introduction part (3) being provided onto the upper part of the reaction container (2). The reaction container (2) produces an organic acid (A) by anaerobic fermentation of the fermentation source (S), and is partially provided with a structure (4) through which the organic acid (A) can permeate. A ceramic material can be used for the organic acid-permeable structure (4).
