Patent abstract
There is provided a nitrogen treating method capable of treating nitrogen compounds efficiently. The method is a nitrogen treating method of treating nitrogen compounds in for-treatment water by electrolysis and performs a first treating step of producing ammonia from the nitrogen compounds in the for-treatment water by electrolysis using a cathode and an anode between which a cation exchange film is interposed so as to define a cathode reaction region and an anode reaction region, and a second treating step of removing the ammonia in the for-treatment water treated in the cathode reaction region by the first treating step.
