ELECTROLYTIC TREATMENT METHOD OF NITROGEN COMPOUND-CONTAINING WASTE WATER

摘要

PROBLEM TO BE SOLVED: To provide an electrolytic treatment method of nitrogen compound-containing waste water capable of obtaining water treated of excellent water quality by reducing the production amount of a persistent by-product product and odor component in electrolytic treatment of nitrogen compound-containing waste water containing ammonia or hydrazine.;SOLUTION: The waste water treatment method decomposes nitrogen compound by electrolytic treating waste water containing nitrogen compound containing at least ammonia or hydrazine in an electrolytic tank. In the method, the concentration of the free residual chlorine in the waste water to be electrolyzed is adjusted to a concentration obtained by adding six-times of the ammonium-nitrogen concentration in the waste water to four-times of the hydrazine-nitrogen concentration in the waste water, then the waste water is electrolyzed.;COPYRIGHT: (C)2005,JPO&NCIPI
