Abstract

The invention discloses an ammonia nitrogen wastewater treating method and device and relates to the technical field of wastewater treatment. The ammonia nitrogen wastewater treating method comprisesthe steps that pH value regulation is performed, wherein the pH value of ammonia nitrogen wastewater in a pH value regulation device is regulated; electrolytic reaction is performed, wherein the ammonia nitrogen wastewater undergoing the pH value regulation step is introduced into an electrolytic oxidation device, and electrolytic reaction is performed; tail gas collection is performed, wherein the gas produced in the electrolytic reaction is introduced into a tail gas collecting device. The invention also provides the ammonia nitrogen wastewater treating device for carrying out the ammonia nitrogen wastewater treating method. By adopting the ammonia nitrogen wastewater treating method and the ammonia nitrogen wastewater treating device, the ammonia nitrogen in wastewater is directly degraded through electrolytic oxidation effect, the removal rate of ammonia nitrogen can be 99% or above, other agents are not needed, and the cost of the agents is greatly saved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a method and device for treating ammonia nitrogen wastewater. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are set forth in the claims and detailed description. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Ammonia nitrogen wastewater mainly comes from chemical fertilizers, coking, petrochemicals, pharmaceuticals, food, landfills, etc. A large amount of ammonia nitrogen wastewater discharges into water bodies not only causes eutrophication of water bodies, causes water body black and smelly, but also increases the difficulty and cost of water supply treatment, and even affects Harmful to people and organisms. [0004] At present, methods such as air stripping, breakpoint chlorination and MAP chemical precipitation are mainly used ...
