High-chlorine high-ammonia-nitrogen wastewater treatment device with three-dimensional electrode

Abstract

The invention provides a high-chlorine high-ammonia-nitrogen wastewater treatment device with a three-dimensional electrode, which comprises an electrolytic tank, an anode electrode and a cathode electrode; the anode electrode comprises a plurality of anode plates arranged in parallel, the cathode electrode comprises a plurality of cathode plates arranged in parallel, the anode plates are insertedinto the cathode plates and arranged in a staggered manner, and the cathode plates are arranged in a staggered manner. Activated carbon and insulating particles are filled between the anode plate andthe cathode plate according to the volume ratio of 1: 1 to serve as a bipolar third electrode, openings between the anode plate and the cathode plate are sealed through insulating separation nets, and an ultrasonic rod is arranged in the electrolytic tank. The bipolar third electrode can adsorb organic matters, and is not influenced by the adsorption saturation amount in an adsorption and degradation circulation mode; in addition, the effective reaction surface area of the electrolytic cell in unit volume is increased, the mass transfer effect is enhanced, and the wastewater treatment efficiency is improved, so that the generation of short-circuit current is reduced, and the current efficiency is improved. Besides, by arranging an ultrasonic rod, the utilization rate of active groups generated by electrolysis is increased through the ultrasonic effect, and the wastewater treatment efficiency is improved.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a high chlorine and high ammonia nitrogen waste water treatment device with three-dimensional electrodes. Background technique [0002] Ammonia nitrogen is one of the important factors causing eutrophication of water bodies. With the increasing of wastewater discharge standards, the requirements and demands for removing residual ammonia nitrogen in wastewater are getting higher and higher. There are many ways to remove ammonia nitrogen from industrial wastewater, and the breakpoint chlorine addition method is often used because of its simplicity. In the prior art, since the liquid contains a lot of ammonia nitrogen components, it is more difficult to manually handle, such as the phenomenon of unpleasant smell and high odor concentration. [0003] Electrocatalytic oxidation technology degrades organic pollutants in wastewater by generating strong oxidizing active groups such ...
