Electrocatalytic oxidation device

Abstract

The invention provides an electrocatalytic oxidation device. The device comprises a tank body, a cathode electrode and an anode electrode are arranged in the tank body, and a power supply is arrangedoutside the tank body; an air outlet is formed in the top of the side surface of the tank body and is connected with an air outlet pipeline, and the tail end of the air outlet pipeline is connected with an exhaust fan; a push plate is arranged at the end, away from the air outlet, in the tank body, the bottom of the push plate is higher than the upper surfaces of the cathode electrode and the anode electrode, a bottom plate is vertically and slidably connected to the push plate, the upper surface of the bottom plate is a sliding slope inclining downwards from the side close to the push plate,and a limiting block for limiting falling of the bottom plate is arranged at the bottom of the push plate; a driving mechanism for driving the push plate to move towards the air outlet is mounted on the tank body, a guide block is fixed at one end, close to the air outlet, of the inner side of the tank body and provided with a guide slope obliquely extending downwards from the bottom of the air outlet, and the lowermost end of the guide slope is located below the limiting block; and the lower surface of the air outlet pipeline is connected with a discharging pipe, and the discharging pipe is sleeved with a material receiving box which seals a pipe opening of the discharging pipe. Dross generated in the electrolysis process can be rapidly removed.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to an electrocatalytic oxidation device. Background technique [0002] 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 People and organisms produce toxic effects. The treatment processes for ammonia nitrogen wastewater mainly include zeolite deammonization method, MAP precipitation method, chemical oxidation method, etc., and then electrocatalytic oxidation technology was developed. [0003] Electrocatalytic oxidation technology degrades organic pollutants in wastewater by generating strong oxidizing active groups such as hydroxyl radicals. It has the chara...
