Electrocatalytic oxidation of wastewater treatment equipment

Abstract

This utility model discloses an electrocatalytic oxidation wastewater treatment device, relating to the field of wastewater treatment technology. An observation window is located in the center of the front face of the main body of the device, and a filter box is located at the center of the top right side of the main body. An inlet is located at the center of the top of the filter box, and an outlet pipe is located at the center of the bottom left side of the filter box. A through hole matching the outlet pipe is located at the center of the top of the filter box, and the left side of the outlet pipe extends through the through hole to the right side of the inner cavity of the filter box. During the wastewater treatment process, before the wastewater officially enters the main body of the device, it first undergoes pretreatment through a dedicated filter box. The main function of this filter box is to effectively filter and intercept lumpy and other larger particulate impurities in the wastewater. This step significantly reduces the amount of these impurities entering the main body of the device, thereby preventing a large accumulation of impurities within the device and thus avoiding impacting the overall wastewater treatment effect.

Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an electrocatalytic oxidation wastewater treatment device. Background Technology

[0002] Electrocatalytic oxidation wastewater treatment equipment is an environmentally friendly device that utilizes electrochemical principles to generate strong oxidizing substances through electrode reactions, thereby efficiently degrading organic pollutants in wastewater. By applying an external voltage, the equipment induces a redox reaction on the electrode surface, generating highly oxidizing active substances such as hydroxyl radicals. These active substances rapidly decompose organic pollutants in wastewater, converting them into harmless substances such as water and carbon dioxide, thus purifying the water. Electrocatalytic oxidation wastewater treatment equipment boasts advantages such as high treatment efficiency, simple operation, and no secondary pollution, and is widely used in the treatment of industrial wastewater and domestic sewage, providing strong support for the sustainable use of water resources. However, existing electrocatalytic oxidation wastewater treatment equipment still has some drawbacks. For example, the wastewater cannot be agitated before entering the equipment, resulting in poor treatment efficiency and slow wastewater treatment. Furthermore, the wastewater cannot be filtered before entering the equipment, affecting the treatment effect. Therefore, we propose an electrocatalytic oxidation wastewater treatment device. Utility Model Content

[0003] The purpose of this invention is to provide an electrocatalytic oxidation wastewater treatment device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An electrocatalytic oxidation wastewater treatment device includes a main body and a filter box;

[0006] Support legs are provided around the bottom of the main body of the equipment. An observation window is provided in the middle of the front face of the main body of the equipment. A filter box is provided in the center of the top right side of the main body of the equipment.

[0007] The filter box has an inlet at the top center and an outlet pipe at the bottom center on the left side. The filter box also has a through hole at the top center that matches the outlet pipe, and the outlet pipe extends through the through hole to the right side of the filter box's inner cavity.

[0008] A low-speed motor is located at the top center of the main body of the equipment. A motor shaft is located at the bottom of the low-speed motor, and the bottom of the motor shaft extends through the top of the inner cavity of the main body of the equipment. A connecting block is located at the bottom of the motor shaft. A crossbar is located on both the left and right sides of the connecting block. A stirring blade is located at the end of the crossbar away from the connecting block. Multiple sets of anode plates are located at the bottom left side of the inner cavity of the main body of the equipment, and each anode plate has a mounting base one at its bottom. Multiple sets of cathode plates are located at the bottom right side of the inner cavity of the main body of the equipment, and each cathode plate has a mounting base two at its bottom. A drain pipe is located at the center left side of the main body of the equipment.

[0009] Furthermore: Fixing blocks are installed on the top left side of both the front and rear ends of the filter box, and bolts are installed between the right side of the fixing blocks and the right side of the main body of the equipment.

[0010] Furthermore, the inner cavity of the filter box is equipped with a primary filter and a secondary filter from top to bottom, with the pore diameter of the primary filter being larger than that of the secondary filter.

[0011] Furthermore, a maintenance cover is provided on the rear end face of the filter box, and fixing bolts are provided around the rear end face of the maintenance cover and around the rear end face of the filter box.

[0012] Furthermore, a rubber sealing ring is installed between the inner wall of the through hole and the water outlet pipe, and a sloping water outlet is provided on the left side of the water outlet pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this electrocatalytic oxidation wastewater treatment equipment, before the wastewater officially enters the main body of the equipment, it undergoes pretreatment through a dedicated filter box. The main function of this filter box is to effectively filter and intercept lumpy and other larger particulate impurities in the wastewater. This step significantly reduces the amount of these impurities entering the main body of the equipment, thus preventing a large accumulation of impurities that could affect the overall wastewater treatment effect. When the pre-filtered wastewater smoothly enters the main body of the equipment, the low-speed motor installed inside the equipment starts working. The motor shaft of the low-speed motor drives the connecting block to rotate smoothly. During the rotation of the connecting block, it further drives the stirring blades to rotate through the crossbar connected to it. The stirring blades rotate continuously inside the main body of the equipment, thereby agitating the wastewater. This agitation not only promotes the uniform distribution of suspended solids and dissolved oxygen in the wastewater, but also effectively prevents the wastewater from remaining stagnant inside the equipment for a long time. If the wastewater remains stagnant for a long time, it will not only affect the wastewater treatment effect, but may also lead to a decrease in treatment efficiency. Attached Figure Description
