[0002] Industrial wastewater refers to wastewater and waste liquid discharged during the production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with the water. It is an important cause of environmental pollution, especially water pollution. In order to avoid environmental pollution and waste of water resources, industrial wastewater is usually treated by purification, which requires the use of wastewater purification equipment.

[0003] However, there are still some problems when using the existing green and low-carbon industrial wastewater treatment and purification devices: There is an acidic industrial wastewater purification treatment device with Chinese patent application number CN202010692470.4, which includes a base, a servo motor is installed on the top of the mounting frame, a rotating rod is installed on the power end of the bottom of the servo motor, and a material spreading assembly and blades are arranged on the outer wall of the rotating rod from top to bottom, and a discharge channel is arranged at the bottom of the reactor; The wastewater purification process is not convenient for pre-filtering impurities such as sludge in the wastewater, and directly mixes with the reagents, which has low efficiency for subsequent treatment. At the same time, because the existing equipment can only provide unidirectional stirring, the mixing efficiency and dissolution efficiency of the reagents are low, which affects the purification efficiency of the wastewater; The existing mixing of wastewater and chemicals is done simply by stirring, which has low mixing efficiency and requires long-term stirring to ensure uniform mixing. In addition, since wastewater may generate waste gas during the treatment process, existing equipment cannot treat waste gas and carbon dioxide, which can easily cause environmental pollution.

[0004] In response to the above problems, an innovative design was carried out based on the original green and low-carbon industrial wastewater treatment and purification device. Summary of the invention

[0005] The purpose of the present invention is to provide a green and low-carbon industrial wastewater treatment and purification device to solve the problems of low mixing efficiency of chemicals and wastewater in existing wastewater treatment and purification devices mentioned in the above background technology, such as the difficulty of dissolving chemicals and uneven mixing, and low purification efficiency of wastewater due to the need for long-term stirring.

An activated carbon adsorption plate is arranged at the lower end of the filter plate, and the activated carbon adsorption plate is snap-connected to the inner wall of the exhaust pipe.

[0008] By adopting the above technical scheme, through the cooperation of the filter plate and the activated carbon adsorption plate, the waste gas generated in the process of industrial wastewater treatment can be further filtered and treated to avoid direct discharge of polluted air. The activated carbon adsorption plate can adsorb carbon dioxide to a certain extent, reduce carbon emissions, and be more environmentally friendly.

To avoid blockage, when the second transmission plate drives the scraper plate to rotate, the scraper plate can be used to clean the sludge and other materials attached to the inner wall of the pre-filter barrel and drop them to the bottom of the pre-filter barrel for easy collection and treatment.

[0011] Preferably, the bottom end of the pre-filter barrel is designed with a conical structure, the bottom end of the scraper plate is connected to a guide plate, and the lower end of the guide plate is adapted to the shape of the inner wall of the lower end of the pre-filter barrel, and the lower end of the guide plate contacts the inner wall of the pre-filter barrel.

[0024] 1. By setting up the impeller structure, the first impeller can be driven to rotate by the water flow while the stirring structure rotates around the second rotating shaft, thereby providing vertical rotation power for the second stirring shaft. The second stirring shaft and the stirring blades revolve and rotate at the same time, providing multi-directional stirring, improving the dissolution rate and dissolution uniformity of the agent, and improving the treatment efficiency of industrial wastewater; 2. By setting up an air supply structure, air is injected into the main body of the device to generate bubbles during stirring, and the rotating guide blades cut the bubbles to form more small bubbles. The mixing of bubbles and wastewater can further improve the dissolution efficiency of the agent, and the waste gas generated during wastewater treatment can be filtered and treated to avoid environmental pollution. The activated carbon adsorption plate is used to adsorb carbon dioxide and reduce carbon emissions. BRIEF DESCRIPTION OF THE DRAWINGS
