[0002] Industrial wastewater includes production wastewater, production wastewater and cooling water, which refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. Industrial wastewater is of various types and complex in composition. For example, electrolytic salt industrial wastewater contains mercury, and heavy metal smelting industrial wastewater contains various heavy metal toxic substances such as lead and cadmium. Direct discharge not only pollutes the environment but also has great harm to human health. Therefore, industrial wastewater needs to be treated and industrial wastewater treatment equipment is needed.

[0003] During the sewage treatment process, some chemicals are usually added to help remove pollutants, improve treatment efficiency, and ensure that the final water quality meets the standards. After adding chemicals to treat the sewage, a filtration step is usually performed to remove suspended matter, flocculated clumps, chemical precipitates, etc. The main purpose is to further improve the water quality, make the water clearer, reduce the content of suspended matter, and remove residual chemicals.

[0004] However, after adding chemical substances, only a single stirring column is used for stirring and mixing, which will result in low mixing efficiency and is not conducive to the rapid and effective treatment of sewage. At the same time, if the chemical substances and sewage are not mixed evenly, pollutants in some areas cannot be fully treated, reducing the treatment effect and even affecting the subsequent water quality requirements. Therefore, industrial wastewater recovery and purification equipment is proposed to solve the above problems. Utility Model Content

[0034] Specifically, in the process of stirring the sewage and chemicals, the motor 9 will drive the stirring rod 13 to rotate and stir continuously, and the rotating disk 10 on one side of the outer wall of the stirring rod 13 will also rotate synchronously, and the rack 11 on the outer wall of the rotating disk 10 will drive the gear 12 to start rotating.
