Technical Field

[0001] The utility model relates to the technical field of industrial sewage treatment, in particular to a purification device for industrial sewage. Background Art

[0002] Industrial wastewater refers to wastewater generated in the process of industrial production. This wastewater usually contains various organic matter, inorganic salts, heavy metal ions, oils, suspended matter, bacteria and microorganisms. The composition and properties of industrial wastewater depend on the specific process of industrial production and the raw materials involved. Industrial wastewater needs to undergo a specific treatment process to meet the discharge standards or reuse requirements. When treating wastewater, an industrial wastewater purification device is needed to remove pollutants from the industrial wastewater to meet the discharge requirements. In the existing purification devices, grids and screens are usually used to precipitate impurities and suspended matter in the sewage during the purification process. Due to the presence of micro-particles and heavy metal ions in industrial wastewater, such impurities are difficult to be captured through the pores of the grid, resulting in substandard water quality after sewage treatment and failure to meet discharge standards or reuse requirements. Therefore, we propose an industrial wastewater purification device to solve the above-mentioned problems. Utility Model Content
