For water environmental pollution problems, sewage is one of the important pollution sources. In industrial production, it is inevitable to generate wastewater, which requires wastewater treatment equipment to perform filtration treatment to meet the discharge standards.

[0003] The existing chemical wastewater treatment methods include: physically treating wastewater by using methods such as screening filtration, sedimentation, centrifugation, adsorption, and membrane separation; using methods such as screening filtration, sedimentation, centrifugation, adsorption, and membrane separation to chemically remove heavy metal ions, organic substances, and other pollutants, and conducting system design and operation management according to specific situations to ensure that the wastewater treatment effect meets the expected discharge requirements. In a multi-stage filtration system, different mesh number filter screens can be used to intercept wastewater, but the filter screens are often blocked and need to be frequently cleaned.
