[0002] Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to the wastewater and waste liquid generated during industrial production. It contains industrial production materials, intermediate products, by-products and pollutants generated during the production process that are lost with water. There are many types of industrial wastewater with complex components. For example, electrolytic salt industrial wastewater contains mercury, heavy metal smelting industrial wastewater contains various metals such as lead and cadmium, electroplating industrial wastewater contains cyanide and various heavy metals such as chromium, petroleum refining industrial wastewater contains phenol, and pesticide manufacturing industrial wastewater contains various pesticides, etc. Since industrial wastewater often contains various toxic substances, it pollutes the environment and poses a great harm to human health. Therefore, comprehensive utilization should be developed to turn harm into benefit. After taking corresponding purification measures according to the components and concentrations of pollutants in the wastewater, it can be discharged. Currently, most of the treatment of environmentally friendly industrial wastewater is to transport the industrial wastewater to a filtration device for treatment. Since industrial wastewater contains various impurities, the impurities in the wastewater are likely to remain in the filtration device during filtration. Especially when the filter plates in the device are used for a long time, more and more impurities accumulate on the filter plates. And the filter plates are installed in the box and are not convenient to disassemble and clean, which will affect the filtration effect of the filtration device after long-term use.
