Wastewater treatment filtering plate

Abstract

The invention discloses a wastewater treatment filtering plate. The wastewater treatment filtering plate comprises a rectangular framework, wherein three filtering layers are formed inside the rectangular framework and comprise a first filtering layer, a second filtering layer and a third filtering layer; the first filtering layer is positioned at the bottom, the second filtering layer is positioned at the middle part and the third filtering layer is positioned at the top; the first filtering layer is made of porous ceramic; the second filtering layer is made of ion exchange resin, and the third filtering layer is made of activated carbon and activated carbon filter cloth. The wastewater treatment filtering plate disclosed by the invention has the advantages that partial heavy metal components in industrial wastewater can be removed and water quality of the industrial wastewater is changed while the impurities in the industrial wastewater are filtered, and the filtering treatment efficiency of the industrial wastewater is effectively improved; the wastewater treatment filtering plate has the advantages of good filtering effect and high functionality.

Description

technical field [0001] The invention relates to a waste water treatment device, in particular to a waste water treatment filter plate, which belongs to the technical field of waste water treatment. Background technique [0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants produced in the production process that are lost with water. There are many types of waste water with complex components. For example, electrolytic salt industrial waste water contains mercury, heavy metal smelting industrial waste water contains lead, cadmium and other metals, electroplating industrial waste water contains various heavy metals such as cyanide and chromium, and petroleum refining industrial waste water contains Phenol, pesticide manufacturing industrial wastew...

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants produced in the production process that are lost with water. There are many types of waste water with complex components. For example, electrolytic salt industrial waste water contains mercury, heavy metal smelting industrial waste water contains lead, cadmium and other metals, electroplating industrial waste water contains various heavy metals such as cyanide and chromium, and petroleum refining industrial waste water contains Phenol, pesticide manufacturing industrial wastewater contains various pesticides, etc. Since industrial wastewater often contains a variety of toxic substances, polluting the environment is very harmful to human health. Composition and concentration can only be discharged after taking corresponding purification measures for disposal; at present, before chemical treatment of industrial wastewater, it needs to be filtered first, but the existing filtration process is simply to filter out industrial wastewater. Impurities in wastewater, poor filtration effect, poor filtration efficiency
