Abstract

The invention provides an electrode foil corrosion wastewater treatment system. The system comprises a pretreatment system, a tubular micro-filtration membrane system, a two-stage reverse osmosis system and a cleaning system, wherein the pretreatment system is used for adjusting the pH value of corrosion wastewater and decomposing pollutants in the corrosion wastewater for forming a concentrated solution; the tubular micro-filtration membrane system is used for receiving the concentrated solution conveyed from the pretreatment system and filtering suspended particles in the concentrated solution; the two-stage reverse osmosis system is connected with an output end of the tubular micro-filtration membrane system and is used for desalting a filtrate after filtration; and the cleaning systemis used for cleaning the tubular micro-filtration membrane system and the two-stage reverse osmosis system at regular time. The invention relates to an electrode foil corrosion wastewater treatment process. The process comprises the following steps: S10, adjusting the pH value of corrosion wastewater through a pretreatment system and decomposing pollutants; S20, filtering suspended particles of the concentrated solution to form a filtrate; and S30, desalting the filtrate. The electrode foil corrosion wastewater treatment system provided by the invention has the advantages of short reaction time, small occupied area and stable quality of outflow water.

Description

technical field [0001] The invention belongs to the technical field of electrode foil wastewater treatment, and more specifically relates to an electrode foil corrosion wastewater treatment system and a treatment process thereof. Background technique [0002] The electrode foil generally undergoes a corrosion process and a chemical formation process. The corrosion process uses the electronic light foil as a raw material, and the surface of the electronic light foil is etched by an electrochemical method to form holes, thereby increasing the surface area of ​​the cathode and anode light foils to increase their specific capacitance. Made into etched foil. Corrosion wastewater will be generated during the corrosion process. In the past, the treatment method for electrode foil corrosion wastewater was to discard it directly, which would greatly waste water resources. [0003] At present, some enterprises are slowly beginning to recycle electrode foil corrosion wastewater. Howev...
