Abstract

The invention provides a device for treating wastewater generated by foil corrosion. The device comprises a main tank body, wherein a solid-liquid separation chamber, a sedimentation chamber, an adsorption chamber and a discharge chamber are formed in the main tank body from top to bottom in sequence, the upper end of the solid-liquid separation chamber is provided with a water inlet pipe, the side face of the solid-liquid separation chamber is provided with an electric telescopic column, the telescopic end of the electric telescopic column is fixedly connected with a scraper, the side, away from the electric telescopic column, of the solid-liquid separation chamber is provided with a solid waste collection port, the solid waste collection port is provided with a movable baffle plate, a plate grid structure is formed between the solid-liquid separation chamber and the sedimentation chamber, the sedimentation chamber is communicated with the upper middle of the side face of the adsorption chamber through a U-shaped tube, the lower surface of the adsorption chamber is provided with an adsorption plate and filled with adsorbed substances, the lower portion of the discharge chamber isprovided with a water outlet pipe, and a solid waste collection tank is placed at the solid waste collection port. The device for treating the wastewater generated by the foil corrosion improves the utilization rate of the wastewater, and is simple in structure and convenient to operate.

Description

technical field [0001] The invention belongs to the field of environmental protection wastewater treatment, in particular to a wastewater treatment device for corroded foil production. Background technique [0002] Corrosion foil is the key raw material for the production of electronic capacitors. Hydrochloric acid bath, hydrochloric acid + sulfuric acid mixed acid bath or nitric acid bath is used to electrolytically corrode aluminum light foil to improve the specific capacity of aluminum foil. Electronic corrosion foil is used in the production process of aluminum electrolytic etching. Using a hydrochloric acid bath, a hydrochloric acid-sulfuric acid mixed acid bath or a mixed acid bath such as nitric acid will produce some waste acid. After the aluminum foil electrolysis is etched and washed with a large amount of ultrapure water, waste water will be generated. The total waste acid and waste water will be discharged annually. These wastewaters are directly discharged witho...
