Abstract

The invention discloses a device for comprehensively recovering copper and silver from waste water and a using method thereof, and particularly relates to the technical field of waste water treatment. The device comprises a device body, wherein a wastewater treatment cavity is formed in the device body, a heating assembly is arranged on the outer side of the wastewater treatment cavity, an impact mechanism is arranged at the top of the wastewater treatment cavity, the heating assembly comprises an annular heat transfer plate, an annular sealing cover is welded to the outer side of the annular heat transfer plate, a liquid heat transfer medium layer is arranged in the annular sealing cover, and a plurality of electric heating rods are fixedly installed in the annular sealing cover. According to the invention, through the arrangement of the heating assembly and the impact mechanism, when wastewater is electrolyzed, the wastewater can be kept at a relatively high temperature, the resistance of the wastewater is reduced, and electrolysis treatment is facilitated, so that the electrolysis efficiency is improved so as to improve the recovery efficiency of silver and copper in the wastewater, and the actual use effect of the device is relatively good.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, more specifically, the invention relates to a device for comprehensively recovering copper and silver in waste water and a method for using the same. Background technique [0002] Wastewater refers to the water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other useless water such as primary rainwater flowing into drainage pipes and canals. Wastewater is recognized as one of the three major public hazards in nature. To treat wastewater, At present, there is a comprehensive recovery device for silver and copper in wastewater to recover silver and copper in wastewater, so as to avoid pollution of the natural environment by silver and copper heavy metal ions in wastewater. [0003] Although the silver-copper comprehensive recovery device in the wastewater in the prior art can be used normally, there are still many ...
