Problems solved by technology

The high acidity in wastewater will greatly increase the amount of alkaline substances used, resulting in high wastewater treatment costs, and the output of copper carbonate precipitates in the process of further processing can easily cause secondary pollution, which brings extreme pollution to wastewater treatment. big hidden danger
Therefore, using this method to treat high-acidity, low-concentration copper sulfate wastewater not only has high labor intensity and poor working environment, but also has high labor costs and low metal recovery rate.

Abstract

The invention relates to the field of wastewater treatment and particularly provides metallic copper, a method for treating wastewater containing copper ions and a method for electrolyzing metal ions. The method for treating the wastewater containing the copper ions comprises the following steps of 1, conducting solid-liquid separation on the wastewater containing the copper ions; and 2, introducing the wastewater which contains the copper ions and is obtained after solid-liquid separation into an electrolytic tank, and making the wastewater flow in a rotary manner in the electrolytic tank at the flow speed of 1000-15000 liter / hour, wherein the metallic copper can be gradually separated out of a cathode under the action of an electric field formed at the electric current density of 50-1200 A / m<2>. The method has the beneficial effects of being simple in technology, short in technological process, low in cost, high in treatment efficiency and wide in treatment concentration range.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to metal copper, a method for treating wastewater containing copper ions and a method for electrolyzing metal ions. Background technique [0002] Electrolysis is a process in which an electric current passes through a substance to cause a chemical change, and a chemical change is a process in which a substance loses or gains electrons (oxidation or reduction). The electrolysis process is carried out in an electrolytic cell. The electrolytic cell is composed of two electrodes, an anode and an anode, respectively immersed in a solution containing positive and negative ions. The current flows into the negative electrode (cathode), and the positively charged positive ions in the solution Migrate to the cathode and combine with electrons to become neutral elements or molecules; negatively charged negative ions migrate to the other electrode (anode), donate electrons, and become neutral el...
