Sewage electrolysis equipment

The electrolysis tank is composed of a tank body, an anode and a cathode, most of which are separated by a diaphragm from the anode chamber and the cathode chamber. According to the different electrolytes, it is divided into three types: aqueous electrolytic tank, molten salt electrolytic tank and non-aqueous electrolytic tank. When the direct current passes through the electrolytic cell, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution to prepare the desired product. Optimizing the design of the electrolytic cell structure and choosing the electrode and diaphragm materials reasonably is the key to improving current efficiency, reducing cell voltage, and saving energy consumption.


Electrolysis power

Electrolytic power sources are widely used in the metallurgical industry, such as extracting metals from ore or compounds (electrolytic metallurgy) or purifying metals (electrolytic purification), and depositing metals from solutions (electroplating). Metallic sodium and chlorine are produced by electrolysis and melting of sodium chloride; electrolysis of aqueous sodium chloride produces sodium hydroxide and chlorine. The electrolysis of water produces hydrogen and oxygen. The electrolysis of water is to decompose water into H2(g) and O2(g) under the action of an external electric field. DC power electrolysis is a very powerful means to promote redox reactions. Many difficult redox reactions can be achieved by DC power electrolysis. For example: the molten fluoride can be oxidized to elemental fluorine on the anode, and the molten lithium salt can be reduced to metallic lithium on the cathode.
