The basic principle of electrochemical water treatment titanium anode technology is to make the pollutants undergo direct electrochemical reaction or indirect electrochemical transformation on the electrode, i.e. direct electrolysis and electrolysis. Indirect.

Direct electrolysis refers to the removal of pollutants from wastewater by oxidation or reduction directly on electrodes. Direct electrolysis can be divided into anodic process and cathode process; Indirect electrolysis refers to the use of electrochemically generated redox agents as reactants or catalysts to convert pollutants into less toxic substances. Indirect electrolysis is divided into reversible and irreversible processes.    1. Phân loại Công nghệ xử lý nước điện hóa

    1. Electrocoagulation float method: Under the effect of external voltage, the anode is oxidized, producing a large number of cations, then forming a colloid to condense impurities in the wastewater, this method called floating capacitor electrocoagulation.

    2. Electrodeposition method: Using the potential difference of different metal components in the electrolyte to precipitate dissolved metals in the free or bound state at the cathode.

    3. Electrochemical oxidation method: The electrochemical oxidation process is divided into direct oxidation and indirect oxidation, belonging to the reaction process at the anode. Direct oxidation is the direct conversion of a pollutant to a harmless substance through anodic oxidation; indirect oxidation is to produce intermediates with strong oxidizing effect through anodic reaction or other intermediate reactions with anodic reaction, so that the treated pollutants are oxidized and finally converted into harmless substances.

   4. Electrofiltration: Based on the unique function of selectively permeating the membrane under the action of an electric field, ions can enter from one solution into another to achieve separation and concentration of ionized pollutants. When using dialysis water for titanium anode treatment to treat metal ions, the solid metal cannot be recovered directly, but a concentrated salt solution can be obtained, and the quality of the output wastewater can be improved. significantly.

   5. Electrochemical membrane separation method: The separation process using potential difference on both sides of the membrane is commonly used to separate gaseous pollutants.

Advantages of electrochemical water treatment technology

   1. The oh radicals generated during electrolysis titanium electrode can directly react with organic pollutants in wastewater and decompose them into carbon dioxide, water and simple organic substances, without or rarely produce secondary pollution, this is a high environmental technology.

   2. DSA shows energy savings (>23%) in the chlor-alkali industry, high energy efficiency and general electrochemical processes can be performed at normal temperature and pressure.

   3. Electrochemical methods can be used alone or in combination with other treatment methods, for example pretreatment, the biodegradability of wastewater can be improved.

   4. The electrolytic device and its operation are generally relatively simple and cost-effective.
