Lucid waters and lush mountains are invaluable assets，therefore, protecting the environment is another major concern for people to pursue economic development. China is a big industrial country. Wastewater treatment is the main measure to control the environment. At the same time, there are many ways to deal with it. Because the electrolytic water treatment technology will not cause secondary pollution, Known as environmentally friendly technology, or green water treatment technology, it has become more and more widely used.
The basic principle of electrolytic water treatment technology is to make direct electrochemical reaction or indirect electrochemical conversion of pollutants on the electrode, that is, direct electrolysis or indirect electrolysis.
(1) Direct electrolysis
Direct electrolysis refers to the fact that contaminants are directly oxidized or reduced on the electrode and removed from the wastewater, and can be divided into an anode process and a cathode process.
(2) Indirect electrolysis
Indirect electrolysis refers to the use of electrochemically generated redox species as reactants or catalysts to convert contaminants into less toxic substances, which are classified into reversible processes and irreversible processes.
The titanium anode for water treatment has the following characteristics:
1 will not pollute the media environment
2 can be applied under different working conditions of current density;
3 can be applied to the electrode reverse system;
4 The anode can be used repeatedly after being recoated;
5 can be used in the presence of organic compounds in the electrolyte
