Application of electrocatalytic titanium oxide electrode technology in wastewater treatment

With the development of environmental science and technology, more efficient, economic pollutant treatment technology gradually valued and utilization, electrochemical technology for environmental pollutants is one of the newly developed environmental pollution control technology, electrochemical technology has low operating cost, high efficiency, does not produce two pollution, simple equipment, both air float, flocculation, sterilization, especially for biodegradable removal of toxic pollutants is very effective, is more active research at home and abroad. 

Electrocatalytic oxidation wastewater treatment has redox, condensation, air float, emulsion, milk breaking, salt analysis, sterilization and adsorption and other functions, and has the advantages of small equipment volume, small area, simple and flexible operation, can remove a variety of pollutants, but also can recover the precious metals in the wastewater. In recent years, it has been widely used in the treatment of electroplating wastewater, chemical wastewater, printing and dyeing wastewater, pharmaceutical wastewater, leather wastewater, paper black liquid and other occasions.

Electrochemical treatment method of pollutants: The application of electrochemical method in the treatment of sewage, waste gas and heavy metal ions can be divided into direct oxidation, indirect oxidation, photoelectric chemical oxidation, electroreduction, and electroflotation / electroflocculation.
