Titanium Anode for Sewage Treatment

Titanium anode for sewage treatment

With the rapid development of industry and agriculture and population growth, the sewage discharged by human beings has increased dramatically, resulting in many water areas being polluted to varying degrees. Electrochemical treatment of sewage can be divided into direct electrolysis and indirect electrolysis.

1.Direct electrolysis means that pollutants are directly oxidized or reduced on clicks and removed from wastewater. Direct electrolysis can be divided into cathode process and anode process

2.Indirect electrolysis refers to the use of redox substances generated by electrochemistry as a reflection agent or catalyst to convert pollutants into less toxic substances. Indirect electrolysis can be divided into reversible process and irreversible process

Titanium anode for sewage treatment application:

Applied to printing wastewater treatment, landfill leachate treatment, feces wastewater treatment, cyanide-containing wastewater treatment, pharmaceutical wastewater treatment, hospital wastewater treatment, organic wastewater treatment

In order to effectively remove COD,BOD and ensure a large electrolytic area, sewage treatment requires assembled anode and parallel electrolysis, with mesh structure being the majority.

Titanium anode for ammonia nitrogen wastewater treatment

The experimental results show that the best current density of electrolysis to remove ammonia nitrogen and total nitrogen is 80mA/cm2, the distance between the plates is 30mm, the mass concentration of chloride ions is 7000mg/L, and the pH is 9-11. Under the above conditions, the reaction is 7h , The mass concentration of total nitrogen dropped from 3000mg/L to 379.4mg/L, and the removal rate reached 87.35%. The removal of total nitrogen by electrolytic oxidation basically conforms to the law of first-order reaction kinetics.
