PURPOSE: Provided is a wastewater treatment system using advanced electric oxidation process. In detail, the system can treat non-degradable components and toxic materials in wastewater by adding hydrogen peroxide and ferrous chloride and applying a weak electric current at the same time. CONSTITUTION: The wastewater treatment system consists of the following parts: a reservoir (1); a chemicals tank (8) containing sulfuric acid, hydrogen peroxide, ferrous chloride, sodium hydroxide and coagulants; a first pH adjusting tank (2) equipped with stirrers (10); a reaction tank (3) to treat wastewater through advanced oxidation using Fenton; a second pH adjusting tank (4) to neutralize secondly wastewater by sodium hydroxide; a flocculation tank (5) adding polymer and connected from valves (6a,6b,6c,6d,6e); and an electric current supplier (7).
