Abstract: PURPOSE: Disclosed is an apparatus for treating wastewater electrochemically, in particular for treating high concentration wastewater by using electrolytic oxidation reaction adopting insoluble catalytic electrodes and a conductive floating catalyst, thereby free of additional chemicals or processes. CONSTITUTION: A reactor mainly consists of a power supplying means (1), an aerator (6), a plurality of air injection holes (10), a plurality of cathodes (4), a plurality of anodes (2). Wastewater which is stored in a storage basin (5) flows into the reactor (9) through an inlet port (8), and discharged through an outlet port (7) after contacting with anodes, cathodes, and conductive floating catalyst (3). The anode made by immobilizing Ru-Ir-Sn oxides on the surface of titanium plate decomposes organics and color-causing materials, dissolved heavy metals in wastewater are electrodeposited on the surface of cathode made of iron or nickel plate. Also, the floating titanium/iron catalyst coated with iron oxides accelerates organics decomposition through chemical reaction with hydrogen peroxide generated in the surface of anodes. In the reactor, anodes and cathodes are installed to be different height each other for maximizing contacting area between wastewater and each electrode, and aeration is accompanied to both separate bubbles generated in the each electrode and maintain wastewater flow stable.
