20090127194	ELECTRODIALYSIS REVERSAL AND ELECTROCHEMICAL WASTEWATER TREATMENT METHOD OF COMPOUND CONTAINING NITROGEN - Provided is a wastewater treatment method using an electrodialysis reversal (EDR)-electrochemical wastewater treatment (EWT) combined process, the method including: separating inflow wastewater which contains nitrogen compounds into product water and concentrated water using an EDR facility; and decomposing the concentrated water into target materials to be eliminated from the wastewater in an EWT facility. Provided is a wastewater treatment method for decomposing inflow water containing a nitrogen-containing compound into target materials to be eliminated using an EWT facility alone. According to the wastewater treatment method, product water which is flowed out from an EDR facility can be reused as raw water, and the method guarantees reliability and stability by simultaneously processing recalcitrant COD and T-N in the concentrated water. The wastewater treatment method efficiently removes recalcitrant COD and T-N, which are derived from ethanolamine (ETA), in wastewater produced in a power plant and an industrial facility using ETA as a pH-adjusting agent. EDR-EWT process can be easily combined with a common wastewater treatment and can efficiently and stably treat wastewater containing recalcitrant COD and T-N. Therefore, the method can actively satisfy the strengthening environmental regulation criteria.	05-21-2009
