Zusammenfassung:	Provided is a method for purifying of waste water including: supplying a mixed stream in which wastewater including water, a nitrile-based monomer, and ammonia and an acid component are mixed to a first column; condensing an upper discharge stream of the first column, supplying the condensed stream to a decanter to separate into a water layer and an organic layer, and supplying components of the organic layer to a second column; and separating a by-product from a lower discharge stream of the second column, and recovering the nitrile-based monomer from an upper discharge stream of the second column.
