Summary:In this method for treating oil-containing drainage water, concentrated water is obtained by treating oil-containing drainage water with a reverse osmosis membrane to separate oil and salt in the oil-containing drainage water, and evaporable components in the concentrated water are evaporated to obtain a solid content. Dans ce procédé de traitement d'eau de drainage contenant de l'huile, de l'eau concentrée est obtenue par traitement d'une eau de drainage contenant de l'huile avec une membrane d'osmose inverse pour séparer l'huile et le sel dans l'eau de drainage contenant de l'huile, et des composants évaporables dans l'eau concentrée sont évaporés pour obtenir une teneur en solides. 含油排水を逆浸透膜で処理することによって前記含油排水中の油分及び塩を分離して、濃縮水を得て、前記濃縮水中の蒸発可能成分を蒸発させることによって固形分を得る、含油排水の処理方法。
