<p>PURPOSE:To separate and recover inexpensively and efficiently a hydrophilic org. component from a hydrophilic org. component-contg. water (a gravity- separated waste water) light in the specific gravity after gravity-separating condensate in org. waste gas treating equipment. CONSTITUTION:In a distillation column 2, a heat exchange part 6 introduced with desorbed vapor and utilizing waste heat, and a temp. sensor 3 measuring temp. in the column and controlling an electric heater 5, are provided, and the gravity-separated waste water is introduced into a distillation column 2 from a separator tank 19 and the hydrophilic org. component is separated. In this way, treatment of the separated waste water becomes easy and the treatment cost is reduced.</p> |
