PURPOSE: To raise the efficiency of waste water treating operation, by injecting evaporated mist formed in an evaporator from a nozzle into an incinerating means together with fuel oil in an apparatus in which organic waste water is introduced into a distiller for condensation therein and the condensated mother liquid thus obtained is burned in an incinerating means.
CONSTITUTION: Organic waste water is introduced into a distiller 2 from a direction A, in which it is heated by a proper heat source. Condensate in the distiller 2 is extracted as shown by an arrow B and injected from nozzles 4 into a single fuel combustion means 1 for combustion therein. The single fuel combustion means 1 is formed with a flame hole 7 into which flame is blown from a secondary burner, and the exhaust gas is discharged to the outside from an outlet port 6 in the direction shown by an arrow H. Here, evaporated mist extracted from the distiller 2 in the direction shown by an arrow C is carried into a thermocompressor 3 and then into a nozzle body 9, in which it is mixed with steam supplied from a direction D and fuel oil supplied from a direction E. Further, it is mixed wigh high-temperature combustion air supplied from the direction shown by an arrow F and then injected into the combustion means 1 for burning the condensate supplied from the distiller 2.
