Disclosed are a method of and an apparatus for evaporating wastewater. Wastewater to be evaporated is supplied into one ends of a plurality of screws, which are disposed in parallel one after another such that pitches of rotary blades are off-set from one another. Microwave heating element containing silicon carbide is supplied through one ends of the screws to which wastewater are supplied. The screws are rotated such that the wastewater is transferred while being stirred with the microwave heating elements. Magnetrons are disposed at certain predetermined intervals along the transferring direction of the wastewater and operated such that microwave acts towards the screws. Fore infrared lamps are disposed between the magnetrons one after another and operated such that fore infrared rays act toward the screws, wherein the mixture of wastewater and microwave heating element is heated and evaporated by means of the microwave and for infrared rays while being crushed, stirred and transferred by means of the plurality of crews. The wastewater evaporation apparatus includes a frame, a chamber, a microwave heating element supplying unit, multiple crews, magnetrons and fore infrared lamps. The wastewater evaporation method and apparatus can maximize thermal efficiency to thereby effectively treat wastewater, so that the treating efficiency can be further improved and maintenance cost can be reduced. |
