PURPOSE: A wastewater processing device is provided to save energy costs by evaporating wastewater with compressed heat of vapor and initial heating energy and by separating purified water from wastewater. CONSTITUTION: A wastewater processing device comprises the following steps: a wastewater supply part(1); an evaporation part(5) restoring separated and discharged vapor and waste water to a temperature-ascended state while generating vapor by heat of wastewater; a first vaporization accelerating unit(7) restoring the temperature-ascended wastewater to the evaporation part by heat-exchanging wastewater with saturated steam; a second vaporization accelerating unit(9) supplying the wastewater to the evaporation part and discharging condensed water; and a control part(11). |
