An apparatus is provided to recycle wastewater generated in the food waste treatment process into resources such as livestock feeds by removing a portion of water contained in the wastewater, and to recycle wastewater generated through ordinary sorting, crushing, feed-forming and composting processes into resources by effectively removing a portion of water contained in the wastewater without a separate treatment apparatus. A wastewater treatment apparatus comprises: a first housing body(10) including a housing vessel(155) containing wastewater; a wastewater inflow part(110) into which the wastewater flows; an agitator(120) for mixing the wastewater; an oil pipe(125) spirally formed in contact with an inner part of the housing vessel to pass oil with a high temperature and supply heat to the wastewater; an oil heater(130) for heating oil that supplies heat to the wastewater through the oil pipe; a steam discharge pipe(140) for discharging steam evaporated from the wastewater by heat supplied from the oil pipe; and a wastewater discharge part(115) for discharging wastewater with a reduced water content. The wastewater treatment apparatus further comprises a second housing body(20) including a housing vessel(250), a wastewater inflow part(210), a wastewater transfer pump(220), an agitator, a wastewater discharge part(215), a steam inflow part, a steam moving pipe, a steam discharge pipe(245), and a steam discharge part(235). The wastewater treatment apparatus further comprises a third housing body(30) including a housing vessel(345), a wastewater inflow part(310), an agitator(340), a wastewater discharge part(315), a wastewater transfer pump(320), a steam inflow part, a steam moving pipe, and a water discharge part(335). Further, the wastewater treatment apparatus additionally comprises a compression valve for discharging a high temperature and high pressure of vapor and an oil pump for transferring rapidly a high temperature of oil to the oil pipe. |
