A pre-treatment equipment for wastewater treatment is provided to remove a portion of water contained in the wastewater before changing a water contaminant(wastewater) generated in the food waste treating process into an oil material and before recycling a water contaminant(wastewater) generated in ordinary sorting, crushing, feedstuff-preparation, composting processes into resources, and easily disassemble and repair the equipment during breakdown of the equipment. In an equipment for pre-treatment performed before treating wastewater generated in ordinary treatment processes including feedstuff-preparation, composting and the like of food waste, the pre-treatment equipment for wastewater treatment comprises: a container(100) for containing the wastewater; an injection pipe(2) for injecting wastewater into the container; an agitator(5) for agitating the wastewater injected by the injection pipe; a rotary shaft(3) for providing the agitator with rotary power; a motor for providing the rotary shaft with power; removable heating plates(7) for supplying heat to the wastewater; receiving members(6) for receiving the heating plates; a heating plate(7) formed on the entire face of a bottom part of the container; an exhaust pipe(10) for exhausting water vapor evaporated by the heating plates; a cooler for cooling the water vapor exhausted by the exhaust pipe; a water tank for containing water converted from the water vapor by the cooler; a suction pipe(13) for injecting water vapor that has not been cooled by the cooler into the container again; a connector(21) for providing a wastewater treatment apparatus with water-reduced wastewater; and a water lifting machine for supplying the wastewater from the connector to the wastewater treatment apparatus.
