The present invention relates to a food waste water and food waste treatment method. According to the present invention, food waste water resulting from food waste is directly treated by the use of a food waste byproduct, and thus energy consumption can be minimized and no secondary pollutant is generated. The food waste water treatment method according to the present invention for treating food waste water resulting from food waste includes: (a) a step of adsorbing and filtering solid matter contained in the food waste water by using, as a raw material for filtering, compost or fodder as a byproduct obtained by recycling into the compost and the fodder from food waste water-separated food waste; and (b) a step of extracting each of solid filtrate in which the raw material for filtering and the solid matter are mixed with each other through the filtering in step (a) and solid matter-removed liquid filtrate.
