The invention relates to recycling of kitchen waste water, in particular to a method for preparing animal drinking water or feed mixing water from kitchen waste water. The method comprises the following steps: preparing a biological flocculent in which yeast group series are taken as main components; storing the kitchen waste water in a heating storage tank, and heating at a temperature over 60 DEG C for over 15 minutes to effectively kill pathogenic bacteria; realizing solid-oil-water separation on the heated and sterilized kitchen waste water through a three-phase centrifugal machine, wherein separated water is emulsible liquid containing suspended solids; adding a biological flocculent into the separated water for stirring, storing the mixture in a flocculent precipitating tank for flocculation and precipitation for over 24 hours; adding activated EMs (Effective Microorganisms) into flocculation and precipitation liquid, and filling after stirring to obtain the animal drinking water or feed mixing water. A feasible method is provided for the preparation of feed raw materials by recycling of the kitchen waste water.
