Kitchen waste leachate treatment and utilization device

The invention discloses a kitchen waste leachate treatment and utilization device which comprises a high-temperature anaerobic digestion bin, an anoxic reaction bin and a membrane separation bin; a first stirring device and a folded plate are arranged in the high-temperature anaerobic digestion bin, and an isolation bin in which microbe balls for fixing anaerobic bacteria are placed is arranged at the lower part of the high-temperature anaerobic digestion bin; the high-temperature anaerobic digestion bin is communicated with the anoxic reaction bin, a hollow second stirring device is arranged in the anoxic reaction bin, and aeration holes are formed in stirring blades; through aeration holes, dissolved oxygen with a certain concentration is introduced into the anoxic reaction bin as required; an outlet of the anoxic reaction bin is communicated with a pressure pump; an outlet of the pressure pump is communicated with a nanofiltration membrane water outlet pipe which is positioned in the membrane separation bin and is made of a nanofiltration membrane; micromolecular organic substances in the wastewater are further concentrated in a nanofiltration membrane water outlet pipe, and clear water passes through the nanofiltration membrane to be gathered in the membrane separation bin and then is connected into the water inlet of the high-temperature anaerobic digestion bin through a clear water return pipe. The device is high in resource utilization rate, high in degradation efficiency and low in clean sludge output.
