NOVELTY - Biological energy source heat preservation method for fermentation of organic wastes in winter involves constructing integrated organic waste fermentation reactor; providing room for fermentation during winter, providing outer cover as heat insulating layer; adding psychrotrophic microorganism fermentation heat filler; placing organic waste to be treated in main fermentation chamber, carrying out bioenergy activation, adding psychrotrophic microorganism and culture broth and carrying out bioenergy insulation fermentation; and stabilizing temperature, and fermenting.    USE - Method for biological energy source heat preservation method for fermentation of organic wastes in winter (claimed).    DETAILED DESCRIPTION - Biological energy source heat preservation method for fermentation of organic wastes in winter comprises constructing integrated organic waste fermentation reactor by dividing container using partition material into inner chamber and outer chamber, taking main room for organic waste fermentation reaction, taking outer chamber as living room for fermentation of thermophilic microorganisms; providing room for fermentation during winter, providing outer cover as heat insulating layer and to prevent loss of bioenergy; adding filler into biological energy heat preservation room by adding psychrotrophic microorganism fermentation heat filler; placing organic waste to be treated in main fermentation chamber, carrying out bioenergy activation, adding into insulation chamber, adding psychrotrophic microorganism and culture broth and carrying out bioenergy insulation fermentation; and stabilizing temperature in bioenergy holding chamber, replacing bioenergy insulation chamber filler, carrying out filler reflux inoculation, and fermenting.
