Abstract

The invention discloses a device for harmless treatment of community household garbage and a working method thereof. The device is composed of a fermentation system fixing support, a fermentation system, an air draft system, a garbage effluent discharge pipe and a control system. Garbage needing to be fermented is placed in the device from the space above the fermentation system, then the garbage is fermented by microorganisms in the fermentation system, garbage effluent generated after fermentation is discharged from the garbage effluent discharge pipe on the side wall of the fermentation system, and when the concentration of odor in the fermentation system reaches an upper limit, the control system starts the air draft system to suck the odor in the fermentation system out and discharge the odor into a specific container. The device is novel and reasonable in structure, convenient and quick to operate, high in fermentation efficiency, and wide in application range.

Description

technical field [0001] The invention belongs to the field of garbage treatment devices, and in particular relates to a harmless treatment device for domestic garbage in a community and a working method thereof. Background technique [0002] At present, landfill and aerobic composting are the main methods of garbage fermentation in the world. Since the 1980s, with the emergence of "garbage energy science", more and more attention has been paid to the recycling of garbage resources, and the conventional anaerobic digestion technology and high-speed anaerobic composting technology of garbage have been greatly developed. [0003] To promote the harmless comprehensive treatment method of community domestic waste in my country, it is necessary to solve three key technologies in engineering technology: (1) waste crushing and sorting technology; (2) waste fermentation fertilizer technology; (3) waste incineration technology. In the initial stage of technology promotion, the technol...
