Abstract

The invention relates to a bi-directional ventilation superficial-layer static composting device and a method for composting by utilizing the same, and relates to a composting device and a method for composting by utilizing the same, aiming at solving the problems of the traditional composting technology that the land occupation area is large, the composting period is long, the odor caused by mechanical pile turning is large and the dosage of a regulation agent is large. The bi-directional ventilation superficial-layer static composting device comprises a fermentation cabin, a fermentation trough, a fermentation cabin top cover, an upper gas inlet-outlet pipe, a middle gas inlet-outlet pipe, a lower gas inlet-outlet pipe, an upper-lower ventilation fan, a middle ventilation fan, a bottom gas inlet-outlet valve, a top gas inlet-outlet valve, a middle gas inlet-outlet valve, a top exhaustion valve and a bottom exhaustion valve. The method comprises the following steps: I, mixing waste and compost to obtain a mixture I, and laying the mixture I in the fermentation trough; II, gradually fixing the fermentation trough in the fermentation cabin layer by layer, and loading the top cover on the fermentation cabin; III, changing the ventilation direction by opening and closing corresponding valves; and IV, after the fermentation, taking out the fermentation trough, mixing one part of fermented material and waste to obtain a mixture II which is used for the next composting fermentation, and taking the other part of the fermented material as a product to be sold. The bi-directional ventilation superficial-layer static composting device and the method are applied to the field of composting fermentation.

Description

technical field [0001] The invention relates to a composting device and a composting method using the device. Background technique [0002] Aerobic fermentation treatment means that solid waste and conditioner are fully mixed to form a material pile of a certain volume. Under aerobic conditions, a large number of microorganisms are used to rapidly degrade the organic matter and biological residues in the material, producing carbon dioxide and water, and releasing A large number of thermal biochemical processes. Existing composting methods mainly include strip stacking, static forced ventilation, and trough. [0003] (1) Stacking process: Generally, it is carried out in the open air. The mixed materials are piled up in long strips, and the cross-section is mostly trapezoidal or triangular. The porosity of the materials inside the stacks is maintained by regular mechanical turning and stirring, while ensuring Relatively uniform sterilization and organic matter stabilization ...
