Aerobic fermentation treatment system

Abstract

The invention discloses an aerobic fermentation treatment system which comprises a fermentation bin and stirring blades for stirring materials in the fermentation bin, wherein the fermentation bin is divided into at least two adjacent bin bodies, each bin body is provided with a discharging port and a feeding port, and the materials are output through the discharging port under stirring of the stirring blades. The aerobic fermentation treatment system further comprises a material conveying device, and through the material conveying device, the material at the discharge port is conveyed to a feeding port adjacent to the bin body and flows into the bin body. The fermentation bin is provided with a pipeline ventilation system which is used for supplementing oxygen and is opposite to the flow direction of materials in the bin body. According to the invention, the materials are fully and completely fermented step by step, the problems that new and old materials are mixed together and the retention time of fresh kitchen waste is short when a single-bin fermentation machine structure is adopted are completely avoided, so that each batch of materials completely meet the discharge standard requirement that the produced fertilizer is more stable due to full fermentation, the recycling of organic waste materials is really realized, peculiar smell and odor are eliminated, and environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the field of garbage collection and treatment equipment, and in particular relates to an aerobic fermentation treatment system. Background technique [0002] Existing organic waste is mainly recycled and utilized through extrusion dehydration and aerobic fermentation in the bin to produce compost fertilizer. Mixed fermentation, the fermentation temperature cannot meet the requirements, and the oxygen supply during fermentation is insufficient, resulting in unsatisfactory output results of compost fertilizer; especially in the process of processing food waste, because of its higher water content, oil and salt content and ventilation Unsmooth and other reasons, resulting in insufficient fermentation and incomplete, pungent odor still seriously pollutes the surrounding environment when the material is discharged.

Problems solved by technology

[0002] Existing organic waste is mainly recycled and utilized through extrusion dehydration and aerobic fermentation in the bin to produce compost fertilizer. Mixed fermentation, the fermentation temperature cannot meet the requirements, and the oxygen supply during fermentation is insufficient, resulting in unsatisfactory output results of compost fertilizer; especially in the process of processing food waste, because of its higher water content, oil and salt content and ventilation Unsmooth and other reasons, resulting in insufficient fermentation, pungent odor still pollutes the surrounding environment when the material is discharged, etc.

[0003] Most of the existing food waste is stirred and fermented in an inverted barrel-shaped bin. Because the feeding time is not uniform and the overall fermentation time is longer than the feeding interval, the materials in different fermentation stages are all mixed in one bin. Therefore, there are still completely unfermented materials in the discharged materials; this is also a major reason for the unsatisfactory discharge results.
