Description

Technical Field

[0001] The utility model relates to the technical field of domestic garbage treatment, in particular to a turnover type domestic garbage aerobic bioreactor. Background Art

[0002] Aerobic composting technology is to allow aerobic bacteria to decompose organic matter in garbage under the condition of sufficient oxygen supply, otherwise anaerobic reactions will occur and produce odor.

[0003] In order to make the materials fully contact with air (oxygen), the common methods are: open fermentation, generally 4-5 times of turning the pile to fully decompose the garbage. In order to facilitate turning the pile, the pile height is limited to within 1.5 meters. Each turning of the pile will cost a lot of manpower and material resources, and a large amount of odor will be generated during turning the pile, which is difficult to control and affects the environment. There will also be dead corners in the turning process. This part of the garbage is not fully decomposed due to lack of contact with the air, affecting the quality; closed cabin container fermentation, air is generally forced into the closed container, and the air can be blown in (positive pressure) or sucked in (negative pressure). This method generally introduces air from the bottom to ensure the oxygen demand of the garbage at the bottom. However, forced air consumption is large.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
