Embodiment 1

[0023] Such as figure 1 As shown, a multi-stage fermentation system includes a rack body 1, and the rack body 1 includes a top wall 2 and two side walls 3 connected to the top wall 2, and a plurality of sets of The supporting strips 4 are provided with ventilation pipes 5 on the top wall 2; the multi-stage fermentation system also includes a plurality of drawer-type boxes, and the plurality of drawer-type boxes are respectively arranged on the plurality of sets of supports in a slidable manner. on the slat 4, so that the fermentation chamber is formed in the drawer-type box, and the bottom of the drawer-type box is as figure 2 A plurality of ventilation holes are provided, and the bottom of the drawer-type box body is provided with 10 in a manner that can be opened or closed.

[0024] Put the organic solid waste: poultry manure into the first drawer box 6 to ferment for 7 days, then fill the second drawer box 7 with organic solid waste, and wait in the second drawer box 7 W...

Embodiment 2

[0027] In this embodiment, the organic solid waste poultry manure is replaced with sugar factory filter mud, and it is fermented for 11 days. Four drawer-type boxes are installed in total: the first drawer-type box, the second drawer-type box, and the third drawer-type box. For the drawer-type cabinet and the fourth drawer-type cabinet, the air enters from the bottom of the opening of the fourth drawer-type cabinet, and then flows out through the ventilation pipe on the top wall of the frame body to form a passage airflow. Others are no different from Example 1.

Embodiment 3

[0029] In this embodiment, the organic solid waste poultry manure is replaced by agricultural straw waste, and 5 drawer-type boxes are installed in total: the first drawer-type box, the second drawer-type box, and the third drawer-type box. , the fourth drawer box, the fifth drawer box, the air enters from the bottom of the opening of the fifth drawer box, and then flows out from the air pipe on the top wall of the frame to form a passage air flow. Fermentation 14 days, other are no different from embodiment 1.

[0030] In the above-mentioned embodiments, the number of drawer-type cabinets can be increased or decreased at will according to the needs of on-site fermentation, but no matter how the number of drawer-type cabinets is increased or decreased, the number of drawer-type cabinets in the entire fermentation system must be at least three or more.

[0031] Using the multi-stage fermentation system of the present invention to process organic solid waste can effectively solv...

Abstract

The invention discloses a multi-section fermentation system. The multi-section fermentation system contains a frame body, and drawer-type box bodies, wherein the plurality of drawer-type box bodies are arranged on a plurality of groups of support battens in a slidable manner respectively, a plurality of air vents are formed in the bottom of each drawer-type box body, and the bottom of each drawer-type box body is arranged in an openable or closable manner. A method for using the system for treating organic solid wastes comprises the following steps: placing the organic solid wastes in the drawer-type box bodies and fermenting for 7-15 days, then filling the organic solid wastes in the next layer of drawer-type box bodies and fermenting for 7-15 days, and then filling the organic solid wastes in the next layer of drawer-type box bodies and fermenting. By using the multi-section fermentation system disclosed by the invention for treating the organic solid wastes, the problem that lots of ammonia gas generated during a treatment process for the organic solid wastes is discharged to air can be effectively solved, and the nitrogen content and the fertilizer efficiency of an organic fertilizer are increased; by using the fermentation system disclosed by the invention for fermentation, the nitrogen content in the obtained organic fertilizer is increased by more than twice.

Description

technical field [0001] The invention relates to the field of organic solid waste treatment, in particular to a multi-stage fermentation system and its application in organic solid waste treatment. Background technique [0002] Recycling of organic solid waste to produce organic fertilizers has important environmental protection and social and economic benefits. During the fermentation process, a large amount of heat and ammonia will be generated, causing ammonia to volatilize, resulting in serious nitrogen loss in organic fertilizers and poor fertilizer efficiency. , low quality, and pollute the environment. Therefore, how to reduce ammonia emissions and increase the nitrogen content of organic fertilizers has become a key technical issue in the production of organic fertilizers by fermenting organic solid waste. [0003] At present, there are mainly three kinds of system equipment or operation methods for the fermentation of organic solid wastes to produce organic fertiliz...
