Problems solved by technology

The fermentation conditions of this fermentation method are not easy to master, and the odor during the fermentation process will affect the surrounding environment
In addition, because the fermentation of chicken manure is aerobic fermentation, it needs to be continuously turned over during the actual fermentation process to ensure its oxygen delivery. However, this method not only increases the labor intensity of workers, but also tends to cause insufficient oxygen supply locally Incomplete fermentation will affect the fertilizer efficiency and application effect of chicken manure organic fertilizer

Embodiment 1

[0017] The closed solid-state continuous chicken manure organic fertilizer fermentation method of the present embodiment is realized through the following steps:

[0018] (1) Moisture control: collect the wet chicken manure and dry it to a moisture content of 60%;

[0019] (2) Preparation of fermentation equipment: establish a closed fermentation room, and ensure that the roof of the fermentation room is transparent. Set up multiple side-by-side primary fermentation tanks and multiple side-by-side secondary fermentation tanks in the closed fermentation room. The bottom position is buried with several oxygenation pipes, and the top of the oxygenation pipes has a number of pores, which are exposed in the cavity of the fermentation tank, and the oxygenation pump is used to transport air or oxygen to the oxygenation pipes The top of the sealed fermentation chamber is connected with a negative pressure exhaust pipe, the other end of the negative pressure exhaust pipe is connected w...

Embodiment 2

[0024] The closed solid-state continuous chicken manure organic fertilizer fermentation method of the present embodiment is realized through the following steps:

[0025] (1) Moisture control: collect wet chicken manure and dry it to a moisture content of 65%;

[0026] (2) Preparation of fermentation equipment: establish an airtight fermentation room, and ensure that the roof of the fermentation room is transparent. Set up multiple side-by-side primary fermentation tanks and multiple side-by-side secondary fermentation tanks in the airtight fermentation room. A number of oxygenation pipes are buried on the bottom and four inner side walls, and the top of the oxygenation pipe facing the cavity in the fermenter is opened with a number of pores, and the pores are connected with the cavity in the fermenter. The pump transports air or oxygen to the oxygenation pipeline; a negative pressure exhaust pipeline is connected to the top of the sealed fermentation chamber, and the other en...

Abstract

The invention discloses a closed solid-state continuous chicken manure organic fertilizer fermentation method. The method is realized through the steps of moisture control, fermentation equipment preparation, primary fermentation, secondary fermentation, after-ripening and the like. According to the invention, the foul smell of chicken manure can be effectively prevented from polluting the surrounding environment in the fermentation process, and the problem that the chicken manure is burnt out due to overhigh fermentation temperature caused by closed fermentation is effectively improved.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer preparation, in particular to a closed-type solid-state continuous chicken manure organic fertilizer fermentation method. Background technique [0002] Chicken manure is a relatively high-quality organic fertilizer, which contains about 1.63%, 1.54%, and 0.085% of pure nitrogen, phosphorus (P2O5), and potassium (K2O). Chicken manure must be decomposed with a decomposing agent before application, and the parasites and their eggs in the chicken manure, as well as some infectious bacteria, will be inactivated and deodorized through the process of decomposing. The chicken manure fermentation in the prior art mainly adopts the mode of disposable composting and fermenting, and is open stacking. The fermentation conditions of this fermentation method are not easy to master, and the odor during the fermentation process will affect the surrounding environment. In addition, because the fermenta...
