Method for processing organic fertilizer by utilizing agricultural wastes

Abstract

The invention discloses a method for processing organic fertilizer by utilizing agricultural wastes. The method comprises the following steps: preprocessing the wastes, preparing a vermiculite fermenting agent, feeding to form fermentation heaps and carrying out fermentation. The processing of the wastes comprises the following steps: pulverizing solids in agricultural wastes and uniformly mixingthe solids to obtain solid wastes; using liquid in the agricultural wastes as liquid waste for storage and subsequent use; preparation of the vermiculite fermenting agent comprises the following steps: mixing ferment bacteria with expanded vermiculite to obtain the vermiculite fermenting agent; the fermentation heaps comprise multiple fermentation layers sequentially arranged in the height direction, wherein the fermentation layers comprises: paving a layer of solid waste; then uniformly spraying liquid waste on the solid waste until the humidity of the solid waste reaches a predetermined value, and uniformly putting the vermiculite fermenting agent on the solid waste. According to the method disclosed by the invention, the agricultural wastes are made into organic fertilizer, so that theproblems that atmosphere pollution caused by the agricultural wastes is effectively solved, underground water source pollution and carbon emission pollution are effectively solved, and the surface source pollution program is effectively solved.

Description

technical field [0001] The invention relates to the technical field of agricultural waste treatment, in particular to a method for processing organic fertilizers by using agricultural waste. Background technique [0002] At present, in our country, there is no positive and effective method for the post-processing of agricultural waste, such as straw waste, breeding waste, etc. For straw waste, in agricultural production, straw such as apples, corn, wheat, etc. Some of them are disposed of by incineration and other methods, causing serious air pollution, and some of them are randomly piled in the fields, near rural roads, etc., and long-term piles breed many harmful bacteria. For farming waste, rural farms are mostly farmed by individual households, and poultry manure cannot be disposed of in a timely manner. The stench formed seriously affects people's quality of life. At the same time, the water in the manure continues to infiltrate, causing great pollution to groundwater s...

Problems solved by technology

[0002] At present, in our country, there is no positive and effective method for the post-processing of agricultural waste, such as straw waste, breeding waste, etc. For straw waste, in agricultural production, straw such as apples, corn, wheat, etc. Some of them are disposed of by incineration and other methods, causing serious air pollution, and some are randomly piled in fields, near rural roads, etc., and long-term stacking breeds many harmful bacteria

For farming waste, rural farms are mostly farmed by individual households, and livestock manure cannot be disposed of in time, and the stench formed seriously affects people's quality of life. At the same time, the water in the manure continues to infiltrate, causing great pollution to groundwater sources.
