Method for preparing ecological organic crude fertilizer through rapid degradation of livestock and poultry wastes

Abstract

The invention belongs to the field of preparation methods of organic fertilizers, and discloses a method for preparing an ecological organic crude fertilizer through rapid degradation of livestock and poultry wastes. The method comprises the following steps: (1) conditioning the wastes: adding an organic conditioner and an inorganic modifier sequentially into the livestock and poultry wastes, and uniformly stirring to obtain a mixture I; (2) adding bacteria: heating the mixture I obtained in the step (1) to raise the internal temperature of the mixture I, and adding the degrading bacteria to obtain a mixture II; (3) performing assistant fermentation: heating and stirring the mixture II, and forcibly convecting the mixture II till the moisture content of the mixture II reaches 30-40%, so as to obtain the organic crude fertilizer. With the method provided by the invention, the dehydration characteristics of the livestock and poultry wastes can be effectively improved, heavy metals are fixed and antibiotics are oxidized; organic matters and crude fiber in the livestock and poultry wastes and the organic conditioner can be utilized and decomposed by the degrading bacteria within a short time, so that bound water is easier to remove.

Description

technical field [0001] The invention belongs to the field of organic fertilizer preparation methods, and more specifically relates to a method for ecological organic rough fertilizer. Background technique [0002] At present, China's livestock and poultry industry has entered the stage of modern development, and the development of large-scale and intensive farms is showing a sharp upward trend. The production of a large amount of meat, egg and milk products is accompanied by a large amount of livestock and poultry waste. This kind of waste contains a large number of pathogenic microorganisms and parasite eggs, as well as exogenous chemicals such as antibiotics and heavy metals. If not properly treated, it will cause serious pollution to the surrounding waters and soil. At the same time, this type of waste is rich in a large amount of organic matter and nitrogen and phosphorus nutrients, and has a high degree of resource utilization. [0003] Composting is an effective utili...
