Preparation method for preparing organic fertilizer through cow dung

Abstract

The invention relates to a preparation method for preparing organic fertilizer through cow dung. The preparation method comprises the following methods of cutting waste straw into sections; then adding the cut straw sections into fresh cow dung, adding the defined amount of urine, evenly mixing, adding the defined amount of leavening agent into an initially-fermented material, putting the material into a methane tank to be fermented for the second time to form methane and methane slag, filtering the fermented methane slag, taking out the methane slag and drying; putting to a normal temperature, then smashing and packaging to obtain the organic fertilizer. The methane can be used as residential energy resources. In an implementation process of the preparation method for preparing organic fertilizer through cow dung, the cow dung is fermented to be used as methane. Thus, the problem of residential energy resources of people is solved, and the methane slag can be processed into the organic fertilizer. The organic fertilizer can be widely applied to planting industry, the use of a lot of chemical fertilizer is reduced, the soil is loosened, and the soil is more fertile.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a method for preparing organic fertilizer from cow dung. Background technique [0002] With the continuous development of my country's large-scale livestock and poultry breeding industry, the production of livestock and poultry manure is also increasing. If a large amount of livestock and poultry manure is not treated in a harmless manner after production, it will not only produce malodorous gas, but also cause serious environmental pollution. Pollution can also breed mosquitoes and lead to the widespread spread of pathogenic bacteria, threatening human health. The feces produced in the breeding process of animal husbandry need to be treated in a reasonable way; at the same time, if the cow dung is not properly handled, it is likely to cause serious disease risk problems in the breeding industry. Therefore, the treatment of cow dung has become a constraint on the dev...

The feces produced in the breeding process of animal husbandry need to be treated in a reasonable way; at the same time, if the cow dung is not properly handled, it is likely to cause serious disease risk problems in the breeding industry. Therefore, the treatment of cow dung has become a constraint on the development of animal husbandry in my country. important factor, and even triggered a serious public health security crisis
