Embodiment 1

[0025] A preparation method for producing organic fertilizer by absorbing pig manure with organic waste, mixing pig manure and waste water from flushing pig houses with the prepared adsorption material to make organic fertilizer fermentation raw material; then transporting the organic fertilizer fermentation raw material to compost workshop for composting; then send the composted material to the fermentation workshop for high-temperature aerobic fermentation to make organic fertilizer; its characteristic is that the adsorption material is organic waste as the adsorption raw material, and beneficial bacteria are added to the adsorption raw material It is a material with adsorption capacity after primary fermentation is carried out in the auxiliary material storage workshop to remove excess water in the adsorption raw material; the mixing of pig manure and waste water from flushing the pig house with the prepared adsorption material is to mix the pig manure with the waste water fr...

Embodiment 2

[0037] The basic principle of the second embodiment is the same as that of the first embodiment, except that the formula and the ratio adopted are different. It is a preparation method of using organic waste to absorb pig manure to produce organic fertilizer. The waste water from the house is mixed with the prepared adsorption material to make organic fertilizer fermentation raw materials; then the organic fertilizer fermentation raw materials are transported to the composting workshop for composting; and then the composted materials are sent to the fermentation workshop for high-temperature aerobic fermentation to make organic fertilizers; It is characterized in that the adsorption material is a material that uses organic waste as the adsorption raw material, adds beneficial bacteria to the adsorption raw material, and performs primary fermentation in the auxiliary material storage workshop to remove excess water in the adsorption raw material and has adsorption capacity; The ...

Embodiment 3

[0049] The basic principle of Example 3 is the same as that of Example 1, except that the formula and proportion adopted are different. It is a preparation method of using organic waste to absorb pig manure to produce organic fertilizer. The waste water from the house is mixed with the prepared adsorption material to make organic fertilizer fermentation raw materials; then the organic fertilizer fermentation raw materials are transported to the composting workshop for composting; and then the composted materials are sent to the fermentation workshop for high-temperature aerobic fermentation to make organic fertilizers; It is characterized in that the adsorption material is a material that uses organic waste as the adsorption raw material, adds beneficial bacteria to the adsorption raw material, and performs primary fermentation in the auxiliary material storage workshop to remove excess water in the adsorption raw material and has adsorption capacity; The method of mixing pig f...

Abstract

The invention discloses a preparation method for producing organic fertilizer by use of organic waste to adsorb pig excrement. The method comprises the following steps: collecting pig excrement and wastewater for washing a hog house to a collecting pool to form excrement; taking organic waste as an adsorption raw material, and adding probiotics in the adsorption raw material to perform primary fermentation, thereby forming an adsorption material after removing excessive moisture in the adsorption raw material; mixing the excrement and the adsorption material in a proportion of 1:(2-3), and sufficiently blending through a material mixer to prepare a fermentation raw material; conveying the fermentation raw material to a compost workshop to perform compost treatment according to a compost production process; and then conveying the composted material to a fermentation workshop to perform high-temperature aerobic fermentation through temperature control and humidity control fermentation, thereby preparing the organic fertilizer. The raw materials of the invention all adopt the waste materials, so that the aims of dealing waste by waste and turning the waste into wealth are achieved, and secondary pollution can be avoided.

Description

technical field [0001] The invention relates to a method for preparing organic fertilizer, in particular to a method for preparing organic fertilizer by absorbing pig manure with organic waste, and belongs to the field of organic fertilizer processing. Background technique [0002] After decades of rapid development, my country's pig industry has steadily ranked among the top in the world in terms of scale. However, the supply of pork cannot meet the needs of consumers, and meat products still need to be imported every year. With the development of the national economy and the demand of consumers, the domestic pig industry continues to grow, resulting in an increase in the discharge of pig wastewater and more and more serious environmental pollution. The current treatment of pig waste is too costly, even if a qualified treatment facility has been built, it has become a decoration due to the high operating cost. [0003] Pig manure is a very valuable resource. It contains va...
