Embodiment Construction

[0021] The present invention will be described in further detail below, so that those skilled in the art can implement it with reference to the description.

[0022] The invention provides a method for preparing fertilizer from mixed animal manure, comprising:

[0023] Step 1. Put 1 part of mixed animal manure, 0.5 part of calcium oxide and 15 parts of water in the pool by mass parts, stir for 20 minutes, adjust the pH value to 6-7 with 1 mol / L citric acid, add 0.5 parts of EM bacteria, stirred for 3 to 4 minutes, and stood still for 10 hours to obtain a mixture; each part of mixed animal manure includes chicken manure, cow manure, rabbit manure, pig manure and sheep manure with a mass ratio of 1:10:0.5:2:1 . (Calcium oxide is used for preliminary deodorization of animal feces. Use citric acid to adjust the pH value of the feces to the range suitable for the action of EM bacteria. Citric acid is an organic acid, non-toxic, does not introduce other ions, and is safe and green....

Abstract

The invention discloses a method for preparing a fertilizer from mixed animal manure, which comprises the following steps: mixing mixed animal manure, calcium oxide and water, regulating the pH value, and adding 0.5 part of effective microorganisms to obtain a mixture; regulating the pH value to 8, adding neutral proteinase, and carrying out enzymolysis; steaming the mixture at 120 DEG C under 1.5 atmospheric pressures; pulverizing the mixture four times; putting a seaweed-containing sealed box in the mixture, standing for 15 minutes, and taking out the box; regulating the pH value of the mixture to 5, adding lactobacillus, and carrying out anaerobic fermentation; adding yucca, fructus momordicae, oyster shell, effective microorganisms and straw feed ferment into the mixture, and carrying out anaerobic fermentation; adding a manure ferment into the mixture, and carrying out anaerobic fermentation; and steaming the mixture at 90 DEG C under 1.2 atmospheric pressures for 5 minutes, relieving to one atmosphere, cooling the mixture to 15 DEG C, and adding 0.005 part of nano carbon into the mixture. The fertilizer prepared by the method has high fertility, and is free of malignant bacteria and pests.

Description

technical field [0001] The invention relates to manure fermentation, in particular to a method for preparing fertilizer from mixed animal manure. Background technique [0002] With the development of our country's economy, our country's animal husbandry has developed by leaps and bounds. However, with the development of animal husbandry, the feces excreted by animals have brought serious problems, which not only cause stench in the air, spread diseases, but also seriously pollute the environment. To solve the problem of animal manure, the main method is to ferment manure as agricultural fertilizer or as biofuel; the commonly used fermentation method is mainly fermenting bacteria, using anaerobic and aerobic fermentation, but it often causes bacterial pollution and incomplete fermentation. Contents of the invention [0003] Aiming at the problems existing in the fermentation of animal manure at present, the present invention designs and develops a method for preparing fer...
