Embodiment 1

[0034] Take 5000Kg of fresh farmed chicken manure, put it in a container at 100-110°C, keep it warm for 60-70min, and the sterilization is completed; measure the solid weight contained in the sterilized chicken manure, and the quantitative standard for the solid content of chicken manure is the solid-liquid ratio: Water 1: solid matter 2.5~3, use H 2 SO 4 or H 3 PO 4 The pH value of the acidification is between 3.5 and 5.0, and the chicken manure is acidified and diluted with an aqueous solution, the solid-liquid ratio is 1:2.5, and then H 2 SO 4 or H 3 PO 4 Adjust the pH value to 3.5, and add 0.5% Saccharomyces cerevisiae, 0.2% glucoamylase and 0.4% acid protease to the diluted material at a temperature of 25°C according to the measured solid weight in the sterilized chicken manure, stir and mix Evenly, put it into a fermentation container, increase the temperature by 5°C based on the temperature when adding Saccharomyces cerevisiae, glucoamylase and acid protease in th...

Embodiment 2

[0036] Take 5000Kg of fresh farmed chicken manure, put it in a container at 100-105°C, keep it warm for 60-65min~, after the sterilization is completed, measure the solid weight contained in the sterilized chicken manure, and use H 2 SO 4 or H 3 PO 4 The pH value of the acidification is between 3.5 and 5.0, and the chicken manure is acidified and diluted with an aqueous solution, the solid-liquid ratio is 1:3.0, and then H 2 SO 4 or H 3 PO 4 Adjust the pH value to 4.0, and add 0.6% Saccharomyces cerevisiae, 0.4% glucoamylase and 0.5% acid protease according to the solid weight contained in the sterilized chicken manure to the diluted material at a temperature of 30°C, stir and mix Evenly, put it into a fermentation container, increase the temperature by 8°C based on the temperature when adding Saccharomyces cerevisiae, glucoamylase and acid protease in the early stage, and keep it warm at 35°C, through the synergistic effect of Saccharomyces cerevisiae, glucoamylase and a...

Embodiment 3

[0038] Take 5000Kg of fresh farmed chicken manure, put it in a heating container and raise the temperature to 100-103°C, keep it warm for 60-65min~, after the sterilization is completed, measure the solid weight contained in the sterilized chicken manure, use H 2 SO 4 or H 3 PO 4 The acidified pH value is between 3.5 and 5.0, and the aqueous solution is acidified and diluted, and the solid-to-liquid ratio is 1:3.5, and then H 2 SO 4 or H 3 PO 4 Adjust the pH value to 4.0, and add 0.6% Saccharomyces cerevisiae, 0.3% glucoamylase and 0.5% acid protease to the diluted material at a temperature of 30°C according to the measured solid weight in the sterilized chicken manure, and stir Mix evenly, put it into a fermentation container, increase the temperature by 5°C based on the temperature when adding Saccharomyces cerevisiae, glucoamylase and acid protease in the early stage, and keep it warm at 35°C, through the synergistic effect of Saccharomyces cerevisiae, glucoamylase and...

Abstract

The invention discloses a method for controlling breeding chicken manure environmental pollution by virtue of a fermented wine making method. The method is characterized by comprising the following steps: sterilizing chicken manure: preserving heat in a sealed container at 100-110 DEG C for 60-80min; acidifying and diluting the chicken manure by virtue of an H2SO4 or H3PO4 water solution at a solid-to-liquid ratio of 1 to (2.5-5.0), and regulating pH value to 3.5-5.0 by virtue of H2SO4 or H3PO4; adding 0.2-0.8% of saccharomyces cerevisiae, 0.2-0.6% of saccharifying enzyme and 0.3-1.2% of acid protease according to the determined weight of solid in the sterilized chicken manure when materials are at 25-30 DEG C, conducting stirring for several times and implementing fermentation at 30-38 DEG C; adding Ca(OH)2, regulating pH value to 6.5-7.0 and separating a first solid from fermenting mash; distilling the fermenting mash so as to obtain ethanol-containing liquid, and rectifying the ethanol-containing liquid so as to obtain ethanol, wherein the rest part in the fermenting mash is a base solution; and concentrating the base solution so as to obtain a second solid, and adding the second solid to the first solid, so that organic fertilizer is obtained, wherein according to the method, the ethanol and CO2 gas are generated, and generated water, namely distilled water, can be repeatedly utilized and discharged.

Description

technical field [0001] The invention relates to the field of environmental treatment of animal husbandry wastes, in particular to a method for treating environmental pollution of chicken manure by using fermentation and brewing, using cultured chicken manure as a raw material, and using chemistry, biology and engineering as the basis. Background technique [0002] The pollution of chicken manure is not only a serious problem faced by developed countries and regions of animal husbandry, but also an environmental problem that developing countries of animal husbandry should focus on. The typical incidents of severe environmental pollution caused by animal husbandry developed countries such as the Netherlands and the United States have become a lesson for the past. [0003] Because the chicken's digestive tract is short, and chickens have no lips, no teeth, and crop secretions have no digestion ability, the residence time of feed passing through the intestine is short, especiall...
