Problems solved by technology

If it is used as fertilizer directly, there are many disadvantages: (1) The long-term balanced output of manure is inconsistent with the seasonality of agricultural production. Fertilization is off-season, so it has to be piled up outside to let the wind and rain drench, and the fertilizer effect will be lost; (2) Parasite eggs in manure , pathogens, and weed seeds are harmful to humans, livestock, crops, and the environment; (3) The heat and decomposition products produced by the fermentation of fresh manure in the soil have adverse effects on the growth and development of crops
Traditionally, the livestock and poultry manure is dried by sunlight, and the treated liv

Embodiment 1

[0014] Embodiment 1: A kind of livestock and poultry manure harmless treatment and biogas fermentation technology, its method is as follows:

[0015] (1) Use automatic manure cleaning facilities to clean up the livestock and poultry manure from the house, use a solid-liquid separator to dehydrate the manure, reduce the water content to below 20%, and then spray and disinfect the manure with 0.5% peracetic acid , and then mix the leaves, orange peel, and Angelica dahurica in a weight ratio of 3:2:1, and spray and deodorize the feces after water extraction. The total amount of the leaves, orange peel, and Angelica dahurica is 4% of the total livestock manure , keep the water content of the treated feces below 25% as much as possible for standby use;

[0016] (2) The following raw materials are crushed and passed through a 40-mesh sieve, and then mixed according to the weight ratio to form the fermentation auxiliary material. The raw materials for the fermentation auxiliary mater...

Embodiment 2

[0020] Embodiment 2: A kind of livestock and poultry manure harmless treatment and biogas fermentation technology, its method is as follows:

[0021] (1) Use automatic manure cleaning facilities to clean up livestock and poultry manure from the house, use a solid-liquid separator to dehydrate the manure, reduce the water content to below 20%, and then spray the manure with 0.2% peracetic acid for disinfection , and then mix Artemisia argyi leaves, orange peel, and Angelica dahurica in a weight ratio of 4:3:1, and spray and deodorize the feces after water extraction. , keep the water content of the treated feces below 25% as much as possible for standby use;

[0022] (2) The following raw materials are crushed and passed through a 50-mesh sieve, and then mixed according to the weight ratio to form the fermentation auxiliary material. The raw materials for the fermentation auxiliary material are: peanut shell 35, rape straw 46, apple leaf 27, sawdust 17, peat 15, blue-green alga...

Abstract

The invention discloses an animal manure innocent treatment and biogas fermentation technology. The technology comprises the steps of: mixing prepared animal manure and prepared fermenting auxiliaries according to the mixing ratio that addition amount of the fermenting auxiliaries are 25-35 percent of total amount of animal manure; inoculating the prepared EM bacteria into the mixture according to the inoculation quantity, regulating the water content of manure to be between 60-68 percent, dosing into a biogas digester to perform biogas anaerobic fermentation, and keeping the temperature of biogas fermentation to be between 20 and 40; constructing a stirring device on the biogas digester, and turning once every 5-7 days. When the biogas yield in the biogas digester is sharply decreased, the situation indicates that the animal manure is sufficiently decomposed and fermented. The technology has the characteristics of simple process and low cost, and can establish an 'animal-biogas manure-crops' innocent ecological environment, so that the breeding environment is purified, and the crop yield is increased.

Description

technical field [0001] The invention relates to the technical field of waste disposal and resource utilization, in particular to a technology of harmless treatment of livestock and poultry manure and biogas fermentation. Background technique [0002] With the rapid development of my country's economy and the improvement of people's living standards, human demand for animal-derived food is increasing. At present, my country's livestock and poultry breeding mode is gradually developing towards a large-scale, intensive and professional modern breeding mode. However, the expansion of production scale has brought great pressure to our living environment. The excretion of livestock and poultry manure is huge, causing harm and pollution. Surprisingly, the pathogenic microorganisms and mineral elements such as nitrogen and phosphorus contained in livestock and poultry manure have caused serious pollution to the environment on which human beings live, and at the same time, it is easy ...
