Embodiment 1

[0031] A method for preparing biomass fuel with fresh pig manure as the main raw material, comprising the following steps:

[0032] 1) Raw material pretreatment: crush the discarded mushroom sticks and dry them naturally to make the moisture content lower than 10wt% to prepare the mushroom sticks for use; Moisture content is lower than 10wt%, makes branch and leaf spare material;

[0033] 2) Fermentation: Mix 65wt% of fresh pig manure, 25wt% of mushroom stick material and 10wt% of branch and leaf material to prepare a mixture; Brachybacterium fecium , Bacillus megaterium Bacillus megaterium Aspergillus oryzae Aspergillus oryzae , Bacillus licheniformis Bacillus licheniformis and Streptomyces griseus Streptomyces griseus Composite according to the mass ratio of 2:15:6:2:3), the addition amount is 5% of the raw material weight, and the first composting fermentation is carried out. The fermentation cycle is 5 days, and the composting is turned once every 3 days to make...

Embodiment 2

[0041] A method for preparing biomass fuel with fresh pig manure as the main raw material, comprising the following steps:

[0042] 1) Pretreatment of mushroom sticks: crushing discarded mushroom sticks and drying them naturally to make the moisture content lower than 10wt% to prepare spare mushroom sticks;

[0043] 2) Fermentation: Mix 75wt% of fresh pig manure and 25wt% of mushroom sticks to make a mixture; then add deodorizing compound microorganisms (by Brevibacter faecalis Brachybacterium fecium , Bacillus megaterium Bacillus megaterium Aspergillus oryzae Aspergillus oryzae , Bacillus licheniformis Bacillus licheniformis and Streptomyces griseus Streptomyces griseus Composite according to the mass ratio of 4:10:8:1:4), the addition amount is 10% of the raw material weight, and the first composting fermentation is carried out. The fermentation cycle is 7 days, and the composting is turned once every 3 days to make the mixed The water content of the material is r...

Embodiment 3

[0051] A method for preparing biomass fuel with fresh pig manure as the main raw material, comprising the following steps:

[0052] 1) Mushroom stick pretreatment: crush the discarded mushroom sticks and dry them naturally to make the water content lower than 10wt%, so as to prepare the spare mushroom sticks; crush the waste of branches and leaves from garden pruning, and dry them naturally. Make its moisture content lower than 10wt%, make branch and leaf spare material;

[0053] 2) Fermentation: Mix 70wt% of fresh pig manure, 25wt% of mushroom stick material and 5wt% of branch and leaf material to prepare a mixture; Brachybacterium fecium , Bacillus megaterium Bacillus megaterium Aspergillus oryzae Aspergillus oryzae , Bacillus licheniformis Bacillus licheniformis and Streptomyces griseus Streptomyces griseus Composite according to the mass ratio of 3:12:7:1:3), the addition amount is 4% of the weight of the mixture, and the first composting fermentation is carried...

Abstract

The invention belongs to the technical field of environmental protection, and particularly relates to a method for preparing biomass fuel by taking fresh pig manure as a main raw material. The method particularly comprises the following steps that 1, raw materials are pretreated; 2, fermentation is conducted, wherein the fresh pig manure, fungus mushroom rods and / or branch and leaf materials are mixed, and an obtained mixture is inoculated with deodorant compound microorganisms for first-time fermentation and then inoculated with nitrogen fixation-desulfuration compound microorganisms for second-time fermentation; 3, fermented materials are naturally air-dried; 4, tea stalk materials are added, and extruding granulation is conducted. The biomass pellet fuel which is low in ignition point and high in combustion heat value and combustion rate is prepared by taking the fresh pig manure as the main raw material, taking the waste fungus mushroom rods and the tea stalks as auxiliary materials, adding the deodorant compound microorganisms and the desulfuration compound microorganisms, fully utilizing the efficient deodorization property of the compound microorganisms and enhancing the flammability and the comprehensive combustion characteristic of the materials. According to the method, the pig manure can be greatly consumed, the environmental pollution problem of the pig manure is solved, and meanwhile the direction is provided for recycling utilization of the waste fungus mushroom rods and the tea stalks.

Description

technical field [0001] The invention belongs to the technical field of new energy fuel and environmental protection, and in particular relates to a method for preparing biomass fuel by using fresh pig manure as a main raw material. Background technique [0002] The large-scale development of my country's aquaculture industry has made a significant contribution to the enrichment of the "vegetable basket" project. At the same time, a large number of aquaculture pollutants, especially solid fecal pollutants, have become a key technical bottleneck restricting the sustainable development of the aquaculture industry, affecting healthy aquaculture. and potential risks to the environment. The traditional treatment method is through anaerobic technology and supporting related post-treatment technology, most of which are mainly "resource utilization in mountains, forests or fields". The effect and processing stability are poor and management is inconvenient. In recent years, the trea...
