Process for preparing biomass fuel from domestic garbage and agricultural and forestry waste in rural areas

Abstract

The invention discloses a process for preparing biomass fuel from domestic garbage and agricultural and forestry waste in rural areas. Steps: The first step is landfill leachate treatment, odor deodorization; the second step is garbage screening, sorting, coarse crushing; the third step is non-organic magnetic separation, winnowing, and fine crushing; the fourth step is agricultural and forestry waste crushing, Screening; the fifth step, mixing combustible garbage, agricultural and forestry waste, sludge, and water, pressing and molding, and drying to make biomass fuel; the sixth step, adding the organic matter of garbage to livestock and poultry manure to make organic fertilizer. Biomass fuel can be directly used in boilers, and organic fertilizer solves the problem of environmental pollution caused by livestock and poultry manure in farms. The construction of a waste treatment plant requires less investment, low cost, and is easy to implement. Collect agricultural and forestry waste for a fee, increase farmers' income and reduce pollution. High profit margins, sustainable operation without government subsidies. Waste gas, waste liquid, and waste residue have all been treated in an environmentally friendly manner, and no new pollution will be generated.

Description

Technical field [0001] The present invention relates to a process of preparing biomass fuel, and more particularly to a process of preparing a biomass fuel in rural urban domestic garbage and agricultural forestry waste. Background technique [0002] Rural urban domestic garbage generally refers to the solid waste and laws and administrative regulations produced in the rural daily life or to provide services in rural daily lives. The pendulum waste mainly includes crop straw, weed, branches, leaves, tree roots, etc. As the population big country in developing countries, the number of villages and towns and the number of rural residents cannot be underestimated, so the necessary rural domestic garbage and agricultural forestry waste is to speed up township development and improve the quality of life quality of rural residents. At present, my country's rural domestic garbage and agricultural forestry waste treatment has mainly existing large quantities, complex garbage ingredients,...

AI Technical Summary

Problems solved by technology

At present, some people have invented and created related technical processes, but there are the following disadvantages: one is too much investment, too high cost, difficult to implement, and difficult to become a reality

Second, even if it can be implemented, due to high operating costs and negative profits, it will be difficult to operate sustainably without government subsidies

The third is that only rural and urban domestic waste has been treated, while a large amount of agricultural and forestry waste has not been treated and recycled, and a large part is missing, failing to achieve the purpose and effect of fundamental treatment
