Method for preparing biomass raw material by utilizing kitchen residues

Abstract

The invention discloses a method for preparing a biomass raw material from kitchen residues, and the method comprises the following steps: sorting and filtering the kitchen residues, crushing, dehydrating and deoiling remains of selected animals and plants, uniformly mixing the obtained product with naturally aired crop straw small sections by adding water, adding strains, and performing fermenting, performing mixing and fermenting with yellow mud and animal dung, conducting dehydrating and curing, and grinding to form granules. According to the method for preparing the biomass raw material byutilizing the kitchen residues, the kitchen residues are treated by adopting a unique integral method, so that the cyclic utilization of kitchen wastes is realized, the fertilization structure is also improved, the biomass raw material is rich in humic acid, the fertility of the biomass raw material is improved, the biomass raw material prepared by the method can effectively promote the growth ofseedlings, the addition of the strains can improve mercury metal contaminated soil, the utilization rate of the soil is improved, the fertilizer efficiency of the prepared biomass raw material is maximum, and the method has huge popularization and application value.

Description

technical field [0001] The invention relates to the technical field of biomass raw material preparation, in particular to a method for preparing biomass raw material by using kitchen residues. Background technique [0002] Biomass raw material is a kind of biomass resource. Crop straw is a very valuable biomass energy resource in the agricultural ecosystem. There are many kinds of biomass in nature, widely distributed, and huge in quantity. , Human and animal manure and organic wastewater. [0003] Fertilizer is a kind of substance that provides one or more essential nutrient elements for plants, improves soil properties, and increases soil fertility. Chemical fertilizer is a widely used fertilizer for crops. When nitrogen, phosphorus, or potassium in the soil cannot meet When the growth of crops is needed, chemical fertilizers containing nitrogen, phosphorus or potassium can be applied. However, while chemical fertilizers increase crop yields, they also have a negative ef...

[0003] Fertilizer is a kind of substance that provides one or more essential nutrient elements for plants, improves soil properties, and increases soil fertility. Chemical fertilizer is a widely used fertilizer for crops. When nitrogen, phosphorus, or potassium in the soil cannot meet When the growth of crops is needed, chemical fertilizers containing nitrogen, phosphorus or potassium can be applied. However, while chemical fertilizers increase crop yields, they also have a negative effect on the soil. Most of the chemical fertilizers will introduce heavy metals in the preparation process, and the application of chemical fertilizers will cause soil pollution. Heavy metals and other toxic substances are added to the plant growth process. In addition to the need for crop photosynthesis to supply carbon nutrients, after using chemical fertilizers, it is also necessary to manually apply fertilizers to supplement other elements. In addition, most of the fertilizer effects of existing chemical fertilizers have not been used. , thus increasing agricultural costs, wasting energy and polluting the environment, therefore, we propose a method for preparing biomass raw materials from kitchen residues
