Embodiment 1

[0059] Preparation of highly active biological humic acid:

[0060] (1) After pretreatment, cutting and dust removal, the crop straw enters the separation section, where hemicellulose, cellulose and lignin are separated by physical and chemical methods, and straw light ash is produced. The separated hemicellulose and lignin The cellulose is the liquid phase, that is, the hemicellulose liquid and the lignin stock solution.

[0061] (2) Biomass sludge preparation:

[0062] The hemicellulose liquid enters the wastewater treatment system, removes suspended solids in the pretreatment stage to produce primary sludge, removes a large amount of soluble COD (chemical oxygen demand) in the biochemical treatment stage to produce residual activated sludge, and removes a small amount that is not easily biodegradable in the advanced treatment stage Pollutants produce chemical sludge. The primary sludge, remaining activated sludge and chemical sludge enter the sludge thickening tank and mi...

Abstract

The invention belongs to the technical field of comprehensive utilization of a biomass resource and relates to a preparation method of highly active biological humic acid. The method comprises pretreating forestry and agricultural residues, separating a hemicellulose liquid and a lignin stock solution, wherein the pretreatment step can produce light straw ash, preparing biomass sludge, preparing lignin, preparing a microbial starter diluent, uniformly mixing the biomass sludge, light straw ash and lignin, spraying the mixture with the microbial starter diluent, and carrying out fermentation to obtain highly active biological humic acid. The preparation method adopts the light straw ash, biomass sludge and lignin as raw materials produced in the process of high efficiency and comprehensive utilization of agricultural and forestry waste resources. The biological humic acid has high activity, can improve the efficiency of fertilizer and improve the soil, and can achieve the following indicators of fulvic acid content greater than or equal to 18%, functional bacterium content greater than or equal to 1.5*10<8> / g and moisture content less than or equal to 15% after low temperature drying. The functional bacteria are transformed into spores and can be preserved in a sealed environment for several months.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of biomass resources, and in particular relates to a preparation method of highly active biological humic acid. Background technique [0002] With the continuous improvement of the level of agricultural planting science and technology in our country and the continuous advancement of new rural construction, the quality of life of farmers has been greatly improved, and the quality of the living environment in rural areas has been improving day by day. The traditional way of utilizing agricultural and forestry wastes has also undergone obvious changes in the following aspects: Changes: chemical fertilizers are widely used due to the advantages of easy use and quick results, making agricultural and forestry wastes used as fertilizers in field production less important; the rapid popularization of modern commodity energy such as coal, electricity, and liquefied petroleum gas has replac...
