Embodiment 1

[0055] (1) Biomass sludge preparation:

[0056] 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 the separated hemicellulose is in the liquid phase, that is, the hemicellulose liquid;

[0057] The hemicellulose liquid enters the wastewater treatment system and undergoes the pretreatment stage, biochemical treatment stage and advanced treatment stage successively. The pretreatment stage removes suspended solids to produce primary sludge, and the biochemical treatment stage removes a large amount of soluble COD to produce residual activated sludge. The treatment stage removes a small amount of pollutants that are not easily biodegradable to produce chemical sludge;

[0058] The primary sludge, residual activated sludge and chemical sludge are mixed, concentrated, flocculated, dehydrated, ventilated in the particle workshop, and dried to avoid d...

Abstract

The invention belongs to the technical field of sludge treatment in biomass resource comprehensive utilization, and more specifically relates to a method used for preparing a high-activity humic acid clear solution. The method comprises following steps: preparation of biomass sludge; preparation of extracting agents; preparation of auxiliary extracting agents; extraction of humic acid; separation; preparation of a humic acid clear solution; and activation of the humic acid clear solution. According to the method, biomass sludge generated in biomass resource comprehensive utilization is taken as a raw material; sodium tripolyphosphate, potassium hydrogen phthalate, and potassium hydroxide are taken as the extracting agents; potassium hydrogen phthalate, ethanol, and glycerin are taken as the auxiliary extracting agents; the method is capable of solving problems in the prior art that extraction temperature is high, a part of physiological activity is destroyed, energy consumption is high, and heavy metal is introduced; polyaspartic acid is added to increase the activity of the humic acid clear solution; and the content of humic acid in biomass sludge is high, so that extraction of humic acid from biomass sludge is capable of saving natural resource, and realizing biomass sludge reduction, stabilization, hazard-free treatment, and resourceful treatment.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment in the comprehensive utilization of biomass resources, and in particular relates to a method for preparing a high-activity humic acid serum. Background technique [0002] A large amount of biomass sludge is produced in the comprehensive utilization of biomass resources and papermaking industries. The existence of these sludges brings a huge burden to the ecological environment, and at the same time brings about the reduction, stabilization, harmlessness and environmental protection of sludge. The problem of resource utilization is becoming more and more serious. To this end, the country has also issued a series of policies and plans to promote and promote the industrialization and marketization of my country's sludge treatment technologies and processes. Sludge treatment will receive more and more attention, and is expected to enter a stage of rapid growth driven by policies. However, i...
