Organic solid waste zero-emission resource technology

Abstract

The invention discloses an organic solid waste zero-emission resource technology, which comprises the following steps: (1) pretreatment for making characteristics of organic solid waste materials homogeneous; (2) superfine grinding and refining for carrying out secondary grinding and refining on the materials and preliminarily damaging biomacromolecule cellular structure; and (3) low-temperature pyrohydrolysis for decomposing organic macromolecules of the organic solid wastes into micromolecular substances. By linking the superfine grinding and refining technology and the low-temperature pyrohydrolysis technology, the organic solid wastes are rapidly decomposed. The technology of the invention can replace the traditional aerobic fermentation and anaerobic fermentation process based on microbial action, and the disadvantage that the aerobic fermentation and anaerobic fermentation process is long, the process is hard to control and secondary pollutants are easy to produce are overcome. In addition, the whole processing and treatment process will not cause any secondary pollutants, organic fertilizers are produced, and resource utilization of organic solid wastes is realized.

Description

technical field [0001] The invention relates to a solid waste resource disposal process, in particular to a zero discharge and resource recovery process of organic solid waste. Background technique [0002] The traditional organic solid waste disposal method centered on aerobic composting fermentation technology and anaerobic fermentation biogas technology has secondary pollution (odor, peculiar smell, percolated sewage, excessive biogas slurry, etc.), backward process equipment, and disposal cycle Weaknesses such as long-term growth and inconspicuous economic benefits have been unable to meet the needs of the objective situation of resource disposal of organic solid waste. In terms of the secondary pollution caused by the technology itself, it is also difficult to pass the supervision of environmental protection monitoring, safety supervision, and health supervision departments. [0003] Therefore, how to develop a safe, efficient, and environmentally friendly organic soli...

Problems solved by technology

[0002] The traditional organic solid waste disposal method centered on aerobic composting fermentation technology and anaerobic fermentation biogas technology, due to its secondary pollution (odor, odor, percolation sewage, excessive biogas slurry, etc.), backward process equipment, and disposal cycle Weaknesses such as long-term and unobvious economic benefits can no longer meet the needs of the objective situation of resource disposal of organic solid waste

In terms of the secondary pollution caused by its technology itself, it is also difficult to pass the supervision of environmental protection monitoring, safety supervision, and health supervision departments.
