Abstract

The invention relates to a technology and a process for treating organic solid waste through self-balancing fermentation and incineration. According to the technology, organic solid waste is adopted to cooperate with anaerobic fermentation, biogas generated after fermentation is purified and then used by a subsequent incineration system, and remaining yeast residues (containing yeast liquid) are mixed with a certain amount of auxiliary materials and then incinerated. Due to the fact that the materials are fully fermented before incineration, macromolecular combustible components in the materials are converted into micromolecular fuel, the utilization efficiency of the energy conversion process is improved, part of the generated biogas can cover fuel consumption needed by the system, part of the generated biogas is used for power consumption of a power generation coverable system, and therefore self-balancing of system energy is achieved.

Description

technical field [0001] The invention relates to an organic solid waste treatment technology, in particular to a self-balanced fermentation and incineration technology and process for organic solid waste treatment. Background technique [0002] With the advancement of urbanization and the improvement of people's living standards, the generation of municipal sludge and organic solid waste in cities and counties at all levels has increased year by year. According to the data from the 2019 National Symposium on Organic Solid Waste Treatment and Resource Utilization, there are still 1.782 billion tons of residues after municipal sludge and organic solid waste recycling. Valuable landfill space. At the same time, due to the natural fermentation of sludge and organic solid waste, there are potential safety hazards in landfills, resulting in waste of organic matter and more serious environmental pollution. It is urgent to improve the technology, standardization and resources of orga...
