Abstract

The invention relates to an efficient heat-increasing compost self-heating particle as well as a preparation method and application thereof, belongs to the technical field of garbage treatment, and solves the technical problems of short duration time of a high-temperature fermentation period and long fermentation period of a traditional aerobic composting method, and adopts the technical scheme that the self-heating particle sequentially comprises a core porous ceramic ball core, a shell layer and a film layer from inside to outside, the self-heating particles are composed of rubidium-iron-boron magnetic powder, charcoal, a cementing agent, a mesophilic microbial agent, a facultative thermophilic microbial agent, a modified pore-forming agent, a cross-linking agent, a coating material and a kaolin base material. Moreover, the invention also provides a preparation method and application of the self-heating particles, organic matters in garbage materials are fully utilized, the high-temperature period of garbage composting is prolonged, the self-heating particles are added in the beginning period of composting, the activity of thermophilic microorganisms in the self-heating particles is enhanced, the temperature loss speed is slowed down, and the high-temperature reaction time of the materials is maintained; decomposition and mineralization of organic matters in garbage materials are accelerated, the fermentation period is shortened, and a new thought is provided for garbage composting.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a high-efficiency heat-increasing type compost self-heating granule and its preparation method and application. Background technique [0002] With the improvement of my country's urbanization level, the amount of garbage generated continues to increase, and the phenomenon of "garbage siege" is becoming more and more obvious. More and more researchers are paying attention to issues related to garbage disposal. At present, the methods of waste treatment mainly include anaerobic composting, aerobic composting, anaerobic-aerobic combined composting, pyrolysis, incineration and sanitary landfill. Among them, the aerobic composting method has the advantages of low processing cost and simple operation. However, the traditional aerobic composting method has the disadvantages of short duration of fermentation high temperature period and long fermentation period. C...
