Energy-saving buried kitchen waste treatment system

Technical Field

The invention relates to the field of garbage disposal system equipment, in particular to an energy-saving buried kitchen garbage disposal system.

Background

The kitchen garbage belongs to organic household garbage, has complex components, mainly comprises rice and flour food residues, vegetables, fishbones, meat bones, shellfish, animal and vegetable oil, a small amount of toothpicks, waste tableware, paper towels, plastics and the like, has chemical components of starch, cellulose, protein and inorganic salt and the like, and has the characteristics of large weight, high water content, high organic matter content and easy biodegradation, and the water accounts for 80-90 percent of the total weight of the garbage.

Therefore, the kitchen waste is not suitable to be treated by adopting an incineration method, and is preferably treated by adopting a microbial decomposition method. The anaerobic fermentation technology is the mainstream technology of kitchen waste treatment in the industry at present, and the principle of the technology is that organic matters in the kitchen waste are degraded into micromolecular substances from macromolecular substances under the action of anaerobic bacteria and under the condition of proper temperature, and finally the micromolecular substances are fermented, degraded and converted into methane. The methane generated after fermentation contains 55-75% (volume concentration) of methane, and can be used for power generation, heat supply and the like. Simultaneously, the degradation results in the inclusion of the active ingredients. The proportion of treatment facilities for treating the kitchen waste by applying the anaerobic fermentation technology in the industry is up to 80 percent. The technology for producing the biogas by treating the kitchen waste through anaerobic fermentation is quite mature, the technology is quite reliable, and the technology becomes an absolute mainstream technology of the current kitchen waste treatment industry.
