Integrated process and system for resourceful treatment for household garbage

Abstract

The invention discloses an integrated process and system for resourceful treatment for household garbage. The integrated process for the resourceful treatment for the household garbage comprises the following steps: carrying out garbage sorting; carrying out recovery and reutilization on a part of the sorted materials; carrying out deep fermentation conversion and utilization on the sorted organicmaterials and a leachate; carrying out marsh gas power generation on biogas generated due to fermentation; preparing a solid organic fertilizer from biogas residue; and carrying out sewage treatmenton biogas slurry and then recycling. The integrated process and system for the resourceful treatment for the household garbage have the advantages of being pollution-free, harmless, and capable of carrying out complete resourceful treatment on the household garbage; the sorted organic matters are fermented at first, and the biogas with high combustion efficiency is generated for power generation,so that the power generation efficiency is increased, and the emission of harmful gases is greatly reduced; and the biogas residue and the biogas slurry are also correspondingly subjected to deep productization treatment, and sold for subsidizing the related expense generated due to the household garbage treatment, so that the financial expenditure of government operation for a garbage treatment plant is reduced, and reduced, resourceful and harmless treatment is much effectively carried out on the household garbage.

Description

technical field [0001] The invention relates to the technical field of domestic waste resource treatment, in particular to an integrated process and system for domestic waste resource treatment. Background technique [0002] At present, domestic and foreign domestic waste treatment technologies are all aimed at harmlessness, reduction, and recycling. The most commonly used treatment methods are landfill, incineration and composting. They have different application scopes and conditions. So far , the domestic waste treatment has not yet achieved the purpose of all resource treatment, and the resource treatment has only reached about 20% of the total domestic waste, while the residual materials are basically still in the state of landfill and incineration after treatment, and there are still increasing landfill Land use and environmental pollution issues. Contents of the invention [0003] The object of the present invention is to overcome the defects in the prior art and p...
