Novel environment-friendly domestic garbage treatment method

Abstract

The invention relates to the technical field of garbage treatment, in particular to a novel environment-friendly domestic garbage treatment method. According to the method, domestic garbage is subjected to graded stirring treatment, according to different densities of the domestic garbage, the domestic garbage is pre-divided into two types of metal sandstone garbage and organic plastic garbage, the organic plastic garbage is preliminarily extruded and dehydrated and then sprayed with bacterial liquid for fermentation, organic perishable substances are further decomposed through bacteria in thefermentation process, the organic perishable substances can be further dried, the odor of a working workshop can be effectively reduced through fermentation and decomposition under a low water content environment, the environment of a treatment workshop is improved, organic matters in the micro-carbonized organic garbage are subjected to anaerobic pyrolysis through a pyrolysis furnace, extractedpyrolysis gas can be stored in a gas storage tank to be used as fuel gas, efficient resource conversion is carried out on the domestic garbage, and the method has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a novel environmental-friendly domestic garbage treatment method. Background technique [0002] With the rapid development of economy, the continuous growth of population and the improvement of people's living standards, the generation of domestic waste has also increased sharply, which has caused a great burden on the environment. There are many methods of garbage disposal, such as landfill, composting and incineration, which are relatively mature methods. Garbage pyrolysis treatment has attracted widespread attention due to its high energy recovery rate and low pollution. The pyrolysis method will become a very promising garbage treatment method to replace traditional garbage treatment methods. Biomass pyrolysis (also known as pyrolysis or cracking), usually refers to the process in which biomass is heated and heated to cause molecular decomposition to produce coke, ...

Problems solved by technology

[0003] In China, affected by the living habits of residents, the moisture content of domestic waste is very high, which increases the adhesion between different materials and makes the separation efficiency of light and heavy materials, organic matter and inert materials low. The process route for RDF preparation It is extremely difficult to formulate and select equipment, and the removal of water will increase the energy consumption of the system, seriously affecting the economic benefits and sustainability of solid waste resource disposal

In addition, domestic waste contains a large amount of perishable organic matter, which will naturally ferment during the storage and pretreatment process, resulting in stench, especially dynamic fermentation and semi-dynamic fermentation, which need to be turned over, the processing cost is high, and it is difficult to achieve complete airtightness. It is easy to cause secondary pollution, the working environment is relatively bad, and the resource conversion efficiency of domestic waste is low
