Problems solved by technology

It is impossible to realize 100% recycling of garbage in the above three aspects of garbage recycling. For example, the utilization of waste products only accounts for about 10% of the total garbage, and 90% cannot be used; composting cannot be completely recycled, because the garbage Only about 40% is organic matter, and about 60% cannot be used as fertilizer, and the resource treatment is only about half; waste incineration power generation, due to the low calorific value of waste, it is difficult to use its heat energy alone to generate electricity, and must be incinerated When adding fuel oil and other combustion accelerants, this practice of using other energy sources to realize waste recycling is not only worth the loss, but also causes new pollution, and the value of recycling is degraded to a negative value

Embodiment 1

[0036] The domestic garbage handled in this embodiment is incremental garbage, which includes the following steps: garbage gathering (deodorization treatment), sorting (recycling recyclable waste), screening (screening large garbage crushed), high-temperature stack retting and aging (harmless treatment), crushing and stirring, briquetting or granulation, and shipment to desert areas.

[0037] Domestic waste processed into briquettes or pellets no longer has any characteristics of garbage. It is neither smelly nor dirty. It can be safely transported to desertification areas that need to be treated, and processed on the spot to make matrix materials for artificial vegetation. governance.

[0038] As for the disposal site of incremental garbage, the existing landfill site can be used as a site for sorting, stacking, fermenting, crushing, briquetting (granulating) and loading of garbage, so that new land can not be occupied.

[0039] The specific garbage disposal steps are as fol...

Embodiment 2

[0049] The domestic garbage handled in this embodiment is stock garbage, which has been stored in landfill or piled up for more than one year. It includes the following steps: digging, screening, crushing, stirring, briquetting (granulation), shipment, and transshipment to desertification areas.

[0050] Similarly, domestic waste processed into briquettes or pellets no longer has any characteristics of waste, and is neither smelly nor dirty. It can be safely transported to desertification areas that need to be treated, and processed on-site to make matrix materials for artificial vegetation. Control desertified land.

[0051] The specific garbage disposal steps are as follows (the sequence may be slightly adjusted depending on the situation):

[0052] Automatically sort out recyclable waste paper, waste plastics, and non-metals through air separation and magnetic separation belt, and recycle them;

[0053] Garbage after air separation and magnetic separation enters the scree...

Embodiment 3

[0060] The present embodiment adopts solid waste of domestic garbage and agriculture, forestry and animal husbandry to process, and its basic treatment steps are the same as embodiment 1, and its specific garbage treatment steps are as follows (sequence can be slightly adjusted depending on the situation):

[0061] The domestic garbage and other solid wastes will be accumulated for deodorization treatment;

[0062] High temperature fermentation by biochemical method;

[0063] Automatically sort out recyclable waste paper, waste plastics, and non-metals through air separation and magnetic separation belt, and recycle them;

[0064] Garbage after air separation and magnetic separation enters the screening belt, and the powdery garbage with particles smaller than 100 mesh is screened out and directly enters the mixing bin;

[0065] Garbage larger than 100 meshes enters the ball mill for ball milling, and all the garbage after ball milling becomes powdery, and enters the mixing c...

Abstract

The invention discloses a waste heterogenization and reclamation treatment method which is free of incineration and landfill. The method comprises the following steps of 1, harmless treatment of domestic waste and / or solid waste of agriculture, forestry and animal husbandry through a biochemical method; 2, heterogeneous treatment of the harmlessly treated waste through a physical method; 3, making the heterogeneously treated waste into blocky or granular new soil which is easy to transport and easy to lay; and 4, transporting the obtained high-quality new soil to a desert area for desert treatment. The method provides a waste treatment technology avoiding landfill and incineration and realizing heterogeneity and 100% reclamation.

Description

technical field [0001] The present invention relates to a garbage disposal method, more specifically, the present invention relates to a technique for heterogeneous treatment of garbage and resource utilization. Background technique [0002] With the growth of population and the rapid increase of urbanization rate, my country has become the world's largest waste country, with an annual output of 135 million tons of municipal solid waste, accounting for 1 / 4 of the world's total annual waste. Due to the backward means of garbage disposal, garbage piled up like mountains in many areas. At present, the stock of untreated garbage in the country has reached more than 6 billion tons, occupying more than 500 million square meters of land. my country's cities basically adopt the method of landfill and incineration for the disposal of garbage. In some areas, there are also random discarding methods such as "sea throwing" and "river throwing". The garbage pollutes the environment very...
