A solid-liquid separation fermentation treatment tank for township garbage

Abstract

The invention discloses a solid-liquid separation fermentation treatment tank for township garbage, which is equipped with a tank body, a top plate, a garbage discharge port, an air and liquid passage pipe, an air and liquid passage hole, a solid discharge port, a long rake, a V Shaped clapboard, dredging port, door panel, drain valve. The fermented garbage treatment tank is equipped with a V-shaped partition for supporting the garbage in the tank body. The garbage is thrown into the garbage treatment tank from the garbage injection port. The solid garbage is supported on the inclined partition. The solid garbage is fermented in the solid fermentation chamber. The liquid enters the liquid fermentation chamber through the V-shaped partition and the gas and liquid pipes for liquid fermentation. The fermented solid and liquid bio-organic fertilizers are discharged from the solid discharge port and the liquid discharge valve respectively to obtain solid and liquid bio-organic fertilizers. fertilizer, and effectively prevent the generation of harmful substances. The treatment pool has a simple structure, a small footprint, no energy consumption, and no environmental pollution, and is suitable for widespread popularization and application in towns and villages.

Description

technical field [0001] The invention relates to a garbage treatment device, in particular to a solid-liquid separation fermentation treatment tank for township garbage. Background technique [0002] With the continuous development of the economy, the amount of domestic waste generated in the vast rural areas of our country has also doubled every year. Traditional waste disposal methods are incineration or landfill. However, there are many defects in landfilling: first, landfills occupy a large amount of land, which is a non-renewable resource, and land resources are relatively tight; second, it pollutes the environment; due to the large amount of organic matter and batteries After entering the landfill, the toxic leachate produced will seriously pollute the soil and groundwater. From the perspective of environmental protection, it is necessary to establish an anti-seepage, collection and treatment system for the leachate of the landfill, which will improve the technology. ...

Problems solved by technology

However, there are many defects in landfilling: first, landfills occupy a large amount of land, which is a non-renewable resource, and land resources are relatively tight; second, it pollutes the environment; due to the large amount of organic matter and batteries After entering the landfill, the toxic leachate produced will seriously pollute the soil and groundwater. From the perspective of environmental protection, it is necessary to establish an anti-seepage, collection and treatment system for the leachate of the landfill, which will improve the technology. Difficulty, but also increased investment, complex landfill operation, difficult management, in addition, methane, hydrogen sulfide and other waste in the landfill must also be disposed of to ensure that explosion-proof and environmental protection requirements are met; 3. Waste of resources, a large amount of garbage piled in In the landfill, some materials and energy cannot be used, which causes a certain degree of waste of resources

During the use of traditional garbage incinerators, garbage is put on the grate in the incinerator for incineration. However, when the garbage on the grate is burning, the newly put in garbage instantly covers the burning garbage. It is easy to extinguish the flame, resulting in unstable temperature in the furnace, insufficient garbage incineration, and insufficient garbage incineration will easily produce harmful gases

At the same time, the composition of the garbage is complex, and various combustibles have different properties, which makes the phenomenon of clinker, slag, sintering and other phenomena during the incineration process of the garbage, and the combustion rate is low.

The combustible gas in the flue gas and the combustible matter in the fly ash cannot be completely incinerated, and there are many harmful components in the finally discharged flue gas, which pollutes the environment
