Organic garbage reduction treatment device and organic garbage reduction treatment method

Abstract

The invention relates to an organic garbage reduction treatment device, belonging to the technical field of environmental protection, and aiming at solving the problems that in the prior art, an organic garbage treatment technology is complicated and high in cost. The organic garbage reduction treatment device comprises a feeding system, a pretreatment system and a reduction treatment system which are sequentially connected, wherein the reduction treatment system comprises a stock bin, a heating device arranged at the outer side of the stock bin, a stirring device, a waste gas treatment device arranged on the top of the stock bin, and a waste water treatment device and a discharge hole which are respectively arranged at and formed in the bottom of the stock bin; the reduction treatment system also comprises an automatic dosing unit and an oxygen replenishment device which are arranged at the outer side of the stock bin. According to the organic garbage reduction treatment device, solid organic garbage is treated by crushing, carrying out solid-liquid separation and sterilizing at high temperature; after that, strains are added into the treated organic garbage, and the organic garbage is filled with oxygen so as to be fermented, so that the organic garbage is converted into an organic fertilizer; therefore, the reduction, recycling and harmless treatment of the organic garbage are realized.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a garbage treatment device, in particular to an organic garbage reduction treatment equipment. Background technique [0002] Urban waste disposal has become a major research topic in the field of environmental protection in the world today. With the rapid development of cities around the world, the amount of urban waste is increasing rapidly around the world. The harmful components in it cause serious harm to the atmosphere, water, soil, etc., affect the urban ecological environment, and endanger the health of the people. It has become a world public hazard. Most cities in our country are already surrounded by garbage, and the treatment of garbage and sewage has become a problem of concern to the world. [0003] Organic waste accounts for more than 50% of urban domestic waste (such as kitchen waste, vegetable collection waste, etc.), and organic waste contains a l...

Problems solved by technology

[0003] Organic waste accounts for more than 50% of urban domestic waste (such as kitchen waste, vegetable collection waste, etc.), and organic waste contains a lot of water (the highest water content of kitchen waste is about 85%). Reduction, recycling, harmless

For example, using the incineration method to treat kitchen waste not only reduces the temperature of the incinerator, damages the furnace body, and reduces its service life, but also easily produces toxic dust particles such as dioxin during the incineration process, resulting in secondary pollution; the composting method is difficult to treat organic waste. , the composting process is uncontrollable, the garbage is easily corrupted, the resource utilization rate is low, and it is difficult to obtain the required fertilizer; the landfill method can be used to dispose of organic waste, which can be decomposed under the action of microorganisms to achieve the reduction of waste, but During the landfill process, the garbage will rot and smell, breeding mosquitoes and other vectors, affecting the surrounding environment and polluting air and water sources

[0004] Nowadays, the more mature organic waste treatment schemes are nothing more than the use of anaerobic fermentation and ecological biological chain method, but the process operation is difficult, the operation cycle is long, and the operation process has serious pollution to the surrounding environment, so it is difficult to reduce waste conveniently and quickly.
