Garbage treatment method

Abstract

The invention relates to a garbage treatment method. In the method, a garbage treatment device is adopted. The garbage treatment device comprises a quantitative feeding device, a bag breaking device,a roller screen device, a conveying device, a drying device, a crushing device and a squeezing and dehydrating device. The garbage treatment method comprises the steps of garbage bagging, bag breaking, roller screening, manual sorting, metal removal, conveying, drying, deodorizing, secondary manual sorting, crushing treatment and squeezing and dehydrating treatment. According to the garbage treatment method, urban and rural household garbage is subjected to roller screening, sorting, metal removal, drying, secondary sorting, crushing and squeezing and dehydrating treatment, and then garbage powder for being made into an organic fertilizer raw material can be obtained. On one hand, metal garbage, harmful garbage and recoverable garbage are sorted out from mixed household garbage in the process of treating the urban and rural household garbage; on the other hand, the remaining household garbage subjected to sorting is treated into substances which can be made into the organic fertilizerraw material. The organic fertilizer raw material is used for soil irrigation. There is no need to conduct landfill in a large-area land. Harmful substances cannot be generated, and environmental pollution is avoided. The utilization rate of garbage is increased.

Description

technical field [0001] The invention relates to the technical field of garbage recovery and treatment, in particular to a garbage treatment method. Background technique [0002] Urban and rural domestic waste generally refers to the waste generated by urban and rural military and civilian life. At present, domestic domestic waste is not distributed and collected. Therefore, the garbage collected is mixed together with various types of waste; 165 million tons, the backlog of waste has reached more than 7 billion tons. With the increase of urban and rural population in the future, the annual waste production is expected to grow at a rate of 8%. According to statistics, the vast majority of domestic waste is untreated and piled up in the suburbs, occupying an area of ​​500 million square meters of land. The disposal of pajamas destroys urban and rural landscapes, and at the same time breeds germs and pollutes the environment. [0003] In the existing urban and rural domestic w...

According to statistics, the vast majority of domestic waste is untreated and piled up in the suburbs, occupying an area of ​​500 million square meters of land. The disposal of pajamas destroys urban and rural landscapes, and at the same time breeds germs and pollutes the environment.

[0003] In the existing urban and rural domestic waste treatment methods, the common treatment method is to landfill or pile up the waste and then burn it. Among them, landfill needs to occupy land, and may also cause surface pollution and groundwater pollution. At the same time, landfill may also The generation of methane pollutes the atmosphere; and the incineration of garbage will produce harmful gases such as dioxins, which will damage human health and cause great damage to animals and plants
