A waste disposal system and method

Abstract

The invention discloses a garbage treatment system. The system is a tower structure, and is provided with a warehouse layer, an earthworm cultivating layer, a stack retting layer, a biogas layer, a biogas storage layer, a power generation layer and a lighting layer in sequence from bottom to top; the biogas layer is provided with a biogas pool; the biogas storage layer is provided with a biogas tank; the biogas pool is connected with a biogas conveying pipeline leading to the biogas tank; the power generation layer is provided with a biogas generator; the stack retting layer is provided with a stack retting pool; the earthworm cultivating layer is provided with an earthworm cultivating bed; a product machining layer is arranged between the warehouse layer and the earthworm cultivating layer; an earthworm product machining production line is arranged in the product machining layer; and a solar photovoltaic panel is arranged at the top of the lighting layer. The invention further discloses a method for garbage treatment by using the system. The system changes garbage to wealth when greenly treating the garbage, and uses self-produced biogas to supply electricity and heat to the internal or the external of the system; the produced earthworm products can be used for aquatic product and animal cultivation and crop fertilizer application; and stalks and animal wastes are used for preparing fermentation base stocks to realize recycling.

Description

technical field [0001] The invention relates to a system and a method, in particular to a garbage treatment system and a method for treating garbage. Background technique [0002] The population of the world today is nearly 7 billion, and the domestic waste generated every year is about 3.5 billion tons, and the annual disposal cost of domestic waste is as high as 300 billion U.S. dollars. my country has a population of 1.4 billion, and the annual production of domestic waste is about 600 million tons, plant waste is 600 million tons, and animal waste is 600 million tons. There are about 1 billion tons of feces. At present, people mostly use landfill and incineration to deal with these garbage, which has caused serious damage to the ecological environment of the earth and a huge threat to human health. Therefore, it is an urgent need for human beings to design a system that is both environmentally friendly and can effectively manage garbage. Contents of the invention [00...
