Embodiment 1

[0031] Municipal solid waste is transported in by a transport vehicle, and the transport vehicle unloads the waste on the drum sorter 1 . When the drum sorter 1 is working, the rotating speed is 8r / min, and the waste materials can be sorted into fermentable organic matter and non-fermentable inorganic matter. The barrel of the drum-shaped sorting machine 1 is squirrel-cage-shaped welded by steel bars 2. It is a three-stage sorting machine, and the gap between the steel bars 2 increases step by step. The gap between the steel bars 2 of the first-stage sorting machine is 6cm, and the blade 3 is set inside, which can effectively disassemble the garbage packaging bags during the sorting process, and sort out non-fermentable dusty garbage, waste batteries, and small pieces of waste. Glass and paper; the gap between the steel bars 2 of the second-stage sorting machine is 10cm, which can sort out waste plastics and shoes; the gap between the steel bars 2 of the third-stage sorting ma...

Embodiment 2

[0033] Municipal solid waste is transported in by a transport vehicle, and the transport vehicle unloads the waste on the drum sorter 1 . When the drum sorter 1 is working, the rotating speed is 10r / min, and the waste materials can be sorted into fermentable organic matter and non-fermentable inorganic matter. The barrel of the drum-shaped sorting machine 1 is squirrel-cage-shaped welded by steel bars 2. It is a three-stage sorting machine, and the gap between the steel bars 2 increases step by step. Drum sorting machine 1 steel bar 2 with a gap of 5cm, internally equipped with blade 3, which can effectively disassemble garbage packaging bags during the sorting process, and sort out non-fermentable dusty garbage, waste batteries, and small pieces of waste glass and paper; the second-stage steel bar 2 gap of the drum sorter 1 is 8cm, which can sort waste plastics and shoes; the third-stage steel bar 2 gap of the drum sorter 1 is 18cm, which can sort out Large pieces of waste g...

Embodiment 3

[0035]Municipal solid waste is transported in by a transport vehicle, and the transport vehicle unloads the waste on the drum sorter 1 . When the drum sorter 1 works, the rotating speed is 12r / min, and the waste materials can be sorted into fermentable organic matter and non-fermentable inorganic matter. The barrel of the drum-shaped sorting machine 1 is squirrel-cage-shaped welded by steel bars 2. It is a three-stage sorting machine, and the gap between the steel bars 2 increases step by step. The gap between the steel bars 2 of the first stage of the drum sorter 1 is 8cm, and the blade 3 is set inside, which can effectively disassemble the garbage packaging bags during the sorting process, and sort out non-fermentable dust garbage, waste batteries, Small pieces of waste glass and paper; the gap between the steel bars 2 of the second stage of the drum sorter 1 is 10cm, which can sort waste plastics and shoes; the gap between the 2 steel bars of the third pole of the drum sort...

Abstract

The invention provides an urban living garbage treatment method which comprises a separating working procedure, a smashing working procedure, a solid fermentation working procedure, a washing and cleaning working procedure, a methane fermentation working procedure and a fertilizer making working procedure, so that natural gas and an organic fertilizer product can be obtained. In a sorting step, a three-stage rotary type sorting machine is adopted, so that fermentable organic substances and non-fermentable inorganic substances can be efficiently and rationally sorted. During methane fermentation, a heatable heat preservation fermentation tank is adopted, so that the methane fermentation efficiency and the methane fermentation quality are improved. By the urban living garbage treatment method, a complete treatment and recycling effect is achieved; and the urban living garbage treatment method is high in efficiency, environment-friendly and high in social and production benefits.

Description

technical field [0001] The invention relates to the field of waste treatment, in particular to a method for treating municipal domestic garbage. Background technique [0002] With the acceleration of urbanization in our country, the scale of cities is getting bigger and bigger; with the continuous development of the national economy, the continuous improvement of people's living standards and the change of people's consumption habits, the amount of urban and rural domestic waste continues to increase. These increasing urban and rural domestic wastes have seriously troubled the further development of cities and seriously affected people's lives. [0003] At present, there are several ways to deal with urban and rural domestic waste in China, such as incineration for power generation, classification and recycling, or landfill. Among them, landfill is still the main treatment method. Building a landfill not only takes up valuable land resources, but also consumes a lot of man...
