Problems solved by technology

The incineration method has a large investment, a long period of capital occupation, a large amount of fuel is required for combustion, high operating costs, a large amount of soot produced by combustion, complex components, difficult flue gas treatment, and easy pollution of the atmosphere; it is difficult to treat organic waste with low calorific value
For this reason, the applicant invented an organic waste treatment device with the patent number of 03248754.1. The organic waste treatment device can decompose the organic matter in the organic waste through fermentation to produce non-toxic and harmless substances, achieving pollution-free The purpose of garbage disposal; however, the device can only deal with kitchen biodegradable organic garbage such as food waste, fruit and vegetable waste, meat and meat bones, and cannot do anything about combustible garbage

Embodiment Construction

[0037] A kind of municipal refuse disposal method that this embodiment mode introduces, its technological process is as follows:

[0038] 1. Sorting garbage according to biodegradable garbage and combustible garbage;

[0039] 2. Ferment and degrade the biodegradable garbage into the biogas fermentation tank to generate biogas;

[0040] The process of entering the tank for fermentation is as follows:

[0041] (1) Crush biodegradable garbage and put it into the acid pool for retting,

[0042] (2), stack retting 1-2 days, when temperature reaches 40 ℃, add water 6-8% by weight percentage, acidify 1-2 days,

[0043] (3), before entering the biogas fermentation tank, adjust the pH value of the mash to 6.8-7.5,

[0044] (4), maintain the pH value of the fermented liquid in the biogas fermentation tank to be 6.8-7.5, and the temperature is 55-60°C;

[0045] 3. Lead the biogas produced in the biogas fermentation tank into the incinerator to burn combustible garbage.

[0046] 4. I...

Abstract

A method for treating city garbage includes such steps as classifying the garbage into the garbage A able to be biologically decomposed and the combustible garbage B, loading the garbage A in marsh gas pool to generate marsh gas, using the marsh gas to burn the garbage B in incinerator and installing the duster in the chimney of incinerator to remove the dust from fume.

Description

Technical field [0001] The invention relates to a method for treating urban garbage. Background technique [0002] At present, garbage disposal methods include landfill and incineration. The landfill method requires a special site, requires a large investment, and is likely to cause secondary pollution to the environment. The incineration method is a high-temperature heat treatment technology, that is, a certain amount of excess air and the organic waste to be treated are oxidized and burned in the incinerator, and the harmful substances in the waste are oxidized and pyrolyzed at a high temperature of 800-1200 ° C. destroy. The incineration method has a large investment, a long period of capital occupation, a large amount of fuel is required for combustion, high operating costs, a large amount of soot produced by combustion, complex components, difficult flue gas treatment, and easy pollution of the atmosphere; it is difficult to treat organic waste with low calorific valu...
