Landfill oversize product combustion treatment method for promoting up-to-standard emission of pollutants

Abstract

The invention discloses a landfill oversize product combustion treatment method for promoting up-to-standard emission of pollutants, and belongs to the technical field of up-to-standard emission of pollutants. The landfill oversize product combustion treatment method comprises the following steps: S1, dividing a refuse landfill into areas with the size being 1000-10000 square meters to remove refuse piece by piece; and S2, preliminarily breaking bags by using a rotary excavator provided with a digging shovel and a bag breaking knife while the refuse is dug out, and conveying the refuse to a loading and unloading vehicle to be conveyed to a belt conveyor. According to the refuse carbonization combustion treatment process, the blending combustion amount each time does not exceed 30% of the total amount of the incinerated refuse, ascending hot air flow generated by refuse combustion is utilized for drying and carbonizing the refuse, so that the refuse combustion characteristic is improved, and the refuse is combusted more fully; and by additionally arranging a flue gas secondary combustion procedure, combustible gas which is not fully combusted in flue gas is further combusted, the content of the pollutants in the flue gas is greatly reduced, and the original refuse landfill can be cleaned and reused.

Description

technical field [0001] The invention relates to the technical field of up-to-standard discharge of pollutants, in particular to a burning treatment method for landfill sieves that promotes up-to-standard discharge of pollutants. Background technique [0002] The leachate treatment system in the construction of the domestic waste landfill is the key to the success of the landfill technology, which is directly related to the pollution degree of the nearby surface water. There are two ways to bury the waste: dumping - digging an open air on the ground The pits where the rubbish is buried are surrounded by various animals (rats and birds). Landfill - Constructing an elaborate facility underground or above ground to isolate waste from its surroundings (groundwater, air, and stormwater). This isolation is achieved with a bottom liner and soil covering that is done daily. Sanitary landfills – separate waste from the environment with a clay liner Municipal solid waste landfills – ...

AI Technical Summary

Problems solved by technology

The pollutants produced in the process of domestic waste incineration mainly include four categories: particulate matter, acid gas, heavy metals and organic pollutants. The tail gas emitted by waste incineration has a certain impact on the surrounding environment and is not good for the human body. For this reason, we Propose a burning treatment method for landfill sieves that can promote the discharge of pollutants up to the standard
