Landfill solidified fly ash landfill operation dust prevention and dustfall system and implementation scheme

Abstract

The invention discloses a landfill solidified fly ash landfill operation dust prevention and dustfall system. The system comprises a temporary operation road, a discharging platform, a watering cart and fog bubbles which are correspondingly arranged along an annular field road according to an elevation of a solidified fly ash landfill pile body. The temporary operation road and the discharging platform comprise a roadbed steel plate box, an HDPE film cover, a granular solidified fly ash pile body and geotextile, and the HDPE film cover forms a sealing film cover in a welded mode.

Description

technical field [0001] The invention relates to the technical field of solidified waste treatment, in particular to a dust-proof and dust-reducing system for solidified fly ash landfilling in a landfill and an implementation plan. Background technique [0002] In the trial landfill operation process of the fly ash landfill reservoir area in the prior art, a dumping and unloading platform is set up in the separation dam, and the pile height method is used to dump and unload from the bottom of the reservoir along the elevation from the bottom to the height. With the further expansion of the height and depth of the landfill, the landfill solidified fly ash is directly used to build a temporary road for landfill operations, and the wheels of the solidified fly ash transport vehicles are in direct contact with the solidified fly ash pile, and continue along the landfilled pile. Extending to high places, the working area is constantly expanding, and the dust is further intensified...

Problems solved by technology

[0002] In the trial landfill operation process of the fly ash landfill reservoir area in the prior art, a dumping and unloading platform is set up in the separation dam, and the pile height method is used to dump and unload from the bottom of the reservoir along the elevation from the bottom to the height. With the further expansion of the height and depth of the landfill, the landfill solidified fly ash is directly used to build a temporary road for landfill operations, and the wheels of the solidified fly ash transport vehicles are in direct contact with the solidified fly ash pile, and continue along the landfilled pile. Extending to high places, the working surface continues to expand, and the dust is further intensified when the transport vehicles enter and leave the site and unload. The method used to solve the dust problem in the prior art is to use water spraying to reduce dust simply and extensively, and the effect is poor.
