Problems solved by technology

[0017] However, both soil cover and recycled aggregate cover have several serious drawbacks: (1) These covers are not capable of absorbing or treating H 2 The purpose of S is only to provide a barrier to isolate and prevent overflow; (2) due to the fact that H 2 S is not absorbed or processed, H 2 S will accumulate under the low-permeability layer, and the air pressure will increase with time, and eventually break through the intake pressure value of the low-permeability layer, forming a through channel, and then lose the air-holding function

Embodiment Construction

[0069] The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. It is necessary to point out that the schematic embodiments and descriptions of the present invention are only used to further explain the present invention, and cannot be interpreted as limiting the protection scope of the present invention. Those skilled in the art can make some non-essential improvements and adjustments based on the content of the present invention above.

[0070] like Figure 1-Figure 7 Shown is a kind of odor adsorption material for landfill. The raw material is recycled fine material. The recycled fine material is made by mixing recycled fine aggregate and recycled powder prepared by recycling construction waste, and the recycled fine aggregate and recycled powder are prepared. Concrete and mortar account for more than 95% of the construction waste, and the particle size distribution curve of the odor adsorptio...

Abstract

The invention provides an odor adsorption material for a refuse landfill, an adsorption system and a preparation method. H2S in the refuse landfill can be efficiently absorbed. The odor adsorption material for the refuse landfill is characterized in that a raw material is a regenerated fine material formed by blending regenerated fine aggregate prepared by recycling construction waste and regenerated powder, and the recycled construction waste contains quick lime or slaked lime. The invention relates to an odor adsorption system for a refuse landfill. The system comprises at least one middle adsorption subsystem and an uppermost closure adsorption subsystem, the middle adsorption subsystem comprises three functional layers, namely an upper gas collection layer, an odor adsorption layer II and a lower gas collection layer in sequence from top to bottom; the closure adsorption subsystem comprises six functional layers, namely a vegetation layer, a drainage layer, an impermeable layer, a guide and discharge layer, an odor adsorption layer I and a gas collection layer I from top to bottom in sequence, and the odor adsorption layer I and the odor adsorption layer II are made of odor adsorption materials.

Description

technical field [0001] The invention relates to the field of garbage landfill technology, in particular to an odor adsorption material, an adsorption system and a preparation method for a garbage landfill. Background technique [0002] In recent years, with the sustained and rapid development of my country's national economy and the acceleration of urbanization, urban waste has increased dramatically. As of 2012, China's municipal solid waste removal volume is about 171 million tons, except for a small amount of disposal by incineration, composting and recycling, more than 60% are disposed of by sanitary landfill. Domestic waste contains a large amount of organic matter, and a large amount of odorous substances will be released during the landfill process. Among various malodorous substances, especially hydrogen sulfide (H 2 S) is the most typical and common. [0003] H in landfill 2 S odor mainly comes from the oxidation of sulfur-containing organic matter and the reduc...
