Composting treatment system with automatic deodorization capacity

Abstract

The invention relates to a composting treatment system with an automatic deodorization capacity. The system comprises an outer film, an inner film, a gas-rib type framework and two deodorization bases, wherein the outer film and the inner film are propped open by the gas-rib type framework; two ends of the outer film and two ends of the inner film are fixed on the two deodorization bases respectively, so that a sealed space is formed between the outer film and the inner film; a heap is placed in the inner side of the inner film, odorous gas and water vapor produced by the heap enter the sealed space formed by the outer film and the inner film through the inner film, the water vapor is condensed into water in the sealed space, odorous gas molecules can be absorbed and dissolved in condensate water, and waste water is formed, slips into the deodorization bases at the bottom along the inner side of the outer film and the outer side of the inner film and is discharged through the deodorization bases. Compared with the prior art, the system is simple in structure, detachable and capable of isolating and removing putrid odor and water vapor produced through composting treatment of biomass waste.

Description

technical field [0001] The invention relates to a self-deodorizing composting treatment system, which belongs to the fields of environmental protection and resource comprehensive utilization. Background technique [0002] Composting is a biological treatment technology that is widely used in the treatment of kitchen waste, domestic waste, sludge, manure, straw and other biomass waste. It refers to the use of aerobic microbial metabolism to stabilize the degradation of biomass waste and make it no longer perishable. Smelling, the process of becoming a soil conditioner compatible with plant growth. Moisture control and odor control are two key technologies of composting. [0003] The pores of the pile material must maintain a certain gap to ensure smooth air flow, maintain an aerobic state, and avoid the formation of anaerobic areas. Therefore, biomass waste with high moisture content often needs to add conditioners to reduce the moisture content of the feed, and at the same...

Problems solved by technology

[0008] The above methods all use a layer of covering material (including multiple layers of material), and the synchronous control effect of moisture and odor is not ideal: the amount of water vapor emitted during forced ventilation is large, but the amount of odor emitted is also large; High air permeability, that is, when the ventilation effect is good, it means that the pore size is large, and it is easy to pass through malodorous gas molecules, even bacteria and aerosols at this time; bacteria, aerosols, and condensate will gradually form after the inside of the covering material blocks bacteria, aerosols, and condensate Although biofilm or scaling layer is beneficial to further remove odorous gas molecules, the pore size of the covering material will gradually shrink, resulting in reduced air permeability and water vapor cannot be discharged; the covering directly above the pile is easily contaminated and grow bacteria
