Method for producing organic compost fertilizer

Abstract

The present invention relates to a method for producing an organic compost fertilizer. More specifically, in order to reduce the odor generated from various compost facilities, compost raw ingredients, such as livestock excrement, food waste, animal and plant waste residues, sewage sludge, or the like, having a pungent odor may be treated with ozone (O3) to produce a compost raw ingredient with reduced odor, and while supplying oxygen thereto, an organic compost fertilizer may be produced through a decomposing and fermenting step using aerobic microbes and odor may be reduced. Compost at a post-decomposition facility that has been completely decomposed through the decomposing and fermenting step and moved to a post-decomposition facility may be packed and shipped as an organic compost fertilizer product after going through a post-decomposition process in which organic material that is without odor but remains in the compost in an undigested state and non-biodegradable material such asfiber is stored and decomposed for 2 to 6 months, so as to store and age same thereby making compost. Since the organic compost fertilizer product is discharged after the concentration of the odor thereof is reduced by a factor of 2000 to 400 through an air dilution olfactory method, unpleasant odors are reduced by 50 to 80% compared to the initial state, and thus can increase the popularity thereof to consumers.

Description

technical field [0001] The present invention relates to a kind of production method of organic composting fertilizer, in order to reduce the smell that various composting yards produce, the composting raw material such as animal feces, food waste, animal and plant waste residues, sewage sludge that give out very big smell is subjected to ozone (O 3 ) treatment to produce compost raw materials with reduced odor, not only can organic compost manure be produced by decomposing (fermentation and maturation) process using aerobic microorganisms while supplying oxygen to compost raw materials, but also can reduce odor, through decomposing fermentation Although the post-ripening field compost that has been fully matured and moved to the post-ripening (post-ripening) field has no smell, it can be packaged as an organic compost fertilizer product and shipped after the post-ripening process. The post-ripening process is to make the compost inside Refractory substances such as organic mat...

Problems solved by technology

[0011] Although this method of composting organic waste has the advantage of composting organic waste, the disadvantage is that the quality of the compost produced by this method is low, and the manufacturing process cannot be unified. Problems that lead to spoilage of organic waste

[0012] In addition, in the previous situation, in order to reduce the odor, in the composting room, ozone, chlorine dioxide gas, wood vinegar, microbial materials, etc. were sprayed into the composting room to reduce the odor generated during the composting process, or there were In the case of exhausting to the outside, adsorption by wet and dry scrubbers, chemical decomposition, and destruction, etc., but the odor generated from compost raw materials cannot be removed from the source

[0013] However, compost materials such as livestock manure, food waste, animal and plant waste residues, and sewage sludge are corrupted during production and treatment (anaerobic fermentation), which makes the inherent odor of the raw materials and the ammonia produced by anaerobic fermentation Gas, hydrogen sulfide, amines, mercaptans and other complex odors produce high-intensity stench

The fact is that by subjecting these compost materials to ozone (O 3 ) treatment to produce compost raw materials with reduced odor. While supplying oxygen to the compost raw materials, the compost raw materials are matured through the decomposing fermentation process using aerobic microorganisms and then moved to the post-ripening field, so that the remaining organic matter and fiber are not digested. Such refractory materials are stored and decomposed for 2 to 6 months. After being stored and matured to become compost, they are packaged as organic compost fertilizer products and shipped. An organic fertilizer production method that reduces odor in the entire process has not yet been developed.
