Abstract
Thepresent invention provide one kind of biological filtering method to eliminate off odor from solid waste and aims at avoiding the environmental pollution caused by off odor producing compost with solid waste. The biological filtering process includes three steps: mass transfer to convert partial off odor into liquid phase based on adsorption-biomembrane theory; microbe absorption of the off odor dissolved in water via its cell membrane and cell wall; and the decomposing and utilizing of the off odor entering the cell to eliminate off odor. After the off odor is decomposed, nitrogenous odor is decomposed into NH3, NH3 is oxidized by nitrifying bacteria into stable nitric acid compound by bacteria, sulphurous off odor is decomposed into H2S and H2S is oxidized by sulfur bacteria into sulfuric acid.
Description
Technical field:
The invention belongs to the filtration treatment field of discarded object.
Background technology:
Municipal solid wastes will produce foul smell in the process of compost treatment at present, and the Main Ingredients and Appearance of foul smell is H
2S and NH
3, also have a spot of organic gas such as methyl mercaptan, methylamine, methyl sulphur etc. in addition.These gaseous volatilizations are bigger, easily be diffused in the atmosphere, and portion gas are poisonous, penetrating odor is big.If deal with improperly, compost production is exactly a kind of process of producing stench and forming public hazards, that is to say when disposing rubbish, produces new pollution again.
Technology contents:
For addressing the above problem, the invention provides a kind of biological filtering method of removing the eliminating off odour from solid waste of the foul smell that solid waste produced by the method foul smell of biofiltration.
Technical scheme of the present invention is that the process of utilization biofiltration process removal eliminating off odour from solid waste is divided into three processes: according to absorption---biomembrance process is changed into the part foul smell mass transport process of liquid phase by gas phase; Foul smell soluble in water is absorbed by microorganism by cells of microorganisms wall and cell membrane, and water-fast foul smell is earlier attached to outside the microbial body, is decomposed into solable matter by the ectoenzyme of microorganism secretion, infiltrates cell again; After foul smell enters cell, be that Institute of Micro-biology decomposes, utilizes as nutriment in vivo, foul smell is removed.
Adopt this method foul smell after microorganism is decomposed, nitrogenous foul smell such as amide-type after the ammoniation of microorganism, are decomposed into NH
3, NH
3Through the effect of nitrite bacteria, nitrobacteria, further be oxidized to stable nitric acid attitude compound again; The foul smell of sulfur-bearing produces H after microorganism is decomposed
2S, H
2S is oxidized to sulfuric acid through sulfur bacteria.
The specific embodiment:
The process that the present invention uses biofiltration process to remove eliminating off odour from solid waste is divided into three processes:
According to absorption---biomembrance process is changed into the part foul smell mass transport process of liquid phase by gas phase.
Foul smell soluble in water is absorbed by microorganism by cells of microorganisms wall and cell membrane, and water-fast foul smell is earlier attached to outside the microbial body, is decomposed into solable matter by the ectoenzyme of microorganism secretion, infiltrates cell again.
After foul smell enters cell, be that Institute of Micro-biology decomposes, utilizes as nutriment in vivo, foul smell is removed.
Claims (1)
1, a kind of biological filtering method of eliminating off odour from solid waste is characterized in that: the process that the utilization biofiltration process is removed eliminating off odour from solid waste is divided into three processes:
A, foundation are adsorbed---and biomembrance process is changed into the part foul smell mass transport process of liquid phase by gas phase;
B, foul smell soluble in water are absorbed by microorganism by cells of microorganisms wall and cell membrane, and water-fast foul smell is earlier attached to outside the microbial body, are decomposed into solable matter by the ectoenzyme of microorganism secretion, infiltrate cell again;
After c, foul smell enter cell, be that Institute of Micro-biology decomposes, utilizes as nutriment in vivo, foul smell is removed.
