Description

Deodorization equipment for treating odor of low-carbon enzymolysis micro-aerobic compost

Technical Field

The utility model relates to an exhaust-gas treatment environmental protection field especially relates to a deodorization equipment for handling low carbon enzymolysis micro-oxygen compost foul smell.

Background

The fermented compost is used for producing organic fertilizer by composting livestock and poultry excrement and crop straws, and is a good resource utilization method, but the production of the organic fertilizer is often accompanied by the generation of a large amount of odor such as ammonia gas, hydrogen sulfide gas, sulfur dioxide gas, methyl mercaptan gas and the like, and the environment and people can be damaged to different degrees on human respiration, digestion, cardiovascular, endocrine and nervous systems.

The biggest problem in composting is the volatilization and dissipation of ammonia gas, particularly for the composting of livestock and poultry excrement wastes with high nitrogen content, the ammonia gas is a main component of stink in the composting process, and the dissipation of the ammonia gas can pollute the air and influence the human health.

The odor of the fermented compost at the present stage can be treated by a physical deodorization method, a chemical deodorization method and a biological deodorization method.

The physical deodorization method mainly comprises a water washing method, an adsorption method, a masking agent method and a high-altitude diffusion method; the process has the disadvantages that the filtering filler fails after a certain time and needs to be replaced periodically, except for the cost of replacing the filler, the odor can only be discharged into the atmosphere during the replacement, and the process is generally used under the working conditions of small air quantity of the odor and low concentration of the odor.

The chemical deodorization method mainly comprises a direct combustion method, a chemical oxidation method, a neutralization method and a high-temperature oxidation method; because of high investment, complex system and heat source requirement, the method is generally used in occasions with high odor concentration. The boiler and the flue have high requirements on materials and extremely high investment cost, and the tail gas after combustion can cause secondary pollution to the environment.

The biological deodorization method is to degrade the odor in the air by a biological film attached to a filler, and the process of the biological film growing, maturing and achieving the biodegradability is a biological culture process. The microorganism is used for degrading malodorous substances such as ammonia, hydrogen sulfide, mercaptan, thioether and the like into stable oxidation products, thereby achieving the purposes of no odor and harmlessness. The method can dissolve and absorb the malodorous pollutants, and simultaneously can be combined with the degradation action of the microorganism for treatment, and the degraded malodorous substances such as hydrogen sulfide and the like are firstly dissolved in water and then transferred into the microorganism body to be degraded through the metabolic activity of the microorganism. The simple biological deodorization does not need to use medicaments; the odor decomposition by the microorganisms does not need too much external energy; the organism is propagated and excreted to maintain the survival and the vitality of the organism. Factors that affect a biological deodorization system include reactor structure, packing materials, bacterial species, operating parameters, and the like.

At the present stage, the biological deodorization equipment has large investment, is easy to decay, has poor mechanical property, is easy to cause the problems of the collapse, compaction and the like of a packing layer after being used for a long time, and the inert inorganic packing easily causes the problems of low biological activity, long starting time of a reactor, high operation cost and the like.

In conclusion, the deodorizing device for the fermented compost has poor deodorizing effect practicability, cannot meet the requirements of the existing organic fertilizer production, and cannot adapt to the requirements of social development on the environment. The malodor generated in the process of low-carbon enzymolysis and micro-aerobic composting causes great environmental pollution and becomes a bottleneck in the composting process.
