Composting Machine as an Instrument for Environmental Protection through Gas Reduction
date: 2024-12-28

As a core equipment in the waste treatment process, the composting machine can convert organic solid waste from different sources into stable compounds. It is an effective treatment technology for solid waste resource utilization, reduction and harmlessness, and is widely used in the treatment of livestock and poultry manure. However, the gas produced during the fermentation process of the composting machine with automatic features is also a problem that everyone has been concerned about. This article will focus on the environmental protection effect of the composting machine in gas reduction and control during the fermentation process.

 

1. Composting machine gas emissions

 

The malodorous gas produced by the composting machine with automatic features during the fermentation process is the result of the interaction of indigenous microorganisms during the manure fermentation process. These microorganisms decompose livestock and poultry manure, which includes a series of biochemical processes. Among them, protein and amino acid decarboxylation and deamination are important ways to produce malodorous substances, which are easy to produce NH3, H2S and other malodorous gases. During the biodegradation process of manure composting, intermediate products are formed, producing a large amount of malodorous substances such as NH3, VSCs, VOCs, etc. This type of odorous substance is highly irritating and toxic. The differences in the amount of livestock and poultry urine mixed, moisture, temperature, ventilation, pH and stacking time will have a great impact on the composition and quantity of malodorous substances.

 

 

2. Composting machine odor treatment technology

 

①Physical method

 

Physical deodorization methods mainly include masking method, dilution method, condensation method, absorption method and adsorption method. The principle of physical deodorization method is to eliminate odor by transforming solid, liquid and gas.

 

②Chemical method

 

Chemical deodorization methods mainly include acid-base absorption method, chemical adsorption method, chemical washing method, oxidation method, photocatalytic oxidation method, etc. The common point of these methods is to change the chemical structure of odor components, destroy their odor-causing groups, and transform them into odorless or low-odor substances, thereby playing a deodorizing role.

 

③Biological method

 

The gas component first contacts with water and dissolves in water, further diffuses to the biofilm, and is then captured and absorbed by the microorganisms therein; the odor components entering the microorganisms are decomposed as energy and nutrients in their own metabolic process. In recent years, various deodorization technologies have emerged in an endless stream, and biological deodorization technology has become the mainstream technology for livestock and poultry manure treatment due to its environmentally friendly characteristics. It is suitable for controlling the odorous gases generated in complex composting machines with low energy consumption. The biochemical reaction is eventually converted into harmless compounds.

 

 

3. Bolong composting machine deodorization technology innovation

 

Bolong Deodorization System 5.0 uses activated carbon adsorption combined with microbial decomposition technology and water spraying technology to cleverly treat waste gas comprehensively. The odor to be treated is sent to the spray tower through the air inlet pipe, and the water containing a large number of microorganisms in the water storage tank enters the spray tower through the water inlet pipe to form a water curtain. Some sulfides, ammonia nitrogen and other components in the waste gas are absorbed or dissolved by the liquid film on the surface of the biofilm in the water curtain, and are eventually degraded into CO2, H2O, inorganic salts and other substances. After preliminary treatment, the waste gas will enter the activated carbon adsorption layer, and the waste gas will flow through the activated carbon layer from bottom to top. The small amount of sulfides, ammonia nitrogen and other components remaining in the waste gas will eventually be captured by the activated carbon. The deodorization effect of the whole system is significant, and the later operation and maintenance is relatively simple. It is unanimously recognized by composting machine customers at home and abroad.

 

4. The importance of composting machines in the field of environmental protection

 

The composting machine is the core equipment in the waste treatment process. The closed design of the tank body reduces the leakage of most polluting gases.

In addition, most composting machines with low energy consumption are equipped with corresponding deodorization technology, and their gas pollution to the environment is relatively small compared to traditional composting. As an advanced environmental protection equipment, the composting machine plays an important role in the field of environmental protection by efficiently treating organic waste and reducing gas emissions.

 

 

In short, in terms of odor treatment, the composting machine for organic farming combines the diversified solutions of modern technology to meet the needs of different application scenarios. The innovative technology represented by the Bolong composting machine for organic farming has set a benchmark for the industry. In the future, with the continuous advancement of technology, the composting machine for organic farming is expected to make greater contributions in reducing greenhouse gas emissions, improving air quality, and realizing resource recycling.
