Composting machines, crucial in waste treatment, convert diverse organic solid waste into stable compounds, promoting waste resource utilization, reduction, and harmlessness, especially in livestock and poultry manure treatment. However, the gas emitted during their fermentation is a major concern.
During the fermentation of livestock and poultry manure in automated composting machines, indigenous microorganisms trigger a series of biochemical reactions. Protein and amino acid decomposition processes like decarboxylation and deamination produce malodorous gases such as NH₃ and H₂S. The biodegradation of manure also generates intermediate products, releasing a large amount of irritating and toxic substances like NH₃, volatile sulfur compounds, and volatile organic compounds Factors like the ratio of livestock and poultry urine, moisture, temperature, ventilation, pH, and stacking time significantly impact the composition and quantity of these malodorous substances.
①Physical Methods: These, including masking, dilution, condensation, absorption, and adsorption, eliminate odor by altering the state of solids, liquids, and gases.
②Chemical Methods: Such as acid – base absorption, chemical adsorption, chemical washing, oxidation, and photocatalytic oxidation, change the chemical structure of odor components, destroying their odor – causing groups to produce odorless or low – odor substances.
③Biological Methods: Gas components dissolve in water, diffuse to the biofilm, and are absorbed and decomposed by microorganisms as energy and nutrients. Due to its environmental – friendliness, biological deodorization has become the mainstream for livestock and poultry manure treatment, especially suitable for controlling odors in complex composting machines with low energy consumption.
Bolong’s Deodorization System 5.0 innovatively combines activated carbon adsorption, microbial decomposition, and water spraying. Waste gas enters the spray tower through the air inlet. Water with microorganisms from the storage tank forms a water curtain through the water inlet. Some sulfides and ammonia nitrogen in the waste gas are absorbed or dissolved by the biofilm – covered water curtain and degraded into harmless substances. The pre – treated gas then passes through the activated carbon layer, where remaining impurities are captured. This system offers significant deodorization and easy maintenance, winning wide acclaim.
With a closed – tank design, composting machines reduce the leakage of polluting gases. Equipped with deodorization technologies, they cause less gas pollution than traditional composting methods. As advanced environmental protection equipment, they play a vital role in treating organic waste and cutting gas emissions.
In conclusion, composting machines, like the innovative Bolong model, offer diverse odor – treatment solutions. As technology advances, they are set to contribute more to reducing greenhouse gas emissions, enhancing air quality, and achieving resource recycling.
