During the processing of down feathers, a certain amount of wastewater is generated, often accompanied by noticeable odors. These odors primarily stem from residual oils, protein decomposition products, and other organic matter during the washing of down. These substances easily decompose and produce foul smells under anaerobic conditions, especially with the release of gases such as hydrogen sulfide (H₂S) and ammonia (NH₃), leading to strong odors at the wastewater treatment site.
To address this issue, it is recommended to use specialized plant-based deodorizing agents. Beijing Deodorizing Agent is a highly concentrated, eco-friendly solution developed specifically for the pharmaceutical industry to effectively remove unpleasant odors. The main ingredients of plant-based deodorizing agents include over 50 plant extracts such as mint, citronella, tea polyphenols, grape seed, camphor tree, yucca, eucalyptus oil, wormwood, pine oil, among others. The active molecules contain conjugated double bonds and other reactive groups, making them highly effective in neutralizing various odors, foul smells, and common industrial exhaust gases. These agents can quickly neutralize and decompose odor-causing organic substances, converting them into carbon dioxide and water, while being non-toxic and harmless to humans.
Key Methods of Application:
-
Space Spraying for Odor Removal: The deodorizing agent is diluted 200 times and sprayed as a mist using a sprayer. The mist droplets disperse in the designated area, where they adsorb odor molecules in the air. These odor molecules undergo changes in their molecular structure, becoming unstable. Simultaneously, the odor molecules on the surface of the droplets can react with oxygen in the air. As a result, the odor molecules are converted into odorless and harmless compounds such as water and inorganic salts, effectively eliminating odors. This method is effective in breaking down hydrogen sulfide, ammonia, and other volatile organic compounds (VOCs) present in industrial odors and exhaust gases.
-
Direct Odor Control in Wastewater: The deodorizing agent can be directly added to the wastewater to neutralize odors. By adding 0.1-1 kg of deodorizer per ton of wastewater, the production of foul odors can be controlled at the source.
Effectiveness:
Plant-based deodorizing agents, particularly those like Beijing Deodorizing Agent, have proven to be highly effective in the down processing industry. They not only neutralize and decompose odors quickly but also ensure that the resulting by-products (CO₂ and H₂O) are safe and environmentally friendly. The method is suitable for both space spraying and direct application in wastewater, providing a comprehensive solution to controlling and eliminating odors in down processing facilities.
