During the operation of industrial wastewater treatment equipment, unpleasant odors often arise. So, how are these odors formed and how can they be controlled?
1.Odor Sources
Odors mainly originate from the collection, treatment processes, and operational conditions of the system. Anaerobic microorganisms in the sludge and on solid surfaces consume organic matter, sulfur, and nitrogen, releasing foul-smelling gases.
2.Odor Components
Industrial wastewater often contains sufficient organic sulfur compounds and inorganic salts. The main odor-causing components include both organic and inorganic molecules, with hydrogen sulfide (H₂S) and ammonia (NH₃) being the two primary inorganic gases.
3.Formation of Organic Odors
Organic odors are typically the result of microbial activity. As microorganisms break down organic matter, they release a mixture of volatile organic compounds that produce strong unpleasant smells.
4.Environmental and Corrosion Concerns
Odor issues not only affect environmental quality but are also linked to equipment corrosion, such as sewer walls, exposed metal parts, and paint surfaces. Effective odor control helps reduce corrosion, improve air quality, and extend the lifespan of the treatment system.
