چکیده مقاله:
The smell of sewage treatment plants in cities is one of the social problems that technology has been trying to solve for years. The control and management systems of this type of infrastructure have been concerned with minimizing the environmental and odoriferous impact of this waste, which directly affects the quality of life, especially for those who live near the treatment plants
In most wastewater treatment plants, ammonia and hydrogen sulfide have the highest concentrations and amounts of odor compounds in the emitted gases. Ammonia is a colorless, corrosive gas with a very pungent and unpleasant odor. Its corrosive and exothermic properties can damage the eyes, skin, and mucous membranes of the mouth and respiratory tract.
Another very nuisance odor compound, emitted by wastewater treatment plants, is hydrogen sulfide a colorless, highly flammable and explosive gas, with the smell of rotten eggs, felt in very low concentrations. This gas has a toxic effect on all living organisms,
including humans, causing a number of unpleasant life-threatening ailments.
