Why does the newly renovated sewage treatment plant still have a foul smell?

There are many sources of unpleasant odors in wastewater treatment; in conventional biochemical processes, these odors mainly arise from anaerobic reactions. Some special wastewater treatment methods also produce strong odors. It is recommended to inspect each unit involved, collect the odorous gases and release them at high altitudes to reduce odors within the plant, or install an odor treatment system to eliminate them.
