The correct term for a "wastewater treatment plant" is actually a "materials recovery factory".

Any oxidizing agent tend to get reduced [ O + H2 - H2O] & any reducing agent tend to get oxidized [ H2 + 0 - H20] . Sulphide gas being a reducing agent, caused by anaerobic bacteria, any Peroxy compound can neutralize suphide gas. Sensing of chemical nature [ oxidizing/ reducing/ halogen etc ] could be a potential closed loop checking means to decide the chemical nature of the odour.

Sometimes the cheese factory just pumps wastewater into a stagnant holding pond, and expects the locals to deal with the stench. Not justice.
