Abstract The production and emission of hydrogen sulfide in sewer systems is associated with several problems, including malodor, toxicity on sewer workers and biogenic corrosion of concrete pipe. Oxygen aeration is a more adopted method of controlling hydrogen sulfide production and accumulation. The paper aims to study on the influence of different oxygen aeration condition on sulfide accumulation, carbon source consumption process of sewer system by lab-scale batch experiments. Result indicated that the liquid sulfide concentration can be controlled by oxygen aeration which oxidizes the sulfide generated of sewer system. The sulfide accumulation, carbon source consumption is significantly affected by aeration frequency. The way of more short intermittent oxygen aeration can effectively suppress sulfate reduction, prevent the accumulation of liquid phase sulfide and consume less organic carbon source in the sewer system.
