摘　　要：The emission of hydrogen sulfide(H_(2)S)in sewers leads to pipeline corrosion and odor issues.Sulfate-reducing bacteria(SRB)reduce sulfate as the main pathway for H_(2)S production in wastewater.Inhibiting SRB activity through chemical or biological methods is an effective strategy to reduce H_(2)S emissions.Therefore,the objective of this review is to provide a comprehensive summary of research in the reduction of H_(2)S production in sewer systems via inhibition of the metabolic activity of SRB.This study provides an understanding on the complex metabolism of SRB,which is crucial for mitigating H_(2)S generation in sewer systems.This review addresses H_(2)S production in sewer systems and its reduction methods by inhibiting SRB activity using both chemical and biological methods.Currently,the addition of chemicals to sewer systems to control H_(2)S has shown good effectiveness.However,these methods face challenges such as the need for repeated dosing,short effective durations,bacterial resistance,and increased loads on downstream wastewater treatment plants.Biological agents are more environmentally friendly,but research on their application for controlling H_(2)S in sewer systems is limited,and their effectiveness and stability are yet to be determined.This review analyses the potential of chemical and biological methods,discusses current applications and future research directions based on SRB inhibition mechanisms,and provides insights for developing more efficient and ecofriendly strategies for H_(2)S control in sewer systems.
