Abstract：Domestic sewage treatment is a key link in environmental protectionand sustainable utilization of water resources.Microbial technology hasbecomethecoreofsewagebiologicaltreatmentduetoitseconomic，eficient，and environmentallyfriendlyadvantages.This paper takesacertain waterpolltioncontrolprojectasanexample toanalyze the application efectof microbial technology in domesticsewage treatment.Theresults indicate thatcomposite microrganisms can effectively remove Chemical Oxygen Demand （COD） and ammonia nitrogen （NH 3 -N） from domestic sewage. Composite microrganisms haveanadaptation period inlow-temperature environments，andthenbeginto growandreproduce inlarge numbers， showing exponential growth in quantity and strong cold resistance.
