The invention discloses a sewage biological treatment low-carbon operation optimization method which comprises the following steps: S1, constructing a dynamic simulation system: according to an activated sludge method, establishing a carbon emission accounting model in combination with migration and transformation and mass balance of carbon elements in a sewage treatment process; establishing a simulation system of a carbon emission process in the whole biological treatment process according to process characteristics and parameters related to operation; s2, determining parameters: determining main initial parameters of the process dynamic simulation system; and S3, simulation operation: acquiring parameters related to dynamics and carbon element conversion in the biological treatment process, substituting the parameters into the simulation system, and analyzing to obtain emission results of CH4 and CO2. The invention provides a low-carbon operation optimization method for biological sewage treatment, which i
