The invention relates to a method for degrading malodorous gas by coupling a biotrickling filter with dielectric barrier discharge and is used for mainly solving the problem in the prior art that total hydrocarbon cannot be effectively degraded when malodorous components in malodorous waste gas are effectively removed. By adopting the method for degrading the malodorous gas by coupling the biotrickling filter with the dielectric barrier discharge, the malodorous gas enters a buffering tank after entering a water-membrane separator to remove one part of water; after the waste gas flowing out of the buffering tank is monitored by a total hydrocarbon analyzer, the detected waste gas enters dielectric barrier discharge plasma equipment; the waste gas discharged from the dielectric barrier discharge plasma equipment is treated by an ozone analyzer to remove ozone, and then enters at least one biotrickling tower; the waste gas treated by the biotrickling tower is discharged from the biotrickling tower. By adopting the technical scheme, the problems are solved and the method can be used for degrading the malodorous gas.
