The invention discloses a sterile filtration system for piperacillin sodium and tazobactam sodium for injection. The sterile filtration system comprises a filter tube, wherein an inner tube is fixedlydisposed inside the filter tube; a sterilization hole is formed in the side wall of the inner tube in a penetration manner; the outer side of the inner tube is fixedly covered with a rubber ring; a steam spraying nozzle is disposed in the rubber ring in a penetration manner; and one end of the steam spraying nozzle is movably located in the sterilization hole. According to the invention, when a filtration process of production is needed to be ensured in a sterile environment, a large amount of steam is injected into a steam sleeve from a steam generator, and the steam is injected into the inner tube from the front end of the steam spraying nozzle, so that the sterilization treatment is performed; a liquid to be filtered is injected into the inner tube from a water inlet during filtration,then a motor is driven, and a gear is driven by the motor to rotate, so that a threaded shaft is driven to rotate, and under the action of a threaded sleeve, the threaded shaft can be enabled to moveup and down while rotating, thereby changing a pre-filter plate and a sterile filter plate, and ensuring the sufficiency of the filtration of the liquid; and the filtered liquid is discharged from awater outlet.
