Cell culture waste liquid treatment system

The utility model discloses a cell culture waste liquid treatment system which comprises a negative pressure aspirator, a waste liquid container, a cell culture waste liquid suction pipeline, a waste liquid container exhaust pipeline, a pedal switch and a liquid suction gun head. A cell culture waste liquid suction pipeline, a waste liquid container, a waste liquid container exhaust pipeline and a negative pressure suction device are sequentially connected from a liquid suction gun head to form a closed waste liquid suction system, and then the negative pressure suction device is controlled to run or stop through a pedal switch, so that the suction operation of the cell culture waste liquid is performed. According to the utility model, the pressure of the negative pressure aspirator can be set in advance according to actual requirements, the negative pressure stability in the waste liquid container is ensured, meanwhile, the operation state of the negative pressure aspirator is flexibly controlled through the
