The invention relates to the technical field of airport transport vehicles, in particular to a manual emergency blow-down device for an aircraft sewage truck, which comprises a ball valve, a driving assembly and a manual assembly, the manual assembly comprises a valve opening plate and a labor-saving rod, when the aircraft sewage truck runs normally, the ball valve is operated by the driving assembly to control automatic blow-down, and when the truck is in an abnormal state, the manual assembly is operated by the driving assembly. When the driving assembly stops being used, the labor-saving rod is inserted into the power-assisted connecting port, the labor-saving rod is rotated to drive the valve opening plate to rotate, then a valve element of the ball valve is rotated, the ball valve is opened for pollution discharge, different power-assisted connecting ports can be selected according to needs to open the ball valve for pollution discharge, the automatic pollution discharge requirement and the manual pollution discharge requirement are met at the same time, and manual emergency pollution discharge can be achieved in the abnormal state of the vehicle. The manual emergency pollution discharge operation is simple and convenient, the valve opening plate is provided with a plurality of power-assisted interfaces, a lengthened labor-saving rod is configured for operation, labor is saved, remote operation is achieved, and sewage is prevented from being splashed to the body of an operator.
