Sewage treatment vehicle

The utility model discloses a sewage treatment vehicle, which comprises an automobile power assembly, the input end of the power takeoff is connected to the automobile power assembly; the speed reducer is provided with an input shaft, a first output shaft and a second output shaft, and the input shaft is connected with the output end of the power takeoff; the generator is connected to the first output shaft; the stacked screw dehydrator is provided with a screw shaft, and the screw shaft is connected to the second output shaft. According to the sewage treatment vehicle, the power takeoff directly outputs part of power of the vehicle power assembly to the screw shaft through the second output shaft, the power does not need to be converted into electric energy, then the electric energy is used for driving the screw shaft of the stacked screw dehydrator to rotate, and energy consumption of kinetic energy-electric energy conversion is saved. The sludge dewatering vehicle can be applied to the field of sludge dewa
