Energy-saving reciprocating sewage treatment device

The invention provides an energy-saving reciprocating sewage treatment device. The energy-saving reciprocating sewage treatment device comprises a sewage pool and a transmission belt, the surface of the transmission belt is provided with a filtering and floating support, the inner side surface of the filtering and floating support is provided with a driving box, the surface of the driving box is rotatably connected with a filtering and floating plate, the side surface of the filtering and floating plate is rotatably connected with a shaft seat, a fixed gear is arranged in the filtering and floating plate in a rotating manner. According to the energy-saving reciprocating sewage treatment device, through cooperative use of the filtering and floating support and an adjusting pneumatic rod with the filtering and floating plate, the filtering and floating plate can be rotated and adjusted, so that the resistance between the filtering and floating plate and sewage during returning can be conveniently reduced, and t
