In order to protest water resource system

save energy and achieve domestic production of centrifuges

the sewage treatment centrifuges were developed. A overview of related researches both at home and abroad are given and the design target of the centrifuge is determined. The mathematical models of structure parameters and process of contrifuge are set up to optimize the result. The design and research about the tumbler

the screw conveyer and the band differential of contrifuge are carried out. A kind of new-style sewage treatment scroll discharge settlement centrifuge based on band is developed. Its practical effect is better and its performance meets the design requirements.
