Abstract
The inverted umbrella aerator is the key equipment of biological wastewater treatment technology, which have the effects of oxygenation, mixing and plug-flow. the design and optimization of the mixing impeller is most important to the efficiency of oxygenation.In this paper, the solid modeling and finite element analysis and optimal design of aerator blades was made based on the study of the oxygenation mechanism.Firstly, the working process of the blades have been studied through solid modeling, mesh generation and finite element analysis process, and the stress-strain finite element analysis was offered based on Nastran, which identified the weak links in the leaves. And more, the optimize and improve designs for the production was made,which set the foundation for the manufacture of the blades.
