In this paper, the mechanical models and finite element models are established respectively for the load-bearing beam of mud scraper in a type of second sinkbasin and a type of horizontal flow basin utilizing the finite element analysis software that developed by authors for the sewage treatment equipment load-bearing beam, these beams' modeling method and the optimization method are discussed, and finite element analysis and optimization design are calculated for these beams. The result shows that the finite element models are appropriate and these beams lightened by 27.7%. The result is very good and it has important actual project meaning.
