doi:10.12052/gdutxb.190032

Abstract

Abstract: The Computational Fluid Dynamics (CFD) module in COMSOL Multiphasic software is used to construct the models comparing simulation schemes and the analysis results of a series of flocculation tanks in Z City's water plant. It is found that the structure and size of existing flocculation tank are unreasonable in design, which has a bad effect on flocculation, and leads to flocs being observed at the end of the sedimentation tank. Based on the calculation results, three transformation schemes are designed and proposed, which are supplemented by structure modeling, flow analysis and calculation optimization, and the advantages and disadvantages of each transformation scheme are listed, thus providing the basis for the actual reconstruction project. Finally, the application and effect of COMSOL-CFD technology in the schemes design and modification of water treatment are discussed, with practical conclusions of COMSOL-CFD in water treatment engineering obtained.

Key words: COMSOL-CFD, simulation calculation, flocculation, water supply structure, reconstruction design
