Numerical Simulation and Application of Swirl Grit Chamber Based on Initial Rain Water Quality

Abstract

To optimize the operating conditions of the swirl grit chamber, based on the Fluent simulation, the initial rain runoff and water quality of the Binhai Industrial Cluster, numerical simulation and actual methods were used to track the sand particles. Compared with the existing test, results verified the feasibility of the model. Actually, the sand removal rate can reach 55%~90%, which is close to the predicted results of the model; the removal rate of particles with 100μm can reach 73.75%, and the removal rate of particles with 50μm can still reach 45.48%.
