Abstract
In order to adapt the high-efficiency clarification tank to the switch of the raw water from high turbidity to low turbidity, CFD was used to simulate the overall tank body, and optimization measures were proposed. The three-dimensional simulation results showed that if the optimized partition clarifier was used to treat raw water with low turbidity, the velocity distribution and the sediment distribution were similar to the raw water with high turbidity in the transition section between the flocculation tank and the sedimentation tank. But the distributions were obviously more uniform. The floc flow ratio and water flow ratio of hole 1 to hole 2 were both higher than 90%, which could achieve uniform distribution of water and flocs.
