The invention provides an adjustable baffling lamella settler in order to solve the problems that a lamella settler is single in form, and precipitating efficiency needs to be further improved. The adjustable baffling lamella settler comprises a shell 1, a water inlet channel 2, a settling area 3,baffling lamellas 4, a clear water region 5, a water outlet trough 6, a mud hopper 7, a mud discharge pipe 8, a control rope 9, a pipeline 10, a pulley 11, a hinge wheel 12 and a handle 13. Each baffling lamella 4 comprises an upper section 41, a middle section 42 and a lower section 43. The upper ends of all the baffling lamellas 4 are hinged to an upper hinge rod 44, and the lower ends of all the baffling lamellas 4 are hinged to a lower hinge rod 45. The upper section 41, the middle section 42 and the lower section 43 of each baffling lamella 4 are of an integrated structure. Different from a traditional lamella, the baffling lamellas are formed by connecting a series of lamellas with specific included angles in series, and the settling efficiency is higher than that of a traditional lamella settler. The lamellas can be placed at vertical positions through the control rope, and lamella mud discharging is convenient.
