Abstract：Asacommonlyusedadvanced treatment proces，theoperating principleofhigh-effciencysedimentation tanks isakeyconcern inthe watertreatment industry.At present，researchoneficientsedimentationtanksathomeandabroad mainly focusesonthe selectionanddosage oflocculantsand coagulants，reactionresidence time and otherparameters， however，thereisstillalackofresearchontheinfluenceof mixingandstiring hydraulicparametersonthecoagulationand sedimentationefect.Takingasewage treatmentplantinHaikoucityastheresearchbject，theinfluenceof thevelocity gradientandcirculatingflow state formedbytheflocculationsectionstiringontheoperating efectis investigatedthrough simulationexperimentsand hydraulic models.Research has found thatbychanging the shapeof the flocculationagitator andincreasingtheheightoftheflocculationguidetube，theflowstateinthereactiontankcanbeoptimized，andthevelocity gradientand circulationmultiplesofwatervolume increasehavebeen enhanced.Aftertheimplementationoftherenovation， thetreatmenteficiencyissignificantlyimproved，andthetotalphosphorusconcentrationintheefluentdecreasesby7.69 % ， asa phosphorus removal agent，the consumption of polyaluminum chloride decreases by 8.83% ：
