Abstract Wind effects on P control by two P inactivation agents (thermally-treated calcium-rich attapulgite and lanthanum modified bentonite (Phoslock)) using Y-shaped sediment resuspension generation apparatus was studied. The results indicated that addition of P inactivation agents could solidify the surface sediment and reduce the erosion depth accordingly when suffer from frequent wind disturbance. Furthermore, the suspended particulate matter (SPM) and soluble reactive phosphorus (SRP) also could be reduced compared with control treatment. The forms of calcium bounded P and inert P were also increased with the addition of P inactivation agents. Strong wind increased sediment erosion depth, concentrations of SPM and SRP in overlying water and sediment mobile P content when compared with moderate wind disturbance. The percentage of calcium bounded P and inert P in sediment under the influence of strong wind was also reduced in comparison to moderate wind. This results indicated that even wind can exert great influence on sediment P inactivation while which still could be used in shallow eutrophic lake restoration.
