T he effects f the pr p rti n f starch and acrylic acid amide, different adding rder w ere investigated. T he result s sh wed t hat the pt imal rat i f starch and acrylic acid amide is 1B 2, the best fl ccula- t i n effect is PSA S + starch m dified fl cculant , the rem val eff iciency f il is 94% , w hich can reach the reinjecti n w ater standards. ey words Flocculant Oil- bearing Wastewater PolysilicAluminiumSulphate(PSAS) Starch Graft Acrylic Acid Amide , , [ 4] 515 t, 50% [ 1] , 70% ~ , , PSAS 95%[ 2] , , PSA S , , PSAS/ ( PAC) , PSAS/ ,
