The oil-water of alkali-surfactant-polymer flooding separation in Daqing oil field is difficult, which result in excessive oil in waste water. Aiming at this problem, the oil remover QP888 was used in the pilot experiment. The addition dosage and technologic operating parameters were gained. The research indicated that when the stirring intensity, stirring time, addition dosage, inflow and outflow, adsorbing time were 130 rpm, more than 6 min, 75 mg•L-1, 50-240 L•h-1 and 15 min respectively, the oil content of waste water was reduced from 125-156 mg•L-1 to less than 50 mg•L-1 which met to the influent water standard of filter equipment by using absorbing tank in continuous running. The technology adding oil remover and stirring was feasible under the water quality at present. The waste water treatment handling cost was less than 4.83 ￥•m-3 and could be reduced in production.
