%X The effects of composite inorganic polymer flocculent (IPF), organic polymer flocculent (OPF) quantity and settling time on the removal of turbidity and total iron from oil field wastewater by means of coagulation were investigated. Optimized parameters on the coagulation sedimentation process by Box-Behnken centre-united experiment design and response surface methodology (RSM) to establish a predictive polynomial quadratic model were found to be IPF dosage of 152.15 mg/L and 143.84 mg/L, OPF of 4.14 mg/L and 4.32 mg/L, settling time of 11.77 min and 11.22 min. The experimental results of the removal rates of turbidity and total iron under the optimized condition presented better agreement with the predicted values and the deviation error was only 3%~5%. In order to compare the multivariate quadratic regression equations of turbidity and total iron, mean interpolation method was used and the two sets of optimized conditions proved to be suitable.
