Title: Synthesis and Property of Multifunctional Cationic Flocculants for the Treatment of Oil Field Wastewater

Thus, according to the properties of oil field wastewater, the multifunctional flocculant (PDTC)was prepared with the material of amine, CS_2 and metal salt. The flocculation performance was studied by treating oil field wastewater. It was shown that the rates of removal oil, SS, COD_(Cr) and chrom in oil field wastewater are 89.2%, 91.3%, 71.3%, 93.1% respectively, when the dosage of this reagent is 25?mg/L. By comparison with others flocculants, the performance of the PDTC is stable, and the applicable range of temperature and pH are wide relatively. The rates of removal oil of the PDTC are higher in treatment of the oil field wastewater. Aside from these, this flocculant PDTC has multifunction of bactericidal action, delaying corruption action and inhibiting scale action and so on.Read More
