Experimental Study on the Advanced Treatment of Wastewater in Petrochemical Production

Hong Li

Abstract

In this paper the removal effects of each advanced treatment technique on organic pollutants in oil extraction are investigated by combining biochemical process with physicochemical one.The results show that the removal rate of COD is 49.8% when 0.5mg/L of PAM is applied and 20mg/L of PAC is added,COD_(Cr) of ozonation effluent doesn't decrease obviously and the removal rate of COD can keep above 60% by using biological activated carbon tower.The total removal rate of COD can reach more than 85% after advanced treatment.So this combined technique has a bright future in advanced treatment of oil extraction wastewater.
