| Abstract: | The best doping rate and heat treatment temperature were obtained.Oil-field wastewater was treated by flocculation combined with nano-TiO2 photocatalytic oxidation,and process of the treatment was studied.The results of experiment showed that at the best conditions：the ratio of PFS and TiO2 is 1∶0.1;dosage to 0.8 g/L;pH in the range of 7 to 9;the reaction time of 40 minutes.The removal efficiency of oil content and suspended solids were 94.1% and 96.4% respectively.Under the best treatment process,the treated wastewater reached re-injection standards. |
