| Abstract: | Treated wastewater by conventional treatment process is difficult to meet standard of affusion to underground in oil field. By operation of UF membrane module to advanced treat oily wastewater, water quality of the effluent was up to the affusion criteria. End flow was adopted during system operation, with optimum conditions including operation period of 12 minutes, linear velocity of forward 0.4m/s and time of 10s, flux of backwash 150L/(m2·h), time of 10s and inlet pressure 0.1Mpa. In chemical cleaning process, surfactant and acid and alkaline were used to obtain the optimum cleaning effect. |
