In view of the difficulties involved in recovery fluid treating, we developed the complete technology of oily wastewater treatment in the core of hydrocyclones, and devised three kinds of complete plans, in which we used two kinds of hydrocyclones that were serially connected with filtering equipment by treating the recovery fluid of oil\|well. After filtering and separating, the concentration of oily water was reduced to 1.9 and 3.5 mg·L -1 , with the testing target achieved. During the process of oily...
