| Abstract: |
| Oil sludge was treated by wet-processing equipment, optimal technological condition, such as feed quantity, time of broken and flotation, time of mud-making, pump frequency of stripping, pump frequency of flotation, first flotation time, second flotation time and cyclone frequency can be determined by comparative tests. Dosage of foaming agent, first stripping time, second stripping time and water temperature were analyzed by orthogonal test. In the optimal technological condition, oil content of mixed sand can reach 0.29%, oil content of scum can reach 70.20%. The results perfectly met the standard of GB4284-1984. |
