| Zusammenfassung: | The invention belongs to the field of water treatment, in particular to a deep oil removing and purification method for refinery stripping purified water. The method comprises the steps of: removing dispersed oil and suspended matter with the particle size larger than 10 um in the refinery stripping purified water through a pottery filter tower, then separating suspended oil, part of emulsified oil and colloid and suspended matter which have particle size greater than 1 um in the obtained refinery stripping purified water in a retaining mode after the obtained refinery stripping purified waterenters a first-stage fiber membrane, and finally introducing the refinery stripping purified water obtained after the first-stage fiber membrane into a second-stage fiber membrane to separate the emulsified oil and colloid and suspended matter which have particle size greater than 0.1 um from the obtained refinery stripping purified water after the first-stage fiber membrane in a retaining mode.According to the deep oil |
