A new type of multi-stage flotation device is used t o treat oil-bearing wastewater.the process is achieved by persing air in the bottom of the tray column and the oil-bearing wastewater is treated o n every tray of the column.the rody namic perfo rmance and ai r dispersion perfo rmance of the tray, and the ef fect of v arious operation parameters on the efficiency ofremoving oil from the wastewater are studied.
Key words: multi-stage flotation column; oil-bearing wastewater; aeration
