Abstract
After emulsification, oil droplets are dispersed, stable and uneasy to coalesce in wastewater. The conventional methods such as demulsification agent and heat treatment will undoubtedly increase the cost of production. Bubble column flotation is attracted more attention by oil companies for its characters of cost-effective, simple structure, high efficiency and no secondary pollution, etc. Oil removal efficiency is affected by many parameters. Pressure, split ratio, salinity and aeration intensity are selected as four key facts to study. Two new physical quantities, comprehensive oil removal rate and intensity of flotation are defined in this paper. Experimental study mainly attempts to find the key factors affecting the separation efficiency and to improve bubble column structure and increase the separation rate.
