Abstract

In the petroleum industry, a large quantity of oil-contained wastewater is produced every day. This kind of wastewater normally contains oil droplet from 100 to 1000ppm, which is characterized by tiny oil droplets, dispersion, stable, uneasy to reunite float. The conventional methods such as demulsification agent and heat treatment will undoubtedly increase the cost of production. Bubble column flotation was 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. In this paper, experimental study mainly attempts to find the key factors affecting the separation efficiency and utilized to improve bubble column structure and increase the separation rate. Two new physical quantities, total ventilation per unit volume of wastewater and aeration intensity were defined. Two key parameters about the degree of salinity and aeration intensity were studied separately.
