In this paper, adsorption method for oily waste water treatment exists in the depth of the problem of low adsorption capacity of adsorbent start the study. Through a variety of absorbing materials for low concentrations of oily wastewater treatment effect comparison found that the handling of modified graphite flake the best results. Article investigated pH, temperature, salinity and velocity and other factors on exfoliated graphite with low concentrations of oily wastewater treatment effects. Studies have shown that: 30 ¡æ, flow velocity in the 80 BV / h when a volume of expanded graphite layer under the 2570 can handle the volume of wastewater, effluent oil content of less than 9 mg / l.
