Abstract
Emergency disposal combined technology of sorbent cotton intercept and powdered activated carbon (PAC) adsorption was researched. The removal effects of petroleum pollutants individually treated by sorbent cotton were analyzed. The influencing factors of PAC adsorption to deal with petroleum pollutants, including PAC dosage, oscillation frequency and oscillation time, were investigated. The results showed that removal efficiency increased with increasing PAC dosage. When PAC dosage reached 50mg/L, the remaining concentration of petroleum pollutants met the standards. And after oscillated for 120min, the total removal efficiency increased to more than 99%.
