Abstract:

In view of the oily wastewater produced by the oilfield, an advanced treatment unit with sand filtrationactivated carbon immobilized microbial agents was designed to study the removal effect of oil and SS pollutants in sewage. The results indicated that when oily wastewater passed through the filtering device, the concentrations of oil and SS in the final effluent was 3.25 mg·L-1 and 26 mg·L-1, respectively. In addition, the oil could be removed by activated carbon immobilized microorganism and the removal rate could reach 35.6% within 10 d, which indicates that this kind of immobilized microorganism technique has a good potential in the field of oily wastewater treatment.

Key words: oily wastewater, activated carbon, sand filtration, immobilized microbial agents
