Coke Plant Wastewater

Conventional treatment of coke plant wastewater includes pre-treatment, biological treatment and coagulation sedimentation. Due to the presence of refractory and inhibitory compounds, the conventional biological treatment is not efficient in removing COD to meet the effluent standard. The improving methods of the removal efficiencies were discussed.

Coke Plant Wastewater

For removing COD and NH3-N from high-strength coke-plant wastewater, studies were conducted in a lab scale, continuous flow system, in which anaerobic, anoxic and oxic units were included. The results have shown that the effluent COD and NH3-N of A-A/O system could be less than 78 mg/L and 4.7 mg/L respectively when the influent COD and NH3-N were higher than 1200 mg/L and 240 mg/L respectively at a total HRT of 36 hrs. Moreover, the total nitrogen of wastewater was removed by 49%. It is concluded that A-A/O system is efficient for coke-plant wastewater treatment and the anaerobic process has played very important role in the system.
