Pilot-scale investigations have been carried out to assess the feasibility of treating wastewaters from a by-product coking plant in a coupled denitrification - nitrification biological fluidized bed process. The process can achieve complete nitrification and denitrification of undiluted coke plant wastewater at a total system hydraulic retention time (HRT) of 16 h. Comparable data for conventional suspended growth systems treating similar wastewaters have shown a required total system HRT of up to 60 h for a similar degree of treatment, and dilution or addition of low levels of powdered activated carbon were required to maintain a consistent level of nitrification. Removal of conventional contaminants including organic carbon, phenolic compounds and thiocyanate was consistently greater tha 90% in the fluidized bed system.
