Study on the Treatment of Cold Rolling Wastewater by Using Bio-Fluidized Bed

Abstract:

Article Preview

Cold rolling wastewater is very difficult for treatment with high oil content, complex composition, toxicity and other characteristics. In the conventional treatment process, the most widely used methods are ultrafiltration(UF), gas-energy-management(GEM) and membrane bioreactor(MBR). In this study, we used the biological fluidized bed to treat the cold rolling wastewater, which made the bioaugmentation apply to anaerobic biofilter and biological fluidized bed (BF-BFB) combined process, and the optimal process parameters were determined. The contents of COD and NH4+-N were 3276.8mg/L and 67.65mg/L in inflow water, and after treatment, they were reduced to 108.8mg/L and 6.36mg/L, respectively. The removal rates of COD and NH4+-N were 96.68% and 91.01%.
