Study on Using CBF to Treat High Nitrogen and Low Carbon Wastewater

Abstract:

This study puts forward the Combined Biological Filter (CBF) as a new type of BAF for advanced treatment of industrial wastewater by changing its position of aeration, particularly for treating high nitrogen with low carbon wastewater. A chemical fertilizer plant is selected to put this set of CBF device after its wastewater treatment station. Methanol is used as external carbon resource for this CBF system. Operating parameters, such as the hydraulic loading rate and C/N ratio, are discussed to determine optimal ones: 0.64m³/ (m²•h) and 4:1. Path analysis is recorded to find different contribution of anoxic and aerobic zones of CBF reactor, and different working conditions are compared to find the best performance. CBF process could find further applications and improvement in engineering practices.
