A sequencing batch reactor (SBR) enhanced with low-intensity ultrasound was designed to study the removal of nitrogen under different carbon-nitrogen (C/N) ratios. The results showed that the removal efficiencies of CODCr and nitrogen were inversely proportional to C/N ratios. The CODCr of the effluent in the control reactor (CR) and the low-intensity ultrasound-enhanced reactor (UER) were lower than 40 mg L(-1). With a decrease in C/N ratio, the NH4(+)-N removal load of the CR showed little… CONTINUE READING
