Abstract

In sewage treatment, the sewage whose carbon and nitrogen(C/N) ratios is less than 8 is defined as low C/N ratio sewage. This study contrasts the treatment effects under different C/N ratios in aerobic membrane bio-reactor. The experiment is performed in the following conditions: Temperature is from 7 to 30 ; pH is from 6.4 to 7.9; CODcr is from 114.8 to 400.0mg/L; TN is from 28.9 to 50.9mg/L; NH4+-N is from 16.8 to 29.8mg/L. The range of outlet CODcr and NH4+-N are from 8.78 to 20.78mg/L and 3.1 to 7.0mg/L respec-tively, and the range removal rates of them are from 82.98 to 97.49% and 67.3 to 86.9% respectively. Both two indexes achieve A level of dicharge standard in "Discharge standard of pollutants for municipal wastewater treatment plant" (GB18918-2002). But the TN in outlet cannot reach this standard.
