| Abstract: | Objective ] The research aimed to study treatment effect of the slightly polluted wastewater with different C/N by macroporous pol- yurethane carrier immobilized microbe. Method ] Macroporous polyurethane carrier immobilized microbe was used to treat slightly polluted wastewater, and influence of the different C/N on aerobic denitrification effect of the slightly polluted wastewater was inspected. Result] Un- der the C/N of 7.5, removal rate of the NH4 -N after 8 h by SBBR reached 99.8%, and NH4＋ -N concentration in effluent was 0.05 mg/L. Conclusion] Macroporous polyurethane carrier immobilized microbe had good treatment effect on slightly polluted wastewater. |
