| Abstract: | In order to solve the problem of removal NH4＋-N in the treatment of low C/N ratio wastewater, a new kind of carbon polymer carrier was developed, the removal of NH4＋-N by biofilm with the carrier was studied. Factors affected the system of simultaneous nitrification and denitrification, such as HRT, pH, DO and temperature, were investigated. The results indicated that C/N=4, pH=8, DO=1mg/L, HRT=6h, T=24 ℃, the removal rates of NH4＋-N and TN were 90% and 70%, respectively. |
