Pilot Study on AmOn Integrated Bioreactor for Wastewater Treatment

摘要

The pilot-scale study on AmOn integrative process was discussed in this paper. The results showed that AmOn integrative process had high efficiency on CODCr and NH4+-N removal, and the CODCr and NH4+-N removal rate were 80% and 89.5%, respectively. But the TN and TP removal rate were low, 22% for TN and 47.8% for TP. The concentration of CODCr, NH4+-N, TP in effluent were below 40mg/L, 6mg/L, 0.9 mg/L respectively, satisfying the first B level standard of “discharge standard of pollutants for municipal wastewater treatment plant”(GB 18918-2002). As well, the reason for low removal efficiency of TN and TP were analyzed, supporting for the further experiment and process optimization. AmOn integrative process had widespread prospect for application and high value for further research.
