A Pilot Study of Municipal Wastewater Treatment by Integrated A_mO_n Process

Abstract:

This pilot study discussed the treatment efficiency of municipal wastewater with an integrated AmOn process. Referential data basis were given to develop integrated AmOn Process with high efficiency, reliability, and low energy consumptions. Results show that the efficiency of CODCr and NH3-N removal in pilot-scale system is higher than that in bench-scale test when the water temperature of influent is above 15°C. When the water temperature is below 15°C, the efficiency of CODCr and NH3-N removals of integrated AmOn process become lower, but the treatment efficiency of TN and TP is not affected by lower temperature. However, the whole process can be updated to an A-AmOn system by adding an anaerobic zone before the AmOn process. Hence, the nitrification, denitrification and dephosphorus in the new system could be enhanced, as well as the CODCr removal. The optimal sludge recycle ratio in the A-AmOn system was also studied in this paper. Results indicate that dephosphorus in this system become high when sludge recycle ratio is 3.0; when the ratio is 2.0, the denitrification is higher than that of 3.0. Sludge recycle ratio has less effect on CODCr and NH3-N removal in A-AmOn system.
