  • Suspended carriers were filled to single sludge tank. The effects of different filling proportions on the removal of maize processing wastewater were studied. The results showed that the new process could bear higher CODCr volumetric loading shock with the increase of filling proportion. With the filling proportion of 30%, more than 80% CODCr was removed when the average concentration of influent CODCr was 832.7 mg/L and the average change of CODCr was 779.6 mg/L, or with the average shock of more than 94%, in one day. The removal rate of NH4+-N was obviously improved by the carrier filling. When the filling proportion was 20%, about 90% NH4+-N could be removed, which was nearly 50% more than that without carrier filling. With the filling proportion of 30%, 90% NH4+-N could be removed stably. The carrier filling had little impact on the remove of TN with the experiment filling proportions. Additionally, it was observed that during the sludge bulking, the period for the biofilm to form on the carrier was shorter than other studies.
