Abstract

The concentration of DO is a critical factor for the iron-manganese co-oxide oxide film coating on the quartz sands to remove the high concentration of ammonium from groundwater, and oxygenating at the bottom and the one third of the bottom in a pilot-scale filter was used to ensure the sufficient dissolved oxygen. Results showed that removal capacity of ammonium was increased obviously after oxygenating compared with non-oxygenating(1.5mg/L). When the positions of oxygenating were at the bottom and the one third of the bottom, the maximum removal concentrations of ammonium were 3.7 and 4.3mg/L, respectively, and the filtering velocity was 8m/h. It indicated that the catalytic activity of the co-oxide film was greatly improved, and the removal efficiency of ammonium was highly enhanced by increasing the dissolved oxygen.Besides, the characterizations of SEM and EDS for the oxide film showed that the morphologies and elements were rarely changed before and after oxygenating.

Key words： dissolved oxygen catalytic oxidation oxygenating high concentration of ammonium filtering velocity
