Abstract—An SBR process in two reactors with mid-oxidation by N. Two SBR reactors were used to separate the two processes
ozone and powder activated carbon adsorption is used for the to decrease the influence of aeration on anaerobic bacteria

anoxic stage and oxic stage are 24h, 3h and 1h, respectively. With dissolved oxygen concentration. The ozone used for mid-
