SBBR setup and its operation
As shown in Fig. 1, the DEAMOX process was operated in an SBBR reactor (working volume: 10.0 L). The reactor included a pH meter (WTW Company, WTW 3310, Munich, Germany) for monitoring the pH value and a heating rod for maintaining a stable operational temperature at 30 ± 5 °C. Two separated peristaltic pumps were utilized to supply influent substrates with 4.0 L synthetic water per cycle and carbon source to the reactor, respectively.
As shown in Fig. S1, the carriers were strung together by
Nitrogen removal performance of the DEAMOX-SBBR process
The DEAMOX-SBBR process was successfully operated for more than 240 days for biofilm formation. As shown in Fig. 2b, the reactor seed sludge quickly adapted to the high strength wastewater, with a maintained TN removal efficiency of 97.4 % in phase I. The effluent NH4+N, NO3−N and NO2−N concentrations remained in the range of 0.12–12.63 mg L−1, 0–11.5 mg L−1 and 0.05–7.93 mg L−1, respectively. During phase I, carriers were added into the SBBR to form biofilms and promote anammox bacteria
