Abstract A pilot-scale internal circulation-anoxic/oxic (IC-A/O) coupling reactor was performed for soybean protein wastewater treatment. Results indicated that after the IC-A/O coupling system, the CODcr (8000–10,000 mg·L−1) and NH3-N (250–270 mg·L−1, decomposed… Click to show full abstract
Abstract A pilot-scale internal circulation-anoxic/oxic (IC-A/O) coupling reactor was performed for soybean protein wastewater treatment. Results indicated that after the IC-A/O coupling system, the CODcr (8000–10,000 mg·L−1) and NH3-N (250–270 mg·L−1, decomposed from the organic nitrogen) in influent of soybean protein wastewater was greatly reduced to 70–90 mg·L−1 and
