Treatment of Ammonia-Rich Swine Wastewater Using a Novel IOC-SBBR Process

Abstract:

Article Preview

To establish a cost-efficient wastewater treatment system for the ammonia-rich swine wastewater, a combined process consisting of Internal and outer Circulation (IOC) anaerobic reactor and Sequencing Batch Biofilm Reactor (SBBR) was developed in this study. The combined process could remove about 91.7% of COD and 86.4% of NH4+-N, but TN removal efficiency was undesired, the average TN removal rate was only 28.5%. The optimization of SBBR operation mode to increase the oxygen - anoxic alternating frequency was conducive to the combined process of COD, NH4+-N and the TN removal rate reached 95.6%, 95.4% and 78.6%, respectively. The combined process has high removal efficiency of high ammonia and organic wastewater, is attractive for the treatment of wastewater containing high strength ammonia and carbon.
