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