چکیده
|
Background: simultaneous nitrogen, phosphorous and cod removal in a pilot-scale enhanced sequencing batchreactor (esbr) was investigated.methods: the reactor consisted of a pre-anoxic zone and internal recycle and was fed with synthetic wastewater.the study was performed by operating the reactor in 6-hour cycles in three different operational modes during atime frame of 279 days.results: under the best operational conditions, the average removal rate of cod, tn, and tp were obtained as93.52, 88.31, and 97.56%, respectively.conclusions: a significant denitrifying phosphorus removal (more than 80%) occurred at run1 and 3 which startedthe cycle under anoxic condition.
