- Abstract
Simultaneous removal and recovery of phosphorus (P) from municipal wastewater has been promoted as a global resource strategy. To improve the removal and recovery rate of phosphorus, the integrated role of anaerobic/aerobic cycle duration (TCD) and the empty bed retention time (TEBRT) on phosphorus removal or accumulation was observed for 9 months in a bench-scale continuous alternating anaerobic/aerobic biofilter system (CAABF). The study found that phosphorus accumulation deficiencies frequently occurred in the CAABFs, resulting from the over extension of TCD after net phosphorus accumulation rates were maximized. In addition, the effect of TCD on phosphorus accumulation efficiency was highly dependent on TEBRT. A simplified empirical model was developed to elucidate the interrelationship between TCD, TEBRT and total phosphorus (TP) accumulation in the biomass.
