Evaluation of SBBR with Shell Carrier for Wastewater Treatment
The paper presented the performance of sequential batch reactor (SBR) and sequential batch biofilm reactors (SBBR) for simultaneous carbon, nitrogen and phosphorus removal from synthetic brewery wastewater. SBR contained only suspended biomass, while SBBR contained suspended biomass along with shell carrier, which are waste products from mariculture. Evaluation of performance of SBR and SBBR was done by operating two laboratory scale reactors. The cycle of operation was set as 12 hours, including 10 hours of aeration, 1 hour of sedimentation, and 1 hour of decanting and feed. The two reactors were operated with three loadings of 0.71, 0.85, 1.01 kg COD/m3.d. SBBR gained 94.2%, 97.6% and 97.6% of COD removals; 57.6%, 92.2% and 98.2% of ammonia nitrogen removals; 86.9%, 92.2% and 87.7% of phosphorus removals, respectively. Compared to SBR, ammonia nitrogen and phosphorus removals in SBBR improved 25.9 and 22 percentages, respectively. Shell possessed ideal performance for biofilm attachment, provided plenty of calcium ions, as well as strengthens the removal of phosphorus; at the same time, SBBR with shell carrier had strong ability of organic loading shock resistance.
