چکیده

A benchmark for the test of control scenarios of sequencing batch reactors (SBR) used for wastewater treatment is proposed. The plant layout includes a buffer tank for wastewater storage in front of the SBR. Performance criteria based mainly on the quality of the effluent are given. The use of the benchmark is illustrated by the study of the effects on the effluent of the control of dissolved oxygen during aerated phases, of the total suspended solids concentration by manipulation of the wastage and of the management strategy of the buffer tank

Effect of aeration on nitrous oxide (N2O) emission from nitrogen-removing sequencing batch reactors.

In this study, nitrous oxide (N(2)O) emission was compared between the operations of two different sequencing batch reactors, conventional sequencing batch reactor (CNVSBR) and simultaneous nitrification and denitrification sequencing batch reactor (SND-SBR), using synthetic wastewater. The CNV-SBR consisted of anoxic (denitrification) and aerobic phases, whereas the SND-SBR consisted of a micr...
