Low C/N domestic sewage was treated in a SBR. With an operating temperature of (25±0.5)℃, NO -N accumulation rates reached 96.79%, 98.80%, and 98.78% after 69, 63, and 58 cycles, respectively. In each case, alternating modes of hypoxia/aerobic (four times), aerobic/anoxic (five times), and aerobic/a...
