Abstract:

Three SBR reactors were used to inoculate activated sludge from sewage treatment plants in this experiment. R1was used high SGV continuous aeration, R2 was used low SGV continuous aeration, and R3 was used low SGV intermittent aeration to cultivate aerobic granular sludge in actual domestic sewage, and explore the effect of different SGV aeration conditions on the formation of aerobic granular sludge and the effect of system processing. After 120 days of incubation, the particle sizes of R1, R2 and R3 were (754±78)μm, (812±86)μm and (1183±93)μm, respectively. The denitrification and phosphorus removal effect of R3 was better than that of R1 and R2. The results show that the application of low SGV intermittent aeration strategy can realize the cultivation of aerobic granular sludge in actual domestic sewage, and the system had good denitrification and phosphorus removal performance. The proportion of denitrifying phosphorus-removing organisms (DPAO) to phosphorous accumulating organisms (PAO) was 24.75%. © 2021, Editorial Board of China Environmental Science.
