Abstract

The invention discloses an upflow aerobic granular sludge reactor, which relates to the technical field of aerobic granular sludge reactors, including a reactor tank body, a water distribution system is provided at the bottom of the reactor tank body, a water outlet pipe is provided at one side of the top of the reactor tank body, and a three-phase separator is provided in the middle of the reactor tank body, and the three-phase separator divides the reactor tank body into a main reaction zone, a three-phase separation zone and a fine treatment aerobic reaction zone from bottom to top; an aeration system is provided above the water distribution system in the main reaction zone; a steam-water separator is provided at the top of the reactor tank body; and a circulating pump is also included, the water outlet end of the circulating pump is connected to the water distribution system, and the water inlet end is respectively connected to the three-phase separation zone and the fine treatment aerobic reaction zone to form an external circulation system. The present invention can realize the formation of aerobic granular sludge in the reactor under a continuous flow state, and stably operate. Compared with traditional aerobic bioreactors, the aerobic granular sludge reactor has a higher sludge concentration, a lower investment cost, a better denitrification effect, and more energy saving.
