Abstract

The invention provides an aerobic granular sludge water treatment integrated device, and relates to the technical field of water treatment.The aerobic granular sludge water treatment integrated device comprises a pool body, a water inlet and an air inlet are formed in the pool body, the air inlet is connected with an air supply device, a plurality of installation positions are arranged in the pool body, blocking plates are installed at the installation positions, and a circuitous water channel is formed between the pool body and the blocking plates; the water inlet is formed in the starting point position of the bottom of the water channel, the pool body is provided with a suction port, the suction port is connected with a suction device, in the rising process of sewage, under the action of the blocking plate and the air inlet, the sewage forms surging similar to sea waves, generated hydraulic shearing force enables sludge floccules to continuously roll over to form aerobic granular sludge, and the aerobic granular sludge is discharged out of the pool body. Meanwhile, the aerobic granular sludge is large in specific gravity and high in settling velocity, does not break through the top of the tank, and continuously circulates in the reactor.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an integrated device for water treatment of aerobic granular sludge. Background technique [0002] When running an aerobic up-flow sludge bed, ordinary activated sludge will spontaneously agglomerate under specific operating conditions to form small particles of different shapes, with a particle size distribution between 2 and 8 mm, which the researchers named it. For aerobic granular sludge, the treatment of sewage at this stage will be applied to the FBBR (fixed bed biofilm reactor) or MBBR (moving bed biofilm reactor) process. Whether it is the FBBR process or the MBBR process, a carrier needs to be put in. The collision and shearing of the carrier in the water make the air bubbles smaller, increase the utilization rate of oxygen, and the cost is high. If the aerobic granular sludge can be used, so that it can play a certain role in place of the carrier, the cost will ...
