Method for rapidly culturing aerobic granular sludge based on flexible net rope promoter

The invention discloses a method for rapidly culturing aerobic granular sludge based on a flexible net rope promoter, and belongs to the field of environmental protection and sewage treatment. The method related to by the invention comprises installing a multi-layer flexible net rope promoter in a vertical direction in an agglomeration central forming area of aerobic granular sludge, and microorganisms are mainly propagated on the net rope surface of the net rope promoter. The domestic sewage forms a flow-around shear force through flexible net ropes on which the microorganisms grow, and a negative pressure area and a Karman vortex street flocculation area are formed behind the ropes, so that the flexible net ropes vibrates regularly. With the combined action of the air water, the hydraulic shear force to the surface of the net ropes is increased, and the microorganism is promoted to fall off, so that an agglomeration center is formed for the formation of subsequent granular sludge, and quick formation of the
