Rapid culture method of aerobic granular sludge for treating high-salinity wastewater

The invention discloses a rapid culture method of aerobic granular sludge for treating high-salinity wastewater. The method mainly comprises the following steps: (1) inoculating activated sludge into a reactor; (2) supplementing a saccharide carbon source into the high-salinity wastewater to prepare an induction matrix, and adding the induction matrix into the reactor as inlet water; (3) operating the reactor in a sequencing batch manner; 4) after the mycelium pellets are formed, stopping supplementing the carbohydrate carbon source, recovering the influent water into high-salinity wastewater, continuing to operate the reactor in a sequencing batch manner, and culturing the salt-tolerant aerobic granular sludge. Under the conditions of high hydraulic selective pressure and high salt stress, a saccharide carbon source is used for inducing fungal mycelium pellets to be formed, the mycelium pellets can directly adapt to corresponding high-salt environments, meanwhile, other microorganisms can be adsorbed, and th
