Polyaluminium chloride reinforced aerobic granular sludge inclined tube reactor and application method thereof

The invention discloses a polyaluminium chloride reinforced aerobic granular sludge inclined tube reactor and an application method thereof. The polyaluminium chloride reinforced aerobic granular sludge inclined tube reactor comprises an aerobic granular sludge main reaction zone, a sludge bucket and a polyaluminium chloride liquid storage tank. The aerobic granular sludge main reaction zone is ahollow cylinder, wherein a perforated plate is arranged at the bottom of the aerobic granular sludge main reaction zone, and the sludge bucket is connected to the lower surface of the perforated plate. Two groups of honeycomb inclined tubes are arranged in the aerobic granular sludge main reaction zone, and the inclined tubes are arranged in opposite directions. The reactor disclosed by the invention adopts an SBR (sequencing batch reactor) operation mode; in a reaction period, while sewage enters the aerobic granular sludge main reaction zone from the upper part, a polyaluminum chloride solution in the polyaluminum c
