Abstract
The present disclosure belongs to the technical field of sewage treatment, and discloses a method and system for enhanced culture of aerobic granular sludge. The system includes a reaction tank, a water inlet and outlet unit, an aeration unit, and a sludge discharge unit. The water inlet and outlet unit includes a water inlet pump, a water inlet electric valve, a liquid flowmeter, a sewage uniform distribution treatment device, buffers, a water drainage pipe, and a water drainage electric valve. The aeration unit includes a blower, microporous aerators, and a gas flowmeter. The sludge discharge unit includes sludge discharge pumps, a sludge discharge pipe, a sludge discharge electric valve, and a sludge concentration meter. In the present disclosure, a multi-point uniform water distribution method is used. When the flow rate of influent water is adjusted, sewage slowly and uniformly flows through a sludge layer from the bottom of the system, so that the concentration of organic matter in raw water is prevented from being rapidly reduced by rapid single-point water intake, the utilization rate of the organic matter in the sewage is increased to the maximum extent, and the efficiency of the system is improved.
