METHOD AND SYSTEM FOR STRENGTHENING AEROBIC GRANULAR SLUDGE CULTURE

The present invention relates to the technical field of sewage treatment. Disclosed are a method and system for strengthening aerobic granular sludge culture. The system comprises a reaction tank, a water inlet and outlet unit, an aeration unit, and a sludge discharge unit, wherein the water inlet and outlet unit comprises a water inlet pump, a water inlet electric valve, a fluid flowmeter, a sewage uniform distribution and treatment apparatus, a buffer, a drain pipe, and a drainage electric valve; the aeration unit comprises a blower, a microporous aerator, and a gas flowmeter; and the sludge discharge unit comprises a sludge discharge pump, a sludge discharge pipe, a sludge discharge electric valve, and a sludge concentration meter. According to the present invention, a multi-point uniform water distribution mode is used, such that sewage flows through a sludge layer slowly and uniformly from the bottom of the system by adjusting a water inlet flow speed, rapid dilution of the concentration of organic matte
