Two-stage sequencing batch reactor aerobic granular sludge sewage treatment process and equipment

The invention discloses a two-stage sequencing batch reactor aerobic granular sludge sewage treatment process and equipment. The process comprises the three steps: a, primary granular sludge sewage treatment; b, secondary activated sludge process sewage treatment; and c, sludge collecting and drying. The equipment comprises a reactor area A and a reactor area B; the reactor area A is provided witha first water inlet pipe and a first composite filler, the reactor area B is provided with a water outlet pipe, a connecting pipe is arranged between the reactor area A and the reactor area B, and aeration mechanisms are arranged in the reactor area A and the reactor area B. According to the invention, granular sludge is rapidly cultured by adopting intermittent water feeding and intermittent aeration modes to enhance the sewage treatment efficiency, and a carbon source is saved by adopting a two-stage water feeding mode; meanwhile, the reactor is ensured to have the characteristics of strongimpact load resistance, h
