Intelligent water distribution large-torque multi-stage waterwheel driven biological rotating disc system

The invention discloses an intelligent water distribution large-torque multi-stage waterwheel driven biological rotating disc system, relates to the technical field of sewage treatment, and solves the technical problems that existing village domestic sewage aerobic treatment process facilities are large in occupied area, multiple in electromechanical equipment, high in energy consumption, unstable in operation and complex in maintenance. According to the technical scheme, through the multi-point adjustable water distribution design of a top-end water distribution pool and a tail-end water distribution pool, intelligent and accurate control over the flow proportion of driving water, purified water, backflow water and outlet water is achieved. Meanwhile, purified water and driving water can be combined and lifted through the top-end water distribution tank, only one sewage lifting device needs to be adopted for the front water inflow unit, and the device cost and energy consumption of the treatment process are
