The application discloses a high-efficiency and low-consumption transmission device for treating
wastewater by an
electron beam, which comprises a drainage
pipe, wherein the drainage
pipe extends below an
electron accelerator, an included angle between at least a partial
pipe section of the drainage pipe and a horizontal plane is an
acute angle, a bottom end of the drainage pipe is connected to an
irradiation effluent pool, and a top end of the drainage pipe is higher than the
irradiation effluent pool; liquid entering the drainage pipe from the top of the drainage pipe flows downward under the action of gravity, passes below the
electron accelerator, flows into the
irradiation effluent pool after being irradiated by an electron beam, and is treated by the electron beam. The drainage pipe of the application extends in a height direction and is inclined,
sewage entering from the top of the drainage pipe flows under the action of gravity and passes below the electron accelerator, and is treated by the electron beam. The transmission device mainly relies on gravity to provide
water flow power, does not need to be provided with high-power water pumps and other
electric equipment, has the advantages of reducing operation cost, reducing
noise, saving energy and reducing
energy consumption.
