The present invention belongs to the technical field of sewage treatment, and discloses a sewage deoxidation and dephosphorization treatment device and method. The device includes a PE filler module and a logic operation circuit module; the PE filler module is arranged inside a stainless steel reactor, including a PE filler and an anode plate arranged between the PE fillers; the logic operation circuit module is arranged in a PLC control box together with a power supply; the positive and negative poles of the power supply are respectively connected to the anode plate and the outer shell of the stainless steel reactor; the logic operation circuit module is connected to a pressure gauge and a power supply arranged on the water inlet pipeline of the stainless steel reactor through a signal cable for signal and control. The device of the present invention can be applied to a sewage treatment system with high dissolved oxygen in the inlet water and a large phosphorus load, and is arranged between the MBR process and the deep treatment unit to ensure efficient denitrification and dephosphorization treatment effects.

The utility model relates to a kind of ecological system of reinforcing three-surface riverway denitrification and phosphorus removal, comprising: the cascade dam body being arranged in three-surface riverway and intercepting water body, ecological filter cage is arranged in the upstream river reach of cascade dam body in three-surface riverway, slow-release carbon source is added in ecological filter cage, ecological floating bed is arranged in the upstream river reach of ecological filter cage in three-surface riverway, plant gabion is arranged in the downstream river reach of cascade dam body in three-surface riverway.Affirmative effect is: ecological floating bed, ecological filter cage, cascade dam body, plant gabion are set along the direction of water flow in three-surface riverway, slow-release carbon source is added in ecological filter cage, by multistage purification process, to carry out water quality restoration to three-surface riverway water body, strengthen the removal of pollutants in water body, i.
