The invention discloses a
sewage treatment system based on an AO-MBBR-
inductive coupling filter tank and a method thereof. The
treatment system comprises an anoxic tank, an aerobic tank, a
sedimentation tank, a constant-
voltage direct-current power supply and a one-stage or multi-stage
inductive coupling filter tank, the bottom of the anoxic tank is communicated with the bottom of the aerobic tank, the side wall of the top end of the aerobic tank is communicated with the
sedimentation tank, the side wall of the top end of the
sedimentation tank is communicated with the
inductive coupling filter tank, an
electrode matrix is arranged in the inductive
coupling filter tank, and the constant-
voltage direct-current power supply is electrically connected with the
electrode matrix. A second
aeration branch pipeline is arranged at the bottom of the inductive
coupling filter tank, a perforated baffle plate is horizontally arranged in the inductive
coupling filter tank close to the upper part of the second
aeration branch pipeline, and
aeration main pipes communicated with each other are arranged between the inductive coupling filter tank and the anoxic tank and between the inductive coupling filter tank and the aerobic tank. According to the invention, AO, MBBR and inductively coupled filter technologies are combined to treat pollutants in
sewage,
nitrogen,
phosphorus and organic matters in domestic
sewage can be efficiently removed at the same time, and finally, the
effluent can reach the standard
discharge.
