Reclaimed water treatment system combining upflow aerating biological filter with horizontal underflow artificial wetland

The invention discloses a reclaimed water treatment system combining an upflow aerating biological filter with horizontal underflow artificial wetland. The system consists of the upflow aerating biological filter and the horizontal underflow artificial wetland; the upflow aerating biological filter comprises a water inlet guide tube positioned at the bottom of the filter; a filter plate, a supporting layer, an A section filler area, a B section filler area and a water outlet area are sequentially arranged above the water inlet guide pipe; a communicating water pipe is mounted on the water outlet area, and communicated with a regulating tank of the horizontal underflow artificial wetland; an aerator pipe is led out of the supporting layer; the regulating tank and a matrix area parallel to the regulating tank are arranged at the lower layer of the horizontal underflow artificial wetland; the matrix area sequentially comprises a macadam area, a steel slag area, a zeolite area and a water outlet gravel area from left to right; the water outlet gravel area is equipped with a water outlet pipe; and a soil covering layer and aquatic plants are arranged at the upper layer of the horizontal underflow artificial wetland. With the adoption of the system, on-site treatment and utilization of sewage are achieved; the sewage treatment process flow is simplified; and operation and management costs are lowered.
