Abstract
This invention discloses an ecological environment restoration water treatment device based on biological filler material, relating to the field of wastewater treatment technology. It includes a stirring mechanism, a sedimentation mechanism on the right side of the stirring mechanism, a first biological filler material treatment unit below the right side of the sedimentation mechanism, a second biological filler material treatment unit below the first biological filler material treatment unit, a one-way valve on the discharge pipe of the second biological filler material treatment unit near the anaerobic treatment tank, an anaerobic treatment tank below the second biological filler material treatment unit, and an aerobic treatment tank below the right side of the anaerobic treatment tank. This invention uses the stirring mechanism to uniformly treat wastewater sludge, and after sedimentation treatment by the sedimentation mechanism, the wastewater sludge is fed to the first biological filler material treatment unit. The first and second biological filler material treatment units purify the wastewater.
