One kind of buried sewage treatment system Eco

The present invention belongs to the technical field of sewage treatment environmental engineering, and particularly to an apparatus for waste water treatment. The present invention employs the following technical solutions A buried sewage treatment ecological system, characterized by: a housing comprising a relatively closed, water distribution cabinets provided with a means macroporous highly air-permeable filter layer, layer anaerobic denitrification percolation layer, and water drainage gravel closed, wherein a macroporous highly air-permeable filter layer, anaerobic denitrification layer, infiltration layer and close sequentially from top to bottom aqueous layer of gravel laid in the housing, the housing macropores positioned at intervals of the filter layer or casing at a position corresponding to the high permeability is provided with an air inlet, said water distribution means disposed above the sprinkler head macroporous highly air-permeable filter layer, said drain input water is provided below the percolation layer. By using the above-described embodiment, the present invention provides a highly efficient oxygen-rich unpowered achieve new buried sewage treatment system Eco sufficient direct contact with water and air.
