Abstract: |
Under the surface plants several percolating channels and water-distributing grooves are set, the interior of percolating channel is filled with artifically-made speciall soil, and at two sides of water-distributing groove the reinforced water-distributing material can be set, under the action of comprhensive cleaning function of soil, microorganism and plant system, the sewage can be cleaned, the cleaned water can be collected by a water-collecting channel set on the impervious layer of its bottom portion, and discharged out by a water-collecting tube. Said invention can make removing rate of COD, amino nitrogen, total nitrogen and total phosphorus being in domestic sewage by up to above 90%. |
