| titleOfInvention | A double-layer constructed wetland for denitrification and phosphorus removal |
| abstract | The utility model discloses a double-layer constructed wetland for denitrification and phosphorus removal, comprising a water inlet pipeline, a dissolved gas device, a spraying device, an upper layer wetland pool and a lower layer wetland pool; wherein, the upper layer wetland pool includes a first layer of wetland pools from top to bottom. The plant layer, the first gravel layer and the second gravel layer, the first gravel layer and between the second gravel layer are provided with a phosphorus removal filler and a nitrifying filler with nitrifying bacteria solidified inside; the lower wetland pool is from top to bottom The bottom layer includes a second plant layer, a third gravel layer and a fourth gravel layer in sequence, and a solid carbon source filler with denitrifying bacteria solidified inside is arranged between the third gravel layer and the fourth gravel layer. The utility model has the advantages of low cost, high load, small footprint, multi-layer filtration and purification of sewage, and good effect of phosphorus and nitrogen removal. |
