| titleOfInvention | Wastewater treatment device for enhancing biological nitrogen and phosphorus removal |
| abstract | The utility model discloses a wastewater treatment device for strengthening biological nitrogen and phosphorus removal, which is characterized in that the inner part of a reactor shell is divided into a first reactor area and a second reactor area, the outlet end of the first reactor area is provided with an overflow baffle, and the inlet of the second reactor area is positioned at the bottom and is positioned at the downstream of the overflow baffle; a water inlet, a cobblestone supporting layer, a Qing stone layer, a pyrite layer and a sludge mixing zone are sequentially arranged in a first zone of the reactor from bottom to top; a sulfur layer is arranged in the second zone of the reactor. The Qing stone layer provides an inorganic carbon source (carbonate) and calcium ions to provide a substrate for removing phosphate radical, meanwhile, the carbonate radical can play a role in buffering pH adjustment, and the pyrite provides iron ions with different valence states and sulfur ions with low valence states to provide a substrate for removing nitrate radical and total phosphorus. |
