| titleOfInvention | One-step denitrification device based on iron salt circulation |
| abstract | The utility model discloses a one-step denitrification device based on iron salt circulation, wherein a first reaction chamber is arranged above a second reaction chamber and is connected with the second reaction chamber through a water inlet pipe, and the first reaction chamber is used for nitration reaction to generate nitrous oxide and ferric iron; the nitration reaction liquid enters a second reaction chamber from a first reaction chamber; the second reaction chamber is used for autotrophic denitrification reaction, and nitrate and ferrous iron from the first reaction chamber react to generate nitrogen and ferric iron so as to realize denitrification; the water outlet end of the second reaction chamber is provided with a reverse osmosis membrane for intercepting iron ions, the second reaction chamber is provided with a return pipe interface, and the concentrated ferric iron solution is returned to the first reaction chamber for recycling. The utility model provides different living environments for growth and metabolism by separating nitrobacteria and denitrifying bacteria in two reaction chambers; the ferric iron concentrated solution generated by the second reaction chamber flows back to the first reaction chamber, and the wastewater is denitrified by recycling the ferric salt in one step, so that the method has innovation consciousness and practical value. |
