| titleOfInvention | Method and system for advanced treatment of nitrate and nitrite mixed wastewater |
| abstract | The invention discloses a method and a system for advanced treatment of mixed wastewater of nitrate and nitrite, belonging to the field of advanced treatment and recycling of wastewater. The method comprises the following steps: the mixed wastewater passes through a shallow sand filter to remove suspended particles in the water; enabling the filtrate to flow into an oxidation reaction tank, and adding a hydrogen peroxide solution to oxidize nitrite in the filtrate into nitrate; (the filtrate in the oxidation pond flows into a pH regulating pond to regulate the pH value to 6-6.5; the filtrate passes through an adsorption tower filled with a polymer adsorption material YNA-201; (E) the adsorption is stopped when the adsorption reaches a penetration point, and the adsorption material YNA-201 is washed and desorbed by a desorption agent) 2 ‑ Complete removal of-N, NO 3 ‑ the-N is stably reduced to below 10 mg/L. |
