| titleOfInvention | Photocatalytic simultaneous removal of nitrite and ammonia nitrogen from sewage |
| abstract | The invention discloses a photocatalytic simultaneous removal method of nitrite and ammonia nitrogen in sewage. The removal method comprises: adding copper bismuthate-graphene oxide/aza-graphene photocatalyst to the sewage containing nitrite and ammonia nitrogen, feeding nitrogen, and then irradiating the obtained mixed system with ultraviolet and visible light, thereby simultaneously The nitrite and ammonia nitrogen are removed; after that, air is introduced, and the mixed system is continuously irradiated with ultraviolet and visible light to achieve complete denitrification. The copper bismuthate-graphene oxide/azagraphene photocatalyst includes a copper bismuthate-graphene oxide composite semiconductor material and/or a copper bismuthate-azagraphene composite semiconductor material. The invention creatively integrates nitrite removal and ammonia nitrogen removal, simultaneously removes nitrite and ammonia nitrogen under the irradiation of sunlight, changes the traditional technological process of nitrogen removal and nitrite removal, and shortens the The working time is reduced, the time cost is reduced, the economic cost is saved, and the removal rate is high. |
