| titleOfInvention | A method and reactor for simultaneous nitrification-autotrophic denitrification and denitrification of high-nitrogen wastewater based on multi-source electron donors |
| abstract | The invention discloses a method and a reactor for simultaneous nitrification-autotrophic denitrification and denitrification of high-nitrogen wastewater based on multi-source electron donors. The denitrification method of the present invention comprises: adding sodium thiosulfate to the high-nitrogen wastewater and successively entering a three-stage synchronous nitrification-autotrophic denitrification reactor, wherein siderite (FeCO 3 ) and pyrite are suspended in the reactor. The composite filler composed of (FeS 2 ) and iron shavings (Fe 0 ) undergoes simultaneous nitrification-autotrophic denitrification under the condition of aeration and oxygenation, so that the total nitrogen in the wastewater can be efficiently removed, and the treated water enters the sedimentation tank for sedimentation after discharge. Compared with the traditional nitrification and denitrification (AO) denitrification, the method and the reactor of the present invention based on the multi-source electron donor synchronous nitrification-autotrophic denitrification denitrification method for high nitrogen wastewater do not need external organic carbon sources and nitrification solution. Reflow, the operating cost is greatly reduced. |
