Beschreibung
Zusammenfassung:	The invention relates to a marsh gas oxygen-enriched combustion-biogas slurry denitrification system and method, and belongs to the technical field of marsh gas flue gas denitrification. According tothe marsh gas oxygen-enriched combustion-biogas slurry denitrification method, marsh gas oxygen-enriched combustion is performed to obtain a high combustion value, combustion flue gas is generated, nitric oxides in the combustion flue gas mainly include NO and NO2, NO of the combustion flue gas is dissolved in micro-alkaline biogas slurry in countercurrent contact to react with oxygen dissolved into the biogas slurry, some NO is further converted into NO2, and micro-alkaline biogas slurry drops absorb NO2 and NO and other gas in the flue gas under countercurrent contact to generate inorganic acid radical ions. According to the marsh gas oxygen-enriched combustion-biogas slurry denitrification system and method, the process technology is simple, operation is easy, the cost is low, the denitrification rate is high,
