Abstract: | Ferrous chelate absorption is deemed a promising method for NO removal from flue gas, but the key problem is the difficulty to regenerate the absorption solution, i.e. the complexes of FeⅡ(EDTA)NO and FeⅢ(EDTA) in the solution. Two bacterial strains isolated recently from the sludge of the denitrification step of a municipal wastewater treatment plant could be applied effectively to regenerate the absorbent were Pseudomonas sp. and klebsiella trevisan sp. Pseudomonas sp. exhibited high reduction ability on FeⅡ(EDTA)NO and the klebsiella trevisan sp. was more suitable for FeⅢ(EDTA) reduction. |
