How to treat COD and ammonia nitrogen in wastewater from alkaline desulfurization of catalytically regenerated flue gas
Thread Content
Experts: How can COD and ammonia nitrogen in the alkaline flue gas desulfurization wastewater from catalytic regeneration be treated separately, and what process routes should be employed? Are there any successful cases?
Is there any expert who can answer? Same request
What are the acceptable levels for COD and ammonia nitrogen? Are there any other substances?
COD is oxygenated using a jet pump; as for ammonia nitrogen, denitration has been carried out earlier, so it should meet the standards
What process do you use – does it involve oxygenation with a jet pump to remove COD?
Removing COD relies mainly on enhancing the mass transfer process (gas-liquid contact) to improve oxygen utilization. At present, there seems to be no very effective method for dealing with NH3-N; steam stripping is used to address this issue, but I suggest it is better to solve the problem at its source.
