Normally such a high COD waste is treated anaerobically producing Methane (biogas) which can be recovered and burnt or flared.
The problem with Sulfinol/Amine waste is it is mostly Ammonical waste and can not be degraded anerobically as such the best method to deal with this waste will be wet air oxidation (WAO). In cast there are Nitrate limitation for discharge water then the WAO effluent need to be denitrified and aerated before disposal.

The answer to your question depends on the volume of the waste. For this high value of COD we have found a solution via a mini-biodegradation unit. The company Biosoil in the Netherlands can help you solve your problem. See link http://www.biosoil.nl/site/biosoil/index.html?LC=en .

This is too high a COD and difficult one to treat. Ideally. Amine wastes are recycled within Amine plant and should not be discharge to waste water system.
If you are unable to do so, you can look into possibility of incinerating the waste.
