SMBS is commonly used in the desalination industry as a dechlorination chemical prior to the membranes and also as an oxygen scavenger.
If your issue with the wastewater is solely the residual concentration of SMBS - perhaps you can try to introduce air aeration and the oxygen would react with the SBS formed from the hydrolysis of SMBS.
If you desire quick reaction, then sodium hypochlorite would be another choice that would give a much faster reaction.
Hope this helps.

Use an ORP to keep the charge at 0-20 mA and this is breakpoint area especially if you are going into secondary biological immediately. If so consider the benefits over feeding hydrogen peroxide for O2 in you mixed liquor. Sean
If you can give us your email, we can share our technology which can treat Sodium MetabiSulfite. We have experience in offering Wastewater solutions for almost all types of industrial wastewater.
Good day Sir, the best method of treating Sodium Methabisulfite you can use UV by temperature of below 25 and don't make water boiled just warm. That is the best way to reduce it.
Maybe you can try industrial symbiosis. Do you have and chromium production industry in your near location? SMBS is using for chromium removal from wastewater. Link
Your wastewater maybe useful for other wastewater treatment.
As for SMBS production: BASF is one of the largest producer of food grade product. Used as an oxidative disinfection agent mostly in wine production but also in foor processing, like prickles production and also in sea food. Multiple 1000 tons are produced per annume. There are plenty of local producers as well.
No, I didn't try with Lime. I Always have some problems with Lime, because it's necessary to correct the pH after that and not to mention the huge amount of sludge that it's generated.
