When you say high sulfinol to discharge I presume it is few hundred ppm. If it is less % then you should try to recycle it by filtering it through Activated Carbon bed (removing all impurities).
If it is few hundred ppm the best way to treat it would be to mix it with other plant waste.This would provided it the dilution and most important other organic matter as supplement.
Sulfinol waste would be very high in Ammonical Nitrogen which can be oxidised to Nitrates (process called Nitrification) in a biological unit such as Activated Sludge subject to the ratio of 100:5:1 ( BOD:Nitrogen:) Phosphorus is maintained in the feed.
It is also possible to oxidise it to Nitrates without supplemental BOD in a bio reactor ( Nitrifier).
Bio treatment is best as this waste can neither be stripped nor adsorbed.
Chemical oxidation with H2O2 etc will be expensuive.
Without much information about quantity and concentration and availability of other waste to supplement this is the best suggestion. If all information is available a better solution can always be given.
