Dear Ali,
Your water is highly concentrated in organic matter with a good biodegradability (BOD/COD ratio= 0,66) and probably with a temperature around 30° C.
One UASB reactor with biogas recovery followed by aerobic reactor can solve your problem with a relatively low operational cost.
You need to know pH, TSS, P, N and the flow pattern of your wastewater (is yeast batch production?) to decide for pre-treatment and your discharge limits for final treatment.
One well dimensioned UASB can reach COD 500-1000 mg/l in the outlet and the following aerobic reactor can reach less than 150 mg/l COD.
