Wastewater Treatment Suggestion

I'm doing R&D work for one effluent. 

It has inlet parameters:

• 20000 mg/L COD,
• 7000 mg/L  BOD,
• 25000 mg/LTDS,
• NH3- N is 60 mg/L,
• more than 1000 hazen colour (dark yellow colour),
• 100 mg/L TSS basic contain is nitric acid and benzoic acid.

I want outlet parameters:

• pH around 7,
• 2000 mg/L COD,
• 25000 mg/L TDS.  

What kind of treatment do I have to use?  Please give me your important suggestions.
