Dear Muna,
if you have enough space, consider the possibility to use constructed wetlands. The are very cheap in O&M costs, and they have shown high removal efficiencies for typical pollutants (e.g. 77-98% BOD; 65-98% COD) as shown in Vymazal (2014).

wetlands are good for polishing and nutrient removal. but is not effective with high strength waste treatment. cheers

Without a DAF, the wetlands will block and become anaerobic, which will at best inhibit the reeds and at worst could kill them. Even then it will depend on the BOD coming from the DAF, because they may still fail without further BOD strength reduction.
