Dear Pardeep Singh: to answer your question correctly it is necessary to know what are the pollutant (hydrocarbon) concentration in raw wastewater and what are the treatment limits for treated wastewater (what should be the final concentration of pollutants, COD, BOD, etc. in treated wastewater). According to these parameters you can choose an optimum treatment technique.

It would depend on the concentration of the pollutants and the desired treatment levels. Biological treatment is cheaper but may not be able to completely remove the pollutants. Photocatalysis can oxidize the organic pollutants completely but may be relatively more costly. Thus, if the there is high concentration of the pollutant and your objective is to reduce such concentration to some lower amount, then biological treatment may be more cost-effective. On the other hand, if the concentration is low and you want completely remove the pollutant, then photocatalysis may more cost-effective.
Its depend on the concentration of pollutants . Bio catalysis is cheaper but it may not treat all the chemical which exit in the pollutants . the photo-catalysis can be able to treat all organic compound inside the pollutants, but it may be cost-effective.
Its depend on the concentration of pollutants and treatment types
