Process for the biological treatment of solid waste and mud contaminated by hydrocarbons

Process for the biological treatment of solid waste and mud contaminated by oily residues. A pre-treatment step at 40-110 DEG C by at least one extraction with a non-volatile organic solvent in a ratio 0.1-3 : 1 is performed to separate the oily phase from the solid residue. The emanating solid resi...

Zusammenfassung:Process for the biological treatment of solid waste and mud contaminated by oily residues. A pre-treatment step at 40-110 DEG C by at least one extraction with a non-volatile organic solvent in a ratio 0.1-3 : 1 is performed to separate the oily phase from the solid residue. The emanating solid residue is washed with a supernatant liquid resulting from a bioxidation of the washing medium.
