Description of Publication:Highly efficient dewatering is essential to the reduction and reclamation disposal of oily sludge (OS). How to effectively break the water/oil emulsion is a paramount challenge for dewatering of OS. In this work, a Fenton oxidation approach was adopted for the dewatering of oily sludge. The results show that the oxidizing free radicals originated from Fenton agent effectively tailored the native petroleum hydrocarbon compounds into smaller organic molecules, hence destructing the colloidal structure of OS and decreasing the viscosity as well. Meanwhile, the zeta potential of OS was increased, implying the decrease of repulsive electrostatic force to realize easy coalescence of water droplets. In addition, the quality of oil phase was upgraded after Fenton oxidation treatment accompanying with the degradation of native organic substances in OS, and the heating value of OS was increased from 8680 to 9260 KJ·kg-1, which would facilitate to the subsequent thermal conversion.
