Abstract

Abstract

As a kind of hazardous solid waste, oily scum does not only pose a huge threat to the ecosystem, but also cause of non-renewable resources. Aiming at the problems of high oil content, high organic matter of oily scum, based on the modification of oil content residue phase and TOC removal rate in water phase, the conditions of ultrasonic-Fenton oxidation process assisted by demulsifier were optimized by single factor experiment. The results showed that the optimal conditions were as follows:the concentration of SP-142 was 20 mg/L, ultrasonic time was 10 min, solid-to-liquid ratio was 1:4, temperature was 60℃, pH value was 3, the concentration of Fe²⁺ was 0.4 g/L, and the dosage of H₂O₂ was 2 mL. As a result, the oil content in the residue phase was 20.65%, and the removal rate of TOC in water phase was 45.98%, which provided a reference for the resource utilization of oily scum.
