摘要：

Phenolic wastewater is a typical kind of industrial effluents with high toxicity and poor biodegradability. Huge quantities of phenol-polluted waters are formed from many chemical operations including coking, coal gasification, oil refineries, plastics, pesticides, steel and phenolic resin production. This paper deals with treating high phenol-concentrated wastewater by supercritical water oxidation (SCWO) method. The effects of H2O2 dosage, reaction time, temperature, and concentration of glycol on removal efficiency of phenol were studied with laboratory bench-scale experiments. The results indicated that the removal process was more effective under the experimental conditions. The best removal efficiency of phenol reached 99.8%. This investigation could provide fundamental method for developing a pretreatment method of industrial phenolic wastewater with flexibility, simplicity and high activity.
