摘要：
Oily wastewater is inevitable output of petroleum chemical industry, mainly from oil field produced water, the high salt content of the crude salt water to wash with water, flushing sewage. In this paper, supercritical water gasification was applied to treat the oily wastewater. The effect of reaction pressure, reaction time, temperature and oxidant dosage on the gasification of oily wastewater was investigated. The results indicated that the process was effective under the experimental conditions. High temperature favours the destruction of oily wastewater. It is shown that rising temperature and reaction pressure increased the total organic carbon (TOC) removal. The best TOC removal reached 98.9%.
