高盐废水超临界水氧化处理过程的响应面优化
Optimization of supercritical water oxidation of high salinity wastewater using response surface methodology
摘要
Abstract
High salinity wastewater was generally characterized with high concentration of salt and organic contaminants. It became a difficult problem for industrial wastewater treatment. The process of supercritical water oxidation (SCWO) for high salinity wastewater treatment was optimized using response surface methodology (RSM) . The effects of temperature, pressure and reaction time on removal efficiency of total dissolved solids (TDS) were investigated. A quadratic polynomial mathematical model between TDS removal rate and various factors was established. It was concluded that the order of influence of each factor on TDS removal rate was pressure> temperature> reaction time. The TDS removal rate of wastewater reached 93.69％ under the conditions of temperature 480 ℃, pressure 22 MPa and reaction time 50 s.关键词
