| 摘 要： | 为更好地处理难降解的高浓度有机废水,研究了在间歇式超临界水反应装置内,超临界水氧化技术处理吐氏酸生产废水的最佳条件及其处理效果.通过单因素试验和正交试验,系统地研究了不同条件下废水COD和色度的去除率.当温度为380℃、压力为24 MPa、时间为150 s以及过氧比为1.8倍时,COD去除率可达96.7%,色度去除率可达97.5%,且反应后废水的可生化性有极大改善.

| Abstract: | In order to better treat high-concentration refractory organic wastewater,the optimum conditions and treatment effect for treating wastewater from Tobias acid production were studied in a batch-type supercritical water oxidation(SCWO) device by SCWO technology.Through single factor and orthogonal tests,the removal rates of COD and chrominance were investigated under different experimental conditions.When the temperature is 380 ℃,the pressure is 24 MPa,the residence time is 150s and the excess oxygen rate is 1.8,the removal rates of COD and chrominance reaches 96.7% and 97.5%,respectively,and the biodegradability of the wastewater is improved greatly. |
