| 摘 要： | 用H2O2作为氧化剂,在595～704 K、18～30 MPa条件下,对活性染料废水进行超临界水氧化反应.实验结果表明,COD去除率随温度、压力、停留时间和氧化剂量的增加而上升,在704 K、28 MPa时,COD去除率可达到98.4%,停留时间小于35 s.COD、H2O2和水的反应级数分别为1、0和0;反应活化能Ea为37.21 kJ/mol;指前因子A为76.69 s-1.

| Abstract: | Using H2O2 as the oxidant, a reactive dyeing wastewater was oxidized in supercritical water at 595~704 K, 18~30 MPa. The results showed that COD removal efficiency increased with the increasing temperature, pressure, oxidant dosage, and residence time. 98.4% of COD removal efficiency was achieved at 704 K, 28 MPa with a residence time of <35 s. The oxidation was 1, 0 and 0 order for COD, H2O2 and water, respectively. The activation energy Ea was 37.21 kJ/mol, and pre-exponential factor A was 76.69 s-1. |
