| 摘 要： | 实验研究了垃圾渗滤液在超临界水中的氧化降解。结果表明，超临界水氧~（scwo）技术能有效地降解垃圾渗滤液（coDcrl555-7585mg／L、TOC947．5～1788mg／L、TNl834～4166mg／L），在24MPa、390℃～440℃、停留时间16，3s～36．0s的条件下，其CODCr、TOC和TN的去除率可分别达到90．7％、68．1％和57．9％，可生化性有所提高．而且脱色除臭效果良好。 |

| Abstract: | The oxidated decomposition of landfill leachate in supercritical water （SCW） was studied. The results showed that organic pollutants in landfill lcachate （CODc, 1555～7585 mg/L,TOC 947.5～1788 mg/L,TN 1834 ,～4166 mg/L） could be decomposed effectively by supercritical water oxidation （SCWO）. Under SCWO conditions, the removal rates of CODc, , TOC and TN of landfill leachate could reach 90.7%, 68.1% and 57.9%, respectively,its biodegradability could l？e raised and its color and fetor were got rid of effectively at a pressure of 24 MPa, temperature of 390 °C～440 °C, and reactor residence time of 16.3～36.0 s. |
