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。

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.
