摘　　要：实验研究了葡萄糖在超临界水中的氧化降解。结果表明 ,超临界水氧化技术能有效地降解废水中的葡萄糖 ,COD去除率可达 98%。随着反应温度的升高、压力的增大、停留时间的延长和初始废水浓度的增大 ,COD去除率也随之提高。葡萄糖在超临界水中氧化降解的动力学方程为- d[COD]dτ =2 4.2 exp - 3.0× 10 4RT [COD]1.0 3 [O2 ]0 .0The oxidated decomposition of glucose a typical organic pollutant in supercritical water (SCW) was studied in this paper. The results showed that organic pollutant can be decomposed effectively by supercritical water oxidation (SCWO). The COD removal rate increased with increasing temperature, pressure, residence time and concentration of wastewater. The maximum of COD removal rate reached 98%. The oxidated decomposition dynamic equation of glucose in SCW was established as follows: -d[COD]/dτ = 24.2exp(-3.0 × 104/RT)[COD]1.03] [O2]00.067.
