超临界水氧化法处理苯胺废水

Oxidation of aniline in supercritical water

水样中苯胺的超临界水氧化 (SCWO)表明氧化剂过氧化氢的用量、试验温度、压力和停留时间对水中 TOC的去除率有显著影响。在 5 0 0℃、2 5 MPa和 K =1.1条件下 ,停留时间为 3 5 s,TOC去除率可达 99%以上。 TOC去除率随起始浓度的增加而提高。这表明 SCWO适于处理高

The oxidation of aniline in supercritical water indicated that the dosage of the oxidant H\-2O\-2, experiment temperature, pressure and reaction residence time have remarkable effect to the TOC removal. At a temperature of 500 ℃, pressure of 25 MPa, residence time of 35 s and \%K\%=1.1, TOC removal can achieve over 99%. TOC removal improves with the increases of initial concentration. The result suggests that SCWO is applicable to treat high TOC wastewater.\;
