Abstract—Oxidation of fabric dyeing wastewater was investigated objects, and now it has been developed at the pilot and
in supercritical water with CuSO4/FeSO4 as catalyst. The effects industrial scale to treat industrial wastewater [6].
of various operating parameters like temperature, pressure,
hydrogen peroxide concentration and catalyst concentration on The addition of catalyst can increase the yields of the
the removal of color and COD from wastewater plete oxidation products and decrease the process
investigated. The percent removals of color and COD at 450℃, temperature and pressure required during SCWO process. Lots
28MPa using 120% hydrogen peroxide dosage and of published papers had reported on the effects of mainly
catalyst was 100% and 99%, respectively. Experimental results transition metals, on SCWO pounds, because
indicated that CuSO4 and FeSO4 had a significant effect on the transition metal salts monly used as homogeneous
COD and color removal. CuSO4 had greater effect on COD and catalysts in normal liquid phase autoxidation [7].
