Abstract：In this paper,coal fly ash was used as raw material to synthesize zeolite loaded with copper oxide for treatment of active red X-3B wastewater.The effects of ratio of ash to alkali,calcination temperature,crystallization time and ratio of ash to water on the COD and color indexes at the outlet of the treated wastewater were investigated by orthogonal test method.The optimal technical conditions of zeolite preparation were determined to be:ratio of ash/alkali 1.2:1,calcination temperature 600 ℃,crystallization time 6 h and ratio of ash/water 1:11.The prepared zeolite loaded with copper oxide was used to treat the active red x-3B wastewater with hydrogen peroxide,as an oxidant,to make the COD and color values in the wastewater be dropped from 450 mg·L-1 and 10 240 diluted times to 90 mg·L-1 and 3 diluted times with their corresponding COD and color removal rates of 80.02% and 99.97%,respectively.
