Wet air Oxidation(WAO) of wastewater from tricylazole production was studied. Experimental results Showed that WAO process is effective for treatment of the toxic organic wastewater. The highest removal in COD reached 80 percent. In studied range,the optimum process parameters were found by orthognal collocation method as 250℃, 8Mpa total pressure (21%O2) 2.5 hours,and feed PH7. 0. Cu(NO3)2,and CuO exhibited high catalytic activity.
