摘　　要：Apilot scale test of advanced treatment of ethene wastewater by ozonization was carried out for industrial water reuse.Effects of different operating conditions on COD degradation,such as wastewater flow rate,ozonized gas flow rate,operating voltage of ozonizer and two ozone generation means,using pure oxygen or air,was investigated.The results show that the increase of ozonizer operating voltage,the decrease of wastewater flow rate and the suitable ozonized gas flowrate improve the removal ofCOD inwastewater and thatozone generatedrespectively fromair and pure oxygen can effectively remove COD of ethene wastewater to meet the industrial water reuse criterion.
