Abstract：Theinfluentofatwonew industrialparksewage treatmentplantcontainsdificulttodegradechemicalpollutants， andtheexisting process cannotstablyachieveefuentdischarge standards.The technicalandeconomicfeasibilityof Fentonoxidation processand compositeozonecatalyticoxidation process iscompared through intermediate experiments，and the optimizationsolutions are proposed.Theresults showthatthe Chemical Oxygen Demand（COD）removalrateof Fenton oxidation process is 46%～71% ，the operating cost is 1.83 yuan/t of wastewater，and the comprehensive investment cost is 21.08 million yuan; the COD removal rate of the composite ozone catalytic oxidation process is 56%～ 71% ，the operating costis1.20yuan/tofwastewater，andthecomprehensiveinvestmentcostis18.82millonyuan.TheCODremovalefficiency of the compositeozonecatalyticoxidationprocess is superiortothatoftheFentonoxidation process，withloweroperating and comprehensive investmentcosts，andnosecondarypollution from sludge.It is recommended toadopt thecomposite ozonecatalyticoxidation processasadeep treatmentrenvation plan，providing reference forsewage treatmentin similar chemical industrial parks.
