lt to meet the discharge standard by traditional biochemical processes such as activatedРsludge process.In this study，three-dimensional electrolytic coupling photocatalytic technology is used to treatРРaniline wastewater，it mainly includes the preparation of activated carbon supported Zn modified TiO2 particleРelectrode by sol-gel method，and the crystal structure，surface and electrochemical properties of XRD electrodeРare characterized by XRD，SEM，BET and FTIR.The results showed that the TOC removal rate of aniline waste-Рwater reached 81.2% after 120 minutes under the conditions of raw water TOC concentration of 10 400 mg / L，РpH value of 5，zinc doping amount of 0.4% and aniline wastewater dilution of 4 times.РKey words：aniline wastewater，UV catalysis，three-dimensional electrolysis
