Aiming at the caprolactam wastewater discharged from a chemical enterprise, the electrocatalytic oxidation technology was used for advanced treatment. When the current is 450A and the inflow flow is 3m 3 /h, the COD value of the effluent is reduced from 100mg/L to below 50mg/L, the ammonia nitrogen is reduced from 10mg/L to below 4mg/L, and the chroma is reduced from 50 times to below 30 times. The effluent quality meets the class A standard in Table 3 of 《Discharge standard of pollutants for municipal wastewater treatment plant》 (GB 18918-2002).
