description The invention provides a Fenton-like technique for treating biochemical effluent. According to the technique, the pH value of the biochemical effluent to be treated is controlled at 6.0-7.0, and Fenton-like reaction is performed under the combined actions of a ferrous salt solution and oxydol by using a supported nano iron oxide catalyst with the particle size of 10-40 meshes. The Fenton-like technique is especially suitable for carrying out advanced treatment on biochemical effluent in the field of coking, can obviously enhance the catalytic efficiency of the Fenton-like reaction process, avoids the side reactions, avoids generating float sludge in the treatment process, and enhances the quality of the treated effluent. Besides, the pH value of the treated effluent is 7.0-8.0, and the treated effluent can be directly discharged without regulating the pH value. Besides, the sludge generated in the reaction process can be subjected to waste utilization for paint production. The invention also provides a reacto
