Abstract: Coking wastewater is a kind of toxic industrial wastewater containing a lot of COD organics, ammonia nitrogen, phenol and cyanide, which is difficult for degradation. To satisfy the more and more strict emission criterion, treating coking wastewater in an economical, effective and satisfactory way is of great significance. This article focuses on the research progress of degrading coke wastewater by Fenton oxidative method. Its principle, influence factors and application are discussed in this paper. It is expected to provide reference for the application of Fenton oxidation technology in coking wastewater treatment.

Key words: Coking wastewater, Fenton oxidation, Cyanide, Research progress
