With the rapid development of industrial technology in China, the output of industrial wastewater is also increasing day by day, in which coking wastewater discharge is large, composition is complex, influence degree is deep, the environmental pollution caused by it is especially prominent, a series of discharge standards are becoming more and more strict, and the treatment of coking wastewater is imminent. In order to realize the policy requirement of "zero discharge" of enterprise wastewater as soon as possible, various new treatment technologies emerge as the times require, and the treatment effect and application scope are obviously improved. In this paper, the characteristics and limitations of the existing coking wastewater treatment technology are reviewed. At present, the coking wastewater treatment methods are mostly focused on biological treatment technology and advanced oxidation method, but there are still some problems and challenges in the actual operation of the two commonly used technologies, such as poor treatment effect and high operating cost. However, the technology of biodegradation and advanced oxidation coupling treatment has a broad prospect, which not only improves the treatment efficiency, but also opens up the field of multi-dimensional exploration. A large number of studies have shown that it has great feasibility for the treatment of refractory and polluted wastewater.
