Iron-carbon substrate constructed wetland was used to carry out advanced treatment of coking water. Results showed that iron-carbon substrate constructed wetland had decent treatment results for the organic pollutants. When HRT was 3d, removal efficiency of COD and TOC was 20% and 35%, COD average was 44.25mg/L, which can meet the standard of circulating cooling water and make-up water in the standard of (GB/T 19923-2005). The iron-carbon substrate change the structure of organic pollutant and transform the macromolecular organic matter into small molecular organic matter, which improve the biodegradability of the wastewater and is conducive to the removal of organic matter in the follow-up wetland. Manganese sand substrate can remove the iron in the effluent of iron carbon zone, which makes the impact on the iron concentration from using iron-carbon substrate negligible. The wetland also has good removal effect for toxicity.
