Abstract Reclamation of mixed treated wastewater discharged from iron and steel enterprises is an effective way to reduce water consumption. The Wai River of the Baosteel is rich of treated wastewater, but its high iron and manganese concentration limits its application in reuse. Constructed wetland with manganese ore media was studied in the reclamation of the steel wastewater. The results showed that Fe, Mn could be removed effectively. The effluent could meet to “The reuse of urban recycling water-Water quality standard for industrial uses”（GB/T 19923-2005）and quality requirements of Baosteel process water. Manganese ore wetland performed stably showing litter dependence on HRT, season alternation, temperature, and etc. The operation cost was lower than the cost of city water, indicating significant economic benefits.
