摘要：

The effluent of Tufftride Process, a soft nitriding process for iron-related material, contains concentrated iron cyanide complex. Due to the nature of the effluent, a treatment process employing conventional technology may become a complex one, For this reason, a simple advanced system with new technology has been hoped for. Since 1991, Water Reuse Promotion Center (WRPC), collaborating with Osaka Gas Co., Ltd. (OGC) and Nihon Parkerizing Co., Ltd (NPC), has been working to develop a new process for treating concentrated cyanide wastewater using OGC catalytic wet oxidation (CWO) process. Through the operation at NPC Sendai plant, it has been confirmed that the process is technically feasible and economically acceptable.
