摘　　要：济钢1~#1 750 m^3高炉采取改善现有原燃料管理、完善炉况管理机制、合理优化现有技术、降低生铁含硅等措施,实现稳定高效低耗生产,高炉利用系数由2015年2.4 t/(m^3·d)提高到2016年的2.855 t/(m^3·d),燃料比由2015年的540 kg/t降低到2016年的520 kg/t。The pre-positive de-nitrification （A/O） process was used to treat coking wastewater in Taishan Steel Coking Company, and Fenton oxidation process was carried out after the biochemical treatment. After transformation for the coking wastewater treatment process, the removal of ammonia nitrogen effect is better. The effluent COD and ammonia can meet the indirect discharge standards. The effluent water quality indicators CODer is reduced to less than 150 mg/L, ammonia nitrogen is reduced to less than 25mg/L. The aerobic pool alkali quantity and operating costs are reduced.
