Multi-Stage Biochemical+Ozone Process Treatment System and Its Application
北方某钢铁厂污水处理系统设计规模为5.8 万t/d,主要处理钢铁工业膜系统浓盐水和脱氮废水,主体工艺采用多级生化+臭氧工艺.本文介绍了其各工艺单元的主要设计参数,并分析了2024年10月至2025年9月的运行效果.分析结果表明,该系统出水化学需氧量(CODCr)、氨氮、总磷平均值分别为23.5 mg/L、0.66 mg/L、0.09 mg/L,达到《地表水环境质量标准》(GB 3838-2002)中地表水Ⅴ类标准;出水总氮平均值为10.4 mg/L,满足《钢铁工业水污染物排放标准》(GB 13456-2012)要求.
The wastewater treatment system of a steel plant in northern China has a designed scale of 58,000 t/d,mainly treating membrane system brine and denitrification wastewater from the iron and steel industry.The main process adopts a multi-stage biochemical+ozone process.This ar-ticle introduces the main design parameters of each process unit and analyzes the operational perfor-mance from October 2024 to September 2025.The analysis results show that the average effluent val-ues of chemical oxygen demand(COD<sub>Cr</sub>),ammonia nitrogen,and total phosphorus are 23.5 mg/L,0.66 mg/L,and 0.09 mg/L,respectively,meeting the Class Ⅴ surface water quality standard of the"Environmental Quality Standards for Surface Water,GB 3838-2002".The average effluent total nitrogen value is 10.4 mg/L,meeting the requirements of the"Discharge Standard of Water Pollutants for Iron and Steel Industry,GB 13456-2012".
