克拉玛依石化工业园污水处理厂曝气生物滤池工艺除磷效果分析

Analysis on the Effect ofDephosphorization by Biological Aerated Filter Process in Sewage Treatment Plant of Karamay Petrochemical Industrial Park

摘要: 克拉玛依石化工业园污水处理厂采用气浮、S3D加三级生物滤池工艺，处理后的出水要求达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A的标准，即处理后的总磷要求达到0.5 mg/L以下。结合污水处理厂的实际工艺，重点研究了系统的化学除磷和生化混合除磷，对以后类似的工艺运行具有参考意义。

Abstract: The sewage treatment plant of Karamay petrochemical industrial park uses flotation, S3D and three-stage biological aerated filter process; the treated water has reached level A standard of the “Urban Sewage Treatment Plant Pollutant Discharge Standard” (GB18918-2002), meaning that the total phosphorus after treatment are less than 0.5 mg/L. Combined with actual process of the se-wage treatment plant, this paper focuses on chemical dephosphorization system and biochemical mixed dephosphorization, having reference significance to the later similar process.
