LK-BAF 改良多级曝气生物滤池技术

      LK-BAF 改良多级曝气生物滤池技术主要用于石油化工、煤化工行业污水深度处理单元或二级生化单元，替代传统反硝化滤池、曝气生物滤池或MBBR工艺。污水经预处理、LK-LDB高效低氧生化技术处理污水后直接进入LK-BAF或经高效沉淀池或高效气浮+臭氧催化氧化处理后进入LK-BAF，出水直接外排或回用。对于排放要求较高（CODcr≤30mg/L）的难降解污水后端接尾水净化技术（UT30）、加炭高密池或活性炭吸附再生工艺。

      Modified Multi-Stage Aerated Biological Filter Technology (LK-BAF) is primarily used in advanced wastewater treatment units or secondary biological treatment units within the petrochemical and coal chemical industries, serving as a replacement for traditional denitrification filters, aerated biological filters, or MBBR processes. Wastewater enters LK-BAF directly after undergoing pretreatment and after the wastewater is treated with LK-LDB Low-Oxygen Biological Treats with high levels of organics, or alternatively after treatment through high-efficiency sedimentation tanks or high-efficiency air flotation coupled with ozone catalytic oxidation. The effluent is then discharged directly or reclaimed for reuse. For refractory wastewater with stringent discharge requirements (CODcr ≤ 30 mg/L), subsequent treatment processes such asTail Water Purification Technology (UT30), carbon-enhanced high-density sedimentation tanks, or activated carbon adsorption regeneration processes are implemented.

      该技术在传统BAF工艺基础上改良优化而成，主要对填料类型、布气方法等进行了改进。

      This technology is an improved and optimized version of the traditional BAF process, primarily featuring enhancements in media type and aeration methods.
