曝气生物滤池反冲洗特性的研究

曝气生物滤池集生物膜的强氧化降解能力和滤料截留效能于一体，是一种适合大规模回用、高效、低耗的污水再生工艺，也是升级改造的良好选择。反冲洗是曝气生物滤池运行中的一个关键步骤，合理优化反冲洗过程有助于改善其整体运行性能。根据反冲洗废水浊度变化确立了合理的反冲洗方式，并给出相关的反冲洗强度和反冲洗历时参数，以期为曝气生物滤池处理印染废水的设计和运行提供参考。

Study on Backwash Properties of Biological Aerated Filter

Biological aerated filter set of biofilm-degradability and media interception performance in one,is a sewage reclamation technology which is suitable for large -scale reuse,efficient,low consumption and easy to upgrading.Backwashing process is a critical step in the operation of biological aerated filter.Optimization of backwashing process is favorable to the improvement of operation perform.Based on the turbidity variation in backwash effluent,the proper backwash method was determined and the related parameters such as backwash strength and period were recommended,so as to offer reference for the design and operation of biological activated filter to treat dyeing and printing wastewater.
