• 摘要：四溴双酚A（TBBPA）是一种使用广泛的阻燃剂，其扩散到环境介质中，会对生态和人体健康构成威胁，以往研究较少关注TBBPA在脱氮除磷工艺中的迁移转化.采用实验室SBR脱氮除磷反应器，研究了TBBPA在工艺长期运行过程中的去除、在典型周期过程中的变化、在硝化和反硝化过程中的去除.TBBPA在工艺长期运行过程中的去除率为48.4%，其中生物去除率为44.4%，吸附去除率为4.0%.在典型周期中TBBPA浓度受pH影响很大.TBBPA在硝化过程的去除主要是生物作用，而在反硝化过程的去除主要是吸附作用.

• Abstract：Tetrabromobisphenol A (TBBPA) is a flame retardant, and threats the ecology and human's health after releasing into the environment. Few studies have been focused on the transformation of tetrabromobisphenol A in biological nitrogen and phosphorus removal processes. By using sequencing batch reactors (SBRs) where biological nitrogen and phosphorus removal was achieved, TBBPA transformation was examined in long-term operation, typical SBR operation cycles, and nitrification and denitrification processes. The long-term experiment showed that the removal percentage of TBBPA was 48.4%, with the biological process contributing to 44.4% and adsorption contributing to 4.0%. Concentration of TBBPA in a typical cycle was highly affected by pH. Removal of TBBPA during nitrification was mainly due to the biological process, while removal of TBBPA during denitrification was mainly due to adsorption.
