  • 摘要:作为开发强化去除典型溴代阻燃剂四溴双酚A的重要一环,研究了厌氧微生物与Fe-Ni双金属材料联合对四溴双酚A的去除.结果显示:首先,联合体系较单独的厌氧微生物及单独的Fe-Ni双金属材料去除四溴双酚A有更高的去除率,6 h去除率可达到75.50%;联合体系四溴双酚A去除过程符合一级动力学模型,速率常数k为2.2917 h-1,半衰期为0.31 h.其次,利用基于BOX-Behnken(BBD)设计的响应面分析法(RSM)来寻找联合体系四溴双酚A的最佳去除条件,在初始接菌量为0.8,温度为29℃,TBBPA初始浓度为5 mg·L-1时,四溴双酚A的去除率最大.最后,受环境干扰情况的实验结果表明,自然水体条件或添加腐殖酸干扰情况下,均会造成联合体系对四溴双酚A去除率一定程度的降低.
  • Abstract:In view of the contamination of Tetrabromobisphenol A in environment, a novel integration of enriched TBBPA-degrading anaerobic microbles and Fe-Ni bimetallic particles was applied to remove TBBPA. A higher removal rate of Tetrabromobisphenol A was investigated in integration system compared to those using single anaerobic microorganism and Fe-Ni bimetallic simply. The degradation date fitted first-order kinetic model well with, the rate constant k of 2.2917 h-1, half-life of 0.31 h. A response surface methodology based on the BOX-Behnken design was applied to determine the optimum conditions. Under the optimal condition (an inoculum of 108 cell, a temperature of 29℃, and an initial concentration of TBBPA of 5 mg·L-1), the removal rate of Tetrabromobisphenol A reached 75.50% within 6 h. It's worth to point that TBBPA also can be reduced using synergistic integration of anaerobic microbes and Fe-Ni bimetallic particles even in natural water or the system containing of humic acid.
