中文摘要	利用新型高效的双极性脉冲放电等离子体水处理技术对常用有毒阻燃剂四溴双酚A(tetrabromobisphenol A,TBBPA)进行了降解试验。研究了在双极性脉冲放电不同条件包括放电电压、气体体积流量,填料球粒径,溶液电导率,TBBPA溶液初始质量浓度以及负载TiO2光催化剂等对TBBPA的降解效果。实验结果表明:双极性脉冲放电等离子体系对TBBPA有着良好的降解效果。放电电压越高,降解效果越好;在一定范围内,气量变小,降解效果更好;填料球粒径越小,降解效果越优;溶液电导率越小,TBBPA去除率越高;负载TiO2光催化剂能够明显提升放电等离子体对TBBPA的降解效果。在降解过程中,TBBPA被分解为小分子,并且存在脱溴环节。; Degradation of the flame retardants tetrabromobisphenol A(TBBPA) by bipolar pulsed discharge plasma water treatment technology was investigated. Degradation rate of TBBPA under different conditions such as discharge voltage, air flow rate, sphere size, the conductivity and initial concentration of the solution, TiO2 photocatalyst were studied. The experimental results proved that: the bipolar pulsed discharge plasma system has good degradation effect on TBBPA. Degradation of TBBPA increased with the increase of applied voltage. However better TBBPA removal rate was obtained at smaller bead diameter and low solution conductivity. Within a certain range, the air flow rate and the sphere size became smaller, the degradation effect was more excellent; TiO2 photocatalyst had a significantly enhancement on the degradation of TBBPA by the bipolar pulsed discharge plasma system. In the degradation process, TBBPA is broken down into small molecules and debromination was proved.
