中文摘要：

采用紫外（UV）光解技术作为四溴双酚A（TBBPA）工业废水的预氧化技术,考察了光照时间、pH值、TBBPA浓度、紫外辐射强度等因素对降解TBBPA效果的影响。结果表明：紫外光解可有效改善TBBPA工业废水的可生化性,在pH=11、TBBPA初始浓度为50 mg/L,紫外辐射强度为8mW/cm2,温度控制在25℃条件下,反应210 min,B/C可提高至0.28。同时,各影响因素下TBBPA动力学降解特性的研究表明,TBBPA的光解过程符合一级反应动力学模型。

英文摘要：

In this paper,UV degradation as a pre-treatment technology is used to improve the biodegradability of wastewater containing tetrabromobisphenol-A（TBBPA）.The effect factors of irradiation time,initial pH,initial concentration of TBBPA and UV light intensity are investigated in the process.The results indicate that under the conditions of ρ（TBBPA）=50 mg/L,pH=11.0,UV light intensity is 8 mW/cm2,temperature is 25 ℃ and reaction time is 210 min,the biodegradability of the wastewater containing TBBPA could be effectively improved by UV degradation,and the ratio of BOD to COD is increased from 0 to 0.28.Moreover,results of kinetic test show that TBBPA photodegradation in different condition tests follows the first-order.
