摘要:
系统考察了在不同Fe（Ⅵ）/TBBPA（1∶1~5∶1）、pH（5.0~9.0）和温度（10~50 ℃）条件下，高铁酸盐氧化法对四溴双酚A（TBBPA）的降解效果以及对急性、慢性、遗传毒性的控制情况，利用潜在生态毒性效应指数（PEEP）对处理后废水的综合生物毒性进行评价。结果表明，当Fe（Ⅵ）/TBBPA为4∶1、pH为7.0、温度为25~30 ℃时，TBBPA可被完全降解。TBBPA本身以慢性毒性为主（TU高达41.7），急性、遗传毒性均较低，高铁酸盐氧化法在降解TBBPA过程中可有效控制废水的各项毒性。当Fe（Ⅵ）/TBBPA为4∶1时，急性、慢性毒性可分别降至0.06、0.95 TU，均满足美国废水排放毒性标准；水样致突变比均小于2.0，无遗传毒性风险。综合生物毒性评价表明，高铁酸盐氧化法在较低的Fe（Ⅵ）/TBBPA（4∶1）、较宽的pH范围（5.0~9.0）和温度范围（20~30 ℃）范围内均可控制PEEP低于2.0，出水无毒性风险，表现出较强的适应性。
Abstract:
Under different Fe(Ⅵ)/TBBPA ratios (1∶1-5∶1), pH (5.0-9.0) and temperatures (10-50 ℃), the ferrate(Ⅵ) oxidation for the degradation of tetrabromobisphenol A (TBBPA) and the control of acute, chronic and genetic toxicities were investigated, and the comprehensive biotoxicity of the treated wastewater was evaluated by potential ecotoxic effect index (PEEP). When the ratio of Fe(Ⅵ) to TBBPA was 4∶1, the pH was 7.0, and the temperature was 25-30 ℃, the TBBPA could be completely degraded. The TBBPA itself mainly demonstrated chronic toxicity (TU value as high as 41.7), and both of its acute and genetic toxicities were low. The ferrate oxidation effectively controlled the toxicity of wastewater in the degradation of TBBPA. When the ratio of Fe(Ⅵ) to TBBPA was 4∶1, the acute and chronic toxicities were reduced to 0.06 TU and 0.95 TU, respectively, and the corresponding toxicity controlling rates met the toxicity standards of wastewater discharge in the United States. In addition, the mutagenic ratio of water sample was less than 2.0, indicating that there was no genotoxicity risk. The comprehensive biotoxicity evaluation showed that the ferrate oxidation method could control the PEEP below 2.0 at low Fe(Ⅵ)/TBBPA ratio (4∶1) and wide pH range (5.0-9.0) and temperature range (20-30 ℃), and there was no toxicity risk of the effluent. The results demonstrated that the method had strong adaptability.
