通过烧杯试验，对比研究了不同因素对高铁酸盐和臭氧氧化降解双酚 A 的影响，并对试验过程中的生物毒性进行了对比分析。试验结果表明：针对质量浓度为1 mg / L 的双酚 A 模拟废水，在高铁酸盐和臭氧的投加量分别为5.0和1.20 mg/ L 的条件下，高铁酸盐降解双酚 A 的能力更强，去除率达到91.6%，而臭氧氧化法仅为80.9%；同时，高铁酸盐法具有更广的 pH 值（3~11)和温度（10~50℃)适应性。不同的干扰离子对氧化体系的影响不同， HCO3-对2个氧化体系均具有一定的促进作用； Fe3+的存在具有催化作用，有利于臭氧氧化降解双酚 A，但是不利于高铁酸盐的稳定性从而不利于双酚 A 的脱除。2种方法处理后水的生物毒性均随反应时间的延长呈先升高后降低的趋势，相对而言，高铁酸盐法对处理后水的毒性控制效果更佳。

Through the beaker tests, the degradation of bisphenol A(BPA) by ferrate and ozone oxidation was studied contrastively by investigating the effects of different influencing factors as well as analyzing the vari-ation of biotoxicity during the two processes. The results of the test showed that, on the premise that the dosage of BPA and ozone were 5.0 and 1.20 mg / L respectively, ferrate showed a stronger degrading ability when treating BPA simulated wastewater with mass concentration of 1 mg/L. The removal rate of BPA reached 91.6% by ferrate while only 80.9% by ozone oxidation. In addition, ferrate oxidation process had a wider pH value(3 ~ 11) and temperature(10 ~ 50 ℃) adaptive range. Different interfering ions had different effects on the oxidization system. HCO3- showed a certain promoting effect on the said two systems, Fe3+ played a catalytic role during the reaction, which was favorable for BPA degradation by ozone; however, it was not conductive to the stability of the ferrate, thus was not beneficial to BPA degradation. The biotoxicity of the effluent water from the said two processes showed the tendency that increased first and then decreased with the prolonging of the reaction time. It could be seen that, compared to ozone, ferrate had a better effect for water toxicity controlling.
