为了开发一种有效去除纺织印染污泥中有毒、致癌的多环芳烃（CPAHs）的方法，选择了5种CPAHs，利用超声波结合Fenton工艺（US/Fenton）研究其降解效率。结果表明，US/Fenton工艺对纺织印染污泥中CPAHs的降解具有显着的协同效应，协同度为30.4。在US/Fenton工艺中，低超声波密度在降解纺织印染污泥中的CPAHs方面表现出显着的优势。通过中心组合设计优化了CPAHs降解的关键反应参数为：H2O2浓度152 mmol/L、超声密度408 W/L、pH值3.7、H2O2与Fe2+摩尔比1.3、反应时间43 min。在US/Fenton工艺的最佳条件下，5种CPAHs的降解效率为81.23％（苯并[a]芘）至84.98％（苯并[a]蒽），并且5种CPAHs的苯并[a]芘当量（BaPeq）浓度下降了81.22-85.19％，这表明US/Fenton工艺去除有毒物质的高效力来自纺织印染污泥的 CPAH。
To develop an effective method to remove the toxic and carcinogenic polycyclic aromatic hydrocarbons (CPAHs) from textile dyeing sludge, five CPAHs were selected to investigate the degradation efficiencies using ultrasound combined with Fenton process (US/Fenton). The results showed that the synergistic effect of the US/Fenton process on the degradation of CPAHs in textile dyeing sludge was significant with the synergy degree of 30.4. During the US/Fenton process, low ultrasonic density showed significant advantage in degrading the CPAHs in textile dyeing sludge. Key reaction parameters on CPAHs degradation were optimized by the central composite design as followed: H2O2concentration of 152 mmol/L, ultrasonic density of 408 W/L, pH value of 3.7, the molar ratio of H2O2to Fe2+of 1.3 and reaction time of 43 min. Under the optimal conditions of the US/Fenton process, the degradation efficiencies of five CPAHs were obtained as 81.23% (benzo[a]pyrene) to 84.98% (benz[a]anthracene), and the benzo[a]pyrene equivalent (BaPeq) concentrations of five CPAHs declined by 81.22–85.19%, which indicated the high potency of US/Fenton process for removing toxic CPAHs from textile dyeing sludge.
