摘　　要：超声技术对降解酯类化合物、聚合物等难降解有机物有较好的处理效果,本试验研究超声强化对 CuO/Al_(2)O_(3)类芬顿体系对处理印染退浆废水中 PVA 废水去除效果的影响。通过添加超声波强化来处理 PVA 废水,研究此联用体系对有机物去除率的提升效果。在单独使用超声波技术降解 PVA 废水后,研究超声功率、频率等因素对强化类芬顿体系降解能力的影响,并通过试验与讨论确定最佳运行条件,比较经过超声强化后的类芬顿体系和单独类芬顿体系对污染物的降解效果,从而改善单独类芬顿体系投药量过多、催化剂重复使用次数少的问题。Ultrasonic technology has good treatment effect on the degradation of ester compounds, polymers and other refractory organics. In this paper, the effect of ultrasonic enhancement on the effect of CuO/Al_(2)O_(3)Fenton system on the treatment of polyvinyl alcohol (PVA) in printing and dyeing desizing wastewater was investigated. The PVA wastewater was treated by adding ultrasonic enhancement, and the effect of this combined system on the removal rate of organic matter was studied. After ultrasonic technology was used to degrade PVA wastewater, the influence of ultrasonic power, frequency and other factors on the degradation ability of the enhanced Fenton system was studied, and the best operating conditions were determined through experiments and discussions, and the ultrasonic enhanced Fenton-like system was compared with the single-type Fenton system. The problem of excessive dosage of the single Fenton system and less repeated use times of the catalyst was solved.
