“…There are multiple transition metal elements that can initiate the Fenton-like catalytic process, including Fe, Cu, Mn, and Pb [63,64], while Fe-based catalysts and Cubased catalysts are common ones. Fe-based Fenton-like catalysts consist of synthetic catalysts such as MnFe 2 O 4 /biochar, Fe-Mo/rGo [15], Fe/Cu@γ-Al 2 O 3 [16], and Fe/Acidmontmorillonite [65], iron ores, solid waste such as coal fly ash, slag, and gangue [6,[66][67][68][69], and zero-valent iron. Table 3 summarizes the system, reaction conditions, and effects of typical ultrasound and FE methods for degrading organic wastewater.…”

“…In these physical fields, the ultrasound field is different from other physical fields because it belongs to a mechanical field, while other physical fields belong to the electromagnetic field; ultrasound works by relying on high-frequency vibrations and a subsequent cavitation effect [16]. According to the definition from the American National Standards Institute, ultrasound is a type of dense longitudinal wave with a frequency of >20 kHz; it can 2 of 24 be generated by a piezoelectric effect (generated by the interaction of mechanical pressure and electricity) or magnetostriction (generated in electromagnetic fields) [17].…”

Ultrasound waves have been widely used in the field of organic wastewater treatment due to their mechanical, thermal, and chemical effects derived from their cavitation effect. Many researchers have combined ultrasound waves with other organic wastewater treatment methods because they have the potential to offset the disadvantages of other methods. In recent years, many authors within the literature have reviewed the application of ultrasound combined with a certain wastewater treatment method. In this review, we introduce the working mechanism of ultrasound in the treatment of organic wastewater and then examine the synergistic effects of ultrasound with other organic wastewater treatment methods based on various applications, indicating a strong synergistic effect between ultrasound and other wastewater treatment methods. Subsequently, we introduce typical ultrasound-enhanced organic wastewater treatment equipment and propose some possible developmental directions for ultrasound in the treatment of organic wastewater.
