高效非均相类芬顿催化剂降解实际抗生素废水的研究进展

Heterogeneous Fenton-like oxidation technology，which has the advantages of strong oxidation ability and mild reaction conditions, is a promising antibiotic wastewater treatment technology. Due to the slow solid-liquid mass transfer process, the catalytic activity of heterogeneous Fenton-like catalysts is not ideal. In this paper, strategies for optimizing catalytic activity, such as doping, composite, photo-assisted and electro-assisted, were introduced to efficiently and rapidly treat antibiotic wastewater. However, in the actual antibiotic wastewater, the concentration of antibiotics and other residual substances could affect the efficiency and rate of degradation. This review summarized the effects of antibiotic concentration, coexisting anions and cations, and natural organic matter on antibiotic degradation. It was found that heterogeneous Fenton-like catalysts could not rapidly degrade high-concentration antibiotic wastewater. Coexisting anions and high-concentration natural organic matter would compete with antibiotics for active species, resulting in poor degradation of antibiotics.
