From 1998 to 2018, more than 5,000 articles concentrated on the research of antibiotic wastewater treatment have been published. Among them, photocatalysis has received much attention due to its green and environmental-friendly properties. In this mini-review, the recent progress of photocatalysis in antibiotic wastewater was summarized, including antibiotics degradation and hydrogen energy conversion. The photocatalysts commonly used were also discussed. It can be mainly classified as TiO2-based materials, sulfides and polymeric carbon nitride-based materials and bismuth-contained materials. Four major types of antibiotics, tetracycline, sulfonamide, β-lactam and quinolone, were involved. Furthermore, perspectives concentrated on future development and challenges, especially converting antibiotics into hydrogen energy, were also proposed.展开更多

These processes can be used alone or in combination with each other or by complementing traditional methods, even allowing the disinfection of bacterial and viral inactivation. With the use of experimental systems UV/H202/O3, UV/H202, it can achieve total mineralization of the compound. Ciprofloxacin solutions used at 50, 100, 200, 300, 400 and 500 ppm, degraded to 100% of antibiotics and by a microbiological method show that the loss of biological activity is inversely proportional to the time of irradiation.展开更多
