Abstract
Abstract
Antibiotics have become a new type of organic pollutant. Traditional methods of antibiotic treatment have several problems, including low treatment efficiency, high cost, and low safety. As an emerging process intensification technology, hydrodynamic cavitation (HC) can significantly enhance degradation efficiency coupling with other treatment means. This work studies the degradation effect of a representative antibiotic, tetracycline, by combining HC and UV. The effect of various operating factors, including inlet pressure, initial concentration, pH, and temperature, is analyzed. It is found that HC/UV can obtain 1.7∼4.2 times more effectiveness than that of sole use of HC or UV.
