Antibiotics are removed from the environment by a series of biological transformation processes, including adsorption,migration and degradation and so on.Hydrolysis,photolysis and biological degradation are the common ways of degradation,while the last one is the main form, and the degradation by drug-resistant strains is particularly important. Hydrolysis is affected by pH, photosensitizer, soil moisture, and other oxidants can significantly speed up the photolysis, and the growth condition of microorganis...
