Abstract
Many of the persistent and recalcitrant organic chemicals found in a wide variety of industrial wastewaters are potentially toxic to human beings and microorganisms. Such organics have been listed as priority pollutants. Because of their stable structures, and to these is added the possibility of a highly oxidized state, such organics are typically not easily degraded under aerobic conditions. This review aims to offer insights into the development and the application of anaerobic granulation technology for treatment of wastewaters containing such potentially inhibitory substances (e.g., phenol, nitrophenol, chlorinated phenolic compounds, chlorinated hydrocarbons, polychlorinated biphenyls, phthalic esters, benzoate, chlorobenzoate).
