摘要

The extent to which microbial activity is enhanced by the presence of substrate adsorbed on activated carbon is examined and the influence of ozonation on this process is investigated. It was found that microbial growth rate constants were as much as 100 percent higher on activated carbon than on non-adsorbing media. Ozonation was found to alter adsorbility, but this was dependent upon the reactivity toward the test compounds. In most cases, the adsorbability of the mixture was decreased by ozonation. It is concluded that biodegradation and adsorption are interactive processes in water and wastewater treatment and that bioregeneration can account for renewal of adsorption sites and additional removal capacity. Ozonation was found to affect both adsorption and biodegradation.
