Simple combination of biodegradation and carbon adsorption—the mechanism of the biological activated carbon process

摘要: This paper focuses on the mechanisms of the biological activated carbon (BAC) process. It is found that the bioregeneration hypothesis of desorption by exoenzymatic reactions is the common basis for some previous mechanisms. But by considering properties of the enzymes involved in the biodegradation pathway of phenols and aromatic hydrocarbons and distribution of exoenzymes in carbon pores, it is suggested that the hypothesis is not valid in most circumstances. A series of tests has been made in which phenol was used as …
