In response to sudden phenol pollution accidents,the adsorption performance of activated carbon,carbon fiber,bentonite and fly ash were studied,and the effects of the adsorption time and temperature conditions on activated carbon were studied too.The results indicates that the activated carbon is the most appropriate adsorption material.The adsorption time should be preferably more than 60 min.With the dosage of activated carbon increasing,the removal rate rise rapidly,and then flatten.With the phenol initial concentration increasing,the removal rate decreased slightly.When the sudden phenol pollution accidents occurred in the river,the activated carbon interception and adsorption nets should be set.
