The modification of Na-bentonite and Ca-bentonite by Al2(SO4)3 have been studied. The effectiveness for treating phenol-based chemical industry wastewater by modified bentonite is studied, too. The optimum conditions as adding quantity of modified bentonite, pH, agitation time are determined. The experimental results showthat the removal rate of phenol can be up to 78.5%, and the rate of COD and oil in the wastewater is 75.2% and 94.2%.
Key words: aluminium sulfate; modified bentonite; phenol-based wastewater
