Ex periments on Ni2+removal result by factors such as the amount of bentonite,adsorptio n time and pH value are made,and the effective rules have been found out.Their mechanism of action has been discussed.On the base of these experiments,the orthogonalexperiments are made with pH,amount of bentonite and amount of PAM and 3 levels to find out the best treatment processin wastew ater treatment containing Ni2+by combining bentonite with PAM (pH=8.5,concentration of bentonite is 5.0g/L,co ncentrationof PAM is 1.0mg/L).
Key words： bentonite; PAM; adsorption; flocculation; Ni2+
