| Abstract: | Under the condition of indoor simulation, the influence factors including the heavy metal ion concentration, the adsorption time, the pH of waste water, the temperature, and the solid-liquid ratio, which affect the performace of removing heavy metals by sludge activated carbon in waste water, were explored. The results showed that when the concentrations of Cd^2＋ ,Zn^2＋ , Pb^2＋ Cu^2＋ are 40 mg· L^-1 , 10 mg· L^-1, 10 mg· L^-1, and 30 mg· L^-1,respectively, the adsorption was 90 rain, thepH was 4, the temperature was 25 ℃, and the solid-liquid ratio was 10 g ·L^-1 , the removal effect of Cd^2＋ , Zn^2＋ , Pb^2＋ , Cu^2＋ from waste water by sludge activated carbon achieved best, leading to the removal rate of more than 53 %. |
