| Abstract: | The optimal conditions for treatment of wastewater containing high density arsenic by using heavy metal chelating agent were found via orthogonal test method. The comparison of efficiency and cost of treatment between this novel method and the conventional method was also carried out. The results showed that the efficiency of the novel method is higher and the treated wastewater can reach the wasterwater discharge standards. Moreover, the amount of sludge is reduced and the post treatment is simplified. |
