%X The synthesizing method of heavy metal chelating agent was explored in this paper.The technology process and treatment efficiency of the chelating agent in treating with fly ash were experimentally studied.The results indicated that the efficiency of heavy metal chelating agent in treating with fly ash was higher than that of using Na2S and lime,futhermore,the treated fly ash using this chelating agent can reach the landfilling standards for heavy metal waste.The maximum leaching quantity of heavy metal for the treated fly ash using this chelating agent was much lower than that for the treated fly ash using Na2S and lime,and it can keep stabilization within a broader pH value.Thus the risk of secondary pollution for the treated waste was reduced dramatically when the environment condition changes.
