| description | The invention provides a fly ash composite agent and a preparation method thereof. The fly ash composite agent comprises the following components: inorganic aluminum salt; manganese sulfate; reducing iron powder; activated carbon; wherein the mass ratio of the inorganic aluminum salt to the manganese sulfate to the reducing iron powder to the activated carbon is (1-2): (0.5-1): (1.5-2): (0.5-1), and the purity of the inorganic aluminum salt, the purity of the manganese sulfate, the purity of the reducing iron powder and the purity of the activated carbon are all larger than or equal to 90%. The fly ash composite agent has the beneficial effects that the inorganic aluminum salt, the manganese sulfate, the reductive iron powder and the activated carbon are mixed together according to a specific proportion to prepare the specific fly ash composite agent, and in the actual use process, the fly ash composite agent can effectively remove lead, cadmium and zinc in fly ash and also can be used for preparing the fly a |
