The invention provides an anaerobic granular sludge-loaded sulfided nano-zero-valent iron adsorption material, which uses anaerobic granular sludge as a base material, ferrous sulfate as an iron source, sodium borohydride as a reducing agent, and sodium hydrosulfite as a vulcanizing agent , obtained by composite reaction; its form is sulfided nano-zero-valent iron loaded on the surface of anaerobic granular sludge. The adsorption material of the invention has significantly improved adsorption performance for heavy metal ions or semi-metal ions, and can be used for adsorbing heavy metal ions or semi-metal ions in waste water, so as to solve the pollution problem of heavy metal ions and semi-metal ions in waste water, and can also solve anaerobic problems at the same time. The disposal of the remaining anaerobic granular sludge discharged from the reactor and the problems of easy loss and easy agglomeration when sulfided nano zero-valent iron is used as a single adsorption material. |
