ADSORPTION MATERIAL FOR TREATING WASTE WATER CONTAINING ARSENIC, ANTIMONY AND MOLYBDENUM, PREPARATION METHOD THEREOF AND METHOD FOR TREATING WASTE WATER CONTAINING ARSENIC, ANTIMONY AND MOLYBDENUM THEREWITH

The invention provides an adsorbing material for treating wastewater containing arsenic, antimony and molybdenum, a preparation method of the adsorbing material and a method for treating the wastewater containing arsenic, antimony and molybdenum by using the adsorbing material. The preparation method of the adsorbing material for treating the wastewater containing arsenic, antimony and molybdenum comprises the following steps: mixing activated carbon and nitric acid, carrying out first heating treatment, then cooling, washing with water, and drying at constant temperature to obtain modified activated carbon; the method comprises the following steps: mixing ferric salt, ethanol and a trimercapto-s-triazine trisodium salt solution to obtain a loaded solution; mixing the modified activated carbon, the loading solution, ammonia water and a mercaptopyridine polyethylene glycol carboxyl solution, and carrying out second heating treatment to obtain a primary adsorption material; and cleaning the primary adsorption material, and then carrying out vacuum drying to obtain the adsorption material for treating wastewater containing arsenic, antimony and molybdenum. The adsorption material provided by the invention is high in adsorption efficiency and low in treatment cost.
