Abstract

The invention relates to the technical field of water treatment, in particular to a filter material for treating heavy metals in industrial waste water. The filter material for treating the heavy metals in the industrial waste water is prepared from an absorbent A, an absorbent B, a chelating agent, sponge iron, volcanic, attapulgite and hydrogen peroxide; the absorbent A is prepared from coarse wheat bran, furnace ash and straw ash; and the absorbent B is prepared from herba nephrolepis cordifoliae, herba chenopodii ambrosioides, vetiver herb and herba carex gentilis. According to the filter material for treating heavy metals in industrial waste water, the coarse wheat bran, the furnace ash and the straw ash in the absorbent A and the herba nephrolepis cordifoliae, herba chenopodii ambrosioides, vetiver herb and herba carex gentilis adopted in the absorbent B are cheap and easy to obtain, so that the production cost is effectively decreased, safety and nontoxicity can be realized, water pollution is avoided, an effect for absorbing the metal in the waste water is good, the absorption of the absorbent B for the heavy metals is further induced by adding the chelating agent, and proteins such as metal sulfur proteins and plant chelating peptide in the absorbent B plays an important role in storing the metal.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a filter material for treating heavy metals in industrial wastewater. Background technique [0002] Industrial wastewater refers to the wastewater discharged in the process of industrial production, which will cause serious pollution to the environment. The chemical properties of the main pollutants contained in industrial wastewater can be classified into inorganic wastewater mainly containing inorganic pollutants, organic wastewater mainly containing organic pollutants, mixed wastewater containing both organic and inorganic substances, heavy metal wastewater, wastewater containing Waste water of radioactive substances and cooling water contaminated only by heat. Heavy metal wastewater contains a large number of toxic and harmful heavy metal elements, among which Zn, Pb, Cr, Cd, Hg, Mn and Ni are the most serious environmental pollution. At present, the filter material...
