Composite adsorption material for treatment of industrial waste water and preparation method thereof

Abstract

The invention relates to a composite adsorption material for treatment of industrial waste water and a preparation method thereof. The composite adsorption material is characterized by comprising 5 to 15 parts of polyaluminum silicate sulfate, 3 to 10 parts of polyaluminum chloride, 4 to 8 parts of macroporous adsorption resin D1300, 4 to 9 parts of macroporous adsorption resin H103, 3 to 8 parts of polyethelene alcohol fiber, 2 to 5 parts of Arabic gum, 4 to 9 parts of hydroxypropyl chitosan, 3 to 7 parts of barium sulfate and 4 to 7 parts of lithium carbonate. The preparation method comprises the following steps: step 1, crushing barium carbonate and lithium carbonate with a crusher until the particle size of both barium carbonate and lithium carbonate is 150 to 300 meshes; and step 2, respectively weighing the above-mentioned components according to weight parts and uniformly mixing the components to prepare the composite adsorption material for treatment of industrial waste water.

Description

technical field [0001] The invention belongs to the field of environmental treatment, and relates to a composite adsorption material and a preparation method thereof, in particular to a composite adsorption material for industrial wastewater treatment and a preparation method thereof. Background technique [0002] Conventional wastewater treatment processes such as activated sludge and trickling filtration can remove a variety of organic substances through biological oxidation. This treatment process can remove almost all the organic matter that constitutes BOD, but it cannot effectively remove the refractory organic matter that constitutes COD. Even the well-treated secondary effluent still contains 50-120mg / L organic matter, these substances include tannins, wood Toxins, humus, ethers, protein-containing substances and other substances that produce color and odor, as well as herbicides and insecticides. [0003] The adsorption method can remove most of the refractory orga...
