Problems solved by technology

Among them, ion exchange and adsorption are also widely used, and activated carbon adsorption and exchange are commonly used; however, due to the characteristics of the pore structure of the activated carbon adsorption process, the treatment efficiency of heavy metal ions needs to be further improved, and the number of repeated uses after regeneration is less, and the adsorption efficiency not tall

Abstract

The invention discloses a water treatment material for heavy metal wastewater. The water treatment material is prepared from, by weight, 10-13 parts of psilotum nudum, 6-11 parts of horsetail, 7-10 parts of water chestnut root, 20-30 parts of phenolic resin, 12-15 parts of propylene glycol, 8-12 parts of salicylol, 7-12 parts of cellulose ether, 3-6 parts of 2-amino-5-nitrothiazole, 6-10 parts of 2-hydroxy ethyl acrylate, 2-6 parts of ammonium acetate, 3-7 parts of potassium oxonate and 4-8 parts of 3'-hydroxyacetophenone. The water treatment material is mainly prepared from phenolic resin modified by plants such as psilotum nudum, horsetail and water chestnut root. The treatment material is good in effect of adsorbing heavy metal ions and good in reuse effect after being regenerated simply.

Description

Technical field [0001] The invention belongs to the field of wastewater treatment materials, and particularly relates to a water treatment material for heavy metal wastewater and a preparation method thereof. Background technique [0002] While the rapid development of the national economy has brought people great material satisfaction, it has also brought a series of pollution problems. Especially for the pollution of water sources, water is the material that people rely on for survival. The heavy metal pollution is one of the biggest hazards that cause water pollution. The main sources of water pollution caused by heavy metals are: wastewater pollution from mining, metal smelting, metal processing, and chemical production; man-made pollution sources such as pesticides, fertilizers and household garbage. Due to their high toxicity, heavy metals cannot be metabolized and decomposed by themselves in the environment, and their bioaccumulation effects are obvious, they are likely ...
