Composite resin material for adsorbing lead-containing wastewater

Abstract

The invention discloses a composite resin material for adsorbing lead-containing wastewater. The composite resin material for adsorbing lead-containing wastewater comprises the following substances in parts by weight: 15-20 parts of ethyl acetate, 22-30 parts of triethylamine, 19-25 parts of tartaric acid, 17-26 parts of methyl benzoate, 19-23 parts of tetra-pentaerythritol ester, 16-30 parts of polyvinyl chloride resin, 25-34 parts of furane resin, 1-3 parts of an initiator, 11-20 parts of nitric acid, 9-16 parts of sodium hydroxide, 3-7 parts of potassium hydroxide, 1-3 parts of hydroxyethyl cellulose, 5-9 parts of POE, 10-18 parts of nano organic montmorillonite, 5-16 parts of sepiolite and 10-35 parts of medical stone. The composite resin material for adsorbing lead-containing wastewater has the beneficial effects that the specific surface area is large; the adsorption capability is high; meanwhile, the diffusion resistance is low; the balance time is short in the adsorption process; the whole process is rapid and efficient; a magnetic nano material after adsorption can be recycled after being regenerated.

Description

technical field [0001] The invention relates to a composite resin material for absorbing waste water containing lead. Background technique [0002] my country is the third largest mining country in the world, with more than 4,000 mines of various types. The mining, smelting and processing of mineral resources have caused serious damage and pollution to ecology and the environment. It is estimated that the directly polluted soil area in my country is at least 2 million hectares, and the pollution of water resources such as oceans is even worse. In addition to the heavy metal emissions from other industries, my country's heavy metal pollution has reached a level that seriously affects people's health and environmental safety. Lead has toxic effects on various systems and organs throughout the body. It can inhibit many enzymes in the process of heme synthesis in the body, and cause serious damage to the central nervous system, as well as nervous system, hematopoietic system, u...
