Environment-friendly absorbing material for lead-containing industrial waste water

Abstract

The invention discloses an environment-friendly absorbing material for lead-containing industrial waste water. The environment-friendly absorbing material comprises the following substances in parts by weight: 3-5 parts of diluted hydrochloric acid, 6-9 parts of calcium carbonate, 9-14 parts of barium carbonate, 12-17 parts of vinyl-tri-(2-methoxyethoxy)-silicane, 3-7 parts of isodecyl acrylate, 2-6 parts of isopropyl acrylate, 50-60 parts of shaddock peel, 3-8 parts of acrylic high-molecular water absorbing resin, 3-5 parts of bentonite, 1 part of carboxymethyl methyl cellulose, 1 part of hollow glass microbead, 9-16 parts of nano silica gel and 4-6 parts of nano-level zinc oxide. The environment-friendly absorbing material disclosed by the invention has the beneficial effects that the surface area is large, the absorbing capability is strong, simultaneously, the diffusion resistance is low, the balance time in the absorbing process is short, and the whole process is fast and efficient. The adsorbed magnetic nano material can be regenerated for reuse.

Description

technical field [0001] The invention relates to an environment-friendly and energy-saving nanometer material for absorbing lead-containing industrial waste water. 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 we...
