Environment-friendly energy-saving nanometer material adsorbing lead-containing industrial wastewater

Abstract

A disclosed environment-friendly energy-saving nanometer material adsorbing lead-containing industrial wastewater is characterized by comprising the following substances in parts by weight: 1-6 parts of dilute hydrochloric acid, 10-30 parts of ferric chloride, 9-16 parts of ammonia water, 3-9 parts of polypropylene fiber, 4-8 parts of aramid fiber, 2-8 parts of hollow glass bead, 1-7 parts of graphite powder, 3-6 parts of anatase type titanium dioxide, 1-3 parts of lithopone, 1-8 parts of organosilicon modified epoxy resin, 0.5-1 parts of a nanometer-level particle inorganic material, 4-8 parts of calcium carbonate, 4-6 parts of nanometer-level zinc oxide. The beneficial effects comprise that the nanometer material is large in specific area, high in adsorption capability, also small in diffusional resistance, short in balance time during adsorption, and fast and efficient in the whole process; and the adsorbed magnetic nanometer material is regenerable and reusable.

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...
