Multifunctional composite absorbing material for purifying water and preparation method thereof

Abstract

The invention provides a multifunctional composite absorbing material for purifying water and a preparation method thereof, relating to an absorbing material. The invention provides the multifunctional composite absorbing material for purifying water, which can be used for effectively removing a plurality of harmful substances in the water and has higher removal efficiency and lower production cost, and the preparation method thereof. The absorbing material is selected from at least one of absorbing materials A, B and C; the absorbing material A takes a mesoporous adsorption ceramic material as a carrier to load nano metals including nano silver, nano zinc, nano iron and nano cerium; the absorbing material B takes the mesoporous adsorption ceramic material as the carrier to load nano metal oxides including nano titanium dioxide, nano zinc oxide, nano ferric oxide and nano cerium dioxide; and the absorbing material C is prepared from the following raw materials according to the mass ratio: 100-200 parts of active carbon powder, 20-30 parts of polyethylene powder, 10-30 parts of calcium sulfite powder, 10-30 parts of natural zeolite powder, 20-40 parts of macroporous acrylic resin and 10-20 parts of attapulgite powder.

Description

technical field [0001] The invention relates to an adsorption material, in particular to a multifunctional composite adsorption material for water purification and a preparation method thereof. Background technique [0002] With the development of society and the improvement of living standards, people have higher and higher requirements for quality of life, and clean and safe drinking water is the guarantee of people's quality of life. Access to clean and safe drinking water has become a hot topic worldwide. Water is the main carrier for the transmission of various germs, and 80% of human diseases are related to water pollution. At present, water pollution is becoming more and more serious. Surface water such as rivers and lakes and groundwater in some areas are polluted to varying degrees. The problem of water shortage has attracted widespread attention. [0003] The main pollutants in drinking water include soluble heavy metal ions, arsenic ions, trace organic pollutant...

AI Technical Summary

Problems solved by technology

[0009] 3. Skin damage caused by

[0020] 1. Very irritating and harmful to the respiratory system

[0021] 2. It is easy to react with organic matter in water to generate carcinogens such as chloroform

[0022] 3. If it is used as a raw material for production, it may have adverse effects. For example, when it is used to produce rice wine products, it has a bactericidal effect on the yeast in the fermentation process and affects the quality of the wine.

[0024] (1) Some organic substances are highly toxic persistent organic pollutants or endocrine disrupting substances, which are carcinogenic, reproductive toxic, sexual and other hazards, and pose a direct threat to human health;

[0025] (2) Some organic substances are precursors of disinfection by-products, which can form toxic halogenated organic compounds in the process of chlorine disinfection, which will endanger human health;

[0026] (3) Biodegradable organic matter in drinking water will cause harm to the water supply network and the water quality of the pipe network

[0028] The current adsorption materials are only for one or both substances in the water, and no harmful substances in the water have been adsorbed at the same time.
