Problems solved by technology

[0003] Adsorption materials have been widely used in wastewater and waste gas treatment, and have good results, but there are common problems such as high desorption costs (high temperature activation or chemical activation), and continuous operation during desorption.
[0004] Negative ion materials can continuously release hydroxyl anions and emit far-infrared rays, which have been widely used in indoor air purification applications, but the effect of independent completion of wastewater degradation and activation is not significant enough

Abstract

The invention belongs to the field of waste water and waste gas treatment, and particularly relates to a composite material with the photocatalysis function and the anion adsorption function and a production method thereof. The composite material comprises a solid dry material and water. The solid dry material comprises, by mass, 40-70 parts of inorganic gel materials, 5-15 parts of photocatalysis materials, 10-30 parts of active adsorption materials, 5-10 parts of anion materials, 5-10 parts of reinforced fiber materials, 4-6 parts of inorganic transparent particles, 0.5-3 parts of foaming agents and low-density organic materials. The proportion of the solid dry material to the water is 1 to 0.5-2, and the volume weight of a finished product is 60-700kg/m<3>. The composite material is an inorganic composite porous large-specific-surface-area profile integrating the functions of adsorption, catalytic decomposition, desorption, hydroxyl anion relase and infrared emitting. Ball-shaped, block-shaped, bar-shaped and plate-shaped porous profiles are provided.

Description

technical field [0001] The invention belongs to the environmental protection field of waste water and waste gas treatment, and in particular relates to a composite material with functions of photocatalysis and negative ion adsorption and a production method thereof. Background technique [0002] Since the photocatalytic semiconductor technology was discovered in Japan in 1967, many scientific research institutions around the world have carried out a lot of research and development. Except for indoor air purification, it has not been widely promoted in industrial wastewater treatment. The reason is that Technical characteristics of photocatalytic materials: 1. Photocatalytic degradation reactions only occur at the interface; 2. Photocatalysis has no selectivity for degradation objects, and organic polymer carriers are damaged by photoerosion; 3. Inorganic carrier materials are subject to manufacturing, chemical corrosion, water resistance Many influences have affected the lar...
