Composite material comprising photocatalyst and phenolic resin group active carbon and preparation method thereof

Abstract

The invention relates to a composite of decomposing organic phenol- containing waste water, namely a photocatalyst-Arcolitebased active carbon composite, as well as its preparing method. Its character: Arcolite 40-100 shares; photocatalyst 10-50 shares; active agent 20-100 shares. Its preparing method: (1) batching; (2) carbonizing: proportionally mixing powdery Arcolite and photocatalyst powder to finely mill, screening by 200-eye sieve, and then carbonizing into powdery carbon after 1-4 hours under the protection of nitrogen gas; (3) activating: fully mixing the powdery carbon with the active agent in the weight proportion to activate for 2-4 hours under the protection of nitrogen gas, cooling the product to fully wash by water to eliminate alkali component, and then drying to obtain the finished product. Under the action of ultraviolet ray, it can make high-efficiency decomposition on organic and harmful matters of organic phenol; its production process is simple and its production cost is low.

Description

technical field [0001] The invention relates to a composite material for decomposing and treating organic phenol-containing wastewater and a preparation method thereof, in particular to a photocatalyst-phenolic resin-based activated carbon composite material and a preparation method thereof, which is suitable for decomposing and treating phenol-containing wastewater and other organic-toxic wastewater (such as Organic wastewater containing benzene, wastewater containing organic pesticides, wastewater containing organic sulfur, etc.). Background technique [0002] Scientific research has confirmed that phenol wastewater contains a large amount of harmful substances such as carcinogens and environmental hormones, and has a wide range of sources, posing a serious threat to human life and the environment. It is one of the key monitoring and treatment objects in all countries in the world. The phenol content in sewage entering urban sewers should not exceed 1.0 mg / L. At present, d...

[0002] Scientific research has confirmed that phenol wastewater contains a large amount of harmful substances such as carcinogens and environmental hormones, and has a wide range of sources, posing a serious threat to human life and the environment. It is one of the key monitoring and treatment objects in all countries in the world. The phenol content in sewage entering urban sewers should not exceed 1.0 mg / L. At present, domestic and foreign treatment methods generally include activated carbon adsorption, biodegradation, and photocatalytic degradation. Long, high cost and other disadvantages

In recent years, Japan has successively developed photocatalyst inorganic gel coated on the surface of activated carbon, porous ceramics, and porous metal to make porous photocatalytic composite materials (Japanese Patent Application No. 2001-232206, Patent Application No. 8-196903). Collecting organic and toxic substances is beneficial to improve the efficiency of photocatalysts in decomposing organic and toxic substances. However, since photocatalysts are only coated on the surface of porous substances and cannot enter the porous interior, the efficiency of photocatalysts in decomposing organic and toxic substances will be further improved. At the same time, due to the photocatalyst coating, which reduces the surface area of ​​porous substances
