Problems solved by technology

[0003] However, ordinary activated carbon fibers are easy to saturate, poor in strength, dusty, and the adsorption capacity will decrease with the use time, resulting in uneven water quality; after a short period of use, the adsorption function will be lost, and it needs to be replaced frequently, which is expensive
At the same time, due to the different quality of domestic raw water and the large difference in impurity components, pure activated carbon fibers cannot be absorbed thoroughly for a long time, resulting in certain limitations in its application range.

Abstract

The invention provides a composite activated carbon filter element which comprises the following components in parts by weight: 3-6 parts of activated carbon fiber cloth, 3-9 parts of wood carbon, 25-32 parts of coconut shell activated carbon and 2-3 parts of acrylic glue. Adsorption properties of various carbon materials of the composite activated carbon filter element provided by the invention can supplement one another, so that the adsorption efficiency is greatly improved, and the effective use time is prolonged. Compared with a common activated carbon filter element, the composite activated carbon filter element is relatively large in adsorption specific surface area, relatively dense in structure, relatively rich in porosity, relatively high in strength, not liable to crush and relatively small in dust amount, the adsorption effect is 10 times better than that of the common activated carbon filter element and is 25 times better than that of granular activated carbon, and water purified by using the filter element is relatively pure in taste.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a composite activated carbon filter element and a preparation method thereof. Background technique [0002] Activated carbon fiber has a developed specific surface area and narrow pore size distribution. It has the functions of absorbing different colors, odors and residual chlorine in water, and has a good removal effect. Therefore, it is widely used in water quality treatment in many fields such as food, medicine, chemical industry, and environmental protection. in process. [0003] However, ordinary activated carbon fibers are easy to saturate, poor in strength, dusty, and the adsorption capacity will decrease with the use time, resulting in uneven water quality; after a short period of use, the adsorption function will be lost, and it needs to be replaced frequently, which is expensive. At the same time, due to the different quality of domestic raw water and the l...
