Embodiment Construction

[0025] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0026] refer to figure 1 Shown, an embodiment of the present invention is a kind of method for activated carbon fiber on-line regeneration, and the method comprises and preferably carries out according to the following steps:

[0027] Step A, immersing the activated carbon fiber in a closed container filled with water, and connecting the activated carbon fiber to the DC electrode;

[0028] Step B, continuously inject ozone into the water inside the airtight container within the first fixed time;

[0029] Step C. After the first fixed time, empty the water inside the airtight container, re-inject water that has not passed the activated carbon fiber into it again, and disconnect the electrode connected to the activated carbon fiber, and heat the water in the airtight container to boiling, and keep it boiling for a second fixed time;

[0030] Step D. After the second ...

Abstract

The invention discloses an online activated carbon fiber regeneration method, and belongs to an application mode of activated carbon fibers. The online activated carbon fiber regeneration method comprises the steps of A. immersing activated carbon fibers in a closed container with water, and connecting the activated carbon fibers into a direct current electrode; B. constantly injecting ozone into the water in the closed container within first fixed time; C. after the first fixed time, draining the water in the closed container, then injecting water at least submerging the activated carbon fibers into the closed container again, disconnecting the electrode from the activated carbon fibers, and heating the water in the closed container to be boiled, wherein the water in the closed container is kept in the boiled state in second fixed time. As ozone replaces chlorine dioxide, the influence on water purification of the activated carbon fibers caused by chloride ions is effectively alleviated. The water in the container is heated in an electric heating manner, and electric heating equipment is simpler in structure compared with automatic steam equipment, so that the use cost is low, and the online activated carbon fiber regeneration method is easy to popularize and use.

Description

[0001] technical field [0002] The invention relates to an application mode of activated carbon fibers, and more specifically, the invention mainly relates to a method for online regeneration of activated carbon fibers. [0003] Background technique [0004] At present, the activated carbon fiber on-line regeneration method adopted by the activated carbon fiber filter device on the market is generally connected to the AC electrode, and chlorine dioxide is injected into the water, combined with the method of steam heating the water. The main defect of this method in practical application is: the electric field formed by alternating current is unstable, which is not conducive to the adsorption of ions in the water on the electrode, resulting in poor electrochemical effect, and then the water purification effect is worse than direct current; at the same time, chlorine ions themselves As a harmful substance, it is one of the pollution factors that need to be controlled in wate...
