Activated carbon fiber for treating oily wastewater as well as regeneration method and device of activated carbon fiber

[0057] An activated carbon fiber treatment of oily wastewater and its regeneration device, including a reactor 1, a nozzle installed on the reactor 1, and an electric mixer 4 (the mixer is located at the bottom of the reactor, not shown in the figure), in the reactor 1 Multiple sets of alternately arranged anodes 6 and cathodes 7 are provided, and the anodes 6 and cathodes 7 are respectively introduced into the reactor through wires or plates to connect to an external DC power supply.

[0059] On the basis of the above-mentioned embodiment 1, the anode is an activated carbon fiber felt wrapped on a titanium-based metal oxide as the anode, and the cathode is a pure titanium metal as the cathode. And both the titanium-based metal oxide and the pure titanium metal have a network structure.

[0061] On the basis of the above-mentioned Example 1 or Example 2, the nozzles arranged on the reactor include: the auxiliary regeneration liquid inlet 2 at the top of the reactor 1, the exhaust port 3, the waste water outlet 5 and the outlet at the reactor 1 Auxiliary regeneration fluid outlet 8 and waste water inlet 9 at the bottom. Through the setting of specific nozzle positions, the wastewater treatment process adopts low-level inlet and high-level outlet, which is more conducive to its full degradation; the auxiliary regeneration liquid adopts high-level inlet and low-level outlet, which is more convenient for operation and improves work efficiency.

[0062] Next, the method part of the present invention is further described by the following examples
