Abstract
A device for decomplexation and enhanced removal of copper based on self-induced Fenton-like reaction constructed by electrochemistry coupled with membrane separation is disclosed. The device includes a reactor, two electrocatalytic anodes capable of generating hydroxyl radicals, an electrocatalytic cathode membrane assembly, a direct current power supply, an aeration system, an inlet pipe and an outlet pipe. The device of the present invention has a simple construction. Using this device to treat industrial wastewater containing copper complexes under specific conditions allows the decomplexation and the removal of the industrial wastewater containing the copper complexes to be simultaneously realized at a low consumption and a high efficiency. The coupling of electrochemistry with membrane separation can be achieved to protect the cathode from being contaminated by pollutants in the sewage and prolong the service life of the electrode.
