摘要： 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.

摘要： An electrochemical membrane module for selectively removing pollutants and a preparation method thereof are provided. A Ti/SnO2—Sb substrate electrode is coated with a MI-TiO2 sol-gel by means of a dip-coating method, and then sintered to obtain a molecular imprinting type Ti/MI-TiO2/SnO2—Sb coated electrode; the coated electrode is adhered to a ceramic micro-filtration membrane using epoxy resin glue to obtain a Ti/MI-TiO2/SnO2—Sb MI-anodic conductive composite membrane; the MI-anodic conductive composite membrane is used as an anode, and a titanium mesh is used as a cathode, so that the electrochemical membrane module capable of selectively removing pollutants is obtained. The invention effectively combines an electrochemical micro-filtration membrane and a molecular imprinting technique. When the electrochemical membrane module is used, suspended particles and refractory organics in the sewage are removed, and a highly selective removal of certain refractory pollutants can be achieved.

摘要： To provide a modified forward osmosis (FO) membrane module for flow regime improvement, the FO membrane module includes but not limited to: a water inlet; a water outlet; a forward osmosis (FO) membrane; a frame; and folded plates for improving flow regime in which draw solution is introduced into the water inlet of membrane module, then flowed through flow channels composed by three opposite folded plates vertically arranged on upper and bottom portions of the frame alternatively along horizontal direction with equal space; and drawn out from the water outlet. The flow regime improvement is achieved by increasing number of flow-guide folded plate, which results in the decrease of internal concentration polarization and membrane fouling. Structure of frame is modified to improve flow regime and to satisfy requirement of convenient and reliable connections between numbers of membrane modules in the FO membrane system.

摘要： This present disclosure relates to a highly effective sewage treatment based on regulation and control of directed electron flow and apparatus thereof The apparatus includes an anaerobic fermentation electron generation chamber, a heterotrophic-autotrophic denitrification chamber and an aerobic membrane separation chamber. Low concentrated organic sewage is introduced into anaerobic fermentation electron generation chamber; then, particulate and partly dissolved organic substances are intercepted and absorbed by carrier materials; and extracellular currents generated by microorganism reaction are used in following autotrophic denitrification processing. Micro-/ultra-membrane separation processing is used to improve operation load and solid-liquid separation effect of sewage treatment and thereby effluent could meet the high recycling standards. The directed electron flow is regulated and controlled to enhance nutrients' removal and to reduce sludge yield and fouling rate of membrane. The sewage treatment could efficiently treat low concentrated organic sewage at normal temperature (>15° C.) and dramatically decrease energy consumption.
