An electrochemical membrane module for selectively removing pollutants and a preparation method thereof are provided. A Ti/SnO.sub.2—Sb substrate electrode is coated with a MI—TiO.sub.2 sol-gel by means of a dip-coating method, and then sintered to obtain a molecular imprinting type Ti/MI—TiO.sub.2/SnO.sub.2—Sb coated electrode; the coated electrode is adhered to a ceramic micro-filtration membrane using epoxy resin glue to obtain a Ti/MI—TiO.sub.2/SnO.sub.2—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.

An electrolytic reactor and process for decontaminating wastewater containing emerging contaminants, such as medicament residues or per- and polyfluoroalkyl substances (PFAS) are disclosed. The contaminated wastewater is circulated through one or several reactors for electro-oxidizing and degrading the contaminants. Each reactor comprises an enclosure, an electrode assembly comprising first and second current distribution circuits, a first group of N electrodes connected to the first current distribution circuit, and a second group of N electrodes connected to the second current distribution circuit. According to the polarity of the current provided to the electrodes, the electrodes of the first group form anodes whereas the electrodes of the second group forms cathodes, and vice versa. The electrodes are preferably dimensionally stable anodes (DSA). The reactor and process described herein allow removal of multiple emerging contaminants simultaneously, in addition to reducing the carbon footprint through lower power consumption.

The embodiments of the present disclosure provide an electrode plate, an electrolysis apparatus, and a laundry treatment device. Multiple through holes penetrating the electrode plate in the thickness direction of the electrode plate are formed in the electrode plate. The density of the through holes in the electrode plate is 1-10/cm.sup.2. According to the electrode plate in the embodiments of the present disclosure, on the one hand, because the density of surface charge at the junction of the inner wall of the through hole and the surface of the electrode plate is larger, and the electric field intensity nearby is higher, the electrolysis efficiency can be greatly improved, more active substances such as hydroxyl radicals and active chlorine can be generated, and more microbubbles can also be generated, which can improve the sterilization, cross color prevention and washing effects.

The method for forming a water sterilization electrode includes heating a conductive medium to an elevated temperature in a heating apparatus. The method further includes growing oxide nanostructures on the conductive medium at the elevated temperature by supplying one or more oxidizing gases to the heating apparatus. The method further includes ramping down from the elevated temperature at 2-30° C./min to a room temperature to form the water sterilization electrode having the oxide nanostructures on the conductive medium.

An illustrative aqueous ozone sanitizing system for body part, tissue, and instrument sanitizing, including hand rinsing and sanitizing includes a sanitizing chamber, spray devices configured to simultaneously irrigate the entire left and right hand of a user, at least two aqueous ozone generators each fluidly coupled to a subset of the spray devices, and a housing for the sanitizing chamber having an opening for guiding the user's hand orientation and position into the sanitizing chamber.

An electrolytic reactor for the electrolytic treatment of a fluid is disclosed. The reactor comprises an electrolytic chamber, an electrode cartridge comprising an electrode assembly longitudinally extending from a crown section configured to operatively seal the electrolytic chamber when the electrode assembly is inserted in the electrolytic chamber; an inlet extending perpendicularly to a vertical longitudinal axis defined by the electrolytic chamber; and an outlet extending through the crown section along the vertical longitudinal axis defined by the electrolytic chamber, the outlet being configured to be in fluid communication with the electrolytic chamber when the electrolytic chamber is sealed by the crown section. Advantageouslly, by having the outlet extending upwardly above the electrodes, any dead zone typically found on electrodes at the level of the outlet are eliminated, increaing as such the useful surface area of the electrodes spanning the entire length of the electrolytic chamber.
