The invention relates to a fixed sterile drinking water storage device, belonging to the technical field of domestic drinking water quality advanced treatment. The drinking water storage device comprises at least one pair of negative and positive electrodes, an electrolysis power source and a water container, wherein a water-permeable diaphragm prepared from a non-conductive material is arranged between the negative electrode and positive electrode in pair; the water-permeable diaphragm is provided with water-permeable micropores with uniform pore size; the top of the water container is provided with a window; the water-permeable diaphragm is completely covered on the window; the negative electrode is arranged on the bottom in the water container; and the positive electrode is arranged outside the window on the top of the water container. When in use, the negative electrode contacts water in the water container, and the positive electrode only contacts the water container through the permeated water of the water-permeable diaphragm. The drinking water storage device can generate fewer toxic byproducts while degrading organic matters in the home terminal drinking water in the water container, and the toxic byproducts can not enter the home terminal drinking water.

The invention discloses a reactor for filtering PAHs (polycyclic aromatic hydrocarbons) in waste gas from composite electrocatalytic oxidation treatment. The reactor comprises a housing, wherein the housing is made of quartz glass or ceramics, a gas inlet is arranged at one end of the housing, and a gas outlet is arranged at the other end of the housing; a metal conductive material is wrapped on the outer wall surface of the housing, and the metal conductive material is grounded as an outer electrode for dielectric barrier discharge; a porous metal reaction body is arranged right in the middle in the housing, and the porous metal reaction body is connected with an alternating current power supply as an inner electrode for the dielectric barrier discharge; the porous metal reaction body isformed by sintering stainless steel powder and loaded with a metal oxide catalyst; the end close to the gas inlet, of the porous metal reaction body is closed, and the other end close to the gas outlet, of the porous metal reaction body is open and communicated with the gas outlet; and a certain gap is left between the housing and the porous metal reaction body for forming a dielectric barrier discharge gap, and the dielectric barrier discharge gap is communicated with the gas inlet. The reactor can realize high-efficient degradation of the gas-phase and the solid-phase PAHs.

The invention relates to a water purifier.The water purifier comprises an electrolysis unit and a membrane filtration unit.The electrolysis unit comprises at least one pair of anodic electrode and cathodic electrode, an electrolysis power source supplying power to the anodic electrodes and the cathodic electrodes and a water tank.A permeable diaphragm made of a non-conductive material is arranged between the anodic electrode and the cathodic electrode in each pair.The water tank is provided with a first water inlet and a first water outlet.Each permeable diaphragm is provided with permeable micropores with a uniform aperture.The side wall of the water tank is provided with windows.The permeable diaphragms are fully laid on the windows.The cathodic electrodes are arranged in the water tank, and the anodic electrodes are arranged outside the water tank.A porous adsorbing material is arranged in the water tank.The first water outlet is formed in the porous adsorbing material.The membrane filtration unit is provided with a second water inlet and a second water outlet.The first water outlet is communicated with the second water inlet.Compared with an existing physical filtration water purifier, the water purifier is reliable in operation and long in service life.

The invention relates to a desk type simple water dispenser which comprises an electrolysis unit and a membrane filter unit. The electrolysis unit comprises at least a pair of positive electrode and negative electrode, an electrolysis power supply and a water tank. The electrolysis power supply supplies power for the positive electrode and the negative electrode. A water-permeable diaphragm made of a non-conductive material is arranged between each pair of negative electrode and positive electrode; the water tank is provided with a first water inlet and a first water outlet, the positive electrode is separated from the water tank by the water-permeable diaphragm, and the negative electrode is disposed in the water tank. The membrane unit is provided with a second water inlet and a second water outlet which are communicated with each other. During use of the desk type simple water dispenser, each negative electrode is in direct contact with water stored in the water tank, each positive electrode is in contact with the water tank via water permeated from the water-permeable diaphragms only, and thus a water film is sandwiched between the positive electrode and the water-permeable diaphragm. The water dispenser has the advantages that contaminant in source water can be removed effectively, bacteria in source water can be inactivated completely, toxic and side products are avoided, and the water dispenser is reliable in operation and long in service life.
