Embodiment 1

[0017] In sewage with chromaticity (dilution multiple) of 80 and lead content of 7mg / L, an aluminum-zinc alloy electrode reactor is used for treatment, in which the aluminum content of the aluminum-zinc alloy electrode is 85%, and the zinc content is 15%. The chromaticity of the water sample is <20, which is higher than the national first-class discharge standard, and the lead content is 0.05mg / L, which is higher than the national reuse water standard of 0.5mg / L. It has been verified that the service time of aluminum-zinc electrodes is 3.5 times that of ordinary aluminum electrodes.

Embodiment 2

[0019] The wastewater with coliform content > 10000 / L is treated with an aluminum-copper alloy electrode reactor, in which the aluminum content of the aluminum-coli alloy electrode is 92%, and the copper content is 8%. The coliform content after treatment is zero. It has been verified that the service time of aluminum-zinc electrodes is 2.8 times that of ordinary aluminum electrodes.

Embodiment 3

[0021] The wastewater with high content of blue-green algae is treated with an aluminum-copper alloy electrode reactor. The aluminum content of the aluminum-copper alloy electrode is 95%, and the copper content is 5%. After treatment, the water quality is clear and transparent, and the chroma ( Dilution factor) is <15. It has been verified that the service time of aluminum-zinc electrodes is 2.3 times that of ordinary aluminum electrodes.

Abstract

The invention discloses a soluble aluminum electrode doped with copper zinc. The soluble electrode is composed of main body metal and doping metal, the main body metal is aluminum, the doping metal is copper or zinc. The soluble electrode comprises the following components by weight percentage: 80 percent to 95 percent of aluminum, 5 percent to 20 percent of zinc or 90 percent to 97 percent of aluminum, and 3 percent to 10 percent of copper. The soluble zinc aluminum binary alloy electrode is made by the process of casting, and the soluble aluminum copper electrode is made by the process of extrusion. The invention further provides an electrochemical water treatment method of the soluble aluminum electrode doped with copper zinc, according to the method, the soluble aluminum electrode doped with copper and zinc is taken as the positive pole, and other soluble and un-soluble electrodes are taken as the negative pole. The method provided by the invention has the advantages of high efficiency, can efficiently remove lead, germ and algae in waste water, so as to meet the requirement of increasingly strict sewage discharge standard, has long residual action, and can effectively decrease the wastage of soluble aluminum electrode and prolong the service time of the electrode.

Description

technical field [0001] The invention relates to the technical field of electrochemical water treatment, in particular to a soluble aluminum electrode doped with copper and zinc and a method for electrochemical water treatment thereof. Background technique [0002] Electrochemical water treatment is to use the principle of electrolysis to electrochemically treat water bodies, and to separate various substances in water that affect water quality standards through oxidation-reduction, electric force, electron action, electrode chemical reaction, electric floatation, electric flocculation, and electric excitation resonance. . The device using the principle of electrochemical water treatment technology can uniformly act on a large area of ​​special chemical electric energy inside the water body, stimulate the resonance of various particles in the water body, destabilize the aqueous solution, separate the solute and solvent, and achieve the purpose of purifying the water body. ...
