Embodiment 1

[0078] TiO with surface rich in metal Ir, Ru, Pd oxides 2 The sintered coated titanium alloy plate is used as the anode A of the micro-current catalytic electrolysis, the size is 0.8m×0.5m; the cathode material is the titanium alloy plate B of 0.8m×0.5m; the steel structure cantilever E fixed in parallel and fixed on the jacket nylon tube Above, the distance between adjacent electrodes is 8cm, see Figures (1) to (3).

[0079] The power of ultrasonic generating probe C is 1.5kw, and the direction of ultrasonic generation is perpendicular to the electrode arrangement direction, and is connected with the ultrasonic probe fixing ring H on the steel structure cantilever E and the moving rod D of the ultrasonic generating probe through the fixed rod G, see Figure (2 )~(5).

[0080] The conductivity of natural fresh water is generally between 500 and 1000 μS / cm, calculated using the median value of 800 μS / cm, and the resistance between the two electrodes R=1 / (800×10 -6 ×0.5×0.8×10 ...

Embodiment 2

[0092] Since it is impossible to accurately measure the killing efficiency of micro-current catalytic electrolysis on bacteria and algae in open water bodies, a small-volume simulation test is used to determine the killing efficiency of micro-current catalytic electrolysis on bacteria and algae in water bodies. The simulation test device is shown in Figure (6).

[0093] TiO with surface rich in metal Ir and Rh oxides 2 The sintered coated titanium alloy plate is used as the anode A of the micro-current catalytic electrolysis, with a size of 210mm×95mm; the cathode material is a titanium alloy plate B of 210mm×95mm; the electrode interval is 7.5mm, and there are 3 anodes and 4 cathodes fixed in parallel In a closed PVC tank, the two ends are attached to the wall of the PVC tank with cathode plates, and the lead wires are connected to the constant current DC generator J to form a micro-current catalytic electrolysis device I, which is passed through the pipeline and ( Greenforc...

Abstract

The invention discloses a combined water treatment technology and apparatus using electric current to electrolyze water, wherein the main body comprises a plurality of parallel de-greasing electrodes, ultrasonic generation probes, power suppliers and a control system, wherein the multiple anodes containing metals Pt, Ir, Ru, Rh, Pd and their oxides are employed to electrolyze the chlorine ions and water molecules in the water into substances with high oxidation activity, and oxidation action is proceeded with the cells, RNA, DNA of the bacteria and algae so as to make them inactivate and dye.

Description

field of invention [0001] The invention is a combined micro-current electrolysis water treatment technology and device, especially the micro-current electrolysis water treatment technology and device for killing cyanobacteria, which belongs to the category of environmental protection technology. Background technique [0002] Cyanobacteria (cyanobacteria) is also known as blue-green algae or blue-green algae (blue-green algae). Their nucleus structure has no nuclear membrane and nucleolus, belongs to prokaryotic organisms, does not undergo mitosis, and their cell walls are similar to bacteria, composed of peptidoglycan, and Gram staining is negative, so they belong to prokaryotic microorganisms. [0003] Cyanobacteria are single-celled organisms, and the individual is larger than bacteria, generally with a diameter or width of 3-15 μm. However, cyanobacteria rarely live as single individuals, and usually gather together after dividing to form filamentous or unicellular group...
