Embodiment Construction

[0051] Please refer to Figure 1 to Figure 7 As shown, it shows the specific structure of the electrocoagulation wastewater treatment device 10 of the preferred embodiment of the present invention. The electrocoagulation wastewater treatment device 10 is composed of multiple sections of pipelines 11 circuitously connected in series. Water inlet 12 is arranged, and water inlet valve 13 is installed at this water inlet 12 places. A water outlet 14 is provided on the final pipeline 112, and a pressurizing valve 15 is installed at the water outlet 14. A detection valve 16 is installed at the joint 114 of any section of pipeline 113 in the middle and its upper section of pipeline, and a dosing valve 17 is installed at the joint 114 of its next section of pipeline.

[0052] like Figure 2 to Figure 5 As shown, each section of tubing 11 includes an anode 115 and a cathode 116 for electrocatalysis. The cathode 116 is tubular, forming a lumen 1161 inside the cathode 116; the anode 1...

Abstract

The invention discloses an electric flocculation wastewater treatment electrode which comprises a tubular cathode and a rod-shaped or tubular anode, wherein a tubular cavity is formed inside the cathode; the anode is supported in the center of the tubular cavity of the cathode by a plurality of support frames; each support frame comprises an annular body and multiple supporting ribs; the anode penetrates through an annular ring formed by the annular body; and each supporting rib comes into contact with an inner wall surface of a cathode tube, and multiple water flow channels through which water flow can form vortex are formed between each supporting rib and the inner wall surface of the cathode tube. As an electrode of a sewage treatment device is directly made into a tube form, sewage can directly flow in the tubular cavity, and the sewage is electrolyzed while flowing; and moreover, by the water flow channels in the support frames, the water flowing through the channels forms vortex, so that liquid medicine is well mixed, the dissolubility is higher, and the treatment effect is better. In addition, a leakage-proof rubber tube seal is arranged outside the cathode, a closed reaction space is formed, the generated harmful gases do not escape, control is simple, and the reaction is complete.

Description

technical field [0001] The invention relates to the technology in the field of wastewater treatment, in particular to a new application of an electrocoagulation wastewater treatment electrode in wastewater treatment. Background technique [0002] At present, there are the following centralized traditional methods for the pre-treatment of electroplating heavy metal wastewater before reuse: [0003] 1. Precipitation method: that is, by adding chemicals to form metal oxide precipitation or metal oxide co-precipitation on the generated precipitate, so as to achieve the purpose of removing heavy metal ions. To a certain extent, this method has disadvantages such as difficulty in reaching the standard after treatment, slow sedimentation of sludge and difficulty in dehydration. [0004] 2. Adsorption method: through the exchange of metal ions with ions or functional groups in the adsorbent, they are adsorbed on the adsorbent and removed. The shortcomings of this method are: some ...
