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.
