The invention discloses a
wastewater treatment technology device for
nickel-containing
wastewater, which comprises a purification cylinder and a cylinder cover. The upper end surface of the purification cylinder is provided with four sets of limit blocks at equal intervals in a ring, and the ground of the cylinder cover is fixed at an equal interval in a ring. Four sets of limit rods are connected, and the block-shaped heavy
metal adsorbent above the bottom of the I-shaped plate is slowly dissolved by water, and moves up and down as the I-shaped plate moves up and down, thereby dissolving the block-shaped heavy
metal adsorbent on the outer surface. The heavy
metal particles are rapidly diffused outward by the agitation of water, thereby absorbing heavy metal ions such as
nickel ions in the water, and finally fall on the upper surface of the first film through the filter holes of the I-shaped plate, and the water flows from the gap between the first film and the purification chamber. The gap flows out and leaves the device through the water outlet, and the heavy metal adsorbent particles adsorbed with heavy metal ions such as
nickel ions slowly accumulate on the first film, thereby completing the collection of heavy metal ions such as
nickel ions.
