A wastewater treatment technology device for nickel-containing wastewater

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment technical device for nickel-containing wastewater. Background technique [0002] Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and achieve wastewater recovery and reuse, making full use of water resources. [0003] In the existing technology, especially for the field of wastewater treatment containing heavy metal ions such as nickel ions, when the wastewater is treated, heavy metal ions such as nickel ions are often recovered, and heavy metal ions such as nickel ions are often mixed with a large amount of flocculation. The content of heavy metal ions such as nickel ions collected is low, and the device for recovering heavy metal ions such as nickel ions is easily blocked by flocs and solid particle waste in wastewater during long-term use, thereby reducing ...
