Wastewater treatment technical device for nickel-containing wastewater

Abstract

The invention relates to a wastewater treatment technical device for nickel-containing wastewater, which comprises a purification cylinder and a cylinder cover, four sets of limiting blocks are annularly arranged on the upper end face of the purification cylinder at equal intervals, and four sets of limiting rods are annularly and fixedly connected to the ground of the cylinder cover at equal intervals; a blocky heavy metal adsorbent above the bottom of an I-shaped plate is slowly dissolved by water on the outer surface and moves up and down along with the up-down movement of the I-shaped plate, so that heavy metal particles dissolved on the outer surface of the blocky heavy metal adsorbent are rapidly diffused outwards under the agitation of the water, and heavy metal ions such as nickel ions in the water are adsorbed; and finally, the water falls on the upper surface of a first soft sheet through the filter holes of the I-shaped plate, the water flows out from the gap between the first soft sheet and the purification bin and leaves the device through the water outlet, and the heavy metal adsorbent particles adsorbing the heavy metal ions such as nickel ions are slowly gathered on the first soft sheet, so that the collection of the heavy metal ions such as nickel ions is completed.

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 ...
