Description

Technical Field

[0001] The utility model relates to the technical field related to wastewater treatment technology, and in particular to a nickel removal device. Background Art

[0002] Nickel is an essential element for the human body, but the demand is very small. Once it exceeds the standard, it will endanger human health. Nickel damages human liver and cardiopulmonary function, and causes severe dermatitis and skin allergies. In 2017, the World Health Organization's International Agency for Research on Cancer announced that nickel compounds are on the Class 1 carcinogen list. Non-ferrous anodizing is a commonly used surface treatment technology, which is mainly used for corrosion protection and aesthetic improvement of metal materials. The process flow of non-ferrous anodizing mainly includes four steps: pretreatment, anodizing, sealing treatment and coloring treatment. Sealing treatment is to seal the oxide film after it is formed to improve the sealing and corrosion resistance of the oxide film. Commonly used sealing methods include nickel sealing and cadmium sealing. The nickel element pollution concentration in the wastewater is relatively high. If it is not treated or cannot meet the standard, Discharge not only harms the environment but also harms human health. Nickel-containing wastewater on the market is usually treated by chemical precipitation. The workshop wastewater flows into the regulating tank by gravity, is homogenized and equalized, and is lifted to the pH adjustment tank by a lifting pump. Under strong alkaline conditions, nickel forms nickel hydroxide precipitation and is removed. However, 70%-80% can be removed by adjusting the pH to strong alkaline conditions using liquid alkali / lime. After that, the wastewater is subjected to nickel removal-coagulation-flocculation-precipitation-salad-ultrafiltration-PH adjustment. Although the nickel-containing wastewater can be treated, the wastewater is discharged through the ultrafiltration system after two coagulation and flocculation. The treatment method is relatively simple and the operation is cumbersome, which increases the cost of adding chemicals and thus increases the cost of sewage treatment. Therefore, a nickel removal device is particularly needed.

[0003] However, most of the existing nickel removal devices do not have multiple processing and low-cost processing when in use, and consume more resources. The filtering effect is not very stable and requires multiple filtrations to filter cleanly. Utility Model Content
