Problems solved by technology

[0003] The current wastewater purifiers take a long time to complex and precipitate with heavy metal ions after being put into wastewater, the speed of water quality recovery is very slow, and the purification efficiency is low
For this reason, it is necessary to find an efficient method for purifying waste water to solve the problem that the speed of purifying waste water by metal purifiers for waste water in the prior art is too slow

Abstract

The invention relates to the field of wastewater purification, in particular to a wastewater metal scavenger. The wastewater metal scavenger is of a core-shell structure, and can quickly complex, gather and settle down heavy metal ions in wastewater. A preparation method comprises the following steps: mixing and stirring raw materials, performing spray granulation, spraying slurry to particles toform a wrap layer, and performing thermal treatment to obtain the wastewater metal scavenger. The wastewater metal scavenger disclosed by the invention can efficiently purify water and quickly realizeclarification of the water.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a metal purifier for waste water. Background technique [0002] Heavy metal wastewater (containing chromium, cadmium, copper, mercury, nickel, zinc and other heavy metal ions) produced in industrial production processes such as mining and metallurgy, machinery manufacturing, chemical industry, electronics, and instrumentation is the most serious water pollution and the most harmful industry to humans. One of the waste water, which contains a large amount of heavy metal ions, the pollution of the environment, especially rivers, due to excessive heavy metals is extremely serious, and has endangered human life. [0003] The current wastewater purifiers take a long time to complex and precipitate with heavy metal ions after being put into wastewater, the speed of water quality recovery is very slow, and the purification efficiency is low. For this reason, it is necessary to find...
