Magnesium hydroxide is formed by reaction of magnesium oxide with water, and magnesium hydroxide is formed by reaction of magnesium oxide powder with sewage.
MgO+ H2O = Mg (OH)2, at the moment when magnesium oxide reacts with sewage to generate magnesium hydroxide, the harmful substance silicon and other impurities in sewage are disposed of by reaction.
As the magnesium hydroxide has the characteristics of buffering, great activity, strong adsorption capacity, non-corrosive, safe, non-toxic and harmless, and has been widely used in water treatment system in recent years
In particular, heavy metals in sewage cause more serious harm to the environment due to their characteristics such as high toxicity, difficulty in being metabolized in the environment, easy to be enriched by organisms and gradual expansion along the biological chain. Magnesium hydroxide has a large surface area, strong adsorption capacity, and a solubility product larger than that of general metals. Therefore, magnesium hydroxide is used to treat heavy metal ions. In addition to the adsorption, precipitates will be generated due to the displacement effect.
According to the research, magnesium hydroxide can not only neutralize the acid in wastewater, but also form precipitation on the ion of Cu, Fe, Cr (111), Pb and Zn in water, and further remove them through the adsorption of magnesium hydroxide, so as to achieve the purpose of complete removal, and partially remove the Ni and Cd etc.
