The role of magnesium oxide in water / sewage treatment
Sewage treatment plays a role in magnesium oxide. Magnesium oxide can react with sewage to generate magnesium hydroxide. Powdery magnesium oxide reacts with sewage to first generate magnesium hydroxide, while magnesium oxide reacts with sewage to generate magnesium hydroxide. The harmful impurities in the sewage are treated away. The purpose of magnesium hydroxide is to be used as a neutralizing agent. Magnesium hydroxide is alkaline and has good adsorption performance. It can be used as acid-containing waste gas, wastewater treatment, waste liquid containing heavy metals and organic matter. Neutralizing agents such as treatment have been widely used in water treatment systems in recent years. In particular, heavy metals in sewage are more toxic, difficult to be metabolized in the environment, easy to be enriched by organisms and gradually expand along the biological chain, etc., the harm to the environment is more serious, the surface area of magnesium hydroxide is large, The adsorption capacity is strong, and the solubility product is larger than that of ordinary metals. Therefore, the treatment of heavy metal ions with magnesium hydroxide, in addition to adsorption, will also produce precipitates due to displacement. According to research, magnesium hydroxide can not only neutralize the acid in the wastewater, but also form a precipitate for Cu, Fe, Cr (111), Pb, Zn and other ions in the water, and be further removed by the adsorption of magnesium hydroxide. For the purpose of complete removal, Ni and Cd plasma can also be partially removed. The produced magnesium hydroxide water treatment agent has been used in sewage treatment systems in several cities at home and abroad, and it has formed a good reputation in the industry because of its stable product quality and good service.
