Resource Utilization of Magnesium Oxide Desulfurization Wastewater: Analysis of the Benefits of Magnesium Building Materials Production
Under the current background of environmental protection and sustainable development, the resource utilization of magnesium oxide desulfurization wastewater has become a hot research field. By converting it into magnesium building materials products with commercial value, it not only solves the problem of environmental pollution, but also creates new economic growth points. This article will explore the benefit analysis of magnesium oxide desulfurization wastewater in the production of magnesium building materials.
Resource Utilization of Magnesium Oxide Desulfurization Wastewater
The wastewater generated during the magnesium oxide desulfurization process contains a large amount of magnesium sulfate (MgSO₄), which is an important raw material for the preparation of magnesium building materials. Through a series of chemical treatments, these wastewaters can be converted into high-value-added magnesium building materials products. For example, the reaction process of producing high-purity magnesium oxide by roasting and pyrolysis is as follows:
Mg(HCO3)2+2H2O=MgCO3⋅3H2O+CO2↑Mg(HCO3)2+2H2O=MgCO3⋅3H2O+CO2↑ 5(MgCO3⋅3H2O)→4MgCO3⋅Mg(OH)2⋅2H2O+12H2O+CO2↑5(MgCO3⋅3H2O)→4MgCO3⋅Mg(OH)2⋅2H2O+12H2O+CO2↑ 4MgCO3⋅Mg(OH)2⋅2H2O→5MgO+3H2O+4CO2↑4MgCO3⋅Mg(OH)2⋅2H2O→5MgO+3H2O+4CO2↑
Market potential of magnesium building materials
As a new type of environmentally friendly building material, magnesium building materials have the advantages of light weight, high strength, fire resistance, and sound insulation. They have broad application prospects in the fields of construction, transportation, aviation, etc. With the continuous growth of China's economy and the continuous advancement of infrastructure construction, the magnesium building materials industry has developed rapidly and market demand has continued to grow.
