Calcium carbonate is indispensable in the high-tech field!-2
Application in wastewater treatment
(1) Adsorption of organic matter
Calcium carbonate has excellent adsorption properties and can effectively absorb organic matter in wastewater, such as phenol and styrene. This characteristic not only reduces the impact of organic matter on other pollutants, but also significantly improves the quality of the water environment and achieves the purpose of purifying wastewater.
(2) Adsorption of heavy metal ions
Heavy metal ions such as cadmium and aluminum contained in wastewater not only pose a threat to the water environment, but also harm human health. Calcium carbonate can effectively adsorb these heavy metal ions and reduce their concentration, thereby reducing the risk of heavy metal pollution.
(3) Precipitated organic matter
Calcium carbonate can combine with organic matter in wastewater to form stable cluster precipitation, thereby removing organic pollutants. By precisely controlling the sedimentation conditions and speed, the content of organic matter in wastewater can be effectively reduced and the wastewater treatment effect optimized.
(4) Precipitation of heavy metal ions
Calcium carbonate can react with heavy metal ions in wastewater to form precipitates to achieve the purpose of removing heavy metals. This method has become one of the commonly used solutions in wastewater treatment due to its simple process and low cost.
