Magnesium hydroxide modified diatomaceous earth: an efficient and environmentally friendly solution for phosphorus-containing wastewater treatment

With the acceleration of industrialization and urbanization, the problem of eutrophication of water bodies has become increasingly serious. Phosphate, as one of the main nutrients, has a particularly significant impact on the water environment. As a new type of phosphorus-containing sewage treatment material, magnesium hydroxide modified diatomite has attracted widespread attention due to its high efficiency and environmental friendliness.

Enhanced adsorption performance

Magnesium hydroxide modification significantly improves the adsorption capacity of diatomite. By enhancing electrostatic attraction, it improves the adsorption efficiency of phosphate and effectively removes phosphorus pollutants in water bodies. Optimization of buffering effect

Modified diatomaceous earth has good buffering properties and can adapt to wastewater environments with different pH values, simplifying the operation process and improving treatment efficiency.

Compared with traditional aluminum salt and iron salt dephosphorizers, magnesium hydroxide modified diatomaceous earth does not contain heavy metals, reduces secondary pollution to the environment, and is a green and environmentally friendly water treatment material. High adsorption capacity

Modified diatomaceous earth has a large specific surface area and high adsorption capacity, which can more effectively remove phosphorus from water and improve the sewage treatment effect.

Modified diatomite has good regeneration performance and can be recycled many times, which reduces the cost of sewage treatment and improves economic benefits. Simplified treatment steps

During the preparation process, diatomaceous earth is pretreated and modified, combined with magnesium hydroxide, and the modified material is obtained through mixing, reaction and filtration steps. In sewage treatment, it can be directly put into the aeration tank or outlet to remove phosphorus through physical and chemical effects. Actual application effect

Studies have shown that magnesium hydroxide modified diatomaceous earth performs well in actual water phosphorus removal applications, and can effectively reduce the phosphorus content in water and improve water quality. As an efficient and environmentally friendly phosphorus-containing sewage treatment material, magnesium hydroxide modified diatomaceous earth helps to improve the phosphorus removal efficiency of sewage treatment systems and protect the water environment. With the continuous maturity of technology and the widespread promotion of its application, it is expected to make greater contributions to water environment protection and sustainable development.
