Abstract

The invention provides a phosphorus removal material and a preparation method thereof. According to the phosphorus removal material, a phosphorus removal surface layer with the phosphorus removal effect coats a construction aggregate, phosphorus in water can be effectively removed by mixing the phosphorus removal material and phosphorus-containing sewage, and then the technical problems that in an existing phosphorus removal method is poor in phosphorus removal effect and secondary pollution is easily caused can be solved; the phosphorus removal material has the advantages that the phosphorus removal effect is good, the phosphorus removal efficiency is high and no secondary pollution is caused. Meanwhile, the invention further provides the preparation method of the phosphorus removal material. According to the method, after the phosphorus removal compound in the raw material and the construction aggregate are mixed and then broken and smashed to prepare the phosphorus removal material, the method has the advantage of being simple and convenient to implement, and the obtained phosphorus removal material has the advantages of being uniform in structure, good in phosphorus removal effect and the like.

Description

technical field [0001] The invention relates to the field of phosphorus removal, in particular to a phosphorus removal material and a preparation method thereof. Background technique [0002] With the continuous development of industrialization, people are increasingly using a series of phosphorus-containing chemical reagents such as phosphorus-containing pesticides and phosphorus-containing detergents. The use of these chemical reagents has increased food production and made people's lives cleaner. Bring us convenience. [0003] However, due to the excessive use of phosphorus-containing reagents and more and more discharges without treatment, the phosphorus content in water is increasing day by day. Excessive phosphorus content in water bodies will lead to eutrophication of water bodies and lead to a series of serious environmental consequences: aquatic organisms and microorganisms that depend on phosphorus growth in water bodies such as coastal areas, rivers, lakes, and s...
