At present, the method for removing phosphorus in sewage mainly comprises a biological method and a chemical method. The biological phosphorus removal process is complex, and the effluent stability is poor; although the chemical phosphorus removal method has good treatment effect, most of phosphorus removal (medicament) materials are industrial products such as lime, aluminum salt, ferric salt, ferrous salt, magnesium salt and the like, and the bottleneck of the method in practical production application is caused by higher cost of the phosphorus removal medicament and larger sludge amount. The existing research shows that the development of the high-efficiency phosphorus removal material with strong phosphorus adsorption capacity, certain strength and chemical stability, small water flow resistance and good economic benefit is applied to the chemical phosphorus removal process of various sewage (wastewater) to enrich and separate the phosphorus in the sewage, and the material is an important means for ensuring the phosphorus removal effect of the sewage and realizing the recycling of phosphorus resources. In addition, how to remove color while effectively removing phosphorus from sewage (wastewater) and black and odorous water is one of the hot topics studied in recent years.
