The invention discloses a manufacturing method of foamed glass with high phosphate adsorption performance. The manufacturing method comprises the following steps: crushing waste glass and grinding into glass powder; adding the foaming material A and the additive B into the glass powder, and fully mixing; carrying out compression molding on the mixed raw materials for manufacturing the foamed glass, and then firing to obtain the foamed glass, the fired foamed glass is shaped and then cooled; washing and drying the cooled foamed glass; cutting the foamed glass in the dry state; the foamed glass prepared in the invention can provide a material selection with high water purification performance and environmental protection for water purification, and compared with foamed glass produced by a traditional method, the foamed glass prepared by the formula and the method has greatly improved phosphate adsorption capacity, has good sewage purification potential, and is suitable for industrial production.
