Abstract
The invention discloses a phosphorus removal filler. The phosphorus removal filler comprises, by weight, 40%-60% of fly ash, 20%-40% of cement, 10%-20% of quicklime, 1%-3% of gypsum, 2%-8% of amino functional high-polymer composite materials and the balance 70%-90% sodium hydroxide solution. A method for preparing the phosphorus removal filler includes uniformly mixing the fly ash, the cement, the quicklime, the gypsum and the amino functional high-polymer composite materials with one another to obtain first mixtures; adding the 70%-90% sodium hydroxide solution into the first mixtures, stirring the first mixtures and the 70%-90% sodium hydroxide solution and uniformly mixing the first mixtures and the 70%-90% sodium hydroxide solution with one another to obtain second mixtures; artificially manufacturing small spheres with the diameters of 5-8 mm from the second mixtures or manufacturing small spheres with the diameters of 5-8 mm from the second mixtures by the aid of a pill manufacturing machine; naturally drying the small spheres by the aid of air for 24 hours; curing the small spheres by the aid of steam at the temperature of 40 DEG C for 2 hours; heating the small spheres until the temperatures of the small spheres are increased by 10 DEG C at intervals of 30 min; curing the small spheres for 12 hours after the temperatures of the small spheres are increased and reach 80 DEG C to obtain the phosphorus removal filler. The phosphorus removal filler and the method have the advantages that the phosphorus removal filler is low in production cost and high in pollutant removal capacity, and phosphorus removal effects of the phosphorus removal filler are superior to phosphorus removal effects of other common phosphorus removal fillers by 10%.
