Modified cancrinite ceramsite capable of efficiently removing ammonia nitrogen and preparation method of modified cancrinite ceramsite
The invention provides modified cancrinite ceramsite capable of efficiently removing ammonia nitrogen and a preparation method of the modified cancrinite ceramsite. The modified cancrinite ceramsite comprises the following raw material components in percentage by mass: 40-90% of fly ash, 0-20% of rare earth tailings, 0-20% of blast furnace slag, 5-30% of a pore forming agent and 0-20% of an additive. The raw materials are solid wastes such as fly ash and rare earth tailings, so that high-valued utilization of the solid wastes and efficient and rapid adsorption of ammonia nitrogen can be realized; the modified cancrinite ceramsite prepared on the basis of the method is used for efficient adsorption of ammonia nitrogen in wastewater, treats waste with waste, and has great significance in high-value utilization of solid waste and water pollution treatment.
本发明提供了一种高效除氨氮的改性钙霞石陶粒及其制备方法，包括如下质量百分比的原料组分：粉煤灰40‑90％，稀土尾矿0‑20％，高炉渣0‑20％，造孔剂5‑30％，添加剂0‑20％。其原料为粉煤灰和稀土尾矿等固体废弃物，可以实现固体废弃物的高值化利用和对氨氮的高效快速吸附；基于本发明方法制备得到的改性钙霞石陶粒用于废水中氨氮的高效吸附，以废治废，对固废的高值化利用和水污染治理具有重大意义。
