一种利用固体废弃物钛石膏制备硫酸钙复合肥的方法研究

Method for Preparing Calcium Sulfate Compound Fertilizer by Utilizing Solid Waste Titanium Gypsum

采用钛石膏复配硫酸铵、磷酸一铵、腐植酸钾等其他肥料,进行硫酸钙复合肥的复配和造粒,充分利用二次资源,回用于土壤,完全可以满足土壤钙和硫的需求,并且钛石膏生成的硫酸钙颗粒细小,均匀,具有良好的保湿和气孔,利于土壤水分、温度和空气的保持等优势,具有广泛的发展前景。

Using titanium gypsum mixed ammonium sulfate,phosphoric acid ammonium,potassium humate and other fertilizer,calcium sulfate compound fertilizer mixing and granulating,make full use of secondary resources,back to soil,can fully meet the needs of soil calcium and sulfur and titanium gypsum formation of calcium sulphate particles,fine,uniform,with good moisture and porosity,conducive to soil moisture,air temperature and keep the advantage,with broad prospects for development.
