Preparation method of lanthanum-aluminum bimetal modified bentonite ceramsite for removing phosphorus from water body
The invention provides a preparation method of lanthanum-aluminum bimetal modified bentonite ceramsite for removing phosphorus from a water body, and relates to the technical field of preparation of phosphorus removal agents. The preparation method of the ceramsite comprises the following steps: firstly, preparing a lanthanum-aluminum mixed solution, then fully mixing bentonite powder, quicklime powder, anhydrous sodium carbonate and the lanthanum-aluminum mixed solution to prepare ceramic balls, drying, calcining, cooling and the like to prepare the lanthanum-aluminum bimetal modified bentonite ceramsite. The prepared ceramsite is high in adsorption capacity and can be subjected to an inner sphere complexation reaction with phosphorus in water, phosphorus is adsorbed to the surface of a solid, and the phosphorus removal effect is achieved.
本发明提供了一种水体除磷用的镧铝双金属改性膨润土陶粒的制备方法，涉及除磷剂制备技术领域。本发明所述陶粒的制备方法包括以下步骤：首先制备镧铝混合溶液，然后将膨润土粉、生石灰粉末、无水碳酸钠以及镧铝混合溶液充分混合后制成陶瓷球，经过干燥、煅烧、冷却等步骤制得镧铝双金属改性膨润土陶粒。本发明制备的陶粒吸附能力强，能与水中的磷发生内球络合反应，将磷吸附于固体表面，达到除磷的作用。
