Preparation process and method of steel slag modified sludge adsorption filler
The invention relates to a preparation process and method of a steel slag modified sludge adsorption filler, and belongs to the technical field of preparation of pollutant emission reduction materials. The method comprises the following steps: by taking steel slag and sludge as raw materials, carrying out drying, crushing, bonding and pore-forming processes, adding a certain amount of materials to enhance the strength and performance of the raw materials, then granulating to obtain raw material balls, and then drying, calcining and cooling the raw material balls to obtain the modified ceramsite. The invention relates to a preparation process and a preparation method of a steel slag modified sludge-based VOCs (Volatile Organic Compounds) adsorption filler, and aims to provide a preparation process and a preparation method which are used for modifying sludge through steel slag and can be used for directionally modifying the chemical function of ceramsite and effectively improving the chemical adsorption performance of the ceramsite. As the steel slag, the sludge and the conventional clay have similar sintering characteristics, compared with the traditional ceramsite preparation, the consumption of the clay is saved.
本发明涉及一种钢渣改性污泥吸附填料的制备工艺及方法，属于污染物减排材料制备技术领域。以钢渣、污泥为原料，通过干燥、破碎、粘结、造孔工艺，并通过一定的材料添加增强其强度及性能，然后造粒获得生料球，随后将原料球烘干、煅烧、冷却工艺获得改性陶粒。本发明涉及的钢渣改性污泥基VOCs吸附填料的制备工艺及方法，目的就是通过钢渣对污泥进行改性提供一种对陶粒化学功能进行定向修饰可以有效提高陶粒的化学吸附性能的制备工艺及方法，由于钢渣、污泥和常规黏土具有相似的烧结特性，相较于传统的陶粒制备节约了黏土的消耗。
