Method for preparing ceramsite adsorption material by coupling gasification slag with biochar
The invention relates to a method for preparing a ceramsite adsorbing material by coupling gasified slag with biochar, and belongs to the technical field of solid waste recycling. Comprising the following steps: step S1, preparing the following raw materials in parts by weight: 68-72 parts of coal gasification slag, 9-12 parts of cement, 8-10 parts of sodium silicate water glass, 6-8 parts of expanded perlite, 14-20 parts of functionalized biochar, 130-150 parts of modified liquid and 0.1-0.2 part of an initiator; s2, preparing a molded ceramsite rough blank; s3, modifying with a modifier; functional biochar and a modifier are added, the functional biochar contains hydroxyl, ester groups, acylamino, benzene rings and epoxy biochar structures, the functional biochar can be chelated with heavy metal cations and can also be chemically crosslinked with a modified liquid to form a three-dimensional intercommunicated net structure, and through the combined action of the functional biochar and the modified liquid, the heavy metal ions in the heavy metal ions can be removed, so that the heavy metal ions in the heavy metal ions can be removed, and the heavy metal ions in the heavy metal ions can be removed. The adsorption capacity of the ceramsite adsorption material and the chelation performance on metal ions are improved.
本发明涉及一种气化渣耦合生物炭制备陶粒吸附材料的方法，属于固体废物资源化技术领域，包括以下步骤：步骤S1、准备以下重量份原料：68‑72份煤气化渣、9‑12份水泥、8‑10份硅酸钠水玻璃、6‑8份膨胀珍珠岩、14‑20份功能化生物炭、130‑150份改性液和0.1‑0.2份引发剂；步骤S2、制备成型陶粒粗胚；步骤S3、改性剂改性；本发明加入了功能化生物炭和改性剂，功能化生物炭中含有羟基、酯基、酰胺基、苯环和环氧基生物炭结构，不仅能与重金属阳离子发生螯合，而且能与改性液发生化学交联，形成三维互通的网状结构，通过它们的共同作用，提高了陶粒吸附材料的吸附容量和对金属离子的螯合性能。
