Multi-source solid waste porous ceramsite for treating phenol-containing wastewater and preparation method of multi-source solid waste porous ceramsite
The invention provides multi-source solid waste porous ceramsite for treating phenol-containing wastewater and a preparation method of the multi-source solid waste porous ceramsite, and belongs to the technical field of solid waste resource utilization and wastewater treatment. The preparation method of the porous ceramsite comprises the following steps: S1, respectively drying and sieving the iron tailings, the vanadium extraction waste slag and the fly ash; s2, grinding the iron tailings, the vanadium extraction waste slag, the fly ash, the quick lime, the glass powder and the ammonium bicarbonate, and uniformly mixing; s3, adding deionized water, uniformly mixing, pressing into balls to obtain raw material balls, and putting the raw material balls into a microwave oven for low-temperature foaming; and S4, transferring the foamed pellets into a muffle furnace for sintering, carrying out heat preservation, and then carrying out furnace cooling to room temperature so as to obtain the multi-source solid waste porous ceramsite. The preparation method is simple and low in cost, multiple solid waste resources can be consumed at the same time, and the prepared porous ceramsite material is easy to recycle, not prone to agglomeration and high in degradation rate of phenol-containing wastewater and has great practical significance and market competitiveness.
本发明提供了一种处理含苯酚废水的多源固废多孔陶粒及其制备方法，属于固体废弃物资源化利用以及废水处理技术领域。所述多孔陶粒的制备方法为：S1、将铁尾矿、提钒弃渣和粉煤灰分别进行干燥和过筛；S2、将铁尾矿、提钒弃渣、粉煤灰、生石灰、玻璃粉和碳酸氢铵进行研磨，使其混合均匀；S3、加入去离子水，混合均匀后压制成球形，获得生料球，放入微波炉中进行低温发泡；S4、将发泡后的料球转移到马弗炉中进行烧结，保温后随炉冷却至室温，即得到所述多源固废多孔陶粒。本发明制备方法简单，成本低，可同时消纳多种固体废弃物资源，制备得到的多孔陶粒材料容易回收，不易团聚，对含苯酚废水降解率高，具有很大的现实意义和市场竞争力。
