Multi-source solid waste porous ceramsite and application thereof in phenol wastewater treatment
The invention provides multi-source solid waste porous ceramsite and application thereof in treatment of phenolic wastewater, and belongs to the technical field of solid waste resource utilization and wastewater treatment. The porous ceramsite comprises titanium-containing blast furnace slag, coal gangue and fly ash, the mass percent of the titanium-containing blast furnace slag, the mass percent of the coal gangue and the mass percent of the fly ash are set to be x, y and z respectively, x + y + z = 1, and the following relational expression is met: 0.53 < = 0.2489 x + 0.631 y + 0.4775 z < = 0.79; 0.1394 x + 0.2116 y + 0.3142 z is greater than or equal to 0.1 and less than or equal to 0.25; 0.079 < = 0.5928 x + 0.1528 y + 0.1716 z < = 0.24; the crystalline phase composition of the porous ceramsite is quartz SiO2, perovskite CaTiO3, and pyroxene Ca (Mg, Fe, Al) (Si, Al) 2O6. The porous ceramsite material prepared by the invention is low in cost, can simultaneously utilize various solid waste resources, has high degradation rate on phenol in wastewater, and can meet the requirements of industrial production and treatment.
本发明提供了一种多源固废多孔陶粒及处理苯酚废水的应用，属于固体废弃物资源化利用以及废水处理技术领域。所述多孔陶粒包括含钛高炉渣，煤矸石和粉煤灰，设含钛高炉渣、煤矸石、粉煤灰的质量百分比分别为x、y、z，其中x+y+z＝1，并满足下列关系式：0.53≤0.2489x+0.631y+0.4775z≤0.79；0.1≤0.1394x+0.2116y+0.3142z≤0.25；0.079≤0.5928x+0.1528y+0.1716z≤0.24；所述多孔陶粒的晶相组成为石英SiO2、钙钛矿CaTiO3、辉石Ca(Mg,Fe,Al)(Si,Al)2O6。本发明制备得到的多孔陶粒材料成本低廉，可同时利用多种固体废弃物资源，对废水中的苯酚降解率高，可适应工业化生产和处理的需要。
