Biochar-modified waste incineration fly ash-based carbon sequestration artificial aggregate and preparation method thereof
The invention discloses a biochar-modified waste incineration fly ash-based carbon sequestration artificial aggregate and a preparation method thereof, a chemical component complementation mechanism among waste incineration fly ash, granulated blast furnace slag and desulfurized gypsum is utilized, porous and light biochar is doped, and the biochar-modified waste incineration fly ash-based carbon sequestration artificial aggregate is prepared through scientific formula design and reasonable process route optimization. The novel and low-carbon all-solid-waste-based light-weight high-strength artificial aggregate is prepared. According to the method, land resource occupation caused by landfill and potential secondary environmental pollution risks are greatly reduced, meanwhile, resource utilization of the three kinds of solid waste including the waste incineration fly ash, the granulated blast furnace slag and the desulfurized gypsum is achieved, and the solid waste is converted into the light and high-strength carbon sequestration artificial aggregate under the modification effect of the biochar; and the mining requirement on the natural gravel aggregate is further reduced.
本发明公开了一种生物炭改性的垃圾焚烧飞灰基固碳人造骨料及制备方法，利用垃圾焚烧飞灰、粒化高炉矿渣和脱硫石膏之间的化学成分互补机制，并掺入多孔、轻质的生物炭，通过科学的配方设计以及合理的工艺路线优化，制备出一种新型、低碳的全固废基轻质高强人造骨料。本发明大大降低了因填埋而导致的土地资源占用以及潜在的环境二次污染风险，同时实现了垃圾焚烧飞灰、粒化高炉矿渣和脱硫石膏三类固体废弃物的资源化利用，而在生物炭的改性作用下将其转化成轻质、高强的固碳人造骨料，进一步减少了对天然砂石骨料的开采需求。
