Curing treatment method for waste incineration fly ash
The invention relates to the technical field of waste incineration fly ash treatment, in particular to a curing treatment method for waste incineration fly ash, which comprises the following steps: uniformly mixing cement and incineration fly ash to obtain a cement-fly ash mixture; dissolving the prepared nitrogen-doped carbon nanodots in mixing water, and uniformly mixing to obtain a nitrogen-doped carbon nanodot solution; and adding the nitrogen-doped carbon nanodot solution into the cement-fly ash mixture, and uniformly mixing to obtain the stable cement-fly ash solidified body. The method is simple and efficient to operate and low in preparation cost, heavy metals in the incineration fly ash can be greatly solidified, the leaching toxicity of the heavy metals is remarkably reduced, and environmental hazards are reduced.
本发明涉及垃圾焚烧飞灰处理技术领域，具体为一种用于垃圾焚烧飞灰的固化处理方法，包括以下步骤：将水泥和焚烧飞灰混合均匀得到水泥‑飞灰混合物；将制备的氮掺杂碳纳米点溶解于拌合水中，混合均匀，得到氮掺杂碳纳米点溶液；在所述的水泥‑飞灰混合物中加入氮掺杂碳纳米点溶液，混合均匀，得到稳定的水泥‑飞灰固化体。本方法操作简单高效，制备成本低，可大量固化焚烧飞灰中重金属，显著降低其浸出毒性，减少环境危害。
