Cooperative treatment and oriented application method for waste incineration fly ash and industrial waste alkali liquor
The invention belongs to the field of harmless treatment and resource utilization of waste incineration fly ash, and relates to a waste incineration fly ash and industrial waste lye co-treatment and oriented application method, which comprises the following steps: S1, activating hazardous wastes to form an activated product; s2, performing geopolymerization chemical treatment on the activated product to form a geopolymer; s3, the geopolymer is used for preparing artificial soil, and resource utilization is carried out. Through activation treatment, silicon, aluminum, calcium, heavy metals, ash and other functional elements and effective components in the fly ash are activated and released and are used as raw materials, so that the problems of low fly ash utilization rate and low compressive strength of the obtained geopolymer in the existing fly ash geopolymer solidification and stabilization technology are solved; therefore, the prepared artificial soil can be applied to various scenes such as roads, garbage heap covering, protection facilities, building materials, tailing pond/pit restoration, ocean protection and ecological restoration.
本发明属于垃圾焚烧飞灰的无害化处置及资源化利用领域，涉及一种垃圾焚烧飞灰与工业废碱液协同处置及定向应用方法，包括如下步骤：S1对危险废物进行激活处理，形成激活产物；S2将所述激活产物进行地聚合化学处理，形成地聚合体；S3将所述地聚合体用于制备人造土，进行资源化利用。通过激活处理，将飞灰中的硅、铝、钙，以及重金属、灰分等功能元素和有效成分激活释放出来，并作为原材料加以利用，解决现有飞灰地聚合固化稳定化技术中飞灰利用率低、以及得到的地聚合物抗压强度低的问题，从而实现制备的人造土在道路、垃圾堆体覆盖、防护设施、建筑材料、尾矿库/矿坑修复、海洋防护与生态修复等多种场景中进行应用。
