摘要

钢渣、矿渣、气化粉煤灰等固体废弃物具有潜在活性,可用于危险废物的无害化处置,实现以废治废的目的。选取矿渣基胶凝材料、铝酸盐水泥、矿渣-熟料-维生素C、赤泥-煤矸石地聚物、钢渣-气化粉煤灰地聚物,建立了飞灰无害化处置方案的生命周期模型。结果表明:人体健康影响是固废基材料固化技术的主要环境影响类别,化工原料是造成环境影响的主要原因,机械力化学激发方式环境影响最小。地聚物材料体系固化技术因大量碱激发剂使用造成的环境影响最大,矿渣-熟料-维生素C固化技术的环境影响最小。因此,调整固废基材料的激发方式并降低激发剂与外加剂的用量是减少人体毒性的必要途径。

Abstract

Industrial solid wastes, such as steel slag, blast furnace slag (BFS), and gasified fly ash, possess inherent reactive properties that can be utilized for detoxifying hazardous waste, thereby facilitating waste remediation through waste-derived solutions. In this study we selected a range of materials, including BFS-based cementitious materials, aluminate cement, BFS-clinker-vitamin C composites, red mud-coal gangue geopolymers, and steel slag-gasified fly ash geopolymers, to develop a life cycle model dedicated to the solidification/stabilization (S/S) of municipal solid waste incineration (MSWI) fly ash. Results indicate that: 1)the primary environmental impact of solid waste-based S/S technologies is on human health, with industrial chemical inputs being the main contributors. 2) Among the various activation methods examined, mechanochemical activation exhibited the least environmental impact. However, the environmental impact of geopolymer systems, particularly due to the extensive use of alkaline activators, was found to be the most significant. 3) In contrast, the BFS-clinker-vitamin C S/S method demonstrated the lowest environmental impact. Therefore, optimizing activation methods for solid waste-based materials and reducing the use of activators and additives are crucial to minimizing toxicological risks to human health.

Fly ash is a hazardous byproduct of municipal solid waste incineration (MSWI). Cementitious material that is based on ground-granulated blast furnace slag (GGBFS) has been tested and proposed as a binder to stabilize Pb, Cd, and Zn in MSWI fly ash (FA). Cr, however, still easily leaches from MSWI FA. Different reagents, such as ascorbic acid (VC), NaAlO, and trisodium salt nonahydrate, were investigated as potential Cr stabilizers. The results of the toxicity characteristic leaching procedure (TCLP) showed that VC significantly improved the stabilization of Cr via the reduction of Cr(VI) to Cr(III). VC, however, could interfere with the hydration process. Most available Cr was transformed into stable Cr forms at the optimum VC content of 2 wt%. Cr leaching was strongly pH dependent and could be represented by a quintic polynomial model. The results of X-ray diffraction and scanning electron microscopy-energy dispersive analysis revealed that hollow spheres in raw FA were partially filled with hydration products, resulting in the dense and homogeneous microstructure of the solidified samples. The crystal structures of C-S-H and ettringite retained Zn and Cr ions. In summary, GGBFS-based cementitious material with the low addition of 2 wt% VC effectively immobilizes Cr-bearing MSWI FA.Copyright © 2017. Published by Elsevier Ltd.

This study deals with the use of fly ash as a starting material for geopolymeric matrices. The leachable concentrations of geopolymers were compared with those of the starting fly ash to evaluate the retention of potentially harmful elements within the geopolymer matrix. Geopolymer matrices give rise to a leaching scenario characterised by a highly alkaline environment, which inhibits the leaching of heavy metals but may enhance the mobilization of certain oxyanionic species. Thus, fly ash-based geopolymers were found to immobilize a number of trace pollutants such as Be, Bi, Cd, Co, Cr, Cu, Nb, Ni, Pb, Sn, Th, U, Y, Zr and rare earth elements. However, the leachable levels of elements occurring in their oxyanionic form such as As, B, Mo, Se, V and W were increased after geopolymerization. This suggests that an optimal dosage, synthesis and curing conditions are essential in order to obtain a long-term stable final product that ensures an efficient physical encapsulation.
