工业危废中铅、铬、镉的迁移转化对生态环境造成严重危害，成为亟待解决的环境问题。高温陶瓷烧结技术在稳定重金属的同时将工业废物资源化利用，成为当前工业危废处理的最有效手段之一。目前研究主要集中于陶瓷产品性能测试，并没有明确重金属在陶瓷基体中稳定化的关键机理，同时高温烧结因能耗过高也限制了该技术的推广。因此，不仅需要建立低能耗烧结陶瓷体系，并且需要对该体系中重金属的稳定化机理进行系统的理论研究。本项目选择含铅、铬、镉的工业危废，加入不同种类及配比的陶瓷原材料形成低温烧结陶瓷体系，结合X射线衍射精修定量技术，解析铅、铬、镉赋存相的晶体结构，定量铅、铬、镉的稳定化效率，明确铅、铬、镉在赋存相中的分配行为，揭示烧结过程中铅、铬、镉的稳定化机理。本项目的实施，将为陶瓷烧结技术在电镀污泥、电池工业污泥、铬渣等重金属工业废物的推广提供理论基础，为固体废物协同处置及可持续资源化利用提供科学依据。

The accumulation of metal-laden industrial hazardous waste has become a major environmental concern due to the release of hazardous Pb, Cr, and Cd to the environment without proper treatment. Nowadays, ceramic technology has been accepted as one of the most effective methods for heavy metal stabilization, and the metal-laden sludge can be beneficially blended into a variety of ceramic products, such as bricks, tiles and refractory aggregates. Current policy for metal-bearing waste focuses on developing its potential to be recycled into usable products as a waste-to-resource strategy. However, the efficiencies of these strategies and many metal stabilization mechanisms need to be fully understood to ensure product safety in long-term applications. Moreover, the generalization of ceramic technology for heavy metal stabilization is always limited due to a relatively high temperature of ceramic sintering. Therefore, this study intends to develop low-temperature reacting ceramic matrices to incorporate Pb, Cr, and Cd, and find out the stabilization mechanisms for three metals. An intensive study will be conducted on the explication of crystalline structures for Pb, Cr, and Cd incorporation, and the quantitative X-ray diffraction techniques will be adopted to quantify the stabilization efficiencies and partition ratios of Pb, Cr, and Cd in the ceramic products. Furthermore, a prolonged leaching procedure will be carried out to examine the stabilization effect of Pb, Cr, and Cd in the ceramic matrices. Through the goal of pursuing lower temperature ceramic systems to react with the target metals, a novel and cost-effective stabilization methodology will be provided for heavy metals, and a “waste-to-resource” strategy will be developed to realize a safe utilization for metal-laden industrial wastes.
