  • 摘要: 垃圾焚烧飞灰与垃圾渗滤液膜浓缩液协同处理能够解决2种废物处置难的问题，但二者协同处理产生的灰渣往往仍需进一步无害化处理。在分析灰渣的物理化学性质基础上，研究灰渣中重金属在热处理过程中的迁移转化特性，进而探讨灰渣热处理无害化的可行性。实验考察了不同热处理温度(300、600、800、1 000和1 200 ℃)对灰渣中重金属(Pb、Zn、Cu和Cd)的挥发率的影响，并分析热处理后灰渣的矿物相转化及重金属浸出毒性变化。结果表明：随着热处理温度的升高，重金属Pb、Cd的挥发率显著增大，Zn、Cu挥发率的增幅相对较小。热处理过程中，Pb、Zn、Cu、Cd在1 200 ℃时挥发率最大，分别为94.6%、68.9%、69.4%和97.7%。浸出实验结果表明，当热处理温度高于800 ℃时，热处理后灰渣中重金属Pb、Zn、Cu、Cr、Cd的浸出浓度均达到GB 16889-2008相关限值要求。研究结果显示，对飞灰协同处理后的灰渣进行热处理实现其无害化具有一定的可行性。
    Abstract: A difficult problem of disposing municipal solid waste incineration (MSWI) fly ash and membrane concentrated leachate could be solved by their synergistic treatment, but the produced ash residue from this synergistic treatment often needs further harmless treatment. Based on the analysis of ash residue physicochemical properties, the migration and transformation characteristics of heavy metals in ash residue were studied during the heat treatment, then the feasibility of ash residue harmless heat treatment was further investigated. The experiments were conducted to study the effects of heat treatment temperatures (300, 600, 800, 1 000 and 1 200 ℃) on the volatilization of heavy metals (Pb, Zn, Cu and Cd) in ash residue, and the mineral phase change and heavy metal leaching toxicity for the heat treated ash residue were also analyzed. The results showed that with the increase of temperature, heavy metals Pb and Cd presented a significant increase in the volatilization rate, while Zn and Cu present a relative smaller increase. During the heat treatment process at 1 200 ℃, the volatilization rates of Pb, Zn, Cu and Cd reached the highest values of 94.6%, 68.9%, 69.4% and 97.7%, respectively. In addition, the leaching toxicity test indicated that when the heat treatment temperature was higher than 800 ℃, the leaching concentration of Pb, Zn, Cu, Cr and Cd in heat treated ash residue could meet the relevant limit of GB 16889-2008. Thus, it is feasible that harmless treatment of ash residue, produced from the synergistic treatment of MSWI fly ash and membrane concentrated leachate, could be achieved through heat treatment.
