To date, heavy metals and chlorine removal from hazardous waste incineration fly ash (HWI FA) by thermal treatment was scarcely reported. High content of calcium in HWI FA might affect heavy metals chlorination volatilization. The aim of this study was to realize heavy metals and chlorine simultaneous removal from HWI FA triggered by fluidized-bed municipal solid waste incineration fly ash (FBMSWI FA) during sintering. Results showed that the dilemma of low heavy metals removal efficiency was due to the dense structure and the difficulty of transformation of the stable phases including Cu₂S, CuSiO₃, and Zn₂SiO₄. By co-sintering with FBMSWI FA at the ratio of 1:1, the removal efficiency of Cu, Zn, Pb, Cd, and Cl reached as high as 84.4%, 92.0%, 99.9%, 99.5%, and 99.7%, respectively. Compared with the control, chlorination volatilization efficiency of Cu and Zn was significantly increased by 210.5% and 89.2%. The favourable promotion could be mainly attributed to Si/Al matrix in FBMSWI FA triggered the following reaction: i) Ca-bearing compounds in HWI FA were activated to destroy the dense structure, which facilitated the transformation of Cu₂S to CuO; and ii) the conversion of NaCl and KCl to gaseous chlorine was promoted, which the formation of metal chlorides was accelerated.

迄今为止，几乎没有报道通过热处理从危险废物焚烧飞灰 (HWI FA)中去除重金属和氯。HWI FA中钙含量高可能影响重金属氯化挥发。本研究的目的是实现在烧结过程中由流化床城市固体垃圾焚烧飞灰 (FBMSWI FA) 引发的 HWI FA 中重金属和氯的同时去除。_{结果表明，重金属去除效率低的困境是由于Cu 2}S、CuSiO₃和Zn₂SiO₄等稳定相结构致密且难以转变。. 与FBMSWI FA按1:1共烧结，Cu、Zn、Pb、Cd、Cl的去除率分别高达84.4%、92.0%、99.9%、99.5%、99.7% . 与对照相比，Cu和Zn的氯化挥发效率显着提高了210.5%和89.2%。有利的促进可能主要归因于 FBMSWI FA 中的 Si/Al 基体引发了以下反应： i) HWI FA 中的含钙化合物被激活以破坏致密结构，这促进了 Cu 2 S 向 CuO 的_转变；ii）促进了NaCl和KCl向气态氯的转化，从而加速了金属氯化物的形成。
