Abstract
En 中文
Multi-component solid waste combustion can recover energy and reduce the difficulty of waste classification, but variable solid composition complicates the reduction of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), which has been paid attention to by the international community. Therefore, this paper comprehensively elaborates on the application characteristics of multi-component solid waste, analyzes the current situation of its source-controlling of generation and emission, and summarizes the source inhibition of PCDD/Fs emission and the research methods of PCDD/Fs in terms of three aspects: PCDD/Fs degradation technology, quantum chemical analysis method, and new regulation technology. The PCDD/Fs degradation technology includes photocatalytic degradation technology, metal catalytic degradation technology, and catalytic degradation technology under high temperature conditions. Quantum chemical analysis methods include physical adsorption and desorption phase catalytic synthesis and degradation and heterogeneous catalytic synthesis and degradation. New control technologies include solid waste control technology, chemical looping combustion (CLC) technology, and flow field simulation control technology. The technology of PCDD/Fs degradation is an important aspect in further optimizing the conditions of source inhibition of PCDD/Fs. Calculating the energy barrier of formation and degradation from the perspective of quantum chemistry is an effective method for analyzing the migration and transformation of dioxin precursors. Furthermore, exploring the new regulation technology is also the new research direction for inhibiting and controlling the source of PCDD/Fs.
