Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) consist of 210 kinds of pollutants, 17 of which are highly toxic to humans. PCDD/F is mainly produced during combustion and incineration processes. This review focuses on the formation, measurement, and control of dioxins in municipal solid waste incineration. Typical PCDD/F emission concentrations and air pollutant control devices are introduced in the work. The formation mechanisms of PCDD/F are divided into homogeneous synthesis and heterogeneous synthesis, and some previous reviews and the latest work are introduced. Considering the complexity, high cost, and time lag of traditional offline detection methods based on high-resolution gas chromatography coupled with high-resolution mass spectrometry, fast and indirect measurement techniques have been recently developed, among which resonance-enhanced multiphoton ionization-time-of-flight mass spectrometry is a good option. The study of online/at-line in situ measurements and the correlation between PCDD/F and the indicator are reviewed in detail. Due to the strict policies regarding pollutants’ emissions, state-of-the-art remediation technologies are used to reduce dioxin formation and emission from incineration. A comprehensive discussion about the control of dioxin emission is also reviewed in this work. Finally, challenges, future directions, and perspectives are proposed.

焚化城市固体废物中二恶英的形成，测量和控制：最新进展和展望

多氯化二苯并p-二恶英（PCDDs）和多氯二苯并呋喃（PCDFs）由210种污染物组成，其中17种对人类具有高毒性。PCDD / F主要在燃烧和焚烧过程中生产。这篇综述着重于城市固体垃圾焚烧中二恶英的形成，测量和控制。工作中介绍了典型的PCDD / F排放浓度和空气污染物控制装置。PCDD / F的形成机理分为均相合成和异质合成，并介绍了一些以前的综述和最新工作。考虑到传统的基于高分辨率气相色谱结合高分辨率质谱的离线检测方法的复杂性，高成本和时滞，最近开发了快速和间接测量技术，其中共振增强的多光子电离飞行时间质谱是一个不错的选择。详细回顾了在线/在线原位测量的研究以及PCDD / F与指标之间的相关性。由于对污染物排放的严格政策，采用了最先进的修复技术来减少二恶英的形成和焚烧产生的排放。在这项工作中还对有关二恶英排放控制的全面讨论进行了回顾。最后，提出了挑战，未来方向和观点。最先进的修复技术用于减少焚烧过程中二恶英的形成和排放。在这项工作中还对有关二恶英排放控制的全面讨论进行了回顾。最后，提出了挑战，未来方向和观点。最新的修复技术用于减少焚烧过程中二恶英的形成和排放。在这项工作中还对有关二恶英排放控制的全面讨论进行了回顾。最后，提出了挑战，未来方向和观点。
