The resource utilization of municipal solid waste incineration fly ash (MSWI FA) has been widely concerned at present. The chlorine removal from MSWI FA is of great significance for controlling environmental risk and improving materials properties in the process of its resource utilization. This work specifically proposes to divide the chlorine in MSWI FA into inorganic chloride and organic chloride. The removal rate, influencing factors, and removal mechanism of chlorine in MSWI FA using various technologies were systematically analyzed. In addition, the applicability, advantages and disadvantages of chlorine removal technology in different scenarios were highlighted. This work identifies the technical barriers that need to be solved urgently in the current research and proposes a key direction for future research on the regulation of chlorine removal technologies of MSWI FA.
目前，城市生活垃圾焚烧飞灰（MSWI FA）的资源利用受到广泛关注。在MSWI FA的资源利用过程中，脱氯对于控制环境风险和改善材料性能具有重要意义。本工作具体提出将MSWI FA中的氯分为无机氯和有机氯。系统分析了采用各种技术对MSWI FA中氯的去除率、影响因素及去除机理。此外，还突出了不同场景下氯去除技术的适用性、优缺点。本工作明确了当前研究中亟待解决的技术障碍，并提出了未来MSWI FA氯去除技术调控研究中的关键方向。
