摘要 随着我国经济快速发展,工业固体废物产量不断增多,特别是化工、制药、印染等行业产生的大量有害工业废盐对人体健
康和自然环境安全造成了严重的威胁,同时也制约着企业的快速发展。在总结近年我国工业废盐处理处置方法的基础上,介绍
了工业废盐的产量、特征和危害,以及工业废盐处理的常规方法,重点分析了当前工业废盐热处理技术,其中包括传统热处理技
术和新型热处理技术。在传统热处理技术中,主要介绍了回转窑焚烧技术、流化床焚烧技术和液体喷射焚烧技术等。在新型热
处理技术中,介绍了悬浮炉处理技术、分级碳化技术、熔融盐氧化技术、高温热管技术和微波吸收技术。对比分析了不同热处
理技术处理效果和优缺点,系统梳理了我国工业废盐热处理技术的最新发展进程。此外,探讨了工业废盐热处理技术过程中有
机污染物的消除机制,包括活性氧的产生机理以及有机污染物消除随温度的变化情况。最后,总结了在热处理过程中废盐所含
的非金属元素(主要 为 N 和 S 等)、重金属元素迁移转化规律,以及二噁英可能造成的二次污染问题。

Abstract The rapid development of economy in China has resulted in the mass production of industrial solid
wastes. Especially in the chemical, pharmaceutical, printing and dyeing industries, the large amount of hazardous
industrial waste salts has caused a serious threat to human health and the safety of the natural environment and
restricted the rapid development of enterprises as well. On the basis of summarizing the treatment and disposal
methods of industrial waste salts in China in recent years, the output, characteristics and hazards of industrial waste
salts were introduced, and the common methods for the treatment of industrial waste salt were reviewed. Current
thermal treatment technologies used in disposal of industrial waste salts in China were analyzed, including both
traditional and new-type thermal treatment technologies. The traditional thermal treatment technologies such as
incineration in a rotary kiln, incineration in a fluidized bed, and liquid jet incineration and new-type thermal
treatment technologies such as incineration in a suspended furnace, graded carbonization, molten salt oxidation,
high-temperature thermal pipe technology and microwave absorption technology were investigated. The treatment
effects, advantages and disadvantages of different thermal treatment technologies were compared and analyzed, and
the latest development progress of industrial waste salt thermal treatment technologies in China was systematically
combed. In addition, the elimination mechanisms of organic pollutants in the process of these technologies were
