Research progress of volatile organic compounds treatment technologies

随着工业生产的发展,挥发性有机物的排放量及污染物成分持续增加,针对治理成分复杂、对人体危害极大的挥发性有机物,相继涌现出多种处理工艺。介绍了典型的挥发性有机物的特点,对比了物理、化学、生物3类处理工艺,对其中的吸附法、等离子体法、生物滴滤法等处理技术进行了综述。通过分析当前挥发性有机物的成分及处理技术,提出了未来挥发性有机物处理方法的改进方向和趋势。

With the development of industrial production,the emission of volatile organic compounds and pollutant components continue to increase.A variety of technologies and processes for treatment of VOCs have emerged.This paper briefs the typical characteristics of VOCs,summarizes and compares corresponding physical,chemical and biological treatment technologies,and summarizes in detail the treatment technologies such as adsorption,plasma and biological methods.The traditional treatment technology has low cost,mature technology and large processing capacity,but it can not meet the current situation of industrial production,especially decomposition of a variety of mixed polluting gases.Emerging technologies and combined technologies have the advantages of high purification efficiency,no secondary pollution and low energy consumption,which will be a continuous research hotspot in the future.By analyzing the current emission characteristics of VOCs and the corresponding treatment technologies,this paper discusses the most significant advantages and disadvantages of each technology as well as the difficulties that need to be overcome in the future.Finally,the future improvement direction and trend of VOCs treatment methods are put forward.
