摘要
综述了挥发性有机物治理技术的研究进展,介绍了吸收法、吸附法、冷凝法、膜分离法、生物法、等离子体法、光催化法、直接燃烧法、蓄热式燃烧法、多孔介质燃烧法及催化燃烧法等。其中,蓄热式催化燃烧法具有较好的发展前景。不同的挥发性有机物特征有很大差别,而各种治理方法适用范围有限,单一处理工艺已无法满足治理要求,因此多种工艺联合使用将在大气污染治理方面具有广阔的前景。分析了多种常用治理技术的原理、适用条件及优缺点,并对发展方向进行了展望。
Volatile organic compounds(VOCs) have attracted wide attention because of their great harm to environment and human health. The related information of absorption method,condensation method,membrane separation method,biological method,plasma method,photocatalytic method,direct combustion method,regenerative combustion method,porous media combustion method and catalytic combustion method was introduced in this paper. Among these techniques,regenerative catalytic oxidation is one of the most promising methods. The applicable scope of various governance methods is limited due to the various discharge characteristics in different factories. Therefore,a combined technique is a promising method and has a recognized result without second pollution,which is an important direction of VOCs removal. The principles,application conditions,advantages and disadvantages of various commonly used governance technologies were compared and their development directions were prospected,which provided a theoretical basis for the selection of treatment methods for factories.
