摘要
垃圾填埋气中存在的多种微量挥发性有机物(VOCs),既造成二次污染,影响了人类健康;又对填埋气的回收利用产生了不利影响。本文综述了几种VOCs常规净化技术的基本原理、优势及限制,介绍了几种新兴技术,并预期有效的联合工艺是净化填埋气中微量VOCs的研究方向。
There are many kinds of trace volatile organic compounds (VOCs) existing in landfill gas (LFG), which not only bring (secondary) pollution and do harm to human health, but exert opposite influences to LFG recovery and utilization as well. In this paper, (principle), advantages and disadvantages of several different conventional technologies for removing VOCs from LFG are firstly (summarized), then some emerging techniques are introduced. It is expected that in the future effective joint-technique is the research trend for purifying VOCs from LFG.
