随着我国经济高速发展,餐饮油烟(COFs)排放量与日俱增,其释放的油烟颗粒物(CFPM)和气态挥发性有机物(VOCs)对人们身体健康和生态环境造成的危害持续增加,由此引发了科研工作者的高度关注。传统的油烟净化技术如高压静电法、离心分离法、过滤法和液体洗涤法等,已经不能满足排放要求;一些成熟的VOCs治理技术在这个背景下被应用到餐饮油烟的VOCs净化中,并取得了显著进展。鉴于此,本综述总结了高温催化氧化技术、低温等离子体-催化氧化技术的最新进展,着重分析了餐饮油烟VOCs消除应用中催化材料的特点及发展趋势,以期为餐饮油烟VOCs高效净化技术的研究提供参考和借鉴。 相似文献

Due to the increasingly strict emission standards of NOx on various industries, many traditional flue gas treatment methods have been gradually improved. Except for selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR) methods to remove NOx from flue gas, theoxidation method is paying more attention to NOx removal now because of the potential to simultaneously remove multiple pollutants from flue gas. This paper summarizes the efficiency, reaction conditions, effect factors, and reaction mechanism of NO oxidation from the aspects of liquid-phase oxidation, gas-phase oxidation, plasma technology, and catalytic oxidation. The effects of free radicals and active components of catalysts on NO oxidation and the combination of various oxidation methods are discussed in detail. The advantages and disadvantages of different oxidation methods are summarized, and the suggestions for future research on NO oxidation are put forward at the end. The review on the NO removal by oxidation methods can provide new ideas for future studies on the NO removal from flue gas. 相似文献

The adequacy and feasibility of methods recommended for allocation by the current international standard on life cycle inventory analysis (LCI) are reviewed. The review is based on the view that an LCI should provide information on the environmental consequences of manipulating technological systems. On this basis, subdivision and allocation based on physical, causal relationships are adequate methods to deal with allocation problems for certain multifunction processes where the production volume of exported functions are unaffected. Further research is needed to develop methods that can deal with a broader range of processes. System expansion is an adequate method when exported functions are affected if data can be obtained for the competing production of the exported function, and if the data uncertainties are not too large. In LCI practice, system expansion is often based on inaccurate data on the effects on the exported functions as well as on the indirect effects of changes in the exported functions. Further research is needed to establish what data should be used at system expansion. Other approaches to the allocation problems are adequate only where the effects on the LCI results are small. The ISO procedure should be revised to take into account the type of information provided by the different methods. 相似文献

浅谈土壤消解方法对重金属元素的选择 总被引:1,自引:0,他引:1
采用了4种消解方法来分析土壤中的铜、铅元素,得出结论:采用的消解方法不同,对土壤中的重金属元素的分离效果不同,重金属对土壤的消解方法具有一定的选择性。面临测试土壤中的铅元素时采用的消解方法最好有氢氟酸的参与,并且须带土壤标准,以得到准确的分析结果。 相似文献
