城市垃圾填埋场温室气体及VOCs排放的研究进展

随着城市垃圾填埋量的增加,填埋气体造成的环境问题被愈加重视,国内外对填埋气的产生和排放也进行了大量研究,以温室气体和挥发性有机物为主要研究对象。综述了最近几年国内外学者针对填埋场垃圾和填埋气中3种重要温室气体和挥发性有机物(VOCs)的产生模型、产量估计及其监测方法优劣、减排和资源化利用等领域进行的研究成果,指出后续对填埋气间的相关性和由此产生的次生污染物进行适当研究的必要性,与填埋气产生排放相关的气象条件监测也应加强,旨在为填埋气体的相关研究提供参考。

ADVANCED PROGRESS OF GREENHOUSE GASES AND VOCs FROM MUNICIPAL SOLID WASTE LANDFILL

With the rapid increase of municipal solid waste landfill，air pollution caused by landfill gases draws more attention． A lot of research has been carried out on landfill gases emission，which concentrated on greenhouse gases and volatile organic compounds． This paper summarizes the recent research progress of three kinds of greenhouse gases and volatile organic compounds in municipal solid waste landfill． The emission estimate，generation models，advantages and disadvantages of monitoring methods，and volatile organic compounds treatment and reutilization，of the solid wastes and landfill gases，both in China and overseas，are introduced． The necessity of research on the correlation among the appropriate landfill gases and secondary pollutants， and meteorological conditions concerning landfill gas emissions monitoring should also been strengthened．
