【摘要】 综述了国内外有机废气生物处理的3种典型工艺———生物洗涤器、生物滤池和生物滴滤塔的研究现状,针对存在的问题,提出新的研究方向,包括针对高浓度废气和较难生物降解的物质,培养专属菌种并优化其生存条件;提高疏水性或难降解废气的处理能力;改善生物滤料、填料的物理性能和使用寿命;实现自动控制等.指出生物处理法比传统工艺投资少,运行费用低,操作简单,应用范围广,是有机化工和石油化工行业有机废气处理的理想技术.更多还原

【Abstract】 The present status of three typical volatile organic compounds (VOC) bio-treatment processes: bio-scrubber, bio-filter and bio-trickling filter, are discussed with unresolved problems and possible solutions pointed out, which include application of genus of bacterium to treat high concentration VOC and its hard biodegradable substrates; improvement of the treatment capacity of hydrophobic or hard biodegradable VOC; updating of the physical property of carriers to extend their longevities and auto-control system. It was pointed out that bio-treatment of volatile organic compounds has the following advantages: cost-effectiveness, easy operation and adaptive to a wide area.更多还原
