| 摘 要： | 近年来大量使用含有机硅氧烷材料造成硅氧烷作为污染物进入环境,数量逐年增加.在垃圾填埋场和污水处理厂消化产生的生物气(沼气)中出现的硅氧烷会在燃烧过程中结垢,十分不利于生物气的利用,必须清除.本文综述了硅氧烷的理化性质、在环境中的迁移转化规律与生物降解性能、在生物气中的浓度分布以及去除技术,并对生物气应用中的硅氧烷的控制对策研究作出展望.作者强调,需进一步深入研究硅氧烷的生物降解的机理.

| Abstract: | Siloxane has become an environmental concern as poly-dimethylsiloxanes are extensively applied. Siloxanes in biogas generated from landfill and anaerobic digestion at wastewater treatment plants must be removed before the biogas is used for electricity generation in case of production of silicon precipitates inside an engine. This paper reviews the updated research results on siloxanes including physical-chemical properties, contaminant sources, migration and transformation in environment, biodegradability, concentration profile in biogas, and current technologies for siloxane removal. The topics of future study are discussed, focusing on mechanism of biodegradation and microbiology. |
