摘要
生物技术以其能在常温常压下将污染物降解为无毒无害的简单物质、无二次污染、运行费用低等优点,目前已应用于许多废气处理,并已经形成了一套关于可生化气体的净化原理和工业应用经验的重要体系。文中介绍了生物技术处理污水处理厂、养殖场排放的恶臭气体、工厂排放的硫化物的发展,并分析了解决生物膜堵塞的途径,以及分子生物学在废气生物处理中的应用研究,提出生物净化废气技术的发展方向,期待该技术在国内能得到更广泛的应用。
Biological treatment provides an cost effective and environmentally friendly alternative for many waste gas emissions. Biological waste air treatment is achieved at ambient temperatures, it does not generate secondary pollutants, such as nitrogen oxides, it has become in many instances the method of choice for the control of low concentrations of odors, volatile organic compounds, or hazardous air pollutants in large air streams. A significant body of knowledge and experience has been generated on biological waste gas purification. Examples of waste gas treatment are presented in this paper, such as at municipal wastewater treatment plants, emission from live stock industries, sulfur emissions from industries. This paper discusses the problem of how to prevent biomass clogging and introduces the application of molecular biotechnology in biologeical treatment. The development trend of the Biological treatment are discussed. We hope the biological treatments can gain widely application in China.
