中文摘要：

固定化微生物技术是一种新型的污染物治理技术。由于其具有微生物密度高、微生物流失量少、产物易分离以及耐毒性强等优点,固定化微生物技术广泛应用于环境污染治理。阐述了固定化微生物技术在治理NH3、H2S、SO2、VOCs等废气的研究进展,并提出了其存在的问题和未来的发展方向。

英文摘要：

Immobilized microorganism is a kind of novel biotechnology in pollutant treatment.Due to that it has many advantages,such as a higher concentration of biomass,less loss of microorganism,easier product separation and stronger anti-position,the immobilized microorganism technology is widely application in environmental pollution treatment.This paper summarized the studies on the application of immobilized microorganism technology in waste gas purification,such as NH3,H2S,SO2,VOCs and so on.Additionally,the existing problems and the developmental trends in immobilized microorganism technology are proposed.
