污水除臭技术的应用及研究现状

The application and research status of deodorization techniques for wastewater

近年来城市污水处理设施数量不断增加,由此产生的臭气污染严重影响了环境空气质量,并严重损害了城市居民健康。污水脱臭问题引起广泛关注。通过介绍除臭技术在污水处理厂的实际应用,分析了常用除臭技术的优缺点和适用条件,阐述了目前低温等离子体法及纳米材料净化法等除臭新技术的研究现状,同时对除臭技术发展趋势进行展望,为实际工程应用提供指导。

The number of urban wastewater treatment facilities is increasing constantly in recent years. The re-sulting odor pollution has affected the ambient air quality and damaged the health of urban residents seriously. The sewage deodorization has aroused widespread concern in now days. This paper introduced the practical application of deodorization technologies used in wastewater treatment plants,and analyzed the advantages,disadvantages as well as the applicable conditions of common deodorization technologies. The research status of some new technologies, inclu-ding low temperature plasma and the nano-materials purification technology, were expounded. This paper also prospec-ted the development tendency of deodorization technologies, which could provide guidance for engineering applications.
