摘要
城镇污水处理厂运行中产生恶臭气体并因此导致空气污染的问题日益严重。生物除臭技术具有操作简便、运行成本低、二次污染小等优点,适用于污水处理厂恶臭气体的处理。阐述了污水处理厂臭气的主要成分、浓度及分布特点,分析了生物除臭技术的4个关键影响因素(微生物、营养液、pH和填料),并结合影响因素剖析了3个工程应用典型案例,总结了生物除臭技术亟需解决的问题,并展望进一步研究的内容,以期为不同污水处理厂根据其自身条件解决的恶臭污染提供参考。
The operation of urban wastewater treatment plants(WWTPs) has caused more and more serious odor pollution. Biological deodorization technology has the advantages of easy operation, low operating cost and no secondary pollution, and is applicable to the treatment of malodorous gases in WWTPs. In this study, the main components, concentration and distribution characteristics of odor in WWTPs were described. Four key influencing factors(microorganism, nutrient solution, pH and packing) of biological deodorization technology were annalyzed. Three typical engineering application cases were annalyzed based on the influencing factors. The urgent problems and future development of biological deodorization technology were summarized, in order to provide reference for different sewage treatment plants to solve odor pollution.
