摘　　要：本文对当前城市污水厂恶臭气体处理技术及其应用现状进行了综述,具体介绍应用于城市污水处理厂的生物除臭技术,离子除臭技术,化学吸收处理技术以及全催化除臭治理技术。分析表明,化学吸收技术对恶臭气体的处理简单易行,可操作性极强,但处理效率低;生物除臭技术对恶臭气体处理净化效果好,但设备运行对环境温度要求较为苛刻,该处理技术在北方低温环境应用受到局限;离子除臭技术对恶臭气体转化率高,但设备运行能耗高,且可能产生二次污染物;而全催化恶臭气体处理技术对恶臭气体中的硫化氢,有机硫组分去除率极高,运行费用低,无二次污染物生成,是一种经济高效且极具应用前景的除臭技术。In this paper,the treatment technology and application of odor gas in urban sewage treatment plant are reviewed.The biological deodorization technology,ion deodorization technology,chemical absorption technology and total catalytic deodorization technology applied in urban sewage treatment plant are introduced.The analysis shows that the chemical absorption technology is simple and easy to deal with the odor gas,with strong operability,but low treatment efficiency;the biological deodorization technology has good purification effect on the odor gas treatment,but the operation of the equipment requires strict environmental temperature,so the application of the treatment technology is limited in the low temperature environment such as northern;the ion deodorization technology has high conversion rate of the odor gas,but the operation energy consumption of the equipment is high,and it may produce secondary pollutants in the process of treatment.However,the total catalytic technology for the odor gas treatment has high removal rate of hydrogen sulfide and organic sulfur components in the odor gas,low operation cost,and no secondary pollutants.It is an economic,efficient and promising deodorization technology.
