摘　　要：城市污泥堆肥过程中易产生和排放恶臭气体,造成二次污染。系统总结了污泥堆肥过程中主要恶臭物质:氨气(NH3)、硫化氢(H2S)和挥发性有机物(VOCs)的产生机理及其影响因素,并对常用除臭技术工艺进行了技术和经济比较分析。通过对污泥堆肥厂恶臭气体的产生和释放特征的分析,针对除臭工艺自身技术特点,建议采用组合式除臭技术解决污泥堆肥厂的恶臭污染问题。Producing and releasing of the malodorous gases is common in the process of sludge composting, which can cause secondary pollution. The production mechanism and affecting factors on the main odor substances such as ammonia （ NH3 ） , hydrogen sulfide （H2S） and volatile organic compounds （VOCs） in the process of sludge composting were summarized. Comparison of the traditional deodorizing methods were made on economy and technique. Based on the production and characteristics of the odor in sludge composting plants, it is suggested to solve the problems of odor pollution by combined deodorizing techniques.
