城市生活垃圾堆肥厂臭气的产生及防控技术进展

阐述了城市生活垃圾堆肥厂臭气的产生、成分及其危害,认为垃圾堆肥厂臭气成分概括来讲主要分为硫化物、胺类、挥发性脂肪酸、酮类以及醛类,但详细、完整的臭气成分还有待于今后进一步研究。对于臭气的防止及其控制技术,进行了总结。堆肥臭气主要防止措施包括在堆肥结构、通气方式、外加改良物质等方面进行的优化与控制。着重介绍了四种生物除臭法,即生物过滤法、生物洗涤法、生物滴滤法和曝气式生物除臭法的各自特点和技术进展。最后认为由于垃圾堆肥恶臭成分的多样性,单一的处理方法往往效果有限,两种或两种以上的方法联用具有较好的发展前景。

Progress on Prevention and Control Measures of Odor Emission

The production mechanism and main components of odor originated from municipal solid waste (MSW) composting facilities are described. The main odor components are sulfide, amine, volatile fatty acid, ketones and aldehydes while comprehensive profile data need further study. The most popular control method for odor from the composting is biological treatment including biofiltration, bioscrubber, biotrickling filter and activated sludge aeration. As the odor components are complicated and fluctuating, the removal efficiency by single method is limit, and combination of several methods is more effective and provided with better development.
