污泥干化废气特性及其治理技术研究进展
Study on the Characteristic and Treatment Technology of Sludge Drying Waste Gas
【摘要】 污泥干化是目前市政污泥主要处理方式,污泥干化过程会产生大量恶臭废气,严重污染大气环境,必须严格治理。文章总结分析了污泥干化废气的主要污染成分:粉尘、VOCs以及恶臭气体,如氨气、硫化氢、胺类有机物和有机硫化物气体等。并进一步分析了包括吸收法、吸附法、生物法、等离子体法和光催化法等,处理污泥干化废气的常用方法。在掌握污泥干化废气特征和处理方法优缺点的基础上,提出了未来污泥干化废气治理技术的发展方向。
【Abstract】 At present, sludge drying is one of the main sludge treatment methods. There are a lot of waste odor gas produced in the drying process. Therefore, it is necessary to treat it very carefully. The major pollutants of the sludge drying waste gas are analyzed in this paper, including dust, volatile organic compounds(VOCs) and odor gas, such as NH3, H2S and other volatile nitrogen substances and sulfur substances. And the common treatment technologies for the sludge drying waste gas are also analyzed,including the absorbing method, the absorption method, the biological method, the plasma method and the photocatalytic method.Based on the characteristic of the waste gas and the strength and weakness of the treatment methods, the development direction of the sludge drying waste gas treatment technology in the future is proposed.
