| 摘 要： | 活性污泥法运行过程中经常受泡沫问题的影响,导致处理效果的降低以及运行费用的提高.大量研究表明,污泥中某些丝状菌或放线菌的过度增殖是造成活性污泥工艺中泡沫问题的主要原因.讨论了活性污泥过程中泡沫的产生原因、已知的发泡微生物的种类、影响发泡的环境因素和过程参数及常用的泡沫控制技术,并对污泥消化过程中的泡沫问题作了简单的介绍.

| Abstract: | Severe foaming in activated sludge plant increase operating cost and/or reduce treatment performance. The foam is caused by the excessive growth of some filamentous bacteria and actinomycetes in activated sludge mixed liquor. This paper presents the mechanisms of foam formation, the responsible microorganisms, environmental factors and important process parameters affecting the form formation of foam as well as some effective foam control strategies. The foaming issue in anaerobic sludge digester is also presented. |
