摘要
活性污泥法运行过程中经常受泡沫问题的影响,导致污水处理效果的降低。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、发泡的影响因素及几种有效的泡沫控制技术。结合具体实例,分析了泡沫产生的原因,提出了解决泡沫问题应采取的预防和改进措施。
Severe foaming in activated sludge plant reduce treatment performance,The foam is caused by the excessive growth of somefilamentous bacteria and actinomycetes in activated sludge mixed liquor. This paper presents the mechanisms of foam formation,the responsible microorganisms,impact factors of foam and some effective foam control strategies.This paper analyzes the reasons of foam creation combing a concretely example, Put forward to solve the foam problem definitely should adopt of prevention and improvement measure.
