| 摘 要： | 厌氧附着膜膨胀床(AAFEB)反应器是近几年开发的新型高效的厌氧消化工艺。在这种反应器内,厌氧微生物被固定在载体上,形成一定厚度和活性的具有生物膜结构的生物颗粒。这样,可以持留高浓度的厌氧活性污泥,使污泥滞留时间(SRT)与水力滞留时间相分离,不受其限制,为AAFEB高效稳定地运行创造了重要的条件。

| Abstract: | The characteristics of bioparticles in AAFEB reactor with continuous steady state operation has been studied In this paper. The biological mechanism for high efficiency operating performances of AAFEB reactor with steady state from these respects as follow:sludge retention time (SRT), microbial compositions (methanogens) in bio-film, change and distribution features of acid producing activity, methane producing activity and coenzymc F420 contents of bioparticle, which obtained from various sampling spots of AAFEB reactor during operation. Meanwhile, it is also showed that substrate transfer resistance exists in bioparticles or biofilm, and becomes of significance at low substrate concentration and in thick biofilm. |
