- 摘要：固定床生物膜反应器和序批式反应器分别是废水处理中附着生长型和悬浮生长型反应器的典型代表.对比研究表明,两种生物反应器的总氮容积去除潜力相当(大约1960mg·L-1·d-1),都明显优于传统硝化反硝化工艺;在供试条件下,序批式反应器所需的启动时间(30d)可比生物膜反应器(40d)缩短13;序批式反应器中的菌体积累量大于生物膜反应器;但序批式反应器抗基质浓度冲击和水力负荷冲击的能力弱于生物膜反应器.
- Abstract：Fixed-bed biofilm reactor and sequence batch reactor are two kinds of common bioreactors in wastewater treatment. The comparison of their performance showed that volumetric removal potential of total nitrogen in the sequence batch reactor was close to the biofilm reactor (1960mg·L-1·d-1). Both of them were far higher than the traditional nitrification and denitrification process. In the experiment, the start-up time for the sequence batch reactor was one third shorter than the biofilm reactor. And the biomass accumulation in the sequence batch reactor was higher than that in the biofilm reactor. However, the sequence batch reactor could tolerate smaller pulse of substrate concentration and hydraulic load than the biofilm reactor.
