| 摘 要： | 提出了一种新型的间歇循环活性污泥-膜生物反应器（ICAS-MBR）工艺,并应用其对传统的活性污泥工艺进行改造以强化氮、磷的去除并使出水能够回用.该工艺通过控制活性污泥混合液在曝气室、搅拌室之间进行间歇式循环,使微生物种群在时空上依次经历缺氧、厌氧、好氧阶段,从而达到强化脱氮除磷的目的.考察了ICAS-MBR工艺对生活污水中污染物的去除特性,在6个月的运行期间,对COD、TN、TP、NH4＋-N的平均去除率分别为93%、70.6%、86%、96%,出水浊度＜1 NTU,细菌总数＜100 CFU/mL,且具有良好的抗冲击负荷能力. |

| Abstract: | An innovative process, Intermittently Cyclic Activated Sludge-Membrane Bioreactor (ICAS-MBR) was proposed and used to modify the conventional activated sludge processes for the enhancement of nitrogen and phosphorus bioremoval and reuse of wastewater. The process mechanism is that the activated sludge is intermittently cycled between the aeration tank and mixed tank, thus the microorganism communities undergo anoxic/anaerobic/aerobic phases in space or time sequence. Consequently, the bioremoval of N and P can be enhanced. The removal performances of pollutants from domestic wastewater in the ICAS-MBR process were evaluated for 6 months. The results show that the average removal efficiencies of COD, TN, TP and NH+_4-N are 93%, 70.6%, 86%, 96%, respectively. The turbidity of the effluent is less than 1 NTU, and the number of bacteria in the effluent is less than 100 CFU/mL. Furthermore, the process has excellent ability in resisting shock load. |
