| 摘 要： | 通过长期运行试验,考察了改进型膜生物反应器(MBR)对污染物的去除效果和减缓膜污染的能力.结果表明,改进型NBR对COD和NH3-N的去除效果与传统MBR的类似,出水COD和NH3-N分别低于50 mg/L和5 mg/L;改进型MBR对TN的去除效果优于传统MBR,且具有更好的减缓膜污染的能力,在近90d的连续运行过程中,改进型MBR的膜组件仅需清洗2次.而传统MBR的膜组件则清洗了5次.

| Abstract: | Through a long-term experiment, the performance of modified membrane bioreactor (MBR) for contaminants removal and membrane fouling alleviation was investigated. The results show that the removal effect of COD and NH3-N by the modified MBR is similar to that by the traditional MBR. The effluent COD and NH3-N in both processes are less than 50 mg/L and 5 mg/L. However, the removal effect of TN by the modified MBR is superior to that by the traditional MBR, and it has better performance for alleviating membra... |
