| 摘 要： | 在MBR反应器中分别采用活性污泥和颗粒污泥,通过比较两种不同形态的污泥在相同运行条件下膜通量的变化趋势及膜污染的变化情况,研究可提高MBR性能的措施。研究结果表明:在相同的实验条件下,颗粒化污泥MBR系统内的膜通量明显高于活性污泥系统的膜通量,同活性污泥MBR系统相比,颗粒化污泥MBR系统将显著降低操作过程的能耗。同时由于颗粒化污泥MBR系统显著地降低了膜污染的可能性,因而可使MBR系统在不用清洗的条件下长时间稳定地运行。

| Abstract: | MBR performance has been investigated with activated and granular sludges,respectively.Through comparing the flux variation as well as membrane fouling status in both MBR systems,the method of improving MBR performance has been studied.Experimental results indicate that the permeate flux of MBR with granular sludges is much higher than that of the system with conventional activated sludges under same operational conditions.MBR system by using granular sludges will greatly reduce the energy consumption as co... |
