【摘要】 对MBR一体化中试设备中的MBR膜组件曝气系统和运行条件进行改进以及优化,并将其与常规MBR曝气系统及运行方式进行中试对比。试验结果表明:MBR中试设备采用新型MBR曝气系统及运行方式运行时,与常规MBR曝气系统及运行方式相比,其气水比可降低约20%,反洗周期至少可以延长1.2倍以上,但是对提高膜通量作用较小。采用新型MBR曝气系统及运行方式较常规MBR曝气系统的运行能耗可减少约14%左右。更多还原

【Abstract】 MBR aeration system and operation mode was improved and optimized in pilot-scale MBR integration equipment,and a contrast experiment was carried out with conventional MBR aeration system and operation mode. The results showed that compared with the conventional MBR aeration system and operation mode,the air / water ratio in the new MBR aeration system could reduce about 20%,backwashing cycle could extend more than 1. 2 times at least and the energy consumption of MBR could reduce about 14%,but it had smaller effect on increasing the membrane flux.更多还原
