附增缓冲区的膜-生物反应器临界通量改进测定法
An Improved Step-wise Method to Determine Critical Flux of Membrane Bioreactor by Adding Relaxation Zone
摘要
Abstract
The critical flux of submerged flat membrane bioreactor (MBR) was measured by an improved flux-stepwise method and the measured values under different relaxation time were analyzed. The result was that with longer relaxation time, asymmetry of Flux-TMP and Flux-Permeability decreases remarkably with much lower membrane residual resistance and better fouling reversibility in sub-critical flux zone and without obvious hysteresis. The relaxation-zone-attached flux-stepwise method can better describe the principle of flux-permeability and alleviate the impact of reversible fouling.关键词
