Analysis of Anti-Shock Loading Capacity of Bio-Ferric MBR

By changing influent COD volume loading and dyestuff volume loading of membrane bio-reactor, the anti-shock capacity of traditional MBR and bio-ferric MBR was analyzed comparatively. The experiment results showed: whatever the influent COD volume loading altered, the supernatant and effluent COD in bio-ferric MBR varied less than that in traditional MBR, and the discreteness was smaller which indicated that the reinforcement of bio-ferric sludge could enhance the system stability, and the anti-shock loading of bio-ferric MBR was much better than traditional MBR. While the influence of the influent dyestuff volume loading on dyestuff concentration in supernatant and dyestuff removal efficiency was smaller. The relationship between influent COD volume loading and dyestuff loading and removal volume loading were linear.
