  • The dynamic membrane forming on the surface of 0.105 mm industrial filter cloth and steel mesh was utilized to replace the static membrane, so as to develop a submerged dynamic membrane bioreactor (DMBR) for corn starch processing wastewater treatment. The results showed that after forming of dynamic membrane on the two substrate membranes, most of the suspended solids could be held back completely. Furthermore, dynamic membrane was generated faster (in 30-60 min) on filter cloth and achieved better filtering efficiency. With the constant-flow operation mode of starting with high flux and running with low flux, the effluent turbidity was below 1.5 NTU on average, and SS not checked out. When HRT was 22 h, MLSS was 5 g/L, the removal efficiency of CODCr and NH4+-N reached 93.1% and 94.8% respectively, and the effluent average concentrations were 34.5 and 5.2 mg/L, respectively.
