Summary: | The invention relates to the technical field of sewage treatment and discloses an electric field enhanced MBR sewage treatment process. By setting retention time of an amplifying reaction tank, waterquality and water volume can be balanced sufficiently, sewage is enabled to enter subsequent treatment units in a comparatively uniform manner, impact resistance of a whole system is improved, arrangement scale of the treatment units is reduced, and reducing of running cost and impact caused by water quality fluctuation is facilitated; by utilizing nitrate brought in by mixed liquid of hydrolysisacidifying backflow and an organic matter carbon source in incoming water for denitrification to enable NO2-/NO3- in the incoming water to be reduced into N2 to realize denitrification effect, ammonianitrogen value is lowered while organic matter is removed; facultative anaerobes in water can oxidatively decompose macromolecular organic matter difficult for aerobes to degrade into easy-to-degrademicromolecular organic matt |
