Energy-conserving accurate aeration equipment of little oxygen based on MBR

The utility model relates to an in the energy-conserving accurate aeration equipment of little oxygen of MBR, all be provided with micropore aeration pipe and DO on-line measuring appearance in said good oxygen pond and the membrane biological reaction pond, first oxygen deficiency pond still is provided with agitating unit and DO on-line measuring appearance in the second oxygen deficiency pond, and micropore aperture on the micropore aeration pipe be 1.0mm, and micropore aeration manages the automatically regulated valve of installing the 0-100% aperture on, and the automatically regulated valve is rather than corresponding DO on-line measuring appearance structure passing signal line connection component micropore aeration 0 according to AA2O-MBR technology, combine the device provided by the utility model, at low dissolved oxygen, under the high load capacity sludge concentration for acclimated microorganism quantity maximization in the biological treatment pond, the fungus crowd becomes privileged, and the degradation high efficiency realizes the geodetic anti- nitration that nitrifies, reaches effectual dissolved oxygen and sludge concentration's control, satisfies nitrogen and phosphorus removal's requirement, reaches town sewage factory again and proposes target emission requirement
