Ability of swimming air blower, the import being connected with submerged water air blower water inlet are flexible coupling, and go out with what submerged water air blower delivery port was connected
Mouthful be flexible coupling, be arranged on import be flexible coupling on filter, the intake silencer being located on import is flexible coupling, be arranged on outlet
The structure that exit silencer on being flexible coupling collectively forms.
The film area is membrane bioreactor.
The anoxic zone, aerobic zone, film area, self priming pump, reflux pump, heavy Water fan be all disposed within a Upper rectangular, under
In the circular casing in portion.
The heavy underwater aerobic zone of Water fan, radiates by current, temperature when protection motor will not be due to normal work
Overheat and power off.
To detest/anoxic bacterium sewage decomposition region, the activated sludge progress denitrification for being back to the area takes off for the anoxic zone
Nitrogen, while polyP bacteria Ye Gai areas release phosphorus.
The aerobic zone is aerobic bacteria sewage decomposition region, and nitrobacteria aoxidizes ammonia nitrogen in the area, while polyP bacteria exists
Largely inhale phosphorus in the area.
Aerobic zone activated sludge is imported into anoxic zone by sludge reflux pump, anoxic zone sludge concentration is improved, improves simultaneously
The denitrification of anoxic zone.
The heavy Water fan of utilization and sludge reflux that are made using the technical scheme of patent of the present invention realize the MBR of denitrogenation dephosphorizing
Integration apparatus, the equipment are aerated to aerobic zone and film area using heavy Water fan, will not produce blower fan and blow oily situation；Simultaneously
Reflux pump is added in film area front end, by activity sludge reflux to anoxic zone to effectively improve the Nitrogen/Phosphorus Removal of activated sludge.

Embodiment
The present invention is specifically described below in conjunction with the accompanying drawings, as shown in Figure 1-2, one kind is returned using heavy Water fan and sludge
Stream realizes the MBR integration apparatus of denitrogenation dephosphorizing, including the regulating reservoir 1 being connected with sewage network, the regulating reservoir pass through lifting
Pump 2 is connected with the water inlet of anoxic zone 3, and the opening of the delivery port dividing plate bottom of the anoxic zone is described good from inflow aerobic zone 4
Oxygen area current enter film area 5 by advection, and film area delivery port connects the water inlet of self priming pump 16, the self priming pump by pipeline
Delivery port is connected to final delivery pipe 6 by pipeline, and the sludge reflux pump 7 of film area front end is connected with anoxic zone, described good
Oxygen area and film area connect the air outlet aeration of heavy Water fan respectively, and the heavy Water fan is by ground 8, is arranged on subtracting on ground
Pad 9, the submerged water air blower 12 on beam are shaken, the import being connected with submerged water air blower water inlet is flexible coupling 15,
The outlet being connected with submerged water air blower delivery port is flexible coupling 14, be arranged on import be flexible coupling on filter 13, be located at and
Mouth be flexible coupling on intake silencer 11, be arranged on outlet be flexible coupling on the structure that collectively forms of exit silencer 10.Wherein,
The film area is membrane bioreactor；The anoxic zone 3, aerobic zone 4, film area, self priming pump, reflux pump, heavy Water fan are all set
In the circular casing in a Upper rectangular, bottom；The heavy underwater aerobic zone of Water fan, radiates by current, protects motor
Temperature overheating when will not be due to normal work and power off；The anoxic zone is back to detest/anoxic bacterium sewage decomposition region
The activated sludge in the area carries out denitrification denitrogenation, while polyP bacteria Ye Gai areas release phosphorus；The aerobic zone is that aerobic bacteria is dirty
Water decomposition region, nitrobacteria aoxidizes ammonia nitrogen in the area, while polyP bacteria largely inhales phosphorus in the area；Aerobic zone activated sludge is led to
Cross sludge reflux pump and import anoxic zone, improve anoxic zone sludge concentration, while improve the denitrification of anoxic zone.
In the technical program, MBR integrated sewage treating apparatus is replaced at traditional biological using efficient membrane separation technique
Second pond in reason, due to the efficient crown_interception of film, microorganism is completely trapped in bioreactor, completely eliminates biography
Unite the sludge bulking problem of activated sludge process, the effect of damming of the machinery of film avoids the loss of microorganism, in bioreactor
High sludge concentration can be kept, so as to improve volume load, reduces sludge loading, and MBR techniques omit second pond, significantly
Reduce floor space, contaminant removal efficiency is high, processing effluent quality is good, can direct reuse, sludge yield is low, be easily achieved from
The many merits such as dynamic control cause MBR integrated sewage treating apparatus to turn into current more popular equipment.
During domestic sewage denitrifying：Under conditions of anoxic or anaerobism, denitrifying bacteria is by nitrite and nitrate
Nitrogen is reduced into, therefore film area leading portion increases sludge reflux pump, by sludge reflux to anoxic zone, can realize denitrogenation work with more efficient
With.PolyP bacteria discharges the phosphorus of sludge original tape under conditions of anoxic, and phosphorus is largely inhaled in aerobic zone, and this reduces phosphorus in water
Content, so as to play a part of dephosphorization.
