In figure, 1-MBR pond；2-MBR diaphragm；3-self priming pump；4-elevated tank；5-backwash electromagnetic valve；6-filtered water tank；7-produces water solenoid valve；8-liquid-level switch；9-aeration tube；10-blower fan；11-air inlet pipe.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
The present embodiment one is without pump MBR diaphragm back purge system, the MBR diaphragm 2 including MBR pond 1, being located in MBR pond, self priming pump 3, elevated tank 4 and backwash electromagnetic valve 5 as shown in Figure 1.MBR diaphragm 2, self priming pump 3, elevated tank 4 are sequentially connected in series, and backwash electromagnetism 5 and self priming pump 3 are in parallel.The outlet of MBR diaphragm 2 connects the water inlet of self priming pump 3, and the outlet of self priming pump 3 connects the water inlet of elevated tank 4.The outlet of elevated tank 4 connects the water inlet of backwash electromagnetic valve 5, and the outlet of backwash electromagnetic valve 5 connects the outlet of MBR diaphragm 2.When the MBR diaphragm 2 in MBR pond 1 produces water (during sucks sewage work), backwash electromagnetic valve 5 cuts out, and self priming pump 3 is opened, and the MBR diaphragm 2 in MBR pond 1 produces in water is extracted into elevated tank 4 by self priming pump 3 and stores；When MBR diaphragm 2 quits work and carries out backwash, backwash electromagnetic valve 5 is opened, and the clean water in elevated tank 4 enters the MBR diaphragm 2 in MBR pond by the pipeline of backwash electromagnetic valve 5, carries out backwash.
The present embodiment also includes filtered water tank 6 and produces water solenoid valve 7, and filtered water tank 6 is in parallel with the branch road producing water solenoid valve 7 composition and elevated tank 4.Filtered water tank 6 is connected the outlet of self priming pump 3 by producing water solenoid valve 7.Elevated tank 4 is provided with liquid-level switch 8, the height of water level in sensing elevated tank 4；Liquid-level switch 8 and product water solenoid valve 7 link.When MBR diaphragm 2 works, MBR diaphragm produces water and is pressed onto in elevated tank 4 by self priming pump 3, when the liquid level in elevated tank 4 reaches liquid level, and liquid-level switch 8 action, produce water solenoid valve 7 and open, MBR produces water and flows to filtered water tank 6.
The present embodiment also includes being located at the aeration tube 9 bottom MBR pond 1, the blower fan 10 being located at outside MBR pond 1 and air inlet pipe 11, and blower fan 10 connects aeration tube 9 by air inlet pipe 11.
