Embodiment
See Fig. 1, the utility model provides a kind of MBR Sewage treatment systems, and this MBR Sewage treatment systems comprises membrane cisterna 1, suction unit 2 and water outlet pipeline 3; Membrane cisterna 1 comprises MBR membrane module 11; The water-in of suction unit 2 communicates with MBR membrane module 11, and its water outlet communicates with water outlet pipeline 3; Suction unit 2 is submersible pumps, and this submersible pump is arranged on below membrane cisterna 1 liquid level.In this MBR Sewage treatment systems, the structure of suction unit 2 is overall adopts diving design, effectively can improve the water production rate of MBR Sewage treatment systems and protect electromechanical equipment from damage.
See Fig. 2, above-mentioned submersible pump comprises the housing 23 that submersible machine 21, impeller 22 and cover are connected to submersible machine 21 and impeller 22 outside; Submersible machine 21 and impeller 22 are connected; The water-in 24 of above-mentioned suction unit 2 and water outlet 25 are laid respectively at the two ends of submersible pump and are connected by the inside of housing 23; The housing 23 that the water purification processed through MBR membrane module 11 enters submersible pump from water-in 24 is inner, is discharged by water outlet 25.Submersible pump also comprises and is arranged on submersible pump water outlet 25 place in order to control the non-return valve 26 of flow direction.Non-return valve 26 can prevent liquid from flowing backwards in the course of the work.
See Fig. 1, this MBR Sewage treatment systems also comprises the fluid level controller 4 be arranged on submersible pump, and fluid level controller 4 is placed in water-in 24 place of submersible pump.In the course of the work; along with the flux of MBR membrane module 11 progressively declines; the suction deficiency of suction unit 2 causes the water production rate of MBR Sewage treatment systems to decline; fluid level controller 4 has low liquid level defencive function, by detecting the liquid level in membrane cisterna, can directly work by control and suck device 2; such as when fluid level controller 4 detects that liquid level in membrane cisterna is lower than a certain value; signal is passed to suction unit, and suction unit quits work, and reaches the object preventing suction unit from dallying.
Use-pattern of the present utility model and working process as follows:
See Fig. 1, submersible pump entirety diving is arranged on below membrane cisterna 1 liquid level, and also only the water-in 24 of submersible pump can be placed in below membrane cisterna 1 liquid level, wherein the water-in 24 of submersible pump communicates with MBR membrane module 11, water outlet 25 communicates with water outlet pipeline 3, and water outlet pipeline 3 is provided with valve 5.Before startup, housing 23 inside of submersible pump is full of liquid, and submersible machine 21 and impeller 22 are all entirely flooded by liquid; After being switched on power by supply lead 27 on submersible pump, submersible pump is started working.That is: submersible machine 21 starts, impeller 22 high speed rotating, the liquid of submersible pump housing 23 inside rotates together along with impeller 22, under centrifugal action, fly away from impeller 22 outwards penetrate, liquid speed in housing 23 of injection is slack-off gradually, pressure increases gradually, then discharges from the water outlet 25 of submersible pump.Now, the blade center place of impeller 22 due to liquid be thrown toward around and formed both do not had air there is no the vacuum low-pressure district of liquid, under the atmospheric effect in face, pond, the housing 23 that the water purification processed through MBR membrane module 11 in membrane cisterna 1 flows into submersible pump from the water-in 24 of submersible pump is inner, so, the water purification processed through MBR membrane module 11 is constantly aspirated by submersible pump and is discharged by water outlet 25.Wherein, the non-return valve 26 at water outlet 25 place can prevent liquid from flowing backwards; The fluid level controller 4 being arranged on submersible pump water-in 24 place has low liquid level defencive function; can directly control submersible pump work; along with the flux of MBR membrane module 11 progressively declines; can prevent submersible pump from dallying; not only simplify whole MBR Controlling System, also make whole MBR Sewage treatment systems more safe and reliable.
