Example Embodiment

[0007] Specific implementation mode 1: Combination figure 1 To explain this embodiment, a composite membrane bioreactor for the treatment of micro-polluted water source water in this embodiment includes a reaction vessel 1, a mixture of attapulgite and activated sludge 2, a water distribution tank 3, an air pump 4. Membrane module 5, inlet pump 6, outlet pump 7 and clean water tank 8, attapulgite and activated sludge mixture 2 are filled in the reaction vessel 1, the inlet pump 6 is connected to the distribution tank 3 through a pipeline, and the inlet pump 6 also passes The pipeline is connected to the reaction vessel 1, the output end of the air pump 4 is communicated with the pipeline between the water inlet pump 6 and the reaction vessel 1, the membrane module 5 is installed in the reaction vessel 1, and the membrane module 5 is immersed in the attapulgite and active In the sludge mixture 2, the output end of the membrane module 5 is connected to the input end of the water ...

Example Embodiment

[0009] Specific implementation manner two: combination figure 1 To explain this embodiment, the composite membrane bioreactor for the treatment of micro-polluted water source water in this embodiment also includes a backwash pump 9, a solenoid valve 10, and a time relay 11. The solenoid valve 10 is installed in the outlet pump 7 and On the pipeline between the membrane modules 5, the input end of the backwash pump 9 is connected to the clean water tank 8 through the pipeline, the output end of the backwash pump 9 is connected to the solenoid valve 10 through the pipeline, and the two control ends of the time relay 11 are respectively Connect with the outlet pump 7 and the backwash pump 9.

[0010] In this embodiment, the time relay 11 controls the water discharge and backwashing time, and the backwash is performed for 3 minutes every 28 minutes of water discharge.

[0011] The technical effect of this embodiment is: through the control of the time relay and the solenoid valve, the...

Example Embodiment

[0013] Specific implementation mode three: combination figure 1 To explain this embodiment, the composite membrane bioreactor for micro-polluted source water treatment described in this embodiment further includes a water level controller 12 installed in the attapulgite and activated sludge mixture 2 , The water level controller 12 is used to control the open and closed state of the water inlet pump 6.

[0014] In this embodiment, when the water level in the reaction vessel 1 reaches the lowest water level, the water level controller 12 turns on the water inlet pump 6 and water starts to enter the reaction vessel 1. When the water level reaches the highest water level, the water level controller 12 turns off the water inlet pump 6.

[0015] The technical effect of this embodiment is that the membrane bioreactor is operated and controlled according to the set minimum water level and maximum water level through the water level controller, and the water inlet pump is automatically clo...

The combined membrane biological reaction device provided by the invention is used for treating sewage.

Description

technical field [0001] The invention relates to a composite membrane bioreaction device, in particular to a composite membrane bioreaction device for micro-polluted water source water treatment. Background technique [0002] At present, in the field of sewage and wastewater treatment, membrane bioreactors have been rapidly developed worldwide and have become one of the most popular and efficient sewage treatment technologies. However, due to the relatively low organic load of slightly polluted source water and the Membrane fouling and other problems in the bioreactor itself have limited the application of the membrane bioreactor in the field of micro-polluted water treatment. The existing membrane bioreactors have poor decontamination effect on slightly polluted water, serious membrane pollution, and short service life of the membrane components. Contents of the invention [0003] In order to solve the problems that existing membrane bioreactors have poor decontamination ...
