Background
In the field of sewage treatment and water resource recycling, a Membrane bioreactor (Membrane Bio-Re α, MBR) is a novel water treatment technology combining an activated sludge process and a Membrane separation technology.
The traditional aeration system (such as perforated pipe aeration and micropore aeration) is arranged at the bottom of the membrane tank and comprises an aerator, a blower, a valve, a controller and the like. The air blower continuously supplies air, the system supplies a large amount of air to the aerator through the pipeline in a short time, and a strand of air bubbles is transferred to the MBR membrane group through the aerator to help inhibit pollution of the membrane surface.
However, the above two aeration methods have disadvantages. Aiming at the aeration of the perforated pipes, aiming at the long line and the multiple holes of the perforated pipelines, in order to generate enough and large enough bubbles, the aeration of the perforated pipes needs a large amount of air and is arranged as densely as possible, so that enough and large enough bubbles can be generated to scrub the surface of the membrane, the bubbles are too large and concentrated, the local membrane surface can be unevenly scrubbed, the membrane can be unevenly scrubbed for a long time, the local part is not scrubbed and damaged, sludge is deposited and blocked to cause the reduction of the membrane filtering capacity and cause the overhigh energy consumption, the unit price of water treatment is increased, the increase of the perforated pipes causes the increase of valves, the manufacturing cost is further increased, and the maintenance cost is higher due to the continuous damage of the excessive valves in the daily production; aiming at the microporous aerator, the bubbles generated by the microporous aeration are uniform, and compared with the perforated pipe aeration, the microporous aeration is uniform, and the energy-saving benefit is better. But the oxygen charging capacity of the microporous aeration to the MBR membrane tank is more than 3 times of that of the perforated pipe, and the manufacturing cost, installation and debugging cost of the micropores are high. The reflux ratio is increased, the total nitrogen of effluent is increased, the quality of effluent is unstable, and the unit price of water treatment is not superior to that of perforated pipe aeration.
Another obvious disadvantage is: the two aeration modes are that bubble flow drives sewage to wash upwards. The washing effect on the membrane surface is not ideal, and the membrane group needs to be periodically cleaned off line. The off-line cleaning is very labor intensive.
