As the same section is concerned, near the bottom the maximum value of frequency appear within 1mm of bubble size, towards the water face this value tend to decrease, yet the corresponding size turns to increase; in the same time, the frequency is concentrated near the bottom and deconcentrated near the water face; under the experiment condition, the maximum frequency of the total section approximately appear at 0.5mm size; mean bubble size access 0 at bottom and increase acceleratively towards water face where tend to be infinite; total number increase during developing of aeration, and become steady when reach wholly developed area; on the same section, the total number in unit time tend to increase at first and decrease then, along the water depth.

N-(2-hydroxyethyl)-glucamine was dehydrogenated to 6-(2-droxyethyl) amino-6-deoxy-a-L-sorbofiuanose the key intermediate of miglitol by the resting cells of Gluconobater oxydans Gouv2007 through aeration. 6-(2-Droxyethyl) amino-6-deoxy-a-L-sorbofiuanose was hydrogenated catalyticlly to miglitol. In the transformation of N-(2-hydroxyethyl)-glucamine to miglitol, the transformation rate was 77.3%.

As to these problems, a novel MBR named internal circulation membrane bioreactor is developed, in which the aeration not only supplies the required oxygen, but is utilized for the circulation of nitrified wastewater. It carries out the nitrogen and carbon removal of domestic wastewater in a single treatment unit. Simulated domestic wastewater is used in this research.
