<p>PROBLEM TO BE SOLVED: To provide an active sludge treatment device using a dynamic filtration membrane capable of stably conducting a filtration by stably forming a dynamic layer on the membrane. SOLUTION: At one side of a bioreactor 1, an air diffuser 3 is arranged and at the other side thereof, a plurality of dynamic filtration membranes 6 are also arranged along the vertical direction in parallel so that there is a proper space between the membranes wherein a plurality of equalizing plates 8 are arranged along the vertical direction in parallel with the line of the contiguous dynamic filtration membranes 6, and a treating water pipe 14 is installed in such a manner that the pipe is penetrated into each dynamic filtration membrane 6.</p> |
