PURPOSE: A circulating agitator containing membrane bioreactor without a pipe is provided to effectively implement treatment and to adjust the area ratio of the inlet parts of an anaerobic bath and an anoxic bath. CONSTITUTION: A circulating agitator containing membrane bioreactor without a pipe includes an anaerobic bath(3), an anoxic bath(4), an aerobic bath(5), a membrane filter(6), a deaerobic bath(2), a circulating agitator(7), an anaerobic bath inlet(8), and an anoxic bath inlet(9). The anaerobic bath allows microorganisms in transferring bath to emit phosphorus. The anoxic bath keeps the anoxic state of sewage and eliminates nitrogen from the sewage based on a denitrification action. The aerobic bath keeps the aerobic state of the sewage. The sewage is nitrified in the aerobic bath, and organic materials in the aerobic bath are decomposed. The membrane filter filters overlaying water from the sewage. The deaerobic bath mixes transferred sewage and introduced sewage to reduce dissolved oxygen in the sewage. The circulating agitator agitates sludge and transfers the sewage from the membrane filter to the deaerobic bath. |
