<p>PURPOSE:To effect efficient waste water treatment through controlling of anaerobic microbes by a method wherein waste water is clarified by aerobic microbes by use of a rotary filter member installed with plural net type cylinder bodies around the shaft. CONSTITUTION:Rotary frames 4 with supporting rods 3 are attached to the main shaft 1, and separated from the shaft 1, a net type immersion filter body 2 is fixed. Net type cylinders 7 are arranged in parallel in space 5 without gaps between the cylinders. The sectional area of the space 5 may be either fan-shape or angular- shape as shown by 6. The cross section of the cylinder 7 may be used in the shape of polygon, circle or annular. The structure of waste water treatment equipment enables to provide aerobic microbes with sufficient time and the amount of dissolved oxygen to treat waste water, so that efficient waste water treatment can be achieved.</p> |
