<p>A plant for waste water biological purification contains a cylinder- shaped tank where on the bottom without air-gap a vertical cylinder large-diameter baffle is mounted and fixed on the small-diameter stake. The baffle of smaller diameter together with the bottom form an aeration zone where the aeration device and container with upper and lower circle gagger-guide paths are placed. On the gaggers the elements of wire-line rope grab are placed. The aeration device contains sequentially mounted an air pipe-line, a collector, perforated circular elements. The baffle of larger diameter together with a tank wall form a sludge zone and together with the small-diameter baffle it form suspended active sludge layer. A clearing zone is formed by cylindrical baffle of he smaller diameter and the wall of a tank. In the upper part of clearing zone is mounted a circular tray. Over aeration zone there is a mesh filter, a container with a bag made of filter fabric fixed with grids and also the container with filtering bag where upper airlift socket ends.</p> |
