| 摘要 |
<p>The invention relates to a sewage treatment plant for waste water purification with at least one section for pretreatment, biological treatment and retreatment, with each section (6, 7, 8) being divided in several chambers (6a-f, 7a-f, 8a-f) separated from each other by dividing walls (4, 5). The chambers are connectable such that the route taken by the water flowing through the plant may be varied depending on the type of waste water to be treated. Sludge may be removed from sections 6 and 8 by screw conveyors (10), stored in a container for stabilising the sludge, and returned, if necessary, to section (7). <IMAGE></p> |
