Biological purification of waste water by - the activated sludge process
摘要
<p>Purification plant comprises an activating tank with a large bypass used as storage tank for long-period activation. In the chamber enclosed by the bypass is a secondary settler combined with another tank which is used as collecting vessel for aerobically stabilised sludge. It is then used for aerobic sludge stabilisation and finally as intensive activating tank with a special settling section which is placed in front of the activating tank of the bywash.</p>
