Kompakte naturnahe Abwasserteich-Bodenfilter-Kläranlage mit Untergrundversickerung zur Reinigung verschiedener Abwasserarten

摘要

The compact pond, with a natural look, has a base filter for cleaning different types of waste water for underground drainage uses a number of soils for the construction, bonded or unbonded on in alternating layers. The waste water is cleaned naturally through alternating between naturally aerated ponds (2,3,4) with overgrown base filters (5-9) and in a free fall without additional energy supplies. It is then allowed to seep as clean water into the ground water system.A number of ponds (2-4) are assembled together with natural aeration, with flows to mix the anoxic and oxygen content zones with each other to give simultaneous nitrification and denitrification so that, after a long flow time, the water reaches the inlet zone (12) again. Base filters (5-7) are at the surfaces between the ponds (2-4) to retain floating matter. A growing base filter system (9) with suspended trickling (8) is round the ponds (2-4) for further water cleaning.
