MULTI-STAGE WASTEWATER PLANT WITH WASTEWATER Ponds FOR CLEANING VARIOUS WASTEWATER TYPES AND / OR FOR TREATMENT SLUDGE.

摘要

The invention relates to a multi-stage clarification plant for treating various types of waste water and for treating sewage sludge in which any desired number of waste water ponds, but at least two waste water ponds, trickle surfaces covered over with vegetation and mineral grain frameworks as soil filters are connected by centrally driven flow circuits (Fig. 4). The central flow drive (13) having a propeller pump (29) can be operated by wind energy. The waste water ponds are constructed as an inner pond (4) or (4a)/(4b) etc. and outer pond (2), which are separated by a bank (3) or (3a)/(3b) etc. with filter surfaces (21) and filter bodies (22) below. Shore areas (5) and (6) are laid out around the outside of the outer pond (2), which areas act as trickle surfaces and soil filters covered over with vegetation. A rampart filter (11) surrounds the plant as an emergency overflow having purifying action. IMAGE
