摘要

The invention relates to a method for testing planted and unplanted soil systems for their suitability for wastewater treatment and a test unit. The object of the invention to develop a generic method and a test unit with which the described disadvantages of the prior art are avoided and with which a realistic and complete balance, including the gas phases, can be achieved by a method which thereby is characterized in that a defined, concentric flow is generated in a test unit from a water to be treated by the water to be examined is sucked out of an inner circuit and fed to an outer circuit. The test unit according to the invention is characterized in that a reactor (1) consists of an outer ring (2) and an inner ring (3) arranged concentrically therewith, between which there is a fixed bed material such as soil, sand, gravel and which is gas-tight Upper end (4) is provided with plant openings (5) and a bottom (11), openings (12, 13) for inlet and outlet lines (6, 7) being provided.
