Abstract
A method and a device for purifying waste water is described, in particular for an anaerobic purification, in a container receiving a medium under the development of gas, wherein the gas developing is caught by a gas collector, ingredients of the medium entrained by the gas are separated and the ingredients separated are passed back into the medium below the gas collector. In order to improve the purification effect in a constructively simple manner, it is suggested to take in medium from the upper portion of the container by a gas lifting effect of the rising gas and to conduct it back into the container.

A method of purifying waste water, in particular an anaerobic purification, in a container receiving a medium under the development of gas, wherein the gas developing is caught by a gas collector, ingredients of the medium entrained by the gas are separated and the ingredients separated are passed back into the medium below the gas collector, characterized in that caused by a gas lifting effect of the rising gas, medium is taken in via an intake line from the upper portion of the container above the gas collector and is conducted back into the container.
A device for purifying waste water, in particular by an anaerobic purification, comprising a container (19) receiving the medium, a waste water intake (2), an outtake (22) for purified water, at least one gas collector (3) arranged in the container (19) and a line (18, 4) leading upwardly from the upper portion of the gas collector, characterized in that above the gas collector (3) in the upper portion of the container (19) an orifice of an intake line (9a) is arranged, wherein the line (18) of the gas collector (3) opens into the intake line (9a) in a manner that the gas coming from the gas collector (3) can be used as a gas lifter for taking in the medium into the intake line (9a).
