METHOD FOR MIXING AND / OR AERATION OF LIQUIDS, ESPECIALLY WASTE WATER, ESPECIALLY USING A WATERED AERATOR

摘要

1. A method of mixing and / or aeration of liquids, especially wastewater, comprising the following cyclically repeated steps a) and b):! a) aerate the liquid for a predetermined first time interval (t1) using an immersion aerator containing at least one aeration device (1) located on a carrier (3, 43) made in the form of a flooded hollow body (2, 42) moreover, the hollow body (2, 42) is flooded, and air is supplied through the aeration device to the liquid to ensure nitrification in the liquid,! b) mix the liquid for a predetermined second time interval (t2) using an immersion aerator, whereby the air supply through the aeration device (1) is throttled or stopped, while the previously flooded hollow body (2, 42) is emptied by supplying air under pressure for filling it with gas or air, as a result of which the submersible aerator assumes the function of a mixing device, rises upward in the liquid and mixes the liquid, allowing denitrification in the liquid . ! 2. The method according to claim 1, characterized in that the first and second time intervals (t1, t2) are controlled by a control device. ! 3. A submersible aerator for implementing the method according to claim 1 or 2, containing at least one aeration device (1) located on the supporting device (3, 43), and the submersible aerator contains at least one flooded hollow body (2, 42 ) formed by the supporting device (3, 43). ! 4. Submersible aerator according to claim 3, characterized in that the flooded hollow body (2, 42) is made in the form of an elongated pipe. ! 5. П�
