<p>A method of bio-aeration of waste water using the two-degree anaerobic-aerobic method of purification, in particular of waste water with medium to heavy contamination by organic substances in which raw waste water treated by acidification is mixed with recirculated condensed sediment of the anaerobic degree (3) together with the recirculated condensed sediment of the aerobic degree (5), with the following separation of the biogas in process of formation from the activated sediment and from the pre-purified water which latter in the aerobic degree (5) is mixed with the recirculated condensed activated sediment, with the following separation of purified water from the activated sediment whose one part recirculates into the aerobic degree (5) and whose the other part is mixed with raw waste water treated by acidification before the entry into the anaerobic degree (3). The device consists of a container (1) in whose lower part there is provided an inlet (a supply) of raw waste water equipped with a blender (8). In the upper part of the anaerobic degree (3) there is provided a three-phase separator (4), and in the upper part II. of the aerobic degree (5) there is also provided a separator (6). <IMAGE></p> |
