Abstract

PURPOSE: To make the construction of a deep layer aeration tank simple and reduce power consumption by providing an air blow port to the upper part of a descending pipe, and connecting the lower part of the descending pipe to one end of an aeraion chamber which is alternately formed with plural pieces of ascending parts and descending parts.
CONSTITUTION: The treating liquid supplied through a treating liquid inlet 12 to the lower part in an ascending pipe 1 ascends in the pipe 1, and during the time while it desends together with the air blown through an air blow pipe 11 in a descending pipe 2, air is dessolved in the liquid. Thence, the liquid enters an aerate chamber 3 from the lower part of the pipe 2, and after it repeats the ascending in ascending parts 4 and the descending in desending parts 5, it enters a deaeration part 6, where it is deaerated. Further, while it is maintained of the level constant, it is withdrawn by a circulating pump 8 and is circulated to the pipe 1 through a circulating line 10. When the above-described circulation is repeated, the aeration treatment is accomplished, and the treated liquid is withdrawn through a treated liquid outlet 13.
