Abstract
PURPOSE: To certainly impart a predetermined head to a downward flow passage by connecting a casing forming a downward flow passage and a closed pipe passage and providing a pipe with a small diameter to an upper portion of the casing in a protruded manner to discharge a gas in an upper portion of the casing.
CONSTITUTION: A downward flow passage A and an upward flow passage B are formed by a casing 1, 2 and, to an upper portion of a casing 1 forming the downward flow passage A, a cover 4 is auxiliarily provided to connect the closed pipe passage C for pumping up water comprising a pipe 5 and a pump P; and a pipe 6 with a relatively small diameter is protruded to a top portion of the pipe 5 in such a manner that the free end side thereof is opened to the atmospheric air to be communicated and connected. The treated water contg. the activated sludge is circulated and flowed over the upward and downward flow passage A, B and the closed pipe passage C. In this time, bubbles of dissolved gas and a slight amount of a gas raising from the downward flow passage A are successively accumulated to the closed pipe passage C, but said accumulated gas is withdrawn from the small diameter pipe 6. Thereby, water treatment corresponding to pollution load is carried out while a head tank is eliminated.
