APPARATUS FOR INCREASING DISSOLVED OXYGEN IN AERATION TANK

摘要

PURPOSE: An apparatus for increasing dissolved oxygen in an aeration tank is provided to process water which is available to inhabitation of microorganism, and to circulate the whole processed water in the aeration tank. CONSTITUTION: An apparatus for increasing dissolved oxygen in an aeration tank includes an aeration tank(1), an air pump(2), and an air injection nozzle(3). The air transferred by the air pump is sprayed to the processed water in the aeration tank. A processed water embedded body(11) is arranged on a surface layer of the processed water. The processed water embedded body includes a plurality of processed water overflowing bodies(12) and a plurality of processed water derivatives(13). The processed water embedded body is installed at a frame(11a), and is arranged on the surface layer of the processed water. A pipe(13a) is connected to the bottom of the processed water embedded body.
