Title:
TOWER-TYPE WASTE WATER TREATMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/147485
Kind Code:
A1
Abstract:
The present invention relates to a tower-type waste water treatment apparatus in which liquid and gas circulate along an ordered track, thereby improving liquid-gas mixture and oxygen transfer rate. The tower-type waste water treatment apparatus according to the present invention comprises: a chamber; a main nozzle; a draft tube; and a sub-nozzle. The chamber comprises: a reaction chamber in which the ratio of the height and diameter thereof is configured to be 5 to 7:1; and a deaeration chamber, which is provided on the upper side of the reaction chamber, for discharging gas discharged from the reaction chamber to the outside. The main nozzle comprises: a waste water tube which vertically penetrates through the reaction chamber from the upper side of the deaeration chamber and in which waste water is introduced; and an air tube, which is positioned in the center of the waste tube so as to be covered by the waste tube, for enabling air to be supplied together through the waste tube by means of a pressure change resulting from the supply of waste water. The draft tube has both ends open, and is installed on the lower side of the main nozzle so as to be positioned on the axial line with the main nozzle in the reaction chamber. The sub-nozzle comprises: an inlet which penetrates the reaction chamber from the side surface of the reaction chamber so as to be parallel with the lower surface of the reaction chamber; and an injection part which is vertically bent downwards from an end of the inlet and is positioned on the axial line of the main nozzle. When the diameter of the reaction chamber is 1200 mm and the height thereof is 8000 mm, the injection part is positioned at a height which is 2500 mm from the lower surface of the reaction chamber. According to the present invention, sediment is prevented from being piled up on the lower surface of the reaction chamber, and thus it is possible to remarkably increase volumetric loading and throughput.
