Plastic sheet overlaid and mounted porous aeration equipment

Abstract

The invention discloses plastic sheet overlaid and mounted porous aeration equipment which is characterized by comprising a connection rod (1), wherein the connection rod (1) is provided with multiple aeration sheets (2); the diameters of the aeration sheets (2) are successively increased, and the aeration sheets (2) are overlaid to form a cone shape; a fixed interface (3) is installed on the lower end of the connection rod (1); and a gas inlet interface (5) is installed on the lower end of the fixed interface (3). The plastic sheet overlaid and mounted porous aeration equipment has the characteristics that the structure is compact and reasonable; the service life is long, and cleaning and exchange are not needed; service area is large, resistance is small, and operation is stable and reliable; adaptability is strong, the equipment is suitable for purification treatment of various sewages; and oxygen utilization rate is high, bubbles are uniform, and no dead angle is generated, thereby solving the problems generated by using the traditional aeration oxygenation equipment and having better aeration effect.

Description

technical field [0001] The invention relates to an aeration and oxygen-increasing equipment for an aeration tank, which is used for installing on an aeration pipeline to purify sewage, and belongs to the technical field of environmental protection equipment. Background technique [0002] Aeration devices have been used as sewage treatment technology for a long time. At present, they are widely used in sewage treatment processes such as contact oxidation method and activated sludge method, such as corundum aerators and rubber aerators. However, the biggest disadvantages of these aeration and oxygenation equipment are large resistance loss, easy to block, easy to age, low oxygen utilization rate, poor adaptability, easy to produce dead angle, uneven bubbles, etc., and the maintenance is very inconvenient, which affects aeration The dissolved oxygen effect of the pool. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned d...
