Micro-slot plastic disc serial aerator

Abstract

The invention discloses a micro-slot plastic disc serial aerator which is characterized by comprising a perforated pipe connecting rod (1), wherein dozens of micro-slot plastic discs (2) which are connected in series into a regular cylinder, an elliptic cylinder or a rectangular cylinder are installed on the connecting rod (1). Air is aerated from the micro-slots and forms medium and microbubbles in water. Outer threads (3) are formed at two ends of the perforated pipe connecting rod (1) and used for fixing the micro-slot plastic discs and further for connecting an inlet air pipe and installing pipe plugs. The faces of the plastic discs at two end of the micro-slot plastic disc serial aerator are made from airtight plates (4) and other micro-slot plastic discs are hollow ventilating cascades (2). The aerator disclosed by the invention is simple and easy to design and use, high in oxygen utilization rate, small in resistance, power-saving, large in service area, high in bubble uniformity, long in service life, stable and reliable in operation and simple to regenerate, can save energy during sewage treatment and is convenient to manage.

Description

technical field [0001] The invention relates to an aeration tank aeration equipment, which is installed on an aeration pipeline in the aeration tank, plays an important role in cultivating microorganisms and purifying sewage, and belongs to the technical field of environmental protection equipment. technical background [0002] Aeration and oxygenation equipment is a key device in sewage biological treatment technology, and it is widely used in activated sludge process and biofilm process. However, the corundum aerator, rubber aerator and other aeration and oxygenation equipment currently in use have rapidly increased loss of running resistance, easy to block, easy to age, low oxygen utilization rate, uneven bubbles, power consumption, and poor adaptability. And the maintenance is difficult, which affects the operation effect.
