Novel water treatment aeration head

Abstract

The invention discloses a novel water treatment aeration head, which comprises a central air inlet pipe, wherein connection pipes are fixed at two ends of the central air inlet pipe; horizontal adjusters are arranged at the bottoms of the connection pipes; a mounting head is arranged in the middle of the central air inlet pipe; one end of the mounting head is connected with a ventilating pipe; thetop end of the ventilating pipe is connected with a sawtooth-shaped aeration head main body; one end of the sawtooth-shaped aeration head main body is provided with an aeration barrel; a through holeis formed in the inner wall of the aeration barrel; a flow guide plate is correspondingly arranged on the outer side of the through hole; the flow guide plate is fixed between a base and the bottom end of the aeration barrel; an aeration cavity is formed inside the base. According to the novel water treatment aeration head disclosed by the invention, by the arrangement of a sawtooth-shaped air dispersion plate and a foamed sponge layer, air passes through the foamed sponge layer and the sawtooth-shaped air dispersion plate to enlarge a contact area between air bubbles and sewage and enhance the aeration effect; the sawtooth-shaped air dispersion plate is clamped in an annular clamping slot and is fastened by a wabbler screw, so that the sawtooth-shaped air dispersion plate can be independently separated from the base and cleaned.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a novel water treatment aeration head. Background technique [0002] Aeration is a means of bringing air into intense contact with water, with the purpose of dissolving oxygen in the air into the water, or expelling unwanted gases and volatile substances from the water into the air. In other words, it is a means of facilitating the exchange of substances between gases and liquids. It also has several other important functions, such as mixing and stirring. The oxygen in the air is transferred to the water through aeration, and the oxygen is transferred from the gas phase to the liquid phase by mass transfer. This kind of mass transfer and diffusion theory is currently widely used in the double-membrane theory proposed by Lewis and Whitman. In the field of sewage treatment technology, aeration of sewage by using an aerator is an important link, which can fully ...

AI Technical Summary

Problems solved by technology

However, during the use of the prior art aeration head, the air bubbles generated are relatively large, so that the contact area between the air bubbles and the sewage is small, thereby prolonging the sewage treatment cycle. At the same time, the existing aeration head is also extremely prone to blockage require frequent maintenance
