Intermittent oxygen-supplying apparatus used for water treatment

Abstract

The invention discloses intermittent oxygen-supplying apparatus used for water treatment. The apparatus comprises an oxygen pump, a treatment tank, a gas conveying pipe and an oxygen supplying device;the oxygen pump is fixed on the top of the treatment tank, the output end of the oxygen pump is connected with the oxygen supplying device through the gas conveying pipe, and the oxygen supplying device includes a supporting frame, fixing rods, a shell body, a gas inlet pipe, a flow quantity controlling device, a backflow preventing device, a connection block, a gas outlet pipe, a base seat, a dispersing device and an oxygen supplying pipe; and two ends of the supporting frame are fixed to the inner wall of the treatment tank, the top of the shell body is fixed to the supporting frame throughthe fixing rods, the output end of the oxygen pump is connected with the gas inlet pipe through the gas conveying pipe, the gas inlet pipe is fixed to the top of the shell body, and the gas inlet pipe communicates with the flow quantity controlling device. The intermittent oxygen-supplying apparatus used for the water treatment disclosed by the invention can intermittently supply oxygen to sewagelocated in the treatment tank, reduce waste of the oxygen, make the oxygen distributed more uniform in the sewage, and accelerate efficiency of the water treatment.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an intermittent oxygen supply device for water treatment. Background technique [0002] Water treatment methods include physical treatment and chemical treatment. Human beings have used water treatment methods for many years. Physical methods include the use of various filter materials with different pore sizes, and the use of adsorption or barrier methods to exclude impurities in water. Adsorption The more important method is to use activated carbon for adsorption, and the barrier method is to pass water through the filter material, so that the larger impurities cannot pass through, and then obtain relatively clean water. In addition, the physical method also includes the precipitation method, which is to let the impurities with a small specific gravity float on the water surface to remove them, or the impurities with a large specific gravity to settle down, and then obt...

Problems solved by technology

[0003] In the process of water treatment, some need to add oxygen to the sewage inside the treatment tank to speed up the efficiency of water treatment. The structure of the water treatment support device in the prior art is relatively simple, and it cannot provide oxygen intermittently according to the reaction of the sewage in the treatment tank. , so that the waste of oxygen is large, and it is not easy to control the rate of oxygen entering the sewage, and the distribution of oxygen is uneven, so that the reaction of sewage is not sufficient, reducing the efficiency of water treatment
