Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to an intelligent aerated oxygen-enriched water purification device. Background Art

[0002] Aeration is an important process link in aerobic biological treatment of sewage. It uses physical methods (such as blowing and spraying) to force oxygen in the air to dissolve into the water, increase the dissolved oxygen (DO) content in the water, ensure that the microorganisms, substrates, and DO in the reactor are fully mixed, promote the growth of aerobic microorganisms, and decompose organic matter in the water through microorganisms.

[0003] During the aeration process, the sludge concentration (MLSS) in the bioreactor is often high, resulting in the unsatisfied demand for oxygen by microorganisms, which in turn restricts the treatment efficiency of the bioreactor. There are currently two main methods to increase the dissolved oxygen (DO) content in water bodies. One is to increase the oxygen partial pressure in the gas phase and thus increase the solubility of oxygen in water, and the other is to increase the volumetric mass transfer coefficient of oxygen to the liquid phase. The corresponding technical solutions involve the use of a pure oxygen source or jet aeration, which can effectively increase the DO content in the water body. However, pure oxygen sources have the problem of harsh use conditions and high costs, and the radiation range of jet aeration is limited, resulting in uneven aeration in the bioreactor. The degradation capacity has been improved but the improvement is limited.

[0004] Therefore, it is necessary to provide an intelligent aeration and oxygen-enriched water purification device to solve the problems raised in the above background technology. Summary of the invention

DETAILED DESCRIPTION

[0030] It should be explained that there are two main ways to increase the DO content. One is to increase the oxygen partial pressure in the gas phase and increase the solubility of oxygen in water according to Henry's law. The specific common methods are to use pure oxygen for aeration or pressurized operation. The other is to increase the volumetric mass transfer coefficient of oxygen to the liquid phase according to the gas-liquid two-phase mass transfer mechanism. The common method is jet aeration, etc., which makes the air dispersed in the liquid phase and the bubble size is refined, thereby increasing the actual contact area between the two phases and increasing the DO value in the water phase.

[0031] This application is also based on the above two ways to increase DO content. The aeration equipment is improved to use oxygen-rich air as the main aeration air as the auxiliary aeration to improve the biological treatment efficiency, shorten the treatment time, and reduce the floor space. At the same time, the DO content is monitored and the aeration method is adjusted to achieve energy saving and efficient purification effects, avoiding excessive aeration that causes excessive saturation of the water body, releasing excess oxygen into the atmosphere, and affecting the surrounding ecology.

[0032] See also Figure 1-Figure 6 In an embodiment of the present application, an intelligent aeration and oxygen-enriched water purification device includes:

[0033] A base 1 is fixedly arranged at the bottom of the aeration tank, a support shaft 2 is arranged on the base 1, an adjustment head 3 is rotatably arranged at a fixed end of the support shaft 2, and a screw is arranged inside the support shaft 2, and the screw is adjusted by the adjustment head 3;

[0034] an aeration component 6, which is arranged on the support shaft 2, and the aeration component 6 is located in the aeration tank. The support shaft 2 is provided with a notch at a position corresponding to the aeration component 6, and the aeration component 6 is connected to the screw through the notch, that is, the aeration component 6 is slidably arranged on the support shaft 2, and the vertical position is adjusted by the adjustment head 3;

[0035] A suspension airbag 7 is fixedly arranged on the support shaft 2. A plurality of the suspension airbags 7 are evenly distributed around the support shaft 2, and the suspension airbags 7 are arranged close to the adjustment head 3. Specifically, the suspension airbags 7 assist in stabilizing the support shaft 2.

[0036] The oxygen-enriched generating assembly 5 and the blower 4 are arranged outside the aeration tank and are connected to the aeration assembly 6 via an air pipe. Specifically, the blower 4 is used to output air.

[0037] It should be explained that oxygen-enriched gas is generated by the oxygen-enriched generating component 5, air is provided by the blower 4, and the oxygen-enriched gas and air are simultaneously transported to the aeration component 6, wherein the aeration component 6 can be adjusted in height by adjusting the head 3 to radiate to sewage at different levels in the aeration tank, thereby increasing the aeration radiation range;

[0038] At the same time, the aeration component 6 transports treated sewage, air and oxygen-rich oxygen in different ways, and finally aerates the aeration tank in the form of a jet. At the same time, a DO monitor is set in the aeration tank to monitor the DO value of the water body, so that the aeration component 6 can adjust the aeration mode.

[0039] As a preferred embodiment, the aeration component 6 is vertically arranged, and the support shaft 2 is rotatably connected to the base 1. The support shaft 2 is rotated to adjust the direction of the aeration component 6, specifically to avoid dead corners in the aeration tank and affect the aeration effect.

[0040] In this embodiment, Figure 3 The oxygen-enriched generating component 5 includes an oxygen-enriched membrane group 51, a vacuum pump 53 and a vacuum gauge 56. The oxygen-enriched membrane group 51 is fixed by a fixing bracket 52, and the vacuum pump 53 is fixed by a support 54. The vacuum pump 53 is connected to the oxygen-enriched membrane group 51, and a vacuum gauge 56 is provided at the connection. Specifically, the separation layer of the oxygen-enriched membrane group 51 is in direct contact with the outdoor air. Under the action of the vacuum pump 53, a pressure difference is formed on both sides of the separation membrane, thereby producing oxygen-enriched gas. The vacuum pump 53 is also provided with an output head 55, and the output head 55 is connected to the aeration component 6 through an air pipe, and is specifically used to transport oxygen-enriched gas.

[0041] In this embodiment, Figure 4 The aeration assembly 6 includes a guide pump group 61 and a high-pressure cylinder group 62 which are connected in sequence from top to bottom. In the guide pump group 61, a pump body 612 is arranged on the support shaft 2 through a connecting bracket 611. Specifically, the pump body 612 is used to pump sewage in the aeration tank into the high-pressure cylinder group 62, and an air flow disperser 614 is fixedly arranged on the pump body 612, and an air intake joint 613 is opened.

[0042] As a preferred embodiment, the air intake connector 613 is connected to the blower 4 through an air pipe, and the air is transported into the high-pressure cylinder group 62 to assist in pressurization. The air flow disperser 614 is connected to the output head 55 through an air pipe, and the air flow disperser 614 is used to control the transmission direction and amount of the oxygen-rich gas. An auger 615 is rotatably arranged in the pump body 612, and the auger 615 extends into the high-pressure cylinder group 62. The auger 615 is used to stir the air, so that the bubbles are fully refined and the contact surface with the sewage is increased.

[0043] In this embodiment, Figure 5 , the high pressure cylinder group 62 comprises:

[0044] A continuous pressure chamber 621 is connected to the output end of the pump body 612, and air source connectors 622 are evenly distributed on the continuous pressure chamber 621, and the air source connectors 622 are connected to the air flow disperser 614 through an air pipe;

[0045] The bottom cover 623 is fixedly disposed at the bottom end of the continuous pressure chamber 621 , and a spoke plate 624 is provided on the bottom cover 623 . The spoke plate 624 extends to connect the main injection port 625 and the auxiliary injection port 626 provided on the bottom cover 623 .

[0046] As a preferred embodiment, the end of the auger 615 is rotatably disposed on the spoke plate 624 via a bracket, and a main injection head 627 is fixedly disposed on the main injection port 625 , and a secondary injection head 628 is fixedly disposed on the secondary injection port 626 .

[0047] It needs to be explained that gas coexists with water underwater, presenting a state of coexistence of gas phase and liquid phase. The two phases are in continuous contact and coexistence, and a mass transfer process occurs to increase the gas content in the liquid phase. During the working process, the auger 615 continues to stir, driving the sewage into the follow-up pressure chamber 621. During this period, the entrained air also enters the follow-up pressure chamber 621. Due to the mismatch between sewage input and output, high pressure is formed in the follow-up pressure chamber 621. Under the conditions of sufficient stirring and high pressure in the follow-up pressure chamber 621, the increase in DO content can be effectively promoted.

[0048] As a preferred embodiment, the main injection head 627 injects radially, the auxiliary injection head 628 injects axially, and the main injection head 627 is longer than the auxiliary injection head 628.

[0049] As a preferred embodiment, the gas source connector 622 and the auxiliary injection port 626 are connected via a conveying connection, specifically used for conveying oxygen-rich gas.

[0050] It should be explained that oxygen-rich gas is injected through the secondary injection port 626, and at the same time, sewage entrained with air is injected through the main injection head 627. The two sets of jets intersect, and the jets of the main injection head 627 additionally entrain oxygen-rich gas and flow to the distant sewage area. The main injection head 627 sprays radially to cover a wider sewage area, ensuring the injection distance under sufficient air supply, and entraining a higher concentration of oxygen-rich gas. During the flow process, more complete contact and fusion of water and gas are ensured, thereby increasing the dissolution rate of oxygen in water and improving the aerobic decomposition of microorganisms in sewage.

[0051] It should be explained that the continuous supply of air into the pressurization chamber 621 can ensure a higher aeration efficiency. At the same time, according to the different DO concentration requirements in the aeration tank, the input of oxygen-rich oxygen into the pump body 612 can be adjusted to meet higher DO concentration requirements.

[0052] What has been described above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and application concept of the present application, which should be covered by the protection scope of the present application.
