Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly relates to a jet oscillation catalytic oxygenation water treatment system and process. Background Art

[0002] With the rapid development of global industrialization and urbanization, sewage treatment has become a key issue in the field of environmental protection. Traditional sewage treatment technologies have gradually exposed many limitations when dealing with increasingly complex sewage components and high-standard discharge requirements.

[0003] Conventional physical sedimentation and filtration methods can only remove suspended particles and some insoluble impurities in sewage, but this method has little ability to remove the large amount of dissolved pollutants in sewage. Especially those soluble black reducing substances that cause the water body to turn black and emit a stench, such as sulfur-containing and nitrogen-containing organic compounds, the physical sedimentation method is completely helpless and cannot achieve deep purification of sewage. The biological treatment method relies on microorganisms to degrade organic matter. Facing complex sewage, the treatment efficiency is low and the depth is insufficient. It is difficult to fully oxidize and decompose complex organic matter, resulting in incomplete sewage purification. After being discharged into the river, it is extremely easy to turn black and emit a stench again, and it is impossible to achieve deep black removal and deodorization. The oxidation technology treatment method can remove the color, odor and refractory organic matter in sewage through advanced oxidation technology, but the dissolution rate of catalysts such as ozone in water is relatively low, resulting in unsatisfactory sewage treatment effects. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the present invention provides a jet oscillation catalytic oxygenation water treatment system, aiming to provide a sewage treatment system that can efficiently and deeply remove black and odor from sewage and ensure that the quality of the effluent water continuously meets the standards.

[0005] To achieve the above technical purposes, the present invention adopts the following technical solutions:

[0006] A jet oscillation catalytic oxygenation water treatment system is provided, including an aeration jet oxygenation unit, an oxygen supply unit, an ozone supply unit and a photocatalytic unit; the oxygen supply unit and the ozone supply unit are both connected to the aeration jet oxygenation unit, and the aeration jet oxygenation unit is connected to the photocatalytic unit;

[0007] The oxygen supply unit includes an oxygen generator for providing oxygen for the aeration jet oxygenation unit;

[0008] The ozone supply unit includes an ozone generator for providing ozone for the aeration jet oxygenation unit;

[0009] The aeration jet oxygenation unit includes a jet ejector, which mixes the input sewage with oxygen and ozone through the jet ejector to achieve water body oxygenation and provide sewage mixed with ozone and oxygen for the photocatalytic unit;

[0010] The photocatalytic unit includes an ultraviolet disinfector which receives sewage mixed with ozone and oxygen, and improves the oxidation-reduction potential through advanced oxidation reaction to achieve the purification of sewage.

[0011] Preferably, the oxygen supply unit further includes an oxygen storage tank, an oxygen compressor, an oxygen delivery pipeline and a flowmeter regulator, and the oxygen generator, the oxygen storage tank, the oxygen compressor, the oxygen delivery pipeline and the flowmeter regulator are connected in sequence.

[0012] Preferably, the ozone supply unit further includes an ozone storage tank, an ozone compressor, an ozone delivery pipeline and a flowmeter regulator, and the ozone generator, the ozone storage tank, the ozone compressor, the ozone delivery pipeline and the flowmeter regulator are connected in sequence.

[0013] Preferably, the ejector includes a cyclone and a nozzle, the nozzle is located at the front end of the ejector, and the output end of the nozzle is connected to the cyclone.

[0014] Preferably, the aeration jet oxygenation unit further includes a pulse oscillator which is connected to the nozzle of the ejector.

[0015] Preferably, the ozone supply unit is directly connected to the oxygen supply unit to deliver the oxygen generated by the oxygen supply unit to the ozone supply unit.

[0016] Preferably, the aeration jet oxygenation unit and the photocatalytic unit adjust the number of the aeration jet oxygenation unit and the photocatalytic unit connected to the system according to the actual sewage treatment requirements, and a plurality of the aeration jet oxygenation units are connected to a plurality of the photocatalytic units in one-to-one correspondence.

[0017] Preferably, the system further includes a hydrogen peroxide supply unit which is connected to the aeration jet oxygenation unit to mix the sewage containing oxygen and ozone with the hydrogen peroxide output by the hydrogen peroxide supply unit and then deliver the mixture to the photocatalytic unit.

[0018] The present invention also provides a water treatment process using jet oscillation catalytic oxygenation, including the following steps:

[0019] S1: Generate oxygen through the oxygen supply unit and deliver it to the aeration jet oxygenation unit;

[0020] S2: Generate ozone through the ozone supply unit and deliver it to the aeration jet oxygenation unit;

[0021] S3: Mix the input oxygen and ozone with sewage through the aeration jet oxygenation unit, and then deliver the sewage mixed with ozone and oxygen to the photocatalytic unit;

[0022] S4: In the photocatalytic unit, the redox potential is increased through advanced oxidation reaction to achieve the purification treatment of sewage.

[0023] Preferably, in step S3, the sewage mixed with ozone and oxygen is first conveyed to the hydrogen peroxide supply unit. After the sewage mixed with ozone and oxygen is remixed with hydrogen peroxide in the hydrogen peroxide supply unit, it is then conveyed to the photocatalytic unit to continue the sewage purification treatment in step S4.

[0024] Compared with the prior art, the beneficial effects produced by the present invention are as follows:

[0025] 1) With the aid of the aeration jet aeration unit, the present invention promotes the forward flow of the sewage by the ejector, promotes the water circulation, and enables the sewage to be fully mixed with sufficient oxygen and ozone, thereby enhancing the dissolution rate of ozone and oxygen in the sewage. Subsequently, it is introduced into the photocatalytic unit. Ozone, due to its strong oxidizing property, can promote the advanced oxidation reaction of organic pollutants in the water body, efficiently oxidize the soluble black reducing substances in the water body. At the same time, ozone is extremely easy to decompose and can rapidly oxidize and decompose the odor and toxic odor molecules in the water body, thus achieving the effect of deep black removal and deodorization of the water body and realizing the deep purification of sewage. At the same time, the increase in the dissolved oxygen content in the water body can effectively improve the oxygen supply of the water body, promote the biological oxidation in the water body, effectively prevent the problem of the water body discharged into the river turning black and emitting odor again, and ensure that the effluent continuously meets the standards stably.

[0026] 2) In the aeration jet aeration unit, the pulse oscillator and the ejector are innovatively combined. The oscillation force or oscillation signal generated by the pulse oscillator acts on the jet flow, causing the jet flow to oscillate. By using the oscillating jet technology, oxygen and ozone can be dissolved into the water body more quickly and evenly, further enhancing the dissolution efficiency of ozone and oxygen in the sewage, rapidly and effectively increasing the dissolved oxygen content in the water body, enhancing the ability to oxidize organic matter, and thus greatly improving the efficiency and ability of water body purification to ensure the thorough purification treatment of sewage.

[0027] 3) When dealing with scenarios where the sewage volume is extremely large, such as the black removal and deodorization of a rainwater pumping station, the treatment water volume can reach up to several thousand tons per hour, and at this time, the ozone concentration supply is insufficient. The present invention adds a hydrogen peroxide supply unit to the treatment system. Hydrogen peroxide has extremely strong oxidizing property. Adding hydrogen peroxide to the sewage can reduce the dependence on the dissolved ozone concentration in the water, and at the same time, the synergistic effect of ozone and hydrogen peroxide can strengthen the oxidation and decomposition of sewage, improving the effect and rate of sewage purification.

[0028] 4) In practical application scenarios, the present invention has excellent flexibility and scalability. It can flexibly adjust the number of aeration jet oxygenation units, photocatalysis units and other units connected to the system according to the actual sewage treatment requirements. By connecting multiple aeration jet oxygenation units and multiple photocatalysis units in one-to-one correspondence, multiple lines are realized to process sewage in parallel, improving the sewage treatment efficiency and meeting the diverse needs of sewage treatment of different scales.

[0038] Example 1

[0039] The following is combined with Figures 1-4 to further elaborate on the present invention in detail.

[0040] The embodiment of the present invention provides a jet oscillation catalytic oxygenation water treatment system, which includes an aeration jet oxygenation unit, an oxygen supply unit, an ozone supply unit, and a photocatalytic unit; the oxygen supply unit and the ozone supply unit are both connected to the aeration jet oxygenation unit, and the aeration jet oxygenation unit is connected to the photocatalytic unit;

[0041] The oxygen supply unit includes an oxygen generator for providing oxygen for the aeration jet oxygenation unit;

[0042] The ozone supply unit includes an ozone generator for providing ozone for the aeration jet oxygenation unit;

[0043] The aeration jet oxygenation unit includes a jet ejector, which mixes the input sewage with oxygen and ozone through the jet ejector to achieve water body oxygenation and provide sewage mixed with ozone and oxygen for the photocatalytic unit;

[0044] The photocatalytic unit includes an ultraviolet disinfection device, which receives the sewage mixed with ozone and oxygen and improves the oxidation-reduction potential through advanced oxidation reaction to achieve the purification of sewage.

[0045] Among them, the advanced oxidation reaction refers to a process of using strongly oxidizing free radicals to degrade organic pollutants. Its core is to generate a large number of hydroxyl free radicals through the action of catalysts, radiation, or oxidants. These free radicals can react with organic pollutants through addition, substitution, electron transfer, etc., and finally degrade the organic matter into carbon dioxide, water, and other mineral salts. The advanced oxidation technology has the characteristics of fast reaction speed, wide application range, and high treatment efficiency.

[0046] Through the aeration jet oxygenation unit of the present invention, sewage is promoted to be fully mixed with sufficient oxygen and ozone, and then introduced into the photocatalysis unit. Ozone, due to its strong oxidizing property, can promote the advanced oxidation reaction of organic pollutants in water, efficiently oxidize soluble black reducing substances in water. At the same time, ozone is extremely easy to decompose and can rapidly oxidize and decompose odor and toxic odor molecules in water, thereby achieving the effect of deep black removal and deodorization of water and realizing the deep purification of sewage. At the same time, the increase in dissolved oxygen in water can effectively improve the oxygen supply in water, promote the biological oxidation in water, effectively prevent the problem of the water discharged into the river turning black and emitting odor again, and ensure that the effluent continuously meets the standards stably.

[0047] Example 2

[0048] This example is further optimized on the basis of Example 1. The difference from Example 1 is as follows:

[0049] In this example, in addition to the oxygen generator, the oxygen supply unit further includes an oxygen compressor, an oxygen storage tank, an oxygen delivery pipeline, and a flowmeter regulator. The oxygen generator, the oxygen storage tank, the oxygen compressor, the oxygen delivery pipeline, and the flowmeter regulator are connected in sequence. The oxygen generator converts the inhaled air into pure oxygen and stores it in the oxygen storage tank. After being compressed by the oxygen compressor, the oxygen is transported through the oxygen delivery pipeline to the aeration jet oxygenation unit, and the oxygen output is controlled by the flowmeter regulator.

[0050] In this example, in addition to the ozone generator, the ozone supply unit further includes an ozone compressor, an ozone storage tank, an ozone delivery pipeline, and a flowmeter regulator, etc. The ozone generator, the ozone storage tank, the ozone compressor, the ozone delivery pipeline, and the flowmeter regulator are connected in sequence. The ozone generated by the ozone generator is stored in the ozone storage tank. After being compressed by the compressor, the ozone is transported through the delivery pipeline to the aeration jet oxygenation unit, and the ozone output is controlled by the flowmeter regulator.

[0051] In this example, the aeration jet oxygenation unit includes a jet ejector and a sewage delivery pipeline. Among them, the externally connected sewage is input into the aeration jet oxygenation unit through the sewage delivery pipeline. An air inlet 1 is provided on the sewage delivery pipeline. A high-speed liquid flow is generated by the jet ejector, and oxygen and ozone are sucked in from the air inlet 1 by using the negative pressure generated by the high-speed water flow, so that oxygen, ozone and water are fully mixed, and then transported to the photocatalysis unit through the sewage delivery pipeline.

[0052] In this embodiment, the ejector mainly includes a cyclone 3 and a nozzle 4. The nozzle 4 is located at the front end of the ejector, and the output end of the nozzle 4 is connected to the cyclone 3. The fluid passes through the nozzle 4 and the cyclone 3 of the ejector in sequence. The nozzle 4 is the most critical part of the ejector, which can convert the input energy into high-speed flow energy. The nozzle 4 usually adopts a convergent structure, that is, gradually shrinking from a large diameter to a small diameter to increase the flow rate and flow volume, so that the liquid is ejected at a high speed to generate a jet. The cyclone 3 is connected to the nozzle 4, and the rotation of the liquid is controlled by the cyclone 3. The swirling action can improve the mixing efficiency of water and gas, thereby improving the overall dissolved oxygen of the water body after confluence.

[0053] In this embodiment, the ultraviolet sterilizer in the photocatalytic unit may specifically adopt a flow-through pipeline ultraviolet sterilizer.

[0054] Embodiment 3

[0055] This embodiment is further optimized on the basis of Embodiment 2. The difference from Embodiment 2 is as follows:

[0056] In the further optimized embodiment, the aeration jet oxygenation unit further includes a pulse oscillator 2, and the pulse oscillator 2 is connected to the nozzle of the ejector. In a specific implementation, the pulse oscillator 2 can be a mechanical pulse oscillation device, which generates an oscillation force through the reciprocating motion of mechanical components; the electronic pulse oscillation device generates an oscillation signal by periodically changing the magnitude and direction of current or voltage. The oscillation force or oscillation signal generated by the pulse oscillator 2 acts on the jet flow, causing the jet flow to oscillate. During the diffusion process of oxygen and ozone into the water body, the oscillation effect of the oscillating jet will increase the velocity and flow volume of the jet, so that the velocity and flow volume of the jet flow will be greater than that of the ordinary jet, thereby generating a stronger impact force or jetting effect. This improves the oxygenation performance of the water body. The specific effects are as follows: The self-excited oscillation shear field makes the bubbles smaller and the gas-liquid contact area larger; the gas-liquid contact surface changes rapidly under the oscillation action, accelerating the renewal of the liquid film. The intense turbulence and shear brought by the shear field enhance the convective diffusion ability of the water body, and the gas and liquid are fully mixed; the pulsed jet increases the outflow pressure and velocity, enhances the convective ability of the water body, expands the service area, and reduces the possibility of bubble coalescence.

[0057] In the aeration jet oxygenation unit of the present invention, the pulse oscillator 2 and the ejector are innovatively combined. The oscillation force or oscillation signal generated by the pulse oscillator 2 acts on the jet flow, causing the jet flow to oscillate. The oscillating jet technology is used to make oxygen and ozone dissolve into the water body more quickly and evenly, rapidly and effectively improving the dissolved oxygen content of the water body, enhancing the ability to oxidize organic matter, and thus greatly improving the efficiency of water body purification, ensuring that the sewage is thoroughly purified.

[0058] In the specific implementation process, an aeration and oxygenation experiment can be carried out on small-volume sewage to calculate the gas concentration and aeration time under the current water volume. On this basis, considering the water quality of different sewage comprehensively, the aeration volume that can be compatible up and down is deduced. At the same time, for the aeration method, the aeration effects of various aeration methods are respectively tested, and finally, oscillating jet aeration with higher aeration efficiency and better water body dispersion is selected.

[0059] In a further optimized embodiment, the ozone supply unit is directly connected to the oxygen supply unit to transport the oxygen generated by the oxygen supply unit to the ozone supply unit. In the specific implementation, oxygen can also be transported to the ozone generator through an oxygen compressor, an oxygen storage tank, and an oxygen transport pipeline. By using oxygen as the gas source for producing ozone, a higher ozone concentration can be generated.

[0060] In a further optimized embodiment, the system further includes a hydrogen peroxide supply unit. The hydrogen peroxide supply unit is connected to the aeration jet oxygenation unit to mix the sewage containing oxygen and ozone with the hydrogen peroxide output by the hydrogen peroxide supply unit and then transport it to the photocatalytic unit. In the specific implementation, the hydrogen peroxide supply unit includes a hydrogen peroxide storage tank and a hydrogen peroxide transport pipeline. The hydrogen peroxide in the hydrogen peroxide storage tank is mixed with the sewage through the hydrogen peroxide pipeline.

[0061] When dealing with scenarios where the sewage volume is extremely large, such as the elimination of blackening and deodorization in a rainwater pumping station, the treatment water volume can reach up to thousands of tons per hour. At this time, the ozone concentration supply is insufficient. The present invention adds a hydrogen peroxide supply unit to the treatment system. After the sewage is mixed with hydrogen peroxide for the second time, it is then transported to the photocatalytic unit for sewage purification. Hydrogen peroxide has strong oxidizing properties. Adding hydrogen peroxide to the sewage can reduce the dependence on the dissolved ozone concentration in the water. At the same time, the synergistic effect of ozone and hydrogen peroxide can strengthen the oxidation and decomposition of sewage, improving the effect and rate of sewage purification.

[0062] Example 4

[0063] In the actual application scenario of the jet oscillation catalytic oxygenation water treatment system of the present invention, the present invention has excellent flexibility and scalability. It can flexibly adjust the number of aeration jet oxygenation units, photocatalytic units, and other units connected to the system according to the actual sewage treatment requirements, meeting the diverse needs of sewage treatment of different scales.

[0064] Combined with Figures 1-3 As shown, in this embodiment, the jet oscillation catalytic oxygenation water treatment system includes 3 aeration jet oxygenation units, 3 photocatalytic units, an ozone supply unit, an oxygen supply unit, and a hydrogen peroxide supply unit. The multiple aeration jet oxygenation units are connected to the multiple photocatalytic units in one-to-one correspondence to realize parallel processing of sewage on multiple lines, improving the efficiency of sewage treatment.

[0065] For each aeration jet oxygenation unit, the number and combination mode of the pulse oscillator 2 and the jet ejector can also be adjusted according to actual requirements. In this embodiment, each aeration jet oxygenation unit consists of 8 pulse oscillators 2 and 4 jet ejectors, that is, each jet ejector corresponds to 2 pulse oscillators 2, so as to ensure the high-efficiency and stability of the aeration jet oxygenation process. The photocatalytic unit is composed of 28 flow-through pipe ultraviolet disinfectors, which provide sufficient ultraviolet radiation conditions for the photocatalytic reaction and help the sewage purification reaction proceed fully.

[0066] Embodiment 5

[0067] The embodiment of the present invention provides a water treatment process using jet oscillation catalysis for oxygenation, including the following steps:

[0068] S1: Generate oxygen through the oxygen supply unit and transport it to the aeration jet oxygenation unit;

[0069] S2: Generate ozone through the ozone supply unit and transport it to the aeration jet oxygenation unit;

[0070] S3: Mix the input oxygen and ozone with sewage through the aeration jet oxygenation unit, and then transport the sewage mixed with ozone and oxygen to the photocatalytic unit;

[0071] S4: Increase the oxidation-reduction potential through advanced oxidation reaction in the photocatalytic unit to achieve the purification treatment of sewage.

[0072] In a further optimized embodiment, in step S3, the sewage mixed with ozone and oxygen is first transported to the hydrogen peroxide supply unit. After the sewage mixed with ozone and oxygen is mixed with hydrogen peroxide again in the hydrogen peroxide supply unit, it is then transported to the photocatalytic unit to continue the sewage purification treatment in step S4.

[0073] The above are all preferred embodiments of the present invention. The protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
