Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment devices, and in particular to an algae-bacteria symbiotic reactor and a treatment system for sewage treatment. Background Art

[0002] Animal husbandry has made great contributions to ensuring the supply of meat, eggs and milk for people. However, with the expansion of the scale of animal husbandry production and the improvement of its intensiveness, the corresponding aquaculture wastewater problem has gradually become one of the issues that cannot be ignored in subsequent treatment.

[0003] The treatment of aquaculture wastewater is different from the treatment of other sewage. It has distinct characteristics: it has a lower carbon-nitrogen ratio, contains a higher amount of organic matter, and has a strong odor, especially the characteristic odor of livestock and poultry excrement. Therefore, simply using other types of sewage treatment processes to treat this type of sewage cannot effectively solve its pollutant treatment problems. In particular, odors spread quickly, over long distances, and have complex components, making them extremely difficult to remove. Moreover, compared with the degradation processes of water pollutants such as COD, BOD, and ammonia nitrogen, odors have received relatively little attention, and the treatment technology is not yet mature, which restricts the research and development and application of deodorization technology. Therefore, exploring efficient treatment methods for odors in aquaculture wastewater has become one of the key points in solving aquaculture pollution.

[0004] Microbial-mediated wastewater resource utilization technology has shown great charm and application value with its advantages of economy, environmental protection, and strong operability. In particular, the algae-bacteria symbiotic system is established by combining the removal of nutrients such as nitrogen and phosphorus in sewage with the ability of bacteria to degrade organic matter. Algae release oxygen through photosynthesis to supply aerobic microorganisms for metabolic activities, while aerobic microorganisms degrade organic matter to produce CO2, nitrogen, phosphorus, potassium, etc., which provide the carbon source and nutrition required for algae growth. It can effectively solve the problems of denitrification and phosphorus removal and organic matter removal in livestock and poultry breeding sewage, prevent eutrophication of water bodies and soil pollution, and has positive practical significance for improving the environmental quality in rural areas and promoting sustainable development of regional economy.

[0005] For this reason, corresponding treatment devices for algae-bacteria symbiosis have come into being. Traditional algae-bacteria symbiosis reactors have some problems. For example, algae often have insufficient light, resulting in a small proportion, and the final dissolved oxygen content of the water body is relatively small. When there is a problem of insufficient dissolved oxygen, bacteria undergo anoxic decomposition, resulting in poor sewage treatment effect. Utility Model Content

[0006] The purpose of the present application is to provide an algae-bacteria symbiotic reactor and a treatment system for sewage treatment to solve at least one of the above-mentioned technical problems.

[0007] In order to solve the above technical problems, the present application provides an algae-bacteria symbiotic reactor and a treatment system for sewage treatment. In a first aspect, the present application provides an algae-bacteria symbiotic reactor for sewage treatment, comprising a first treatment device, wherein the first treatment device comprises a first barrel body having an accommodating space;

[0008] A light-emitting assembly is provided in the first barrel, the light-emitting assembly includes a columnar main body connected to the bottom of the first barrel, and a bifurcated portion extending radially along the main body, the bifurcated portion is arranged in multiple layers along the length direction of the main body, and each layer is provided with a plurality of the bifurcated portions;

When placed outdoors, it can be exposed to sunlight during the day and the light-emitting component can be turned on or off; and the light-emitting component can be turned on at night. The present solution sets the light-emitting component inside the barrel body, which can serve as a part of the attachment point of the algae-bacteria symbiont. Compared with the state in which the general reactor is completely empty, the present solution provides a part of the attachment point for the algae-bacteria symbiont, which is conducive to the subsequent continuous use and reduces the problem of excessive loss of the algae-bacteria symbiont after the sewage flows; secondly, emitting light from the inside can make the light source more uniform, and uniform light emission is conducive to promoting the growth of algae and improving its culture efficiency, thereby alleviating the problem of imbalance in the ratio of algae and bacteria, effectively promoting the growth of algae, and increasing the dissolved oxygen rate of sewage in the barrel body, thereby promoting aerobic decomposition bacteria to fully decompose pollutants.

[0024] A second water inlet is provided above the second barrel body, and a second water outlet is provided below the second barrel body. The first water outlet is connected to the second water inlet; and a second air outlet is provided above the second barrel body.

[0025] In the above implementation process, the sewage first passes through the first treatment device and then enters the second treatment device. In the first treatment device, the light-emitting components are used to achieve a better balance of algae-bacteria symbiosis, and the various pollution indicators of the sewage are also improved to a certain extent after preliminary treatment. After entering the second treatment device, there is no need to use additional light-emitting components. Instead, a large number of spherical or block fillers are used to provide a large number of attachment points for algae and bacteria, so as to retain the algae-bacteria symbiosis as much as possible and prepare for subsequent recycling. This scheme can effectively ensure the balance of algae and bacteria through the cooperation of the first treatment device and the second treatment device, while improving the sewage treatment efficiency and the number of subsequent recycling times.

[0026] Preferably, it further comprises a first filter assembly, wherein the first filter assembly is arranged to be connected to the first water inlet;

[0027] The first filter assembly comprises a first box body, a third water inlet and a third water outlet are respectively provided at two ends of the first box body, and a plurality of first filter screens are provided in the first box body along the water flow direction;

[0029] Preferably, a second filter screen is provided at the second water outlet;

[0030] In the above implementation process, by further arranging a second filter at the second water outlet, the water discharged from the second treatment device can be filtered again to further improve the purification effect.

[0044] Example

[0045] Microbial-mediated wastewater resource utilization technology has shown great charm and application value with its advantages of economy, environmental protection, and strong operability. In particular, the algae-bacteria symbiotic system is established by combining the removal of nutrients such as nitrogen and phosphorus in sewage with the ability of bacteria to degrade organic matter. Algae release oxygen through photosynthesis to supply aerobic microorganisms for metabolic activities, and aerobic microorganisms degrade organic matter to produce CO2, nitrogen, phosphorus, potassium, etc., which provide the carbon source and nutrition required for algae growth. It can effectively solve the problems of denitrification and phosphorus removal and organic matter removal of livestock and poultry breeding sewage, prevent eutrophication of water bodies and soil pollution, and have positive practical significance for improving the environmental quality of rural areas and promoting sustainable development of regional economy. For this reason, corresponding treatment devices for algae-bacteria symbiosis have emerged. Traditional algae-bacteria symbiotic reactors have some problems, such as algae often have insufficient light, resulting in a small proportion, and the dissolved oxygen content of the water body is relatively small. When the problem of insufficient dissolved oxygen occurs, bacteria undergo anoxic decomposition, resulting in poor sewage treatment effect; In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0046] For details, see Figure 1-3 , this embodiment provides an algae-bacteria symbiotic reactor for sewage treatment, comprising a first treatment device, the first treatment device comprising a first barrel body 11 formed with an accommodating space;

[0047] Furthermore, a light emitting assembly 20 is provided in the first barrel 11, and the light emitting assembly 20 includes a columnar main body 21 connected to the bottom of the first barrel 11, and a forked portion 22 extending radially along the main body 21, and the forked portion 22 is arranged in multiple layers along the length direction of the main body 21, and each layer is provided with a plurality of forked portions 22;

[0048] A power supply assembly 15 is provided at the outer bottom of the first barrel 11, and the power supply assembly 15 is electrically connected to the light emitting assembly 20;

[0049] Furthermore, a first water inlet 13 is provided on the side wall near the upper end of the first barrel body 11 , a first water outlet 14 is provided on the side wall near the lower end, and a first air outlet 12 is provided at the top end of the first barrel body 11 .

[0050] In the above scheme, sewage enters the first barrel body 11 from the water inlet of the first barrel body 11, and the algae-bacteria symbiont can be introduced from the first air outlet 12, or attached to the outer wall of the light-emitting component 20 in the initial state to wait for the introduction of sewage; the first barrel body 11 can be placed indoors or outdoors according to actual conditions. When placed outdoors, it can be exposed to sunlight during the day and the light-emitting component 20 can be turned on or off to cooperate; and the light-emitting component 20 can be turned on at night. This scheme sets the light-emitting component 20 inside the barrel body, which can be used as an attachment point for part of the algae-bacteria symbiont. Compared with the state in which the general reactor is completely empty, this scheme provides a part of the attachment point for the algae-bacteria symbiont, which is conducive to the subsequent continuous use and reduces the problem of excessive loss of the algae-bacteria symbiont after the sewage flows; secondly, emitting light from the inside can make the light source more uniform, and uniform light emission is conducive to promoting the growth of algae and improving its cultivation efficiency, thereby alleviating the problem of imbalance in the ratio of algae and bacteria, effectively promoting the growth of algae, and improving the dissolved oxygen rate of sewage in the barrel body, thereby promoting aerobic decomposition bacteria to fully decompose pollutants.

[0051] It should be noted that the connection method between the power supply component 15 and the built-in light-emitting body is a relatively mature technology in the prior art, and the relevant waterproof measures are also easily obtained by technical personnel in this field from the prior art, so this scheme does not further elaborate on the specific structure of this part.

[0052] For details, see Figure 2 The main body 21 and the bifurcated portion 22 are respectively composed of an attachment layer 24, a light diffusion layer 25 and a light source layer from the outside to the inside;

[0053] Furthermore, the light source layer is provided with a light emitting member 26 electrically connected to the power source assembly 15, and the attachment layer 24 is suitable for algae and fungi to attach;

[0054] In the above scheme, the attachment layer 24 can provide attachment points for algae and fungi, thereby improving the adhesion strength of the algae-fungus symbiosis, reducing its loss rate, and promoting recycling; and the light emitted by the light source layer can improve the uniformity of light illumination through the scattering effect of the scattering layer 25, which is beneficial to improving the growth efficiency of algae and alleviating the imbalance problem of algae and fungi.

[0055] It is understandable that in some embodiments, in the sewage treatment process, not only the internal light source may be used, but a corresponding light source may also be installed on the outside of the first barrel 11, and the specific adjustment may be made according to actual needs.

[0056] In some of the embodiments, the light emitting element 26 may be an LED light strip or other light source that can emit light.

[0057] Specifically, the attachment layer 24 is made of a transparent polyurethane material;

[0058] In the above scheme, the transparent polyurethane material can firstly provide a good attachment point for algae and fungi, and secondly, the material itself has strong corrosion resistance and can ensure a certain service life.

[0059] Specifically, the light diffusion layer 25 is made of transparent epoxy resin, and a plurality of glass beads are embedded in the light diffusion layer 25;

[0060] In the above scheme, the epoxy resin has good waterproof performance, and glass beads are embedded in it to promote the scattering of light.

[0061] Specifically, a branch portion 23 is formed on the bifurcated portion 22 and extends in a direction away from the bifurcated portion 22 , and the branch portion 23 includes an adhesion layer 24 and a light diffusion layer 25 ;

[0062] In the above scheme, a branch portion 23 is further provided on the bifurcated portion 22 to further increase the attachment points of algae and fungi. Meanwhile, there is no need to provide a light source layer, but light scattering can be achieved through the interconnected light scattering layers 25.

[0063] Specifically, this embodiment also provides an algae-bacteria symbiotic treatment system for sewage treatment, comprising any of the first treatment devices described above, and also comprising a second treatment device;

[0064] For details, see Figure 1 , the second processing device includes a second barrel body 31 formed with an accommodating space;

[0065] Furthermore, a plurality of spherical or block-shaped fillers 35 are filled in the second barrel 31, and the fillers are made of polyurethane material, and the outer wall of the fillers is suitable for attaching the algae-bacteria symbiosis;

[0066] Specifically, a second water inlet 33 is provided above the second barrel body 31 , a second water outlet 34 is provided below the second barrel body 31 , and the first water outlet 14 and the second water inlet 33 are connected; a second air outlet 32 ​​is provided above the second barrel body 31 .

[0067] In the above scheme, the sewage first passes through the first treatment device and then enters the second treatment device. In the first treatment device, the light-emitting component 20 is used to achieve a better balance of algae-bacteria symbiosis, and the various pollution indicators of the sewage are also improved to a certain extent after preliminary treatment. After entering the second treatment device, there is no need to use the additional light-emitting component 20. Instead, a large number of spherical or block fillers 35 are used to provide a large number of attachment points for algae and bacteria, so as to retain the algae-bacteria symbiosis as much as possible and prepare for subsequent recycling. This scheme can effectively ensure the balance of algae and bacteria through the cooperation of the first treatment device and the second treatment device, while improving the sewage treatment efficiency and the number of subsequent recycling times.

[0070] In the above scheme, when sewage enters the first barrel body 11, it first passes through the filtering effect of the first filter component 50 to remove some large particle impurities, which can not only effectively improve the quality of subsequent sewage treatment, but also prevent excessive impurities from affecting the divergence of light in the first barrel body 11.

[0071] Specifically, a second filter screen 40 is provided at the second water outlet 34;

[0072] In the above solution, by further arranging a second filter screen 40 at the second water outlet 34, the water discharged from the second treatment device can be filtered again, thereby further improving the purification effect.
