Abstract
Description
Technical Field
[0001] This application relates to the technical field of water purification, and in particular to a suspended solidified microbial purification device. Background Technology
[0002] Solidified microbial colonies are currently the most common wastewater treatment technology. It primarily uses high-tech methods to "dormantize" selected dominant microorganisms within a carrier. Specifically optimized microorganisms include combinations of over ten types such as photosynthetic bacteria, nitrifying bacteria, thiobacilli, red bacteria, and polyaerobic bacteria, significantly improving treatment efficiency and scope. Besides efficiently decomposing COD, BOD, and ammonia nitrogen, it can also decompose high-molecular-weight chemical substances without producing organic sludge or odor. Carrier-based solidified microbial technology boasts advantages such as simple operation (requiring minimal personnel management) and easy commissioning, earning it the title of the world's most "foolproof" wastewater treatment technology from industry experts. Its overall treatment cost is 30-60% lower than the activated sludge process, making it the world's lowest-cost technology.
[0003] In related technologies, solidified microorganisms are generally placed at the bottom of the water to increase the concentration of microorganisms in the water. Through the metabolic action of microbial colonies, organic pollutants can be purified, suspended solids in the water can be removed, and the water transparency can be improved.
[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: First, directly fixing and placing solidified microorganisms on the bottom of the water body is not conducive to the expansion of microorganisms into the water body; second, the activity level of microbial colonies is not high, and the purification effect needs to be improved. Summary of the Invention
[0005] In order to provide the content and activity of microbial colonies in water, this application provides a suspended solidified microbial purification device.
[0006] This application provides a suspended solidified microbial purification device, which adopts the following technical solution: A suspended solidified microbial purification device includes a purification chamber disposed on the bottom of the water, solidified microbial colonies disposed in the purification chamber, and an aeration pipe inserted into the purification chamber, wherein the purification chamber has several through holes.
[0007] By adopting the above technical solution, when oxygen is introduced into the purification chamber through the aeration pipe, the increase in oxygen concentration will enhance the activity of solidified microorganisms, thereby improving their metabolic efficiency. The solidified microorganisms and their produced substances can enter the water body through the pores, thereby improving the purification effect on the water body.
[0008] Optionally, a spherical cover is provided on the outside of the solidified microbial colony, and the surface of the spherical cover is provided with a plurality of through holes.
[0009] By employing the above technical solution, a spherical cover is placed on the outside of the solidified microbial colony. When oxygen is introduced, the spherical cover continuously tumbles, causing the solidified microorganisms to collide with the inner wall of the spherical cover. This makes it easier for the outer walls of the solidified microorganisms to detach and enter the purification chamber through the perforations on the spherical cover, and subsequently into the water. By setting up the spherical cover, the rate at which the solidified microbial colonies enter the water can be further accelerated, and their metabolic activity can be improved.
[0010] Optionally, the material density of the spherical cover is less than 1 g / cm³. 3 .
[0011] By adopting the above technical solution, when the density of the sphere is less than that of water, the tumbling effect of the sphere in the purification chamber can be further improved.
[0012] Optionally, the purification chamber has an inclined outer wall, and the through hole is formed on the outer wall.
[0013] By adopting the above technical solution and setting the outer wall at an angle, the microorganisms in the purification chamber can diffuse outwards and upwards, thereby improving the uniformity of microbial colony diffusion.
[0014] Optionally, there are four outer walls, and the purification chamber is in the shape of a four-sided pyramid.
[0015] By adopting the above technical solutions, the microbial colony can be spread more evenly.
[0016] Optionally, the purification chamber is provided with a first culture bed, on which a plurality of first attachment elements for attaching microbial colonies are densely arranged.
[0017] By adopting the above technical solution, the first cultivation bed provides an environment for microbial colonies to inhabit and reproduce. Specifically, multiple first attachment elements maximize the specific surface area of the first cultivation bed, thereby providing a larger habitat.
[0018] Optionally, the purification chamber is equipped with a carbon fiber culture bed, on which multiple second attachment devices for microbial colonies to attach are densely arranged.
[0019] By adopting the above technical solution, carbon fiber material itself has a large specific surface area, which can provide a large area of habitat and reproduction space for microbial colonies.
[0020] Optionally, a buoy is provided on the first culture bed, the density of which is less than that of water, and the first culture bed is suspended in the water.
[0021] By adopting the above technical solution and setting up buoys, the first culture bed can be suspended in the water, thereby providing a better habitat for microbial colonies.
[0022] Optionally, a plurality of purification chambers are provided, and a connecting pipe is provided between two adjacent purification chambers. The aeration pipe is connected in series through all purification chambers, and the aeration pipe has a plurality of air outlets, with each purification chamber corresponding to at least one air outlet.
[0023] Optionally, a fixing rod is installed inside the purification chamber, and the bottom of the fixing rod is pre-embedded in the mud at the bottom of the water.
[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. When oxygen is introduced into the purification chamber through the aeration pipe, the increase in oxygen concentration will enhance the activity of solidified microorganisms, thereby improving their metabolic efficiency. The solidified microorganisms and their products can enter the water body through the pores, thereby improving the purification effect on the water body. 2. By placing a spherical cover outside the solidified microbial colony, the cover will continuously tumble when oxygen is introduced. The solidified microorganisms will collide with the inner wall of the cover, making it easier for their outer walls to detach and enter the purification chamber through the perforations in the cover, thus entering the water. The spherical cover further accelerates the rate at which the solidified microbial colony enters the water and enhances their metabolic activity. 3. The first culture bed provides an environment for microbial colonies to inhabit and reproduce. Multiple first attachment elements maximize the specific surface area of the first culture bed, thus providing a larger habitat. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0030] This application discloses a suspended solidified microbial purification device.
[0031] Reference Figure 1-3 The suspended solidified microbial purification device includes a purification chamber 1 located at the bottom of the water, solidified microbial colonies 2 located within the purification chamber 1, and an aeration pipe 3. In this embodiment, the purification chamber 1 is made of metal and therefore sinks to the bottom. The purification chamber 1 has several through holes 11 to allow the solidified microorganisms and their produced substances to enter the water. In this embodiment, several purification chambers 1 are provided, and a connecting rod 6 is welded and fixed between adjacent purification chambers 1. The aeration pipe 3 passes through all purification chambers 1 in series, and the aeration pipe 3 has several air outlets, with each purification chamber 1 corresponding to at least one air outlet.
[0032] The solidified microbial colony 2 is composed of several active microorganisms, such as photosynthetic bacteria, nitrifying bacteria, thiobacilli, red bacteria, and polyaerobic bacteria. It can decompose high-molecular-weight chemical substances, adsorb and precipitate metals in the water, improve water transparency, and inhibit algae growth. For example, Aspergillus fungi can secrete a scavenging substance with antibacterial properties, which can control the growth of microalgae in the water. The cultivation and formation of the solidified microbial colony 2 is existing technology, and the details of the internal structure of the solidified microbial colony 2 will not be further described in this embodiment.
[0033] Aeration pipe 3 is connected to an air pump to introduce oxygen, thereby introducing air into purification chamber 1. This increases the activity and metabolic rate of microbial colonies, further improving water purification efficiency.
[0034] A spherical cover 21 is provided on the outer side of the solidified microbial colony 2, and the spherical cover 21 has several perforations 22. The solidified microorganisms and their products can enter the purification chamber 1 through the perforations 22, and then enter the water. In this embodiment, the spherical cover 21 is made of a lightweight material with a density much less than 1 g / cm³. 3 That is, the density is much smaller than that of water. When the air pump controls the aeration pipe 3 to introduce oxygen into the purification chamber 1, the spherical cover 21 will continuously roll under the action of water buoyancy and gas flow. This causes the outer colonies of solidified microorganisms to continuously collide and rub against the inner wall of the spherical cover 21, making it easier for them to detach and enter the purification chamber 1 and the interior of the water, thereby increasing the content of microbial colonies in the water.
[0035] The purification chamber 1 has an inclined outer wall, with through holes 11 vertically formed on the outer wall. When solidified microorganisms and their produced substances pass through the through holes 11, they have a tendency to move outwards and upwards, thus allowing the solidified microorganisms and their produced substances to disperse better in the water. In this embodiment, there are four inclined outer walls, and the purification chamber 1 is generally in the shape of a regular square pyramid, which allows the solidified microorganisms and their produced substances to disperse more evenly in all directions, while also moving upwards. A fixing rod 12 is vertically inserted through the center of the purification chamber 1, and the bottom of the fixing rod 12 is pre-embedded in the underwater mud.
[0036] The suspended solidified microbial purification device also includes a first cultivation bed 4, which provides a habitat for microbial colonies. The first cultivation bed 4 is elongated and has buoys 42 at its ends to keep it vertically suspended in the water. Multiple first attachments 41 are provided on the first cultivation bed 4. In this embodiment, the first attachments 41 are hair-like to increase the specific surface area of the first cultivation bed 4. Microbial colonies attach to the first attachments 41, and the oxygen content of the water is increased by the aeration device, thereby improving the metabolic and reproductive efficiency of the microbial colonies. The first cultivation bed 4 also provides a good shelter, reproduction, and habitat environment for the microbial colonies. When the solidified microorganisms in the purification chamber 1 are activated, the microbial concentration around the water can reach 500 million CFU / ml. The first cultivation bed 4 can be installed inside the purification chamber 1 or fixed to the connecting rod 6; in this embodiment, it is fixed to the connecting rod 6.
[0037] In another embodiment, the first attachment member 41 is disc-shaped, and several first attachment members 41 are vertically spaced along the length of the first culture bed 4. The microbial community can be arranged between two adjacent first attachment members 41.
[0038] The purification chamber 1 is also equipped with a carbon fiber cultivation bed 5, which has multiple second attachments 51 extending from it to increase the specific surface area of the cultivation bed. Carbon fiber itself has a low density and a large specific surface area, providing a larger habitat for microorganisms, and it can also suspend in water. When the water flow is fluctuating, the microbial colonies can also spread more effectively into the water.
[0039] The implementation principle of the suspended solidified microbial purification device in this application embodiment is as follows: When air is blown into the aeration pipe 3 by an air pump, the spherical cover 21 continuously agitates within the purification chamber 1, thereby increasing the activity of the solidified microbial colonies 2 and the density of aquatic microbial colonies in the water. The first cultivation bed 4 and the carbon fiber cultivation bed 5 provide a favorable environment for the habitation and reproduction of microorganisms, promoting the proliferation of microbial colonies.
[0040] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
