Description

Technical Field

[0001] The present invention relates to a water pollution remediation method, and in particular to a water pollution remediation method based on microorganisms applied in the technical field related to sewage treatment. Background Art

[0002] Microbial technology primarily involves adding microbial agents to contaminated water bodies to regulate the composition and abundance of microbial communities, optimizing the community structure and thereby increasing the efficiency of self-purifying microorganisms in removing pollutants. Common microbial agents include groups of microorganisms primarily composed of photosynthetic bacteria, lactobacilli, and nitrifying bacteria. These microorganisms can decompose organic matter in the water, such as those released from external pollution, sediment, and algae growth, using it for their own growth and reproduction, thereby reducing algae growth and improving water quality.

[0003] In the prior art, there are generally two ways of administering biological agents. One is direct administration, such as the river water ecological restoration method disclosed in the Chinese patent specification with publication number CN101607762A; the other is slow release through a floating plate as a carrier, such as a bacterial agent and preparation method for bioremediation of oil-polluted waters disclosed in the Chinese patent specification with publication number CN103523928A. However, the bacteria in the former are easily dispersed by water flow, have a short retention time, and have a low survival rate. Although the latter can prolong the retention time of the bacterial agent and reduce the frequency of administration compared with the former, the surface pores of the carrier floating plate are easily blocked by impurities in the water body, microorganisms attached to form biofilms, etc., which affects the diffusion of bacteria and thus affects the efficiency of water body restoration. Summary of the Invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that when a carrier is used to release the bacterial agent, the surface pores of the carrier float are easily blocked, which affects the diffusion of the bacterial species and the efficiency of water body repair.

[0005] To solve the above problems, the present invention provides a method for remediating water pollution based on microorganisms, comprising the following steps: S1. First, sample the water and conduct water quality testing. Select native bacterial species and, based on the test results, add additional bacterial species targeting water pollutants. During the water quality testing, simultaneously test the water depth and design the longitudinal span of the depth diffusion carrier based on the water depth. S2. Classifying the native bacterial species and the added bacterial species into aerobic bacteria and anaerobic bacteria, and expanding and culturing the aerobic bacteria and anaerobic bacteria in the native bacterial species and the added bacterial species, respectively; S3. Mixing the expanded cultured native bacteria and aerobic bacteria from the added bacteria, and filling the mixture into the upper layer of the deep diffusion carrier; mixing the expanded cultured native bacteria and anaerobic bacteria from the added bacteria, and filling the mixture into the bottom layer of the deep diffusion carrier, wherein the deep diffusion carrier is connected to an external mobile terminal signal; S4. Deployment of in-depth diffusion carriers: S41. Multiple deep diffusion carriers are placed in the polluted water body, with an appropriate placement density selected based on the degree of pollution. The top floating discs of the deep diffusion carriers are controlled to shrink repeatedly at intervals to restore partial permeability and maintain stable release of the bacteria. S42, after each shrinking operation, the water body is stirred to cause the water body to vibrate, thereby causing some entities to form waves and hit the depth diffusion carrier; S43. After the water body fluctuates, the water body is allowed to stand for a period of time to calm down. At this time, the enzyme activity sensor at the bottom of the deep diffusion carrier is used to monitor the bacterial activity in the water body in real time. The micro-display unit is used to detect whether the outer layer of the floating plate of the deep diffusion carrier is clogged. Based on the blockage and bacterial activity, a comprehensive judgment is made as to whether a new deep diffusion carrier should be deployed to replenish the bacterial strain. S5. Sampling the water body at regular intervals, and then conducting water quality testing, and adding depth diffusion carriers based on the test results until the water quality test results meet the restoration standards and the water body restoration is completed; The in-depth diffusion carrier includes a double-layer floating plate, multiple evenly distributed biological ropes fixedly connected to the lower end of the double-layer floating plate, and multiple sinking carrier balls fixedly connected to the lower ends of the biological ropes. An enzyme activity sensor is also installed at the lower end of the double-layer floating plate. Multiple evenly distributed convergence tubes are fixedly connected to the outer end of the double-layer floating plate. Two adjacent convergence tubes are fixedly connected with two external convergence belts. The ends of the multiple convergence tubes facing the double-layer floating plate are fixedly connected with internal flushing arc strips. The multiple internal flushing arc strips are fixedly extended into the double-layer floating plate, wherein a mixed bacterial agent of anaerobic bacteria from native bacteria and added bacteria is filled in the sinking carrier ball.

[0006] In the above-mentioned microbial-based water pollution remediation method, in the deep diffusion carrier used for the delivery of the bacterial agent, through the setting of a double-layer floating disk, on the one hand, the outer interception layer can intercept larger impurities in the water body, thereby making the surface layer of the inner bacterial layer to which the bacterial agent is attached less likely to be blocked; on the other hand, it can automatically desorb some of the intercepted impurities, thereby effectively ensuring the stable release of the bacterial agent.

[0007] As a further improvement of the present application, an inner partition is fixedly connected to the inside of the convergence tube, and the inner partition is lower than the center line of the convergence tube. The connection between the inner flushing arc strip and the inner partition is located above the inner partition, and the convergence tube and the inner flushing arc strip are interconnected. The outer convergence belt is made of high elastic material.

[0008] As a further improvement of the present application, the double-layer floating plate includes an outer intercepting layer, an inner bacteria-carrying layer fixedly connected to the inside of the outer intercepting layer, and an electromagnetic core fixedly embedded in the center of the inner bacteria-carrying layer. The electromagnetic core is wrapped with an insulating waterproof layer, and the insulating waterproof layer has a built-in control center and a micro power supply. The micro power supply is used to power the electromagnetic core. A cavity is opened inside the outer intercepting layer, the inner bacteria-carrying layer is located in the cavity, and the upper and lower ends of the inner bacteria-carrying layer are not in contact with the corresponding inner walls of the cavity.

[0009] As a further improvement of the present application, the convergence tube is divided into two semi-cylindrical tube segments, and a magnetic sheet is fixedly embedded in the tube segment connected to the outer intercepting layer. The electromagnetic core generates an adsorption force on the magnetic sheet when energized, and the electromagnetic core in each longitudinal diffusion carrier has the same magnetic pole facing outward after energization.

[0010] As a further improvement of the present application, the inner bacterial carrier includes an outer variable layer and an inner carrier fixedly mounted outside the outer variable layer. The inner carrier is fixedly connected to the inner wall of the aperture ring. In step S3, a mixed bacterial agent of aerobic bacteria in the native bacterial species and the added bacterial species is filled in the pores of the outer variable layer. The inner carrier is an elastic structure. The outer variable layer and the outer intercepting layer are both porous structures, and the pore size of the outer intercepting layer is larger than that of the outer variable layer.

[0011] As a further improvement of the present application, the internal flushing arc strip includes a wrinkle-following section fixedly connected to the convergence tube, a fixed arc section fixedly connected to the wrinkle-following section, and a plurality of water spray pipes respectively fixedly connected to the lower ends of the fixed arc sections. The fixed arc section is completely located in the internal bacteria-carrying layer, the lower ends of the plurality of water spray pipes are flush with each other, and the ends of the plurality of water spray pipes pass through the cavity.

[0012] As a further improvement of the present application, the wrinkle segment is an elastic structure, the fixed arc segment is a hard structure, and along the direction away from the convergence tube: the inner diameters of the wrinkle segment and the fixed arc segment gradually decrease, and the height and diameter of the chrome-plated water spray pipe gradually decrease.

[0014] As another improved supplement to the present application, the liquid measuring float includes a hollow ball of air and a pressure sensor fixedly intercepted at the bottom of the hollow ball. Wire holes are drilled at corresponding positions of the hollow ball and the detection end of the pressure sensor. The sinking carrier ball movably passes through the wire holes and is fixedly connected to the detection end of the pressure sensor. When the pull rope is fully extended, the bottom of the liquid measuring float is just flush with the top of the convergence tube.

[0015] As another improved supplement to the present application, a photovoltaic panel is also installed on the top of the outer interception layer, which is electrically connected to the micro power supply. The photovoltaic panel is installed outside the annular light strip, which is connected to the control center signal and electrically connected to the micro power supply.

[0016] In summary, in the deep diffusion carrier used for the delivery of bacterial agents, through the setting of a double-layer floating plate, on the one hand, the outer interception layer can intercept larger impurities in the water body, thereby making the surface layer of the inner bacterial layer attached with the bacterial agent less likely to be blocked; on the other hand, it can automatically perform a wrinkling operation at regular intervals, and then directly squeeze the outer layer, so that some of the adsorbed impurities can be squeezed and desorbed; at the same time, it can also use the vibration of the water body to flush the pores of the outer interception layer from the inside to the outside, thereby effectively ensuring the connectivity between the inner bacterial layer and the water body, thereby effectively ensuring the stable release of the bacterial agent, and effectively ensuring the efficient repair of the water body; and under the action of the micro-display unit, it can also detect whether the outer layer of the floating plate of the deep diffusion carrier is blocked. When it is blocked abnormally and the bacterial agent cannot be delivered normally, the staff can promptly deliver a new deep diffusion carrier, effectively ensuring the stable progress of the water body repair process.

DETAILED DESCRIPTION

[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0020] The first implementation method: Figure 1 A method for remediating water pollution based on microorganisms is shown, comprising the following steps: S1. First, sample the water and conduct water quality testing. Select native bacterial species and, based on the test results, add additional bacterial species targeting water pollutants. During the water quality testing, simultaneously test the water depth and design the longitudinal span of the diffusion carrier based on the water depth. This effectively ensures that when the bacterial agent is added, the anaerobic bacteria can penetrate into the oxygen-free area at the bottom of the water, making it less likely for the anaerobic bacteria to be inactivated by oxygen, thereby improving the remediation effect. S2. Classifying the native bacterial species and the added bacterial species into aerobic bacteria and anaerobic bacteria, and expanding and culturing the aerobic bacteria and anaerobic bacteria in the native bacterial species and the added bacterial species respectively; S3. Mixing the expanded cultured native bacteria and aerobic bacteria from the added bacteria, and filling the mixture into the upper layer of the deep diffusion carrier; mixing the expanded cultured native bacteria and anaerobic bacteria from the added bacteria, and filling the mixture into the bottom layer of the deep diffusion carrier, wherein the deep diffusion carrier is connected to an external mobile terminal signal; S4. Deployment of in-depth diffusion carriers: S41. Multiple deep diffusion carriers are placed in the polluted water body, with an appropriate placement density selected based on the degree of pollution. The top floating discs of the deep diffusion carriers are controlled to shrink repeatedly at intervals to restore partial permeability and maintain stable release of the bacteria. S42, after each shrinking operation, the water body is stirred to cause the water body to vibrate, thereby causing some entities to form waves and hit the depth diffusion carrier; S43. After the water body fluctuates, the water body is allowed to stand for a period of time to return to calm. At this time, the enzyme activity sensor at the bottom of the deep diffusion carrier is used to detect the activity of the bacterial strain in the water body in real time. Based on the activity of the bacterial strain, it is determined whether a new deep diffusion carrier should be added to replenish the bacterial strain. S5. Sampling the water body at regular intervals, and then conducting water quality testing, and adding depth diffusion carriers based on the test results until the water quality test results meet the restoration standards and the water body restoration is completed; like Figure 2-4 The depth diffusion carrier includes a double-layer floating plate 1, a plurality of evenly distributed biological ropes 3 fixedly connected to the lower end of the double-layer floating plate 1, and a plurality of sinking carrier balls 5 respectively fixedly connected to the lower ends of the biological ropes 3. An enzyme activity sensor is also installed at the lower end of the double-layer floating plate 1. The enzyme activity sensor is a specific enzyme activity sensor for bacteria, which can effectively detect the activity of bacteria near the double-layer floating plate 1, so that the staff can timely understand the release of the bacterial agent at the double-layer floating plate 1, and it is convenient to supplement the bacteria according to the actual situation, thereby effectively ensuring the repair efficiency of the water body. The outer end of the double-layer floating plate 1 is fixedly connected to a plurality of evenly distributed convergence tubes 2, and two adjacent convergence tubes 2 are fixedly connected between two outer convergence belts 202. The plurality of convergence tubes 2 face the double-layer floating plate. One end of each of the two floating plates 1 is fixedly connected with an inner flushing arc bar 4, through which the beating force of the water body vibration can be directly utilized to flush the pores on the outer interception layer 11, so that the bottom of the two floating plates 1 can maintain a certain permeability, prolong the time of being blocked, reduce the frequency of manual recovery, and facilitate the stable delivery of the internal bacterial agent. Multiple inner flushing arc bars 4 are fixedly extended into the double-layer floating plate 1, wherein the mixed bacterial agent of the native bacterial species and the anaerobic bacteria in the added bacterial species is filled in the sinking carrier ball 5, and the sinking carrier ball 5 can also be weighted to a certain extent so that it is stably located in the deep water body, so that the depth diffusion carrier can simultaneously repair the surface aerobic area of the water body through aerobic bacteria and repair the deep layer through anaerobic bacteria, effectively ensuring the repair efficiency.

[0021] In the above-mentioned microbial-based water pollution remediation method, in the deep diffusion carrier used for the delivery of the microbial agent, through the setting of a double-layer floating disk, on the one hand, the outer interception layer 11 can intercept larger impurities in the water body, thereby making the surface layer of the inner bacterial layer 12 to which the microbial agent is attached less likely to be blocked; on the other hand, it can automatically desorb some of the intercepted impurities, thereby effectively ensuring the stable release of the microbial agent.

[0022] like Figure 5The double-layer floating plate 1 includes an outer intercepting layer 11, an inner bacteria-carrying layer 12 fixedly connected to the inner part of the outer intercepting layer 11, and an electromagnetic core 13 fixedly embedded in the center of the inner bacteria-carrying layer 12. The electromagnetic core 13 is wrapped with an insulating waterproof layer, and the insulating waterproof layer has a built-in control center and a micro power supply. The micro power supply is used to power the electromagnetic core 13. A cavity is excavated inside the outer intercepting layer 11, and the inner bacteria-carrying layer 12 is located in the cavity. The upper and lower ends of the inner bacteria-carrying layer 12 are not in contact with the corresponding inner walls of the cavity. The convergence tube 2 is divided into two semi-cylindrical tube slices, and the tube slice connected to the outer intercepting layer 11 is fixedly embedded with a magnetic sheet. When energized, the electromagnetic core 13 generates an adsorption force on the magnetic sheet. At regular intervals, the control center can control the electromagnetic core 13 to energize, thereby causing it to generate an adsorption force on the magnetic sheets in multiple convergence tubes 2. Figure 6 , so that the double-layer floating plate 1 gradually shrinks from the outside to the inside, so that some of the water inside can be squeezed out. In this process, some impurities intercepted on its surface can be washed away, achieving automatic desorption, and then the outer layer of the double-layer floating plate 1 can restore good permeability, which is convenient for the continuous release of the bacterial agent.

[0023] Moreover, the outward-facing magnetic poles of the electromagnetic core 13 in each deep diffusion carrier are the same after being energized, so that the outward-facing magnetic poles of the magnetic sheets on multiple deep diffusion carriers are also the same. When multiple deep diffusion carriers placed in the water body are close to each other, magnetic repulsion will be generated between them, making it difficult for them to gather together, thereby improving the uniformity of the distribution of multiple deep diffusion carriers in the water body and reducing the occurrence of local excessive aggregation, thereby making the water body repair more uniform and the effect better.

[0024] The inner bacterial carrier layer 12 includes an outer variable layer 121 and an inner carrier 122 fixedly mounted on the outer variable layer 121. The inner carrier 122 is fixedly connected to the inner wall of the aperture ring. In step S3, a mixed bacterial agent of aerobic bacteria from native bacterial species and added bacterial species is filled in the pores of the outer variable layer 121. The inner carrier 122 is an elastic structure. The inner carrier 122 is mainly used to increase the radial contraction amplitude of the double-layer floating plate 1 when it shrinks, so as to achieve better desorption effect of surface impurities. The outer variable layer 121 and the outer intercepting layer 11 are both porous structures, and the pore size of the outer intercepting layer 11 is larger than that of the outer variable layer 121, so that the outer intercepting layer 11 is not easily affected by the release of the bacterial agent.

[0025] Among them, the outer variable layer 121 and the sinking carrier ball 5 can be made of sodium alginate-bentonite composite microspheres, which are resistant to water erosion and can slowly release bacterial agents. Technical personnel can also choose appropriate materials according to actual needs.

[0026] like Figure 7-8, an inner baffle 201 is fixedly connected to the inside of the convergence tube 2, and the inner baffle 201 is lower than the center line of the convergence tube 2, the connection between the inner flushing arc strip 4 and the inner baffle 201 is located above the inner baffle 201, and the convergence tube 2 and the inner flushing arc strip 4 are connected to each other, the outer convergence belt 202 is made of high elastic material, the inner flushing arc strip 4 includes a wrinkle-following section 41 fixedly connected to the convergence tube 2, a fixed arc section 42 fixedly connected to the wrinkle-following section 41, and a plurality of water spray pipes 43 fixedly connected to the lower end of the fixed arc section 42, the fixed arc section 42 is completely located in the inner bacteria-carrying layer 12, the lower ends of the plurality of water spray pipes 43 are flush with each other, and the ends of the plurality of water spray pipes 43 pass through the cavity, when the water body oscillates and causes part of the waves to hit the double-layer floating plate 1, part of the water is quickly poured into the convergence tube 2, such as Figure 9 At this time, the water body researchers quickly extend along the direction of the wrinkle section 41, the fixed arc section 42 and the water spray pipe 43, so that the water can be sprayed downward from multiple water spray pipes 43, thereby achieving the effect of flushing the bottom of the outer interception layer 11 from the inside to the outside, thereby effectively assisting the pores on the electromagnetic core 13 to maintain permeability, and not easily affecting the release of the bacterial agent on the internal bacterial layer 12.

[0027] The wrinkle section 41 is an elastic structure, so that it can adapt to the wrinkling changes of the outer interception layer 11 under the extrusion of multiple convergence tubes 2. The fixed arc section 42 is a hard structure, and along the direction away from the convergence tube 2: the inner diameters of the wrinkle section 41 and the fixed arc section 42 gradually decrease, and the height and diameter of the chrome-plated water spray pipe 43 gradually decrease. The gradual decrease in the aperture can accumulate a certain amount of force for the water sprayed from the water spray pipe 43, so that it can be sprayed at a relatively higher speed, thereby making it have a better flushing effect on the pores at the bottom of the outer interception layer 11, so that some of the intercepted impurities are separated from the outer interception layer 11 under the action of the flushing force.

[0028] In summary, in the deep diffusion carrier for the delivery of bacterial agents, through the setting of the double-layer floating plate, on the one hand, the outer interception layer 11 can intercept larger impurities in the water body, thereby making the surface layer of the inner bacterial layer 12 attached with the bacterial agent less likely to be blocked; on the other hand, it can automatically perform a shrinkage operation at regular intervals, thereby directly squeezing the outer layer so that some of the adsorbed impurities can be squeezed and desorbed; at the same time, it can also use the vibration of the water body to flush the pores of the outer interception layer 11 from the inside to the outside, thereby effectively ensuring the connectivity between the inner bacterial layer 12 and the water body, thereby effectively ensuring the stable release of the bacterial agent and effectively ensuring the efficient repair of the water body.

[0029] The second implementation method: This embodiment is based on the first embodiment, with a micro unit display module added, and the rest of the parts remain the same as the first embodiment.

[0030] Figure 10-11It is shown that a micro-unit display module is fixedly connected to the upper end of the inner partition 201, and the micro-unit display module is connected to the control center signal. The micro-unit display module includes a pull rope 8 fixedly connected to the inner partition 201 and a liquid-measuring float 6 fixedly connected to the end of the pull rope 8. The liquid-measuring float 6 includes a hollow ball 61 of air and a pressure sensor 62 fixedly intercepted at the bottom of the hollow ball 61. The hollow ball 61 is bored with wire holes at the corresponding positions of the detection ends of the pressure sensor 62. The sinking carrier ball 5 movably passes through the wire holes and is fixedly connected to the detection end of the pressure sensor 62. When the pull rope 8 is fully extended, the bottom of the liquid-measuring float 6 is just flush with the top of the convergence tube 2. When water enters the convergence tube 2, the liquid-measuring float 6 rises under the action of the water buoyancy, causing the pull rope 8 to be gradually straightened, and then the pressure sensor 62 generates force data. When the permeability of the outer interception layer 11 is normal, the force data generated will quickly disappear when the water body vibrates, and the process is repeated continuously.

[0031] It is worth noting that in this embodiment, the bottom of the water spray pipe 43 passes through the cavity and extends to the bottom of the outer intercepting layer 11. When the water body oscillates in step S42 and the water enters the double-layer float 1, when the bottom of the double-layer float 1 is blocked and the permeability is very low, the water entering it is difficult to flush it, and because the end of the water spray pipe 43 is located in the outer intercepting layer 11, the water entering the convergence tube 2 is difficult to be quickly ejected, and the falling speed of the liquid level in the convergence tube 2 is slower than when the outer intercepting layer 11 is not blocked, so that the change speed of the data on the pressure sensor 62 is significantly slowed down. Based on this situation, the control center can judge that the outer intercepting layer 11 may be blocked. At the same time, when the enzyme activity sensor detects that the activity of the nearby bacterial agent is low, the control center judges that it is blocked, and then sends a blockage signal to the mobile terminal. When the number of blockage signals received by the mobile terminal exceeds the preset threshold, corresponding processing measures can be taken, such as adding bacterial agents.

[0032] Among them, when the data of the pressure sensor 62 is not obviously abnormal, but the enzyme activity sensor detects that the activity of the nearby bacterial agent is significantly lower, it means that most of the bacterial agent has been released, or the bacterial agent has been abnormally inactivated. The staff can also apply new bacterial agent based on this data.

[0033] In this embodiment, step S43 is: After the water body fluctuates, it is left to stand for a period of time to allow the water body to return to calm. At this time, the enzyme activity sensor at the bottom of the deep diffusion carrier is used to detect the activity of the bacteria in the water body in real time, and the micro-display unit is used to detect whether the outer layer of the floating plate of the deep diffusion carrier is blocked. According to the blockage situation and the activity of the bacteria, a comprehensive judgment is made on whether a new deep diffusion carrier should be put in to supplement the bacteria.

[0034] Under the action of the micro-display unit, it is also possible to detect whether the outer layer of the floating plate of the deep diffusion carrier is blocked. When it is blocked abnormally and the bacterial agent cannot be released normally, the staff can promptly release a new deep diffusion carrier to effectively ensure the stable progress of the water body restoration process.

[0035] It is worth noting that Figure 12 A photovoltaic panel 71 is also installed on the top of the outer interception layer 11. The photovoltaic panel 71 is electrically connected to the micro power supply. The photovoltaic panel 71 is externally mounted on a ring light strip 72. The ring light strip 72 is connected to the control center signal and is electrically connected to the micro power supply. The photovoltaic panel 71 can generate a certain amount of electricity, thereby allowing the entire micro power supply to power the electromagnetic core 13 for a longer period of time, thereby enabling the double-layer floating plate 1 to better maintain its ability to release the bacterial agent. At the same time, when the micro-display unit detects that the bottom of the double-layer floating plate 1 is clogged, the control center can control the ring light strip 72 to illuminate accordingly, allowing staff to recover the bacteria in a targeted manner. At the same time, staff can also roughly determine the abnormal rate of deep diffusion carriers in the water body based on the overall luminescence of multiple deep diffusion carriers on the water surface, facilitating the timely addition of new deep diffusion carriers, ensuring more stable and efficient water restoration, and facilitating the targeted recovery of abnormal deep diffusion carriers by staff. In addition, this part is optional and can be set according to actual needs during implementation.

[0036] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
