Description

Technical Field

[0001] The invention relates to the technical field of biological fouling prevention and control of water pipelines, and in particular to a multi-channel array ultraviolet advanced oxidation marsh clam fouling prevention and control device for water pipelines. Background Art

[0002] Limnoperna fortunei is an extremely aggressive invasive fouling organism. Biofouling caused by Limnoperna fortunei poses a great threat to major water transfer projects in my country and even around the world, and has caused serious engineering fouling and economic losses.

[0003] Marsh clams can attach to the inner wall of water pipelines at high density, blocking the pipelines, reducing water delivery efficiency, causing production stagnation and safety accidents; the metabolic activities and foot thread erosion after the attachment of marsh clams will aggravate the corrosion of the pipeline wall, affecting the structural safety of engineering facilities; the reproduction, metabolism and excretion and death of marsh clams will consume a large amount of dissolved oxygen and release organic carbon and ammonia nitrogen, causing water pollution and seriously threatening the water quality of pipeline water. The development of marsh clam biofouling prevention and control technology has become a crucial part of solving the ten major scientific problems in the Yangtze River Basin. Marsh clam biofouling prevention and control technology mainly includes source control, physical control, biological control, chemical control, and integrated control. Among them, physical control and chemical control technology are suitable for water pipeline systems: physical control technology mainly uses sedimentation tanks and adsorption tanks to separate marsh clam larvae and adult shellfish in the water body, uses turbulent flow fields to kill marsh clam larvae, and uses optical ultraviolet to destroy the genetic material of marsh clams or optically induces the expulsion of marsh clams from attachment. Chemical control technology mainly uses strong oxidizing chemicals or biotoxic agents to kill marsh clams, or uses surfactants or paints to reduce the attachment of marsh clams on the surface of hydraulic structures. Physical control methods usually do not involve the use of chemical agents, and have the advantages of being environmentally friendly, sustainable, and flexible to regulate. However, the killing field of physical control technology is weakened by the water flow field, and the killing efficiency is relatively low. Chemical control methods, with the support of powerful oxidants, have the advantages of significant control effects, quick results, and clean surfaces, but the addition of chemical agents has certain conflicts with ecological environmental protection. UV-coupled advanced oxidation technology is a more environmentally friendly, economical, and efficient remediation method.

[0004] Existing UV advanced oxidation water treatment is mainly based on low-pressure UV killing and chemical advanced oxidation field killing pathogenic microorganisms and organic matter in water. However, in heavy-load water supply projects, there is a characteristic of high single-pipe flow rate. The UV killing dose required for plankton represented by larvae of swamp clams is dozens of times that of common bacteria. Existing UV advanced oxidation water treatment technology is difficult to handle high-speed water flow conditions; advanced oxidation technology is mainly effective in treating viruses, bacteria and organic pollution in water bodies. Swamp clams can control the double shell to isolate the chemical killing field and tissue, so the efficiency of advanced oxidation is relatively low.

[0005] Therefore, there is an urgent need for a comprehensive, efficient, non-stop maintenance, and environmentally friendly pressurized water prevention and control system that can prevent the fouling of larvae and adult shellfish in water pipelines. Summary of the invention

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following describes a water pipeline multi-channel array ultraviolet advanced oxidation clam fouling prevention and control device according to an embodiment of the present invention with reference to the accompanying drawings.

[0028] Figure 1 A block diagram of a water pipeline multi-channel array ultraviolet advanced oxidation clam fouling prevention and control device provided in an embodiment of the present invention.

[0029] like Figure 1 As shown, the water pipeline multi-channel array ultraviolet advanced oxidation clam fouling prevention and control device includes: a front dual-channel basket filter 101, an array ultraviolet water distribution pipe 102, an oxidant auxiliary cleaning module 103, an array ultraviolet killing pipe 104, a numerical control system 105 and an ultraviolet water exchange pipe 106.

[0030] Among them, the front dual-channel basket filter 101 adopts a unique dual-channel design, including a single channel and a spare channel, which is used to filter the adult clams in the target risk pipeline through the single channel, and switch to the spare channel when it is blocked to the limit value. The array ultraviolet water distribution pipe 102 is placed vertically relative to the target risk pipeline flow, and is used to adjust the activation and flow of the branch pipe according to engineering requirements or water conditions to evenly distribute the water flow. The oxidant auxiliary cleaning module 103 is arranged between the front dual-channel basket filter and the array ultraviolet water distribution pipe, and is used to place environmentally friendly agents between the front dual-channel basket filter and the ultraviolet water distribution pipe. The array ultraviolet killing pipe 104 is connected to the array ultraviolet water distribution pipe 102 to form a dense ultraviolet killing area to kill the larvae and adult clams of the marsh clam, and to generate free radicals through ultraviolet activation of the environmentally friendly agent to remove the attached marsh clam larvae and marsh clam foot silk protein in the pipe. The numerical control system 105 is used to control the flow rate of the array UV water distribution pipe 102, the start and stop of the array UV killing pipe 104 and the amount of the oxidant auxiliary cleaning module 103 according to the engineering conditions. The UV water outlet pipe 106 is connected to the array UV killing pipe 104 to collect the water treated by the array UV killing pipe 104.

[0031] Specifically, the front dual-channel basket filter 101 ensures that the pipeline is unobstructed through the single-channel operation and spare channel switching mechanism. When blockage is detected, it can be repaired without stopping the machine, automatically switch channels and facilitate the cleaning of large-sized swamp clams. The array ultraviolet water distribution pipe 102 with adjustable diversion is placed vertically, and the activation and flow of the diversion pipe are flexibly adjusted according to the water conditions to achieve balanced distribution of water flow to the array ultraviolet killing pipe, ensuring the consistency of the treatment effect. The oxidant auxiliary cleaning module 103 is provided with an oxidant delivery port between the front dual-channel basket filter 101 and the array ultraviolet water distribution pipe 102, and an environmentally friendly agent (ozone O3 or hydrogen peroxide H2O2) is delivered. After the medium-pressure ultraviolet activation of the array ultraviolet killing pipe 104, it continuously activates and produces strong oxidizing hydroxyl free radicals, effectively removing organic impurities attached to the quartz glass wall and the inner wall of the pipeline, especially the swamp clam foot silk protein, maintaining the effective operation of the device, and extending the life of the quartz tube and the maintenance cycle. The high-efficiency ultraviolet killing tube array 104 is provided with a plurality of ultraviolet killing tubes, each of which is equipped with a high-transmittance ultraviolet quartz glass tube, and a long-acting medium-pressure ultraviolet lamp is installed in the high-transmittance ultraviolet quartz glass tube to form a dense ultraviolet killing area. This design allows the ultraviolet lamp and the visual system status to be inspected without stopping the machine, which improves the convenience of maintenance. The numerical control system 105 accurately controls the array ultraviolet water distribution pipe 102 to regulate the flow rate in the array ultraviolet water distribution pipe 102. The calculation device is preset to calculate the number of arrays required to be enabled under different working conditions and the flow control, especially to ensure that all sizes of clams (including larvae to adult shellfish) can achieve the killing effect and completely prevent the contamination of clams. The array ultraviolet killing tube 105 is connected to the opposite ultraviolet external water pipe 106 to ensure that the treated water flow meets the engineering requirements, guarantees the design flow, and guarantees the quality and stability of the water supply.

[0032] In some embodiments, two groups of pre-dual-channel basket filters 101 are generally selected, each of which is provided with a filter screen with a size of 5 mm. The size screening principle of the pre-basket filter is used to physically separate large-sized clams and pipeline flow.

[0033] In some embodiments, the array ultraviolet water distribution pipe 102 decomposes the high-speed and high-flow main flow into multiple sections of low-flow and low-speed diversion, prolonging the stagnation time of the pipeline water flow in the killing field, thereby prolonging the killing dose received by the flowing clams in the killing field, especially controlling the flow rate of each killing pipe to be the same, so as to uniformly adjust the ultraviolet lamp activation parameters in the high-efficiency ultraviolet killing pipe array 104. Among them, the high-speed and high-flow main flow refers to a flow rate greater than 1m / s, a load pressure greater than 0.4MPa, and an ultraviolet lamp activation parameter of 200W.

[0034] In some embodiments, the array ultraviolet killing tube 104 is horizontally placed in a hollow quartz tube, and a medium-pressure ultraviolet lamp is placed in the hollow quartz tube. The hollow quartz tube can effectively isolate the pipeline and the ultraviolet lamp, so that maintenance can be carried out without stopping. The quartz tube uses a low ultraviolet absorption tube to improve the light transmission efficiency. The medium-pressure ultraviolet is selected because the medium water absorbs the low-pressure ultraviolet better than the medium pressure, and the high-pressure ultraviolet cannot effectively kill aquatic organisms. In the array ultraviolet killing tube 104, the clams die under two effects: one is that the core molecular structure DNA and RNA of the clams are destroyed under ultraviolet light, resulting in the weakening of the vitality of the clams and further death. The environmentally friendly agents added by the oxidant auxiliary cleaning module 103 include gaseous oxidants (such as O3) and liquid oxidants (H2O2), which are activated to generate highly oxidizing free radicals under the action of the ultraviolet field. The free radicals destroy the external structure and internal genetic components of the clams and disintegrate the life of the clams from the molecular structure. When the incoming flow contains more byssin, the molecular structure of byssin is very easy to combine with the quartz surface, which will lead to the failure of the optical performance of the quartz tube. Through the oxidant auxiliary cleaning module 103, the hydroxyl radicals activated by the ultraviolet light field are additionally involved in the decomposition of the main fouling protein byssin of the swamp clam: the byssin and the inner wall of the pipe are mainly bonded through the Mfp protein at the bottom of the byssin protein group. The dopa group of the Mfp protein reacts preferentially under the action of the hydroxyl radical. As the dopa group is destroyed, the byssin structure is disintegrated in the ultraviolet advanced oxidation field. Through the ultraviolet advanced oxidation field, the fouling of the swamp clam in the optical blind area is controlled, and the organic impurities in the incoming flow, especially the byssin, are cleaned, which can effectively extend the service life of the system and the maintenance cycle of the quartz tube.

[0035] The working process of the water pipeline multi-channel array ultraviolet advanced oxidation clam fouling prevention and control device proposed in the embodiment of the present invention is as follows:

[0036] Step 1, according to the size, flow requirements and pressure level of the target water pipeline, select the appropriate steel model (such as stainless steel) to make filters, pipes and support structures. Perform spatial measurements on site and plan the layout of the front dual-channel basket filter 101, array UV water distribution pipe 102, UV killing tube array 104 and numerical control system 105 to ensure sufficient operating space and easy maintenance. Install two independent filter channels (i.e., the front dual-channel basket filter 101) in the target water pipeline, and each channel is equipped with a basket filter to capture and remove large-sized impurities in the water, such as clams and clams. When the dual channels flow, ensure that the two channels can be switched automatically or manually to achieve the function of one use and one standby.

[0037] At the same time, an array of ultraviolet water distribution pipes 102 and an array of high-efficiency ultraviolet killing tubes 104 are arranged, and a numerical control system 105 and an environmentally friendly oxidant auxiliary cleaning module 103 are integrated. Specifically, the main pipe of the front dual-channel basket filter 101 is connected to the incoming flow pipeline, and the auxiliary pipe is connected in parallel to the main pipe wall. According to the water flow rate and pipe diameter as well as the ultraviolet radiation requirements, the matching array of ultraviolet water distribution pipes 102 are installed, and the high-efficiency ultraviolet killing tube array 104 is evenly arranged on the array of ultraviolet water distribution pipes 102. Ensure that each ultraviolet killing tube can evenly receive water flow to achieve effective killing. The numerical control system 105 including PLC, sensors, actuators, etc. are integrated into the system to realize intelligent control of the front dual-channel basket filter 101, the ultraviolet killing tube array 104, the oxidant delivery and other equipment. An oxidant dispersing and feeding unit (ie, oxidant auxiliary cleaning module 103) is installed in the connecting pipe between the front dual-channel basket filter 101 and the array UV water distribution pipe 102 to ensure that the oxidant can be evenly dispersed in the water flow.

[0038] Step 2: Start the pre-dual-channel basket filter 101 for initialization. Through real-time monitoring and intelligent switching mechanism, ensure the normal switching and rotation of the main channel and the backup channel to cope with the regular maintenance of the pre-dual-channel basket filter 101 without stopping. The pre-dual-channel basket filter 101 has a built-in filter. The pre-dual-channel basket filter 101 is started by the numerical control system. Regularly check whether the filter is installed correctly and whether the pre-dual-channel basket filter 101 is leaking. Check and clean the large-sized clams in the pre-dual-channel basket filter 101 to keep the pipeline unobstructed. Install and debug the water quality monitoring sensor to monitor the turbidity and medium-pressure ultraviolet absorption coefficient in real time. Set the automatic switching of the main and backup channels according to the preset switching pressure difference and the maintenance time or logic unit. Ensure that when one channel needs maintenance, the other channel can take over the work seamlessly. Clean the large-sized impurities in the pre-dual-channel basket filter 101 during maintenance and reset the main and auxiliary pipelines.

[0039] Step three, according to the water conditions and project requirements, a flow sensor can be installed in the array ultraviolet water distribution pipe 102 to monitor the water flow and the flow of each water distribution branch in real time, and the numerical control system 105 can be used to adjust the number of activated array ultraviolet water distribution pipes 102 and the flow valve to ensure that each ultraviolet killing tube can obtain the flow required for the preset working conditions.

[0040] Step 4, each group of killing tubes in the ultraviolet killing tube array 104 is built-in with multiple high-transmittance quartz glass hollow tubes and long-acting medium-pressure ultraviolet lamps according to the engineering plan, providing a material basis for forming a strong ultraviolet light killing field. The ultraviolet killing tube array 104 produces a strong ultraviolet killing light field when working, and the DNA and RNA structures of the planktonic swamp clam larvae and the small-sized adult shellfish or other aquatic organisms that are not separated by the front dual-channel basket filter 101 are destroyed after being irradiated by ultraviolet radiation, and the killing effect is achieved when the dose is reached. The design of the ultraviolet killing tube array 104 is convenient for maintenance and overhaul, allowing the replacement and maintenance of the ultraviolet lamp to be carried out without interrupting the water supply and killing, ensuring that the system continues to operate efficiently.

[0041] Step 5: Input parameters such as flow rate, water quality, source mode of clam pollution, full-size density of clam and ultraviolet killing constant to the numerical control system 105. The numerical control system 105 automatically adjusts parameters such as flow control, ultraviolet lamp activation and oxidant dosage according to the built-in example library and real-time monitoring data to ensure that the device maintains efficient operation and maintenance warning. When the ultraviolet lamp in the array ultraviolet killing tube 104 fails to operate properly, the numerical control system 105 adjusts the ultraviolet killing tube array 104 to close the bad passage and open the branch pipe with bypass redundant design. The operation and maintenance personnel can repair the ultraviolet killing tube array 104 without stopping the machine. Intelligent management ensures that the clams in the whole life cycle are completely killed and prevents the occurrence of clam biofouling downstream.

[0042] Step 6, a dispersing feeding unit (i.e., oxidant auxiliary cleaning module 103) capable of dispensing an environmentally friendly oxidant is provided between the pre-positioned dual-channel basket filter 101 and the array ultraviolet water distribution pipe 102, the oxidant is fully mixed with the water flow after dispensing, and is evenly distributed with the array ultraviolet water distribution pipe 102, and is activated under the action of the medium-pressure ultraviolet lamp of the array ultraviolet killing pipe 104 when flowing through the ultraviolet killing section, and produces strong oxidizing free radicals. The free radical represented by the hydroxyl radical has extremely high reactivity, and can react rapidly with the organic impurities attached to the quartz glass wall and the inner wall of the pipeline, and decompose it into harmless small molecules. The organic impurities attached to the quartz glass wall and the inner wall of the pipeline are removed, especially the foot silk protein of the marsh clam, and the stubborn stains such as the foot silk protein of the marsh clam can also be effectively destroyed, so that it falls off from the surface. This step is used to maintain the system clean, prolong the service life of the equipment, and kill the marsh clams that are overgrown in the ultraviolet dead corner.

[0043] Step seven, continuously monitor the optical parameters, flow rate and system operation status of the incoming water, and regularly check the operation status of the ultraviolet lamp of the array ultraviolet killing tube 104, the front dual-channel basket filter 101 and the oxidant auxiliary cleaning module 103. When the front dual-channel basket filter 101 reaches the preset limit, switch to the spare filter channel, replace the main maintenance and replace the main filter channel and filter; when the ultraviolet lamp in the array ultraviolet water distribution pipe 102 is not operating properly, adjust the array ultraviolet killing tube 104 through the numerical control system 105 to close the bad channel and open the bypass, and then repair the array ultraviolet killing tube 104 without stopping the machine. When the optical parameters and flow parameters of the incoming flow change, adjust the device parameters according to the monitoring results to ensure the long-term stable operation of the system.

[0044] The water pipeline multi-channel array ultraviolet advanced oxidation clam fouling prevention and control device proposed in the embodiment of the present invention is further explained below through a specific experimental example.

[0045] Golden mussels are a typical type of marsh clam that fouls my country's hydraulic structures. Usually, the D-type marsh clam larvae with a body length of 150μm are typical in the fouling unit water. The D-type can develop into an attachment unit within a few days, and grow to 150mm in the following year, gradually reaching sexual maturity and releasing the next generation of fouling larvae. In order to investigate the prevention and control effect of the multi-channel array ultraviolet advanced oxidation marsh clam fouling prevention and control system for water pipelines, a case study was carried out with the D-type larvae as the research target.

[0046] In the embodiment, two sets of basket filters are designed and installed for the conditions of the incoming flow pipe model being DN250 and the flow rate being 2.3m / s. The basket filters are placed horizontally. The array UV water distribution pipe is placed vertically with a height of 2m and a pipe model of DN250, which ensures the smooth flow of water and the uniform distribution of UV radiation. There are 7 array UV killing pipes arranged from top to bottom, each with a spacing of 10cm and a length of 2.5m. A convenient maintenance UV killing lamp is placed every 0.5m from the water distributor of each array UV killing pipe, which is convenient for daily maintenance and replacement. Figure 2 As shown. The oxidant injection port of the advanced oxidation cleaning module is set as a spherical nano-dispersing disk, which is located downstream of the basket filter and upstream of the water distribution pipe. A 10% dilute hydrogen peroxide solution is uniformly injected into the device through the spherical nano-dispersing disk.

[0047] In order to verify the actual effect of the device, this embodiment conducted a low-load killing effect test. The fouling scenario of releasing 1000 150 μm D-type larvae into the incoming flow at one time was simulated to evaluate the system's ability to kill aquatic organisms. Figure 3 As shown in the figure, when the array UV killing pipeline is at an optical power of 200W / group and only three pipelines are enabled, all larvae receive more than 200mJ / cm 2The simulation results show that the larvae of the incoming clam survive when the water comes from the left side, and after passing through the killing field, they gather in the water collection pipe, and all the larvae of the clam in the water collection pipe die. This embodiment verifies the efficient killing effect of the system.

[0048] In summary, the multi-channel array ultraviolet advanced oxidation clam fouling prevention and control device for water pipelines proposed in the embodiment of the present invention has the following beneficial effects:

[0049] (1) The device removes large-sized clams through physical filtration, removes small-sized clams through ultraviolet light killing, and kills clams in optical blind spots through ultraviolet advanced oxidation, ensuring the long-term safety of the downstream of the water pipeline and achieving comprehensive and efficient prevention and control.

[0050] (2) The device uses environmentally friendly oxidants that can self-quench and decompose ozone (O3) and hydrogen peroxide (H2O2) that are harmless to the environment, and produce strong oxidizing free radicals under the activation of medium-pressure ultraviolet lamps.

[0051] (3) The built-in numerical control system can automatically adjust the system flow, UV light activation and oxidant dosage according to the input parameters such as flow, water quality and clam density, thus realizing intelligent management. This not only improves the operating efficiency of the system, but also ensures the effective killing of clams throughout their life cycle, preventing biofouling in the downstream.

[0052] (4) Advanced oxidation technology is used to remove organic impurities attached to the inner wall of the pipeline, especially foot silk protein, effectively maintaining the cleanliness of the system, extending the service life and maintenance cycle of key components such as quartz tubes, and reducing maintenance costs.

[0053] (5) The device is suitable for water pipelines with high load and high flow conditions, and can deal with the problem of clam fouling under various working conditions. By adjusting the number of UV water distribution pipes activated and the flow distribution, it can ensure that the incoming flow is evenly distributed to each UV killing pipe, ensuring the consistency of the killing effect.

[0054] (6) The device is equipped with real-time monitoring and intelligent switching mechanisms, which can be inspected and maintained without stopping the system, ensuring the system's continuous water supply capacity and long-term stable operation. At the same time, by optimizing the system layout and configuration, the risk of water outages caused by equipment failures is reduced.

[0055] Next, a method for preventing and controlling fouling of a water pipeline using a multi-channel array of ultraviolet advanced oxidation clams according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0056] Specifically, Figure 4 A schematic flow chart of a method for preventing and controlling fouling of water pipelines using a multi-channel array ultraviolet advanced oxidation method provided in an embodiment of the present invention.

[0057] like Figure 4As shown, the water pipeline multi-channel array ultraviolet advanced oxidation clam fouling prevention method comprises the following steps:

[0058] In step S401, a pre-installed dual-channel basket filter is designed and installed according to the target risk pipeline and the target site space.

[0059] In step S402, the front dual-channel basket filter is sequentially connected to an array of ultraviolet water distribution pipes and an array of high-efficiency ultraviolet killing pipes, and a numerical control system and an environmentally friendly oxidant auxiliary cleaning module are integrated.

[0060] In step S403, the front dual-channel basket filter is started to check and clean the adult clams in the target risk pipeline through the single-channel and spare-channel switching mechanism.

[0061] In step S404, according to the incoming water conditions and target requirements, the numerical control system is used to adjust the number of activated array UV water distribution pipes and the flow distribution to evenly distribute the incoming flow to each UV killing tube.

[0062] In step S405, an environmentally friendly agent is added between the front dual-channel basket filter and the ultraviolet water distribution pipe through the oxidant auxiliary cleaning module, and the amount of the environmentally friendly agent added is adjusted through the numerical control system.

[0063] In step S406, an array of ultraviolet killing tubes is used to form a dense ultraviolet killing area to kill the larvae and adult clams, and ultraviolet-activated environmentally friendly agents are used to generate free radicals to kill the larvae and foot silk proteins of the clams flowing in the ultraviolet killing section.

[0064] It should be noted that the above explanation of the embodiment of the multi-channel array ultraviolet advanced oxidation clam fouling prevention and control device for water supply pipelines is also applicable to the multi-channel array ultraviolet advanced oxidation clam fouling prevention and control method for water supply pipelines of this embodiment, and will not be repeated here.

[0065] The method for preventing and controlling fouling of water pipelines by ultraviolet advanced oxidation using a multi-channel array according to an embodiment of the present invention has the following beneficial effects:

[0066] (1) Remove large-sized clams through physical filtration, remove small-sized clams through ultraviolet light killing, and kill clams in optical blind spots through ultraviolet advanced oxidation, ensuring the long-term safety of the downstream of the water pipeline and achieving comprehensive and efficient prevention and control.

[0067] (2) Environmentally friendly oxidants are used, which can self-quench and decompose ozone (O3) and hydrogen peroxide (H2O2) that are harmless to the environment, and produce strong oxidizing free radicals under the activation of medium-pressure ultraviolet lamps.

This not only improves the operating efficiency of the system, but also ensures the effective killing of clams throughout their life cycle, preventing biofouling in the downstream.

[0069] (4) Advanced oxidation technology is used to remove organic impurities attached to the inner wall of the pipeline, especially foot silk protein, effectively maintaining the cleanliness of the system, extending the service life and maintenance cycle of key components such as quartz tubes, and reducing maintenance costs.

[0070] (5) It is suitable for water pipelines with high load and high flow conditions, and can deal with the problem of clam contamination under various working conditions. By adjusting the number of UV water distribution pipes activated and the flow distribution, it can ensure that the incoming flow is evenly distributed to each UV killing pipe, ensuring the consistency of the killing effect.

[0071] (6) It has a real-time monitoring and intelligent switching mechanism, which enables inspection and maintenance without stopping the system, ensuring the system's continuous water supply capacity and long-term stable operation.
