Description

Technical Field

[0001] The invention relates to the technical field of water supply, and in particular to an integrated device for coupling in-situ repair of reservoir water bodies with membrane filtration water purification. Background Art

[0002] In recent years, rural decentralized water supply has received more and more attention. In most rural areas, traditional drinking water treatment processes are used, including coagulation, sedimentation, filtration and disinfection. However, the traditional construction of centralized drinking water treatment plants has inevitable disadvantages such as large land occupation, high investment in building facilities, complex operation and maintenance, and high consumption of energy and chemicals. Due to the complex geographical conditions, scattered residences and relatively limited economic levels in rural areas, traditional water purification technologies and devices have various "water and soil incompatibility" problems in rural water supply, making it difficult to promote and apply. Reservoir water and lake water are important drinking water sources for rural decentralized water supply, and their water quality safety is very important. However, due to endogenous and exogenous pollution, the water quality of reservoirs is low in the bottom water body, and there are often problems such as eutrophication, organic pollution, algae outbreaks, and seasonal iron and manganese pollution. These problems not only affect the ecological balance of reservoir water bodies, but also directly threaten the water quality safety of rural water supply systems.

[0003] In response to the above water pollution problems, domestic and foreign experts have conducted a lot of research. Foreign countries usually use isothermal oxygenation and artificial forced mixing technology. Among them, isothermal oxygenation technology is mainly used to solve the problem of endogenous pollution release in sediments caused by hypoxia at the bottom of deep-water reservoirs, but it cannot effectively deal with algae outbreaks; while artificial forced mixing technology can control algae growth and eutrophication by destroying the thermal stratification of water bodies, but its disadvantage is high energy consumption. The pumping aeration water quality improvement technology optimizes and combines these two methods, and has multiple advantages such as eliminating stratification, inhibiting algal blooms, and enhancing the activity of functional microorganisms, thereby effectively controlling the eutrophication of water bodies caused by exogenous and endogenous pollution. Unlike complete mixing that is difficult to achieve under natural conditions, the pumping aeration system can artificially promote full mixing of water bodies and set the completion time according to actual needs. However, pumping aeration is not effective in removing iron and manganese pollution.

[0004] Membrane separation technology is known as the third generation of drinking water treatment technology. It can effectively remove suspended matter, colloids and pathogenic microorganisms in water. It has the advantages of small footprint, high interception rate, stable effluent quality and easy automated management and operation. It has been widely used in water treatment. At present, the most widely used membrane separation technology is ultrafiltration membrane water purification technology. However, the working pressure of ultrafiltration processes at home and abroad is mostly 50-200kpa. The high-pressure operating environment greatly increases the cost of ultrafiltration water purification and aggravates membrane pollution. Frequent physical and chemical cleaning is required to control membrane pollution and ensure water production. A large number of auxiliary equipment is also required, which increases costs and operating and maintenance workload. At present, ultrafiltration devices use chemical cleaning to control microbial contamination, consume a large amount of chemical agents, and discharge a large amount of chemical wastewater. In addition, the ultrafiltration process has a poor effect on the removal of soluble substances such as organic matter and ammonia nitrogen in water. The removal rate of DOC in water is usually less than 15%, and the removal rate of ammonia nitrogen is less than 10%. Even if certain strengthening measures are taken (such as combined with powdered activated carbon process or online coagulation process), the removal effect of organic matter and ammonia nitrogen is still not obvious, and the operating cost and maintenance workload are significantly increased. And because the ultrafiltration membrane retains pollutants based on the membrane pore size to play a selective permeability, and Fe 2+ and Mn 2+ The size is much smaller than the pore size of the ultrafiltration membrane, so it cannot be effectively removed.

[0005] Gravity driven membrane system (GDM) is a process that uses gravity pressure difference as the driving force of the membrane. During the long-term filtration process, a biological filter cake layer will gradually form on the membrane surface, so that the GDM process can treat pollutants in the raw water through the biochemical action of the filter cake layer and the double-layer interception action of the filter cake layer and the ultrafiltration membrane, significantly enhancing the removal performance of pollutants and giving the GDM process excellent pre-filtration ability. Unlike traditional ultrafiltration, the GDM process adopts a continuous filtration mode, that is, no hydraulic backwashing and chemical cleaning are used to control membrane fouling during the long-term operation of GDM. In actual application, users only need to open or close the outlet valve to control the operation of GDM and obtain the required drinking water, so the operation is extremely simple. The GDM process adopts a non-cleaning filtration mode, so compared with the traditional ultrafiltration process, it does not need to be equipped with a hydraulic backwashing system, a cross-flow system (such as a cross-flow pipeline and control system), a chemical cleaning system, etc., and also saves the maintenance of the above systems, so the maintenance workload of GDM during long-term operation is very small. The filtration head used by GDM is 0.002-0.007MPa, which is much lower than the traditional ultrafiltration process, significantly reducing the energy consumption of the process operation. The formation of the GDM biological cake layer can effectively promote the removal of viruses, trace organic matter (sulfamethoxazole, SMZ), ammonia and low molecular weight organic matter (assimilable organic carbon, AOC), and can also effectively remove pollutants such as iron, manganese and ammonia nitrogen in the water. Therefore, the GDM process can effectively overcome the problems faced by the current ultrafiltration-based membrane filtration water purification technology and the drawbacks of conventional processes, and has a strong adaptability to changes in raw water quality. It is a low-cost, low-maintenance water treatment technology. It can be perfectly applied to decentralized water supply and ensure the safety of water for residents in decentralized water supply areas such as mountainous areas.

[0006] To sum up, there is an urgent need for an integrated device that couples in-situ restoration of reservoir water bodies with membrane filtration water purification, which can simultaneously realize water source restoration and water quality purification. There is no need to build a water plant or add chemicals, and water purification can be achieved without a plant, chemicals or consumption. It can significantly reduce water production costs and help solve the difficulties faced by decentralized water supply in rural areas. It has urgent market needs and important social significance.

[0019] Compared with the prior art, the present invention has achieved the following beneficial technical effects:

[0020] 1. The present invention provides an integrated device for coupling in-situ repair of reservoir water bodies with membrane filtration water purification. It does not rely on the construction of large-scale water plants, but directly improves and purifies water quality at the water source, thereby reducing the overall cost of the water supply system. The water source water is repaired in situ by pumping aeration, and the GDM membrane component biological filter cake layer and ultrafiltration membrane have a dual purification effect on the water source.

[0021] 2. The present invention provides an integrated device for coupling in-situ restoration of reservoir water bodies with membrane filtration water purification. A guide tube is set in the design. The straight tube structure of the diversion area below the water surface increases the water inlet flux of the GDM component by reducing the water flow cross-sectional area, promotes the shedding and renewal of the biological filter cake layer, alleviates membrane pollution, but at the same time avoids its complete shedding due to water flow impact, and achieves a double interception effect; the water collection area on the water surface of the guide tube is funnel-shaped, and the water is sprayed into the air through the water-lifting aeration device and flows down along the funnel wall of the guide tube, so that the water flow is oxygenated and aerated again during the process of lifting and hanging on the wall.

A water pumping and aeration device is installed on the water surface in the guide tube, and the bottom water outside the guide tube is pumped and sprinkled into the guide tube. This process makes the water in the guide tube flow vertically downward, thereby increasing the dissolved oxygen content of the bottom water body and forming a continuous circulation oxygenation in the anoxic area of ​​the isothermal layer.

[0023] 4. The present invention provides an integrated device for coupling in-situ restoration of reservoir water bodies with membrane filtration water purification. A solar floating panel is installed. The solar cells supply power to the integrated device, saving electricity consumption. At the same time, the solar panels and the bottom foam layer jointly provide buoyancy to ensure that the device floats stably on the water surface.

[0024] 5. The present invention provides an integrated device for coupling in-situ restoration of reservoir water bodies with membrane filtration water purification. Based on the good renewal and oxygenation of source water by pumping and aeration, electrolytic aeration is also arranged at the bottom of the membrane module to supplement oxygen while promoting biological action and decomposition of organic matter.

[0025] 6. The present invention provides an integrated device for coupling in-situ restoration of reservoir water bodies with membrane filtration water purification. A forced aeration system is added to the bottom of the membrane module. As a backup or auxiliary means, when the dissolved oxygen online monitoring system detects that pumping aeration and electrolytic aeration cannot meet the system's high dissolved oxygen requirements, the system is quickly started and effectively replenishes dissolved oxygen, thereby ensuring the optimization of the membrane module operating environment and improving the overall processing efficiency and stability.

[0026] 7. The present invention provides an integrated device for coupling in-situ restoration of reservoir water bodies with membrane filtration water purification. A slide rail is arranged in the guide tube and connected to the membrane assembly, allowing the membrane assembly to slide freely up and down on the slide rail. A buoy is used to control the height difference with the liquid surface, and the membrane assembly floats up and down with the water level. The device is suitable for both dry and flood seasons.

[0033] Embodiment 1:

[0034] This embodiment provides an integrated device for coupling in-situ remediation of reservoir water bodies with membrane filtration water purification, such as Figure 1 As shown, it includes a guide tube assembly, which includes an upper water collection area 28 and a lower guide area 26 of the guide tube. The lower guide area 26 of the guide tube is set in the water body of the reservoir through a supporting assembly. The upper and lower guide areas 26 of the guide tube are floatably provided with GDM membrane pools 27, and a GDM membrane assembly 11 is arranged in the GDM membrane pool 27. The lower part of the GDM membrane pool 27 is connected with the water inlet assembly, and the upper part of the GDM membrane pool 27 is connected with the water outlet assembly. A forced aeration assembly and an electrolytic aeration assembly 10 are arranged below the GDM membrane assembly 11, and a water-lifting aeration assembly is arranged above the GDM membrane pool 27.

[0035] As an implementation method, the upper water collection area 28 of the guide tube is a funnel-shaped structure and is set 1m above the water surface. The lower diversion area 26 of the guide tube is a straight tube structure with the bottom greater than 3-4m from the bottom of the reservoir to prevent the pumping water flow from stirring up the mud at the bottom of the pool.

[0036] As an implementation mode, the support assembly includes an anchor pier 1, and the upper surface of the anchor pier 1 is fixedly connected to the bottom of the guide area 26 at the lower part of the guide tube through the bracket 2, so as to achieve stable support.

[0037] As an implementation method, an anti-fall layer 23 is provided on the top of the upper water collection area 28 of the guide tube to prevent external debris such as fallen leaves, branches, floating garbage, etc. from falling into the guide tube assembly, thereby keeping the water inside the guide tube assembly clean and reducing subsequent maintenance; a fish intercepting net 3 is provided at the bottom of the lower diversion area 26 of the guide tube, and the mesh size is moderate to intercept large fish and aquatic organisms to prevent them from accidentally entering the guide tube assembly, affecting the water treatment effect or causing equipment damage.

[0038] As an implementation mode, a sliding track 21 is provided on the side of the guide tube lower guide area 26, and the GDM membrane pool 27 can be slidably arranged on the sliding track 21. The top of the GDM membrane pool 27 is connected with a buoy 20; the GDM membrane assembly 11 is a fascia membrane assembly, which is 2m long and the top is 0.6-2m above the water surface. The GDM membrane pool 27 is 10-100cm away from the inner wall of the guide tube lower guide area 26. Through the sliding connection between the GDM membrane pool 27 and the inner wall of the guide tube lower guide area 26 and the connection between the top and the buoy 20, the buoy 20 is used to control the height difference with the liquid surface. The GDM membrane pool 27 can automatically rise and fall with the height of the water surface and always remain below the liquid surface. It is suitable for dry season and flood season.

[0039] As an implementation mode, the water inlet assembly includes a water inlet pipe, and a first check valve 4 and a water inlet valve 5 are provided on the water inlet pipe to achieve water inlet.

[0040] As an implementation mode, the water outlet component includes a water outlet pipe and an exhaust pipe. The water outlet pipe is provided with a liquid flow meter 12, a pressure gauge 14, a water outlet valve 13 and a dissolved oxygen online monitoring component 22; the exhaust pipe is provided with an exhaust component 15 and an exhaust valve 16, thereby realizing water outlet and exhaust.

[0041] As an implementation mode, the forced aeration component includes an air pump 6, which is connected to the bottom forced aeration plate 9 through an aeration pipe. The aeration pipe is provided with an air valve 8 and an air flow meter 7. The bottom forced aeration plate 9 is automatically started according to the dissolved oxygen content. The bottom forced aeration plate 9 is located 20-50 cm from the bottom of the GDM membrane assembly 11. Dual air path aeration is adopted. Microbubble intermittent aeration is responsible for oxygenation. It is started when the dissolved oxygen is less than 3 mg / L; large bubble aeration is used to regularly clean the membrane surface to prevent deposition membrane pollution.

[0042] As an implementation mode, the water-lifting aeration component includes a water-lifting aerator 19, a foam layer floating plate 29 is provided below the water-lifting aerator 19, a second check valve 17 and a water-lifting valve 18 are provided at the inlet of the water-lifting aerator 19, and the outlet of the water-lifting aerator 19 is inclined upward. When the outlet water online detection system detects that the dissolved oxygen content is reduced, the bottom water outside the guide tube component is extracted and sprinkled into the guide tube component, and flows down along the funnel wall of the upper water collection area 28 of the guide tube. The water flow is oxygenated and aerated again during the sprinkling and wall flow. The water-lifting aeration destroys the thermal stratification of the water body by lifting water, so that the water flow in the guide tube flows vertically downward, drives the bottom water body to mix with the upper water body, increases the dissolved oxygen concentration of the bottom water body, and forms a continuous cycle of oxygenation in the anoxic zone of the isothermal layer.

[0043] As an implementation method, an electrolytic aeration assembly 10 is installed below a GDM membrane assembly 11. The electrodes around the GDM membrane assembly 11 are cathodes, and an inert material, platinum, is used to generate hydrogen by electrolysis. The middle electrode is an anode, and an inert material, platinum, is used to generate oxygen by electrolysis. Electrolytic aeration provides oxygen to the GDM membrane assembly 11 while promoting biological action and decomposition of organic matter.

[0044] As an embodiment, it also includes a solar power supply component, which includes a solar float 24. A foam layer 25 is provided at the bottom of the solar float 24, which is connected to the buoy 20. It not only provides power for water-lifting aeration, electrolytic aeration and forced aeration, but also provides buoyancy to ensure that the device floats stably on the water surface. The electrolytic aeration component 10 includes a cathode and an anode, and the electrolytic aeration component 10 is connected to the solar float 24.

[0045] The present invention provides an integrated device for coupling in-situ restoration of reservoir water bodies with membrane filtration water purification, and its working principle is as follows: when the dissolved oxygen online monitoring component 22 detects that the dissolved oxygen content is reduced, the water-lifting aerator 19 is first started. The device is powered by a solar floating plate 24, extracts the bottom water outside the guide tube component, sprays it into the guide tube component, and flows down through the upper funnel structure, driving the guide tube water flow to flow vertically downward, thereby breaking the thermal stratification of the water body, promoting the mixing of the upper water body and the bottom water body, thereby increasing the dissolved oxygen concentration of the bottom water body, and forming a continuous circulation oxygenation in the isothermal layer anoxic zone. The raw water flows into the GDM membrane pool 27 under the action of gravity. After the biological action of the biological filter cake layer and the dual purification of the ultrafiltration membrane, the effluent is directly disinfected by chlorination, and does not need to be pumped, relying entirely on gravity. At the same time as the water-lifting aeration, electrolytic aeration powered by the solar floating plate 24 is used. The anode in the middle of the membrane produces oxygen to supply oxygen to the GDM membrane component, while promoting the decomposition of organic matter by biological action. When the effects of pumping aeration and electrolytic aeration are detected to be insufficient, the system will automatically start the forced aeration function. The bottom forced aeration plate 9 adopts a dual air path design, in which the small bubble aeration system is responsible for intermittent oxygenation, and the automatic start condition is that the dissolved oxygen content is lower than the preset value of 3mg / L; while the large bubble aeration system is started regularly, and the membrane surface is cleaned by the water flow flushing effect generated by the large bubbles to prevent pollution.

[0046] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
