Description

Technical Field

[0001] The present invention relates to the technical field related to water resource recovery, and particularly to a medium water resource ecological recovery filtering device and system. Background Art

[0002] A water resource recovery system is a combination of facilities and technologies for collecting, treating, and reusing water resources, aiming to achieve the recycling of water resources and improve the utilization efficiency of water resources. The recovery of water resources includes, but is not limited to, rainwater, building wastewater, occasionally discharged swimming pool drainage, etc. After a complete water resource recovery system is constructed, it can also be used for teaching purposes. That is, on the basis of ensuring the normal operation of the medium water treatment equipment and facilities and the stable compliance of the effluent, teaching effects can be achieved by adding data display screens, process unit display signs, panoramic sand tables of the process flow, etc. Moreover, the medium water system is equipped with an intelligent operation and maintenance system to maximize the automation and intelligent level of the medium water treatment system, reduce operation and maintenance costs, and at the same time, through appropriate landscape design, make the medium water treatment station, artificial wetland coordinated with the surrounding campus environment. As an important link in the water resource recovery system, a filtering mechanism needs to be used in cooperation.

[0003] The filtering mechanism usually sets up multi-stage filtering equipment to separately perform hierarchical filtering on sundries of different sizes in the recycled wastewater. As the volume of the sundries to be filtered decreases, the filtering gap of the filter element inside the filtering equipment also shrinks. Therefore, as the usage time increases, the small-aperture filter element in the filtering equipment is prone to blockage. The existing method is to clean the dirt through backwashing. However, since the filtering gap of the filter element is fixed, when some impurities are blocked too deeply, the effect of backwashing will be discounted, resulting in a reduction in the dirt cleaning effect and affecting the subsequent filtering efficiency, which has drawbacks in use. Summary of the Invention

[0004] In view of this, in view of the deficiencies of the existing technology, the main purpose of the present invention is to provide a medium water resource ecological recovery filtering device and system to solve the problem mentioned in the above background that since the filtering gap of the existing filter element is fixed, when some impurities are blocked too deeply, the effect of backwashing will be discounted, resulting in a reduction in the dirt cleaning effect and affecting the subsequent filtering efficiency, which has drawbacks in use.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0009] Further, an installation groove is formed on the outer wall of each side strip, and a pressing plate is provided inside each installation groove; several groups of elastic pieces are installed at equal intervals on the inner wall of each pressing plate, and two elastic pieces are symmetrically provided in each group.

[0010] Further, each group of elastic pieces penetrates through a through groove and is snap-connected to an adjusting blocking strip, and the through groove is formed on the inner wall of the installation groove.

[0011] Further, a compression film is provided on the outer wall of each side strip, and the inner wall of each compression film closely adheres to the outer wall of an elastic piece.

[0012] Further, each top cover is installed on the top of a filter housing, and a partition cover plate is installed at the bottom of each filter housing. At the same time, each partition cover plate is bolted to the top of a group of filter grilles.

[0013] Further, a first pressure gauge is installed on the top of each top cover.

[0014] Further, a second pressure gauge is installed on the upper part of the outer wall of each filter housing.

[0015] Further, each first outer connecting pipe is flange-connected to a first adapter pipe, and the end of each first adapter pipe is flange-connected to a first control valve.

[0016] Further, a second adapter pipe is installed in the middle of each of the first external connection pipes, a second control valve is installed in the middle of each second adapter pipe, and the end of each second adapter pipe is flange-connected to a flushing pump.

[0017] Further, the outer diameter of the inner connection pipe is smaller than the inner diameter of the base, and the central axes of the inner connection pipe, the base, the filter housing, and the sleeve are all on the same vertical line.

[0018] Further, a sewage valve is installed at the bottom of each of the bases.

[0019] A recovery system with a medium water resource ecological recovery and filtration device includes a basket strainer. There are two basket strainers, one of which is connected to a sump, and the other is connected to an adjustment tank. The sump is connected to a coagulation sedimentation tank, and the coagulation sedimentation tank is connected to a sludge tank.

[0020] Further, the adjustment tank is connected to a DMBR double-membrane internal circulation bioreactor, and the DMBR double-membrane internal circulation bioreactor; a blower is installed in the DMBR double-membrane internal circulation bioreactor, and the DMBR double-membrane internal circulation bioreactor is connected to the sludge tank and a clear water tank.

[0021] Further, the coagulation sedimentation tank is connected to an intermediate water tank, and the intermediate water tank is connected to a filtration mechanism; the filtration mechanism is connected to the clear water tank, and the clear water tank is connected to a disinfection system.

[0022] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

[0023] 1. In the present invention, a filter housing and filter grilles are provided. The filter grilles are distributed in a circular pattern. On the outer wall of each filter grille, two adjustable stop bars that can slide within a certain range are installed. And inside each side bar, a pressing plate and several elastic pieces are installed. In the initial state, due to the elastic force of the compression film pressing inward on the pressing plate, the elastic pieces on both sides are pushed to squeeze the adjustable stop bars on both sides, so that the distance between adjacent adjustable stop bars remains the smallest. When reverse flushing is required, the water flow squeezing the adjustable stop bars from the inside will push the adjustable stop bars to contract and slide inward into the side bar. At this time, the distance between adjacent adjustable stop bars will temporarily increase, ensuring that impurities that are too tightly clamped can quickly break away. At the same time, during the reverse flushing stage, the water pressure inside the filter grille is greater than the water pressure between the inside of the filter grille and the inner wall of the filter housing. The squeezed elastic pieces will bend and push the pressing plate outward. At the same time, the pressing plate pushes the compression film outward, and the compression film absorbs the pressure through its own elastic deformation. When the forward filtration process is carried out, at this time, the water pressure between the inside of the filter grille and the inner wall of the filter housing is greater than the water pressure inside the filter grille. Therefore, the water pressure will give the compression film an additional pressure, ensuring that the distance between adjacent adjustable stop bars can always remain the smallest during the filtration process, ensuring the most basic filtration function.

[0024] 2. In the present invention, a first pressure gauge and a second pressure gauge are provided. The bottom probe of the first pressure gauge penetrates through the partition cover plate and extends into the interior of the filter grille, while the probe of the second pressure gauge is located between the inner wall of the filter housing and the filter grille. When in use, the first pressure gauge and the second pressure gauge need to be kept open synchronously. The pressure difference between the first pressure gauge and the second pressure gauge is detected. When the pressure difference exceeds the set threshold value, reverse flushing is automatically carried out. The whole process is automatically controlled by the intelligent operation and maintenance system supporting the intermediate water system, improving the convenience of use.

[0025] 3. In the present invention, the overall structure of the filtration device is compact and can be connected to any filtration link in the filtration mechanism as a whole. The modular design improves the convenience of disassembly and assembly. And each single filtration device is provided with two relatively independent filter housings, and the effective filtration mechanism inside the filter housing is formed by the combination of multiple independent adjustable stop bars. As the use time increases, individual adjustable stop bars can be selected and replaced according to the wear state. Compared with the traditional integrated filtration mechanism that needs to be replaced as a whole after damage, the use cost is effectively reduced.

[0045] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in the figure, it includes a filter housing 1 and a top cover 12. There are two symmetrically arranged filter housings 1, and a base 16 is installed at the bottom of each filter housing 1; an inner connecting pipe 17 is installed inside each base 16, and the bottom of each inner connecting pipe 17 is connected to a first external connecting pipe 18; the end of each first external connecting pipe 18 penetrates through one side of the base 16, and a second external connecting pipe 19 is provided on the other side of each base 16; a sleeve 2 is provided inside each filter housing 1, and the bottom of each sleeve 2 is connected to the top of an inner connecting pipe 17; a group of filter grilles 3 is installed at the top of each sleeve 2, and several filter grilles 3 in each group are arranged at equal angles with respect to the vertical axis line of the sleeve 2; a side strip 4 is provided on the outer wall of each filter grille 3, and two limiting grooves 5 are symmetrically provided on both sides of each side strip 4, and an adjusting stop strip 6 is installed inside each limiting groove 5.

[0046] Specifically, the outer wall of the inner connecting pipe 17 is welded to the inner wall of the base 16 and is provided with a hollow to facilitate the smooth passage of water flow and sundries.

[0047] As a further description of this embodiment, during the forward filtration process, the filtered clean water is discharged through the sleeve 2, the inner connecting pipe 17, and the first external connecting pipe 18. When reverse flushing is required, the clean water is injected through the first external connecting pipe 18, the inner connecting pipe 17, and the sleeve 2.

[0048] In this embodiment, please refer to Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14 As shown in the figure, an installation groove 7 is opened on the outer wall of each side strip 4, and a pressing plate 9 is provided inside each installation groove 7; several groups of elastic pieces 10 are installed at equal intervals on the inner wall of each pressing plate 9, and two elastic pieces 10 are symmetrically provided in each group; each group of elastic pieces 10 penetrates through a through groove 8 and is engaged with an adjusting stop strip 6, and the through groove 8 is opened on the inner wall of the installation groove 7; a compression film 11 is provided on the outer wall of each side strip 4, and the inner wall of each compression film 11 closely adheres to the outer wall of an elastic piece 10.

[0049] Specifically, in the initial state, the compression film 11 gives an inward pressure to the pressing plate 9 through its own contraction, thereby pushing the elastic piece 10 to squeeze the corresponding adjusting stop strip 6 to ensure that the distance between two adjacent adjusting stop strips 6 is minimized.

[0050] As a further illustration of this embodiment, the compression film 11 is made of rubber and will deform when subjected to the continuous outward pressure of the pressing plate 9.

[0051] In this embodiment, please refer to Figure 5 , Figure 6 and Figure 7 As shown, each of the top covers 12 is installed on the top of a filter housing 1, and a partition cover plate 13 is installed at the bottom of each filter housing 1. At the same time, each partition cover plate 13 is bolted to the top of a set of filter grilles 3; a first pressure gauge 14 is installed on the top of each of the top covers 12; a second pressure gauge 15 is installed on the upper part of the outer wall of each filter housing 1.

[0052] Specifically, the internal water pressure of the filter grille 3 is monitored by the first pressure gauge 14, and the water pressure between the filter grille 3 and the filter housing 1 is monitored by the second pressure gauge 15.

[0053] As a further illustration of this embodiment, by monitoring the pressure difference between the first pressure gauge 14 and the second pressure gauge 15, automatic control of backwashing is carried out by comparing with the set pressure difference threshold.

[0054] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 As shown, each of the first outer connecting pipes 18 is flange-connected to a first adapter pipe 21, and the end of each first adapter pipe 21 is flange-connected to a first control valve 22; a second adapter pipe 23 is installed in the middle of each of the first outer connecting pipes 18, and a second control valve 25 is installed in the middle of each second adapter pipe 23. At the same time, the end of each second adapter pipe 23 is flange-connected to a flushing pump 24.

[0055] Specifically, during the process of forward filtration, the flushing pump 24 and the second control valve 25 are kept closed, and the first control valve 22 needs to be kept open.

[0056] As a further illustration of this embodiment, when performing backwashing, the flushing pump 24 is started, and the second control valve 25 needs to be opened simultaneously and the first control valve 22 needs to be closed.

[0057] In this embodiment, please refer to Figure 5 , Figure 6 and Figure 7 As shown, the outer diameter of the inner connecting pipe 17 is smaller than the inner diameter of the base 16, and the axis lines of the inner connecting pipe 17, the base 16, the filter housing 1, and the sleeve 2 are all on the same vertical straight line; a drain valve 20 is installed at the bottom of each of the bases 16.

[0058] More specifically, when performing forward filtration, the centrifugal pump 27 needs to be started, and the third control valve 26 is kept in an open state, and sewage is injected into the filter housing 1 through the second external pipe 19 .

[0059] As a further explanation of this embodiment, when backwashing is required, the centrifugal pump 27 and the third control valve 26 need to be closed at the same time, and the sewage valve 20 needs to be opened to discharge sewage.

[0060] Please refer to Figure 14 As shown, a recycling system with ecological recycling and filtration equipment for reclaimed water resources includes a basket grille 101, wherein two basket grilles 101 are provided, and one of the basket grilles 101 is connected to a water collection tank 102, while the other basket grille 101 is connected to a regulating tank 103; the water collection tank 102 is connected to a coagulation sedimentation tank 106, and the coagulation sedimentation tank 106 is connected to a sludge tank 107.

[0061] Specifically, the basket grille 101 is disposed at the front of the water collection tank 102 and needs to be lifted up by workers to salvage garbage. The basket grille 101 is used to filter and recycle large volumes of garbage in the water.

[0062] As a further explanation of this embodiment, the wastewater in the collection tank 102 is pumped into the coagulation sedimentation tank 106 through a lifting pump. The coagulation sedimentation tank 106 consists of two parts: a reaction tank and a sedimentation tank. The wastewater will first enter the reaction tank in the coagulation sedimentation tank 106, and a pipeline mixer needs to be set at the outlet section of the lifting pump to add coagulants and flocculants. After the water and the agent fully react, the particulate matter in the wastewater is flocculated into larger pieces of suspended matter, which can remove most of the suspended matter. Subsequently, the treated wastewater is separated from the mud and water by sedimentation in the sedimentation tank in the coagulation sedimentation tank 106. The sedimentation tank in the coagulation sedimentation tank 106 adopts an inclined tube sedimentation tank, and the supernatant of the sedimentation tank flows into the intermediate water tank by gravity. A lifting pump is set in the intermediate water tank to lift the wastewater to the intermediate water tank 108, and the generated sludge enters the sludge tank 107.

[0063] In this embodiment, please refer to Figure 14 As shown, the regulating tank 103 is connected to the DMBR double-membrane internal circulation bioreactor 104, and the DMBR double-membrane internal circulation bioreactor 104; a blower 105 is installed in the DMBR double-membrane internal circulation bioreactor 104, and the DMBR double-membrane internal circulation bioreactor 104 is connected to the sludge tank 107 and the clear water tank 110.

[0064] Specifically, after pretreatment in the regulating tank 103, the sewage enters the DMBR dual-membrane internal circulation bioreactor 104. The water after aerobic aeration and biological treatment is pumped out after being filtered by the filter membrane. It uses a membrane separation device to intercept the activated sludge and macromolecular organic substances in the biochemical reaction tank. The interior of the DMBR dual-membrane internal circulation bioreactor 104 can be subdivided into a biofilm reaction zone and a microfiltration membrane filtration zone. The mixed liquid forms an internal circulation between the two zones under the action of the aeration airflow generated by the blower 105. The biofilm reaction zone is equipped with a water distribution device, biofilm fillers, an aeration device, and an intake electric valve. The microfiltration membrane filtration zone is equipped with an immersed microfiltration membrane module, an aeration flushing device, and an intake electric valve.

[0065] As a further illustration of this embodiment, the influent enters the biofilm reaction zone evenly through the water distribution device. The control system intermittently opens the intake electric valve of the packed biofilm reaction zone to alternately form an anaerobic-anoxic-aerobic environment, completing the aerobic nitrification and phosphorus uptake, anoxic denitrification reaction, and anaerobic phosphorus release reactions of microorganisms, achieving the effect of nitrogen and phosphorus removal. The mixed liquid after the reaction forms an internal circulation under the action of the airflow, flows through the microfiltration membrane filtration zone, and the detached biofilm and particulate matter are intercepted by the microfiltration membrane and returned to the biofilm reaction zone with the water flow. The clear water passes through the microfiltration membrane module and converges into the water collection device, and is pumped out by the self-priming pump.

[0066] In this embodiment, please refer to Figure 14 As shown, the coagulation sedimentation tank 106 is connected to the intermediate water tank 108, and the intermediate water tank 108 is connected to the filtration mechanism 109; the filtration mechanism 109 is connected to the clear water tank 110, and the clear water tank 110 is connected to the disinfection system 111.

[0067] Specifically, the water after treatment is filtered in multiple layers by the filtration mechanism 109.

[0068] As a further illustration of this embodiment, after filtration, sterilization and disinfection are carried out by the disinfection system 111, and the purified water after disinfection can be recycled.

[0069] Working principle of the filtration device in the present invention: Connect the water inlet ends of two centrifugal pumps 27 to the sewage conveying pipeline, connect the water inlet ends of two flushing pumps 24 to the purified water output pipeline, connect the first control valve 22 to the purified water output pipeline, and connect two sewage valves 20 to the wastewater recovery pipeline. During forward filtration, start the centrifugal pumps 27 and open the corresponding third control valves 26. Pressurize and inject the sewage into the interior of the base 16 and the filter housing 1 through the second outer connection pipe 19 by the centrifugal pumps 27. Subsequently, the sewage passes through the gaps between the adjusting baffles 6 and enters the interior of the filter grille 3. Then, it is injected into the first adapter pipe 21 through the sleeve 2, the inner connection pipe 17, and the first outer connection pipe 18 in sequence, and then discharged through the first control valve 22. The impurities in the water are blocked outside the adjusting baffles 6.

[0070] Start the first pressure gauge 14 and the second pressure gauge 15 simultaneously. When the pressure values monitored by the first pressure gauge 14 and the second pressure gauge 15 exceed the set threshold, automatically close the first control valve 22, the third control valve 26, and the centrifugal pumps 27. At the same time, start two flushing pumps 24 and open the corresponding second control valves 25. Pressurize and inject the purified water into the interior of the filter grille 3 through the first outer connection pipe 18, the inner connection pipe 17, and the sleeve 2 by the flushing pumps 24. During this process, the water flow carries the impurities blocked between the adjusting baffles 6 and passes through the adjusting baffles 6 and injects into the filter housing 1. At this time, start the sewage valve 20 and discharge the wastewater generated during backwashing.

[0071] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
