Description

Technical Field

[0001] The invention belongs to the technical field of water environment management, and in particular relates to an intelligent control system for a horizontal flow artificial wetland. Background Art

[0002] Artificial wetland technology is an engineering application technology that simulates natural wetland systems to treat river sewage. It purifies upstream river sewage through the synergistic effects of physics, chemistry and biology under a specific water environment. It has the advantages of low investment, short construction period, low operating cost, good sewage treatment effect, and beautification of the landscape environment. It is used in the field of black and smelly river management and water environment ecological restoration technology.

[0003] According to the direction of water flow in artificial wetlands, artificial wetlands are divided into horizontal flow artificial wetlands and vertical flow artificial wetlands. Horizontal flow artificial wetlands are better than vertical flow artificial wetlands in removing organic matter in sewage, but the operation and control of horizontal flow wetlands are relatively complex.

[0004] With the change of seasons, the growth of microorganisms and plants, and the changes in the quality and quantity of water from upstream, artificial wetlands need to be adjusted in time. However, most artificial wetlands are currently regulated in a relatively extensive manner, and the liquid level of artificial wetlands cannot be accurately adjusted in time. When the liquid level is too high, the artificial wetland will produce a too thick aerated zone, and when the liquid level is too low, the treatment effect cannot be achieved. If the liquid level is adjusted too slowly, the wetland plants cannot be controlled for rooting and seedling cultivation.

[0005] Although artificial wetlands have many unique advantages, since artificial wetlands are a passive way of oxygen transfer, natural reoxygenation and oxygen provided by plant roots cannot provide sufficient dissolved oxygen for artificial wetlands, resulting in low dissolved oxygen content in the system, which restricts the treatment effect of artificial wetlands. Summary of the invention

[0011] Furthermore, the liquid separation component includes a plurality of rotating liquid plates connected end to end from bottom to top; the rotating liquid plate includes a liquid plate body, an upper fold edge arranged on the upper side of the liquid plate body, and a lower fold edge arranged on the lower side of the liquid plate body, the upper fold edge and the lower fold edge have opposite bending directions, and the lower side of the upper fold edge of the rotating liquid plate is connected to the upper side of the lower fold edge of the adjacent rotating liquid plate.

The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0027] like Figures 1 to 6 As shown, this embodiment provides a horizontal flow artificial wetland intelligent control system, including an inlet area 1, a filtration area 2 and an outlet area 3 connected in sequence along the horizontal direction, a water quality monitoring unit 4 for monitoring the water quality of the inlet area 1 and the outlet area 3, and an aeration unit 5 arranged in the inlet area 1 and connected to the water quality monitoring unit 4; the inlet area 1 is connected to the artificial wetland and is used to store the discharged water of the artificial wetland; the filtration area 2 can filter the water flowing into the inlet area 1 and discharge it into the outlet area 3; the water quality monitoring unit 4 can start the aeration unit 5 to aerate the inlet area 1 when it is monitored that the water quality parameters of the inlet area 1 and the outlet area 3 are not within a preset range.

[0028] In this embodiment, a water quality monitoring unit 4 is provided to monitor the water quality of the water inlet area 1 and the water outlet area 3 in real time, such as the DO, COD, NH3-N, and TP content in the water, and preset values ​​of water quality indicators are set. When the water quality monitoring unit 4 detects that the water quality indicators of the water inlet area 1 and the water outlet area 3 are not within the preset range, it means that the water quality is poor and the dissolved oxygen content is low. At this time, the aeration unit 5 in the water inlet area 1 is started to aerate the water inlet area 1 to increase the oxygen content in the water inlet area 1. Through the active oxygen supply method of aeration, sufficient dissolved oxygen is provided for the artificial wetland, the purpose of oxygenating the artificial wetland system is achieved, and the ability of microorganisms in the artificial wetland system to degrade pollutants in the water is improved, thereby enhancing the removal efficiency of the artificial wetland for pollutants in the water and ensuring the treatment effect of the artificial wetland.

[0029] In a specific embodiment, the water quality monitoring unit 4 is used to detect the water quality of the water inlet area 1 and the water outlet area 3, such as the water inlet area: COD≤200mg / l, NH3-N≤25mg / l, TP≤5mg / l, DO≥3mg / l; the water outlet area: COD≤30mg / l, NH3-N≤2.5mg / l, TP≤0.3mg / l, DO≥3mg / l. As long as any parameter is not within the preset range, the aeration unit 5 will be started to aerate the water inlet area 1. When the water quality reaches the preset value, the aeration unit 5 will be turned off and the aeration will be stopped.

[0030] The horizontal flow artificial wetland intelligent control system in this embodiment also includes an alarm unit connected to the water quality monitoring unit 4, which can activate the alarm unit and the aeration unit 5 when the water quality parameters of the water inlet area 1 and the water outlet area 3 are not within the preset range. The design of the alarm unit is convenient for the staff to monitor the water quality of the artificial wetland in real time.

[0031] The aeration unit 5 in this embodiment includes an aeration pipe 501 disposed at the bottom of the water inlet area 1, and a blower 502 connected to the aeration pipe 501 for controlling aeration of the aeration pipe 501. The blower 502 is used to aerate the water inlet area 1 through the aeration pipe 501, which is conducive to replenishing the oxygen content of the water inlet area 1 in time.

[0032] In this embodiment, the filter area 2 includes a first filter area 201, a filler area 202, and a second filter area 203 arranged in sequence in the horizontal direction; the first filter area 201 and the second filter area 203 are symmetrically arranged, the water inlet area 1 is connected to the upper end of the first filter area 201, and the lower end of the second filter area 203 is connected to the water outlet area 3. The water inlet area 1 is connected to the upper end of the first filter area 201, which is conducive to the upper water of the water inlet area 1 flowing into the first filter area 201 to ensure that the water level of the water inlet area 1 and the first filter area 201 are flush, and the lower end of the second filter area 203 is connected to the water outlet area 3, which is conducive to the discharge of sewage at the bottom of the second filter area 203. In this embodiment, by setting a plurality of filter areas connected in sequence, it is conducive to improving the absorption capacity of pollutants in water, thereby enhancing the removal efficiency of pollutants in water by artificial wetlands.

[0033] In a preferred embodiment, the first filter area 201 is filled with pebbles, the second filter area 203 is filled with pebbles, and the filler area 202 includes a first filler area 221, a second filler area 222, and a third filler area 223 from top to bottom. The first filler area 221 is filled with coal slag, the second filler area 222 is filled with oyster shells, and the third filler area 223 is filled with volcanic rocks. The first filter area 201 and the second filter area 203 are filled with pebbles to intercept large particle impurities such as suspended matter colloids in the water. When filtering impurities, surface blockage can be overcome better, and the interception capacity of the filter area 2 can be fully utilized. It can provide high-quality filtered water at a higher filtration rate, and has the characteristics of corrosion resistance and long service life. The diameter of the pebbles is preferably 32mm-64mm. Pebbles with large diameters are conducive to the passage of water and the precipitation of impurities. The first filling area 221 and the second filling area 222 are filled with coal slag and oyster shells, respectively, to achieve effective utilization of waste, wherein the diameter of the coal slag is preferably 2mm-12mm, and the diameter of the oyster shell is preferably 12mm-24mm. The upper filling material is selected from small particles of coal slag and oyster shells, which are beneficial to the fixation of plant roots on the one hand, and have a good adsorption effect on the other hand. The third filling area 223 is filled with volcanic rock, which has a large specific surface area, good water permeability, and low price. The diameter of the volcanic rock is preferably 24mm-32mm. The large-particle volcanic rock has a large porosity, which is beneficial to the passage of water and prevents the occurrence of overflow.

[0034] The horizontal flow artificial wetland intelligent control system of this embodiment further includes a first water inlet pipe 10 for connecting the artificial wetland and the water inlet area 1, and a second water inlet pipe 11 for connecting the water inlet area 1 and the first filtering area 201. The center elevation of the first water inlet pipe 10 is 30-50 mm higher than the center elevation of the second water inlet pipe 11. The center elevation of the first water inlet pipe 10 is higher than the center elevation of the second water inlet pipe 11, which can prevent the water in the water inlet area 1 from flowing back to the artificial wetland.

[0035] The horizontal flow artificial wetland intelligent control system provided in this embodiment also includes a liquid separation component 6 arranged in the water outlet area 3 and dividing the water outlet area 3 into two horizontal parts, and a control unit 7 for controlling the height change of the liquid separation component 6, which is used to connect the second filtration area 203 and the water outlet area 3. The water outlet pipe 8 and the drain pipe 9 are arranged on the side wall of the water outlet area 3, and the water outlet pipe 8 and the drain pipe 9 are respectively located on opposite sides of the liquid separation component 6.

[0036] In this embodiment, the water outlet area 3 is divided into two independent parts by the liquid separation component 6, namely, the first water outlet area close to the second filter area 203 and the second water outlet area far from the second filter area 203. The water outlet pipe 8 is arranged in the first water outlet area, and the drain pipe 9 is arranged in the second water outlet area. The first water outlet area is connected with the artificial wetland to ensure the level of the liquid level. Therefore, when the liquid level of the artificial wetland needs to be adjusted, the height of the liquid separation component 6, that is, the liquid level of the first water outlet area, is changed to achieve accurate adjustment of the liquid level of the artificial wetland. Specifically, when the liquid level of the artificial wetland is high, the height of the liquid separation component 6 is reduced to the ideal target value by the control unit 7. At this time, the water in the first water outlet area flows to the second water outlet area, and the water in the second filter area 203 flows to the first water outlet area until the liquid level drops to the height of the liquid separation component 6; similarly, when the liquid level of the artificial wetland is low, the control unit 7 raises the height of the liquid separation component 6 to the ideal target value. As the upstream water is added to the artificial wetland and gradually raises the liquid level, the liquid level of the first water outlet area also gradually rises to the target liquid level. The height change of the liquid separation component 6 is controlled by the control unit 7 to realize intelligent and precise control of the liquid level of the artificial wetland. When the water quality deteriorates, the liquid level is increased to increase the hydraulic retention time, thereby improving the removal effect of the artificial wetland on pollutants.

[0037] In the horizontal flow artificial wetland intelligent control system provided in this embodiment, the outlet pipe 8 and the drain pipe 9 are both arranged at the lower end of the outlet area 3. The outlet pipe 8 is arranged at the lower end of the outlet area 3, and the liquid level of the artificial wetland is equal to that of the first outlet area under the same atmospheric pressure by using the U-shaped pipe principle; the drain pipe 9 is arranged at the lower end of the outlet area 3, which is conducive to the discharge of water in the second outlet area.

[0038] The liquid separation assembly 6 in this embodiment includes a plurality of rotating liquid plates 601 connected end to end from bottom to top; the rotating liquid plate 601 includes a liquid plate body 611, an upper fold 612 disposed on the upper side of the liquid plate body 611, and a lower fold 613 disposed on the lower side of the liquid plate body 611, wherein the upper fold 612 and the lower fold 613 are bent in opposite directions, and the lower side of the upper fold 612 of the rotating liquid plate 601 is connected to the upper side of the lower fold 613 of the adjacent rotating liquid plate 601. The upper fold 612 of the rotating liquid plate 601 is connected to the lower fold 613 of the adjacent rotating liquid plate 601 by interlocking with each other, thereby ensuring the sealing between the adjacent rotating liquid plates 601.

[0039] In a preferred embodiment, the rotating liquid plate 601 further includes a sealing strip disposed on the lower side of the upper fold 612 and a sealing strip disposed on the upper side of the lower fold 613. By respectively disposing sealing strips on the upper fold 612 and the lower fold 613, the sealing performance of the upper fold 612 of the rotating liquid plate 601 and the lower fold 613 of the adjacent rotating liquid plate 601 is effectively ensured, and the rotating liquid plate 601 is ensured to be watertight, thereby ensuring the sealing performance of the first water outlet area, and avoiding the problem that the water in the first water outlet area flows into the second water outlet area through the gap of the liquid separation component 6. In a preferred embodiment, the sealing strip is a waterproof sealing strip, such as a rubber sealing ring.

[0040] In the intelligent control system of horizontal flow artificial wetland in this embodiment, the rotating liquid plate 601 also includes a rotating central axis 614 arranged on the liquid plate body 611 and capable of driving the rotating liquid plate 601 to deflect, and a gear 615 sleeved on the rotating central axis 614; the control unit 7 includes a transmission rod 701 meshed with the gear 615 of the rotating liquid plate 601 and a driving component 702 that controls the transmission rod 701 to move up and down to drive the rotating liquid plate 601 to deflect. The driving component 702 drives the transmission rod 701 to move up and down, and the up and down movement of the transmission rod 701 drives the rotation of the gear 615 and then drives the deflection of the rotating liquid plate 601, thereby realizing the regulation of the liquid level of the horizontal flow artificial wetland. The height adjustment of the liquid separation component 6 is realized by driving the deflection of the rotating liquid plate 601 by the control unit 7, which has the characteristics of simple operation, convenient use, and high height adjustment accuracy.

[0041] Specifically, when the transmission rod 701 moves from top to bottom, with the help of the meshing connection between the transmission rod 701 and the rotating liquid plate 601, each rotating liquid plate 601 is driven to deflect in turn. When the uppermost rotating liquid plate 601 deflects, a gap is generated between the first rotating liquid plate 601 and the second rotating liquid plate 601. At this time, the height of the second rotating liquid plate 601 determines the liquid level; similarly, when the transmission rod 701 drives the second rotating liquid plate 601 to deflect, the first rotating liquid plate 601 is sealed and connected to the second rotating liquid plate 601, and there is a gap between the second rotating liquid plate 601 and the third rotating liquid plate 601. At this time, the height of the third rotating liquid plate 601 determines the liquid level. The liquid level gradually decreases as the transmission rod 701 moves from top to bottom; when the transmission rod 701 moves from bottom to top, the meshing connection between the transmission rod 701 and the rotating liquid plate 601 drives each rotating liquid plate 601 to deflect in turn. When the bottom rotating liquid plate 601 (non-fixed rotating liquid plate 601) deflects, a gap is generated between the rotating liquid plate 601 and the upper rotating liquid plate 601 adjacent to it. At this time, the height of the rotating liquid plate 601 determines the liquid level. When the transmission rod 701 continues to move upward, driving the adjacent upper rotating liquid plate 601 to deflect, the liquid level rises by the height of a rotating liquid plate 601. As the transmission rod 701 continues to move upward, the liquid level gradually rises. The meshing connection between the transmission rod 701 and the rotating liquid plate 601 effectively ensures the accuracy of the height adjustment of the liquid separation component 6, which helps to improve the water purification treatment effect of the horizontal flow artificial wetland.

[0042] In this embodiment, the liquid separation component 6 also includes a base disposed at the bottom of the water outlet area 3, and the base is connected to the lower fold 613 of the adjacent rotating liquid plate 601. The rotating liquid plate 601 is fixedly installed by setting the base, which effectively ensures the installation stability of the liquid separation component 6.

[0043] In a preferred embodiment, the rotating liquid plate 601 includes two gear teeth 615 disposed on both sides of the liquid plate body 611; the driving mechanism includes two transmission rods 701 respectively meshed with the two gear teeth 615, and the two transmission rods 701 are respectively in contact with the inner wall of the water outlet area 3. By respectively arranging two gear teeth 615 on both sides of the rotating liquid plate 601, and the two transmission rods 701 are respectively meshed with the two gears, the balance of the deflection of the rotating liquid plate 601 is effectively ensured.

[0044] In a preferred embodiment, the lower end of the transmission rod 701 is provided with a tooth groove meshing with the gear teeth 615. When the transmission rod 701 moves up and down to drive the rotating liquid plate 601 meshing therewith to deflect, the rotating liquid plate 601 can drive the rotating liquid plate 601 adjacent thereto to deflect, so as to change the height of the liquid separation component 6. In this embodiment, the tooth groove meshing with the gear teeth 615 is provided at the lower end of the transmission rod 701, so that the rotating liquid plate 601 at the lower end of the liquid separation component 6 is meshed with the transmission rod 701, thereby driving all the rotating liquid plates 601 to deflect.

[0045] In a specific embodiment, the effluent from the horizontal flow artificial wetland enters the outlet area 3 through the wetland outlet pipe 8, and the driving component 702 controls the transmission rod 701 to descend. When the transmission rod 701 descends, the teeth on the transmission rod 701 drive the rotating central axis 614 to rotate, and the rotation of the rotating central axis 614 drives the rotating liquid plate 601 to flip, and the liquid level in the wetland outlet area 3 drops. Finally, the effluent from the horizontal flow artificial wetland is discharged through the drain pipe 9.

[0046] The horizontal flow artificial wetland effluent enters the wetland effluent area 3 through the wetland effluent pipe 8, and the driving component 702 controls the transmission rod 701 to rise. When the transmission rod 701 rises, the teeth on the transmission rod 701 drive the rotating central axis 614 to rotate from bottom to top in sequence, and the rotation of the rotating central axis 614 drives the rotating liquid plate 601 to flip, and the liquid level in the wetland effluent area 3 rises. Finally, the horizontal flow artificial wetland effluent is discharged through the drain pipe 9.

[0047] The horizontal flow artificial wetland intelligent control system in this embodiment can realize the regulation of the artificial wetland winter ice cover insulation layer and the root control and seedling cultivation of wetland plants. The thickness of the winter ice cover insulation layer can be adjusted by raising the winter wetland operating liquid level. Since the plant roots grow at the apical end, the wetland operating liquid level is lowered by controlling the height of the liquid separation component through the control unit. The height of the liquid separation component is raised to raise the wetland operating liquid level above the roots of the wetland plants, and after the lateral roots appear in the plant roots, the height of the liquid separation component is lowered to keep the wetland operating liquid level in the middle of the plant roots at all times, thereby inducing the growth of the plant roots.

[0048] The horizontal flow artificial wetland intelligent control system in this embodiment has obvious advantages over the prior art: by regulating the liquid level of the horizontal flow artificial wetland, the problem of heat preservation operation of the horizontal flow artificial wetland system in cold winter and low temperature areas is solved, and the artificial wetland system's ability to purify pollutants in water in winter is improved; by accurately regulating the liquid level of the artificial wetland through the automatic control liquid level system, the problems of wetland plant root control and seedling cultivation and untimely and accurate wetland liquid level control are solved, the growth of plant roots is accelerated, and the absorption of pollutants in water by plant roots is improved, thereby improving the artificial wetland's ability to purify pollutants in water.
