Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, and in particular to a water ecological treatment device and method. Background Art

[0002] Water pollution control is a very important part of environmental governance. Factories have their own independent sewage purification standards, and the treatment of domestic sewage in cities is much more troublesome. It is mainly through various pipes and rivers to guide the sewage and then centrally treat it. However, this will also lead to sewage in some waters. For example, domestic sewage in cities flows through sewers to some small rivers, lakes, ponds and other waters, which will cause eutrophication in the waters, seriously endanger the lives of various animals and plants in the water, and cause serious damage to the water ecological environment.

[0003] In such seriously polluted waters, not only is the water itself seriously polluted, but there is also a large amount of silt deposited at the bottom of the water body. The silt is still rich in a large number of nutrients, so even if the water is changed many times, the water quality will still be polluted quickly. Planting specific microorganisms in the water body to purify water is difficult to penetrate into the silt, which is only a temporary solution. And because the silt is large in volume, it is also difficult to transfer it to other places.

[0004] CN210764605U discloses a device for injecting microorganisms by breaking up the riverbed mud, which discloses using impact force to infiltrate microorganisms into the mud. However, during the impact process, most microorganisms will float again in the water body and cannot be well fixed inside the mud. CN113620441A discloses an in-situ water treatment method, which discloses that the impact force of an aeration and oxygenation high-pressure nozzle can expose the surface layer of the mud at the bottom of the polluted water source area, but cannot fix the microorganisms well. The above methods are difficult to efficiently fix microorganisms inside the mud, and it is difficult to effectively treat the inside of the mud.

[0005] In summary, it is necessary to design a more efficient and lower-cost water ecological restoration device and method. Summary of the invention

[0006] The object of the present invention is to provide a water ecological treatment device and method, which can treat polluted water more efficiently and at a lower cost.

[0007] An embodiment of the present invention is achieved through the following technical solutions: the water ecological treatment equipment of the present invention includes a hull, an aeration device arranged on the lower side of one end of the hull, and a net-laying device arranged on the lower end of the other end of the hull; the aeration device includes a pair of vertically arranged first support rods, a first fixed shaft connected to the lower end of the first support rod, a first sleeve rotatably connected to the first fixed shaft, a plurality of aeration tubes distributed circumferentially around the first sleeve, aeration holes opened on the side walls of the aeration tubes, and an air supply device connected to the aeration tubes; the net-laying device includes a pair of vertically arranged second support rods, a second fixed shaft connected to the second support rods, a second sleeve rotatably connected to the second fixed shaft, a plurality of pressing rods distributed circumferentially around the second sleeve, a net roller arranged on the lower side of the hull, and a strain net rolled on the net roller, and the strain net is arranged to bypass the pressing rods.

[0008] Furthermore, the first sleeve is connected to the aeration pipe through a first connecting rod.

[0009] Furthermore, the first fixed shaft is a hollow structure and is connected to the air supply device, the first connecting rod is a hollow structure, and the first connecting rod is used to connect the aeration pipe and the first sleeve; a vent hole is opened on the lower end wall of the first fixed shaft, and the vent hole corresponds to the first connecting rod.

[0010] Furthermore, the air supply device includes an air compressor arranged on the hull, and an air duct connected to the air compressor, and the air duct is communicated with the interior of the first fixed shaft.

[0011] Furthermore, an aeration head is provided at the aeration hole.

[0012] Furthermore, the pressing rod and the second sleeve are connected via a second connecting rod; a plurality of semicircular pressing plates are provided on the outer wall of the pressing rod, and the openings of the pressing plates are arranged toward a side away from the pressing rod.

[0013] Furthermore, the bacterial strain net includes a mesh body and bacterial strains arranged on the mesh body; the mesh body is made of plastic fibers.

[0014] Furthermore, a pair of connecting pipes are provided at both ends of the hull, and the first supporting rod and the second supporting rod are both slidably disposed in the connecting pipes.

[0015] Furthermore, a plurality of plastic nails are provided on one side of the spawn net away from the pressing rod.

[0016] The present invention also provides a water ecological treatment method based on the above water ecological treatment equipment, comprising the following steps:

[0017] (1) Determine the water depth and silt depth of the water area requiring water treatment;

[0018] (2) Determine the required bacterial species based on the nutrient content in the sludge, and attach the corresponding bacterial species to the bacterial species net;

[0019] (3) using an aeration device at the front end of the hull to aerate the water body and the silt at the bottom of the water body, and the air pressure released by the aeration pipe sprays multiple strip-shaped grooves on the silt;

[0020] (4) inserting the strain net containing the strain into the groove of step (3) through the net-laying device at the rear end of the hull;

[0021] (5) When the water quality and sludge purification meet the expectations, the bacterial strain net can be removed from the water body.

[0022] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects: the water ecological treatment equipment and method of the present invention can not only aerate the water body and sludge through the aeration device, increase the dissolved oxygen in the water body, and improve the reproduction of aerobic bacteria, but also can impact a strip-shaped groove in the sludge through the aeration of the aeration pipe, and then the strain net can be pressed into the groove through the pressing rod in the net-laying device. As the aeration ends, the water body gradually becomes still, and the sludge in the water body will gradually sink to the bottom, and then the strain net will be closed again. At this time, the strain will continue to grow and reproduce in the sludge, and quickly consume the nutrients in the sludge, so as to achieve the purification effect of the water body. After a certain period of time, the strain net can be taken out of the water body and reused many times. In this way, the purification and restoration of the water body and the water ecology can be achieved in a more natural way. The whole process has a high degree of automation, does not require manual burying of the net, and can be reused, does not need to dig out the sludge, and does not need to find a place to store the sludge, so the operation is simpler and the cost is lower.

[0036] Example 1

[0037] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 6As shown, the water ecological treatment equipment of this embodiment includes a hull 30, an aeration device 10 arranged at the lower side of one end of the hull 30, and a net-laying device 20 arranged at the lower end of the other end of the hull 30; the aeration device 10 includes a pair of vertically arranged first support rods 11, a first fixed shaft 12 connected to the lower end of the first support rod 11, a first sleeve 13 rotatably connected to the first fixed shaft 12, a plurality of aeration pipes 14 distributed circumferentially around the first sleeve 13, and a first sleeve 13 provided at the bottom of the aeration pipe 13. 4, and an aeration hole on the side wall, and an air supply device connected to the aeration pipe 14; the net-laying device 20 includes a pair of vertically arranged second support rods 21, a second fixed shaft 22 connected to the second support rods 21, a second sleeve 23 rotatably connected to the second fixed shaft 22, a plurality of pressing rods 24 distributed in a circle around the second sleeve 23, a net-winding roller 29 arranged on the lower side of the hull 30, and a bacterial seed net 27 wound on the net-winding roller 29, and the bacterial seed net 27 is arranged around the pressing rods 24. Specifically, the aeration device 10 can not only aerate the water body and the silt, increase the dissolved oxygen in the water body, and improve the reproduction of aerobic bacteria, but also can impact a strip-shaped groove in the silt through the aeration of the aeration pipe 14, and then the strain net 27 can be pressed into the groove by the pressing rod 24 in the net-laying device 20. As the aeration ends, the water body gradually becomes still, and the silt in the water body will gradually sink to the bottom, and then the strain net 27 will be closed again. At this time, the strain will continue to grow and reproduce in the silt, and quickly consume the nutrients in the silt, so as to achieve the effect of purifying the water body. After a certain period of time, the strain net 27 can be taken out of the water body and reused many times. In this way, the purification and restoration of the water body and the water ecology can be achieved in a more natural way. The whole process has a high degree of automation, does not require manual burying of the net, and can be reused, does not need to dig out the silt, and does not need to find a place to store the silt, so the operation is simpler and the cost is lower. It should be noted that the end of the bacterial net 27 needs to be fixed to the bottom of the water first, and then during the movement of the hull 30, the bacterial net 27 is gradually laid in the mud under the action of the pressing rod 24, wherein the bacterial net 27 mainly includes a first fiber parallel to the pressing rod 24 and a second fiber perpendicular to the pressing rod 24, wherein a large number of bacterial species are mainly concentrated on the first fiber, so the first fiber is also thicker, and it is only necessary to bury the first fiber in the groove of the mud. In addition, since there are many and complex devices under the hull 30, the hull 30 itself does not need to have power, and can be towed on the shore or using a towing boat, which can also better ensure that the hull 30 travels in a straight line. For this reason, the rotation of the first sleeve 13 and the second sleeve 23 does not require the use of additional power, and can rotate automatically with the movement of the hull 30.

[0038] In this embodiment, the first sleeve 13 is connected to the aeration pipe 14 through the first connecting rod 15. The first fixed shaft 12 is a hollow structure and is connected to the air supply device. The first connecting rod 15 is a hollow structure. The first connecting rod 15 is used to connect the aeration pipe 14 and the first sleeve 13. The lower end wall of the first fixed shaft 12 is provided with a vent hole, which corresponds to the first connecting rod 15. Specifically, during aeration, not all aeration pipes 14 may be aerated at the same time, but only one aeration pipe 14 is in an aeration state at a time, so that the aeration pipe 14 has a greater impact force and can better disperse the sludge. The lower end of the first fixed shaft 12 is provided with a vent hole. Therefore, only when the aeration pipe 14 rotates to the lower end of the first fixed shaft 12, it can be connected to the first fixed shaft 12 through the first connecting rod 15, and finally connected to the air supply device, and the air supply device sends high-pressure gas into the aeration pipe 14.

[0039] The air supply device in this embodiment includes an air compressor 18 disposed on the hull 30, and an air guide pipe 17 connected to the air compressor 18, and the air guide pipe 17 is communicated with the interior of the first fixed shaft 12. An aeration head 16 is provided at the aeration hole.

[0040] The pressing rod 24 and the second sleeve 23 in this embodiment are connected by a second connecting rod 25; a plurality of semicircular pressing plates 26 are provided on the outer wall of the pressing rod 24, and the openings of the pressing plates 26 are arranged toward the side away from the pressing rod 24. Specifically, during the net laying process, the pressing plates 26 on the pressing rod 24 can buckle the bacterial seed net 27 and press the bacterial seed net 27 into the sludge.

[0041] The bacterial strain net 27 in this embodiment includes a net-shaped body and bacterial strains arranged on the net-shaped body; the net-shaped body is made of plastic fiber. Specifically, the main function of the net-shaped body is to carry bacterial strains, so it is made of plastic for easy reuse.

[0042] In this embodiment, a pair of connecting pipes 31 are provided at both ends of the hull 30, and the first support rod 11 and the second support rod 21 are both slidably disposed in the connecting pipes 31. Specifically, the aeration device 10 and the net-laying device 20 are both detachable structures, that is, they can be directly modified and installed on the existing hull 30, and there is no need to produce a special hull 30, so that the production cost of the device is lower, and when not in use, the hull 30 can be used as a conventional ship, wherein the connecting pipe 31 is provided to facilitate the adjustment of the height of the first support rod 11 and the second support rod 21 according to the depth of the water body and the silt.

[0043] The spawn net 27 in this embodiment is provided with a plurality of plastic nails 28 on one side away from the pressing rod 24. Specifically, the use of the plastic nails 28 can better fix the spawn net 27 in the mud.

[0044] Example 2

[0045] This embodiment provides a water ecological treatment method based on the water ecological treatment equipment of embodiment 1, comprising the following steps:

[0046] (1) Determine the water depth and silt depth of the water area requiring water treatment;

[0047] (2) Determine the required bacterial species based on the nutrient content in the sludge, and attach the corresponding bacterial species to the bacterial species net;

[0048] (3) using an aeration device at the front end of the hull to aerate the water body and the silt at the bottom of the water body, and the air pressure released by the aeration pipe sprays multiple strip-shaped grooves on the silt;

[0049] (4) inserting the strain net containing the strain into the groove of step (3) through the net-laying device at the rear end of the hull;

[0050] (5) When the water quality and sludge purification meet the expectations, the bacterial strain net can be removed from the water body.

[0051] In summary, the water ecology treatment equipment and method of the present invention can not only aerate the water body and silt through the aeration device, increase the dissolved oxygen in the water body, and improve the reproduction of aerobic bacteria, but also can impact strip grooves in the silt through the aeration of the aeration pipe, and then the strain net can be pressed into the groove by the pressing rod in the net-laying device. As the aeration ends, the water body gradually becomes still, and the silt in the water body will gradually sink to the bottom, and then the strain net will be closed again. At this time, the strain will continue to grow and reproduce in the silt, and quickly consume the nutrients in the silt, so as to achieve the purification effect of the water body. After a certain period of time, the strain net can be taken out of the water body and reused many times. In this way, the purification and restoration of the water body and the water ecology can be achieved in a more natural way. The whole process has a high degree of automation, does not require manual burying of the net, and can be reused, does not need to dig out the silt, and does not need to find a place to store the silt, so the operation is simpler and the cost is lower.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
