Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture wastewater treatment, in particular to a device for filtering and desalting aquaculture wastewater in an integrated planting and breeding system. Background Art

[0002] In current agricultural production, irrigation technology, as a key factor to ensure the healthy growth of crops, is of self-evident importance. However, existing irrigation systems, such as drip irrigation and sprinkler irrigation, often encounter clogging problems during actual application. These clogs are often caused by two main reasons: one is excessive suspended solids in the irrigation water, and the other is crystallization clogging caused by high salt content in the water. These two problems not only affect the normal operation of the irrigation system, reduce irrigation efficiency, but also may have an adverse impact on crop growth.

[0003] During the irrigation process in the current integrated planting and breeding mode of aquaculture, this clogging problem is even more serious. The main reasons restricting the smooth promotion of the integrated planting and breeding mode are currently (1) unreasonable planting and breeding structure; (2) low utilization efficiency of manure and sewage; (3) low utilization of straw feed; (4) easy clogging of irrigation equipment in the consumption area; among which, the irrigation clogging problem in the planting consumption area is one of the main technical problems.

[0004] In the integrated planting and breeding mode, the water intake in the planting consumption area is mainly the biogas slurry effluent or the treated water of biogas slurry of aquaculture wastewater. The main reasons for frequent irrigation clogging include: (1) clogging problems caused by suspended solids introduced in biogas slurry or treated biogas slurry water. Usually, a large amount of suspended solids are contained in the biogas slurry of the farm, such as undigested feed residues, pig hair, pig skin and other impurities; (2) crystallization clogging problems caused by excessive salt content in biogas slurry or treated biogas slurry water. Taking a pig farm as an example, usually the salt content in the biogas slurry of a pig farm can reach a quite high level, and its conductivity usually exceeds 4000 μS / cm. These excessive salts not only easily cause clogging problems, but also are very difficult to handle once clogging occurs.

[0005] In the current technical system, there is no effective method to effectively solve the clogging of the irrigation system in the planting consumption area of the biogas slurry of the farm, which is also one of the common technical problems in the areas where the integrated planting and breeding mode is implemented. Usually, in order to solve the clogging problem of the irrigation system, farms will adopt physical filtration methods, but this method cannot effectively solve the problem. The main problem is that the suspended solids and particulate matters in the biogas slurry are often very small, and conventional filtration equipment is difficult to completely intercept, resulting in the clogging problem still existing. Summary of the Utility Model

[0006] In view of the above problems, the present application provides a device for filtering and desalting aquaculture wastewater in an integrated planting and breeding system to filter suspended solids and particulate matters in the biogas slurry.

[0040] See also Figures 1 to 5 This embodiment provides a device for filtering and desalting aquaculture wastewater in a farming and breeding system, comprising:

[0041] A mud bucket bin 10, wherein the mud bucket bin 10 has a mud bucket cavity 11 and a first opening 12 on the top, wherein the first opening 12 is communicated with the mud bucket cavity 11, wherein the mud bucket cavity 11 is used to contain mud and sand, and a liquid inlet through hole 13 communicated with the mud bucket cavity 11 is opened on the wall of the mud bucket bin 10;

[0042] A honeycomb filter bin 20, the honeycomb filter bin 20 is placed above the mud bucket bin 10; the honeycomb filter bin 20 has a plurality of honeycomb channels 22 separated by partitions 21, the honeycomb channels 22 are inclined channels, and one end of each of the honeycomb channels 22 is connected to the first opening 12;

[0043] The adsorption bin 30 includes a shell 31 and an adsorption rod 32. The shell 31 has an adsorption cavity 33. The adsorption rod 32 is placed in the adsorption cavity 33, and the adsorption rod 32 is connected to the shell 31. A liquid outlet hole 34 and a second opening 35 are provided on the wall of the shell 31. The second opening 35 and the liquid outlet hole 34 are both connected to the adsorption cavity 33. The second opening 35 is connected to one end of the plurality of honeycomb channels 22 away from the mud hopper bin 10.

[0044] The mud hopper bin 10 has the mud hopper cavity 11, and the top of the mud hopper bin 10 is provided with the first opening 12, and the first opening 12 is connected to the mud hopper cavity 11, and the first opening 12 is used to discharge the aquaculture waste liquid upward. The side wall of the mud hopper bin 10 is provided with the liquid inlet through hole 13, and the liquid inlet through hole 13 is used to introduce the aquaculture wastewater to be treated (such as biogas slurry) into the mud hopper cavity 11. The liquid inlet through hole 13 is connected to the liquid inlet pipeline, and the aquaculture wastewater can enter the mud hopper cavity 11 through the liquid inlet pipeline. When the aquaculture waste liquid enters the mud hopper cavity 11, the sludge and other impurities in the aquaculture waste liquid will settle at the bottom of the mud hopper cavity 11.

[0045] The sludge hopper bin 10 is used to preliminarily precipitate large particulate suspensions in the aquaculture wastewater, such as undigested feed residues, pig hairs, pig skins, etc. These large particulate substances will quickly settle to the bottom of the sludge hopper cavity 11 under the action of gravity, realizing preliminary solid-liquid separation.

[0046] The honeycomb filter bin 20 is placed above the sludge hopper bin 10. The partition plate 21 is placed in the honeycomb filter bin 20. A plurality of the partition plates 21 divide the cavity in the honeycomb filter bin 20 into a plurality of inclined honeycomb channels 22. One end of the honeycomb channel 22 is connected to the first opening 12 of the sludge hopper bin 10, and the other end faces the adsorption bin 30.

[0047] The wastewater preliminarily precipitated by the sludge hopper bin 10 enters the honeycomb filter bin 20 from the bottom and is further filtered through the inclined honeycomb channels 22. Since the honeycomb channels 22 are inclined, eddies and shear forces will be generated during the flow of the wastewater, which helps to remove finer suspended solids and particulate matters. At the same time, the inclined design also helps the natural flow of the wastewater and reduces the risk of blockage. Further, in the inclined honeycomb channels 22, the water flow forms a spiral flow, which helps to improve the contact efficiency between the suspended particles in the water and chemical agents (such as coagulants). The suspended solids and particulate matters fall along the honeycomb channels 22 into the lower sludge hopper cavity 11.

[0048] Further, the cross-section of the honeycomb channel 22 is hexagonal, and the hexagonal setting maximizes the contact area between the channels. When the wastewater passes through the hexagonal channels, it will be subjected to shear forces and eddy currents from multiple directions, which helps to further remove the suspended solids and particulate matters in the wastewater.

[0049] The adsorption bin 30 includes the housing 31 and a plurality of adsorption rods 32. An adsorption cavity 33 is provided in the housing 31, and the adsorption rods 32 are placed in the adsorption cavity 33 and fixedly connected to the housing 31. Further, the length of the adsorption rod 32 is adapted to the length or width of the adsorption cavity 33, that is, both ends of the adsorption rod 32 are in contact with the inner wall of the housing 31.

[0050] The liquid outlet through hole 34 and the second opening 35 are penetrated through the wall of the housing 31. The second opening 35 is connected to one end of a plurality of the honeycomb channels 22 far from the sludge hopper bin 10, that is, the waste liquid discharged from the end of the honeycomb channel 22 enters the adsorption cavity 33 from the second opening 35. Further, the second opening 35 has the following two implementation manners. One is that the caliber of the second opening 35 is larger and directly covers a plurality of the honeycomb channels 22. The other is that the caliber of the second opening 35 is small, and it is conducted to a plurality of the honeycomb channels 22 through pipelines and diversion units. The liquid outlet through hole 34 is used to discharge the treated wastewater.

[0051] The wastewater treated by the honeycomb filter chamber 20 enters the adsorption chamber 30. The adsorption rods 32 in the adsorption chamber 30 are usually made of materials with strong adsorption capacity (such as activated carbon, ion exchange resin, magnetic materials, etc.) and are used to adsorb the salts and other harmful substances in the wastewater. When the wastewater passes through the adsorption rods 32, the salts, metals, and harmful substances in it are effectively removed, thereby realizing the desalination and purification of the wastewater. Finally, the treated wastewater is discharged through the liquid outlet through-hole 34 for irrigation use.

[0052] In summary, the specific steps are as follows: Preliminary precipitation: The aquaculture wastewater first enters the mud hopper chamber 10 through the liquid inlet through-hole 13 and undergoes preliminary precipitation in the mud hopper cavity 11 to remove large particulate suspensions. Fine filtration: The wastewater after preliminary precipitation enters the honeycomb filter chamber 20 and undergoes fine filtration through the inclined honeycomb channels 22 to remove finer suspensions and particulate matters. Adsorption for desalination and removal of metals: The wastewater treated by the honeycomb filter chamber 20 enters the adsorption chamber 30 and contacts the adsorption rods 32 in the adsorption cavity 33. The adsorption rods 32 adsorb the salts and other harmful substances in the wastewater. The treated wastewater is discharged through the liquid outlet through-hole 34.

[0053] Different from the prior art, in the above technical solution, through the settings of the mud hopper chamber 10, the honeycomb filter chamber 20, and the adsorption chamber 30, the aquaculture wastewater can pass through the above chambers in sequence, realizing the preliminary precipitation, fine filtration of the aquaculture wastewater, and removal of harmful substances (such as salt ions and heavy metals) in the wastewater, thereby avoiding the blockage of pipelines by impurities or salt ions.

[0054] According to some embodiments of the present application, with reference to Figures 1 to 3 , the cross-sectional area of the bottom of the mud hopper cavity 11 is smaller than the cross-sectional area of the top of the mud hopper cavity 11. In some embodiments, it further includes: a cover body. A sewage discharge through-hole 14 is provided at the bottom of the mud hopper chamber 10, and the cover body covers the sewage discharge through-hole 14.

[0055] The mud hopper chamber 10 has an inverted conical or inverted frustum structure with the cross-sectional area of the bottom of the mud hopper cavity 11 smaller than that of the top. The inverted cone facilitates the rapid sedimentation of the wastewater in the mud hopper cavity 11, making it easier for large particulate suspensions to deposit at the bottom, thereby improving the sedimentation efficiency. Specifically, the wastewater forms a faster flow rate and a stronger vortex effect in the mud hopper cavity 11, which helps the rapid sedimentation of large particulate suspensions, thereby improving the sedimentation efficiency.

[0056] One sewage discharge through-hole 14 is provided at the bottom of the mud hopper chamber 10, and the sewage discharge through-hole 14 is used to discharge the sediment and impurities deposited at the bottom of the mud hopper cavity 11.

[0057] The sewage through-hole 14 is adapted to the cover body, and the cover body can be tightly covered on the sewage through-hole 14 to prevent wastewater from leaking from the sewage through-hole 14 in a non-sewage state. The cover body is fixed on the sewage through-hole 14 by means of threaded connection, snap connection or other sealing methods.

[0058] When the sediment and impurities deposited in the mud bucket cavity 11 accumulate to a certain extent, the cover body is opened, and the sediment is discharged through the sewage through-hole 14. The arrangement of the sewage through-hole 14 and the cover body at the bottom enables the sediment and impurities deposited at the bottom of the mud bucket cavity 11 to be conveniently discharged, reducing the maintenance difficulty and workload.

[0059] According to some embodiments of the present application, with reference to Figure 1 and Figure 5 , the second open end 35 and the liquid outlet through-hole 34 are respectively disposed on both sides of the adsorption rod 32. Further, the adsorption rod 32 is a magnetic rod.

[0060] There are multiple adsorption rods 32, and the multiple adsorption rods 32 are arranged in an array in the adsorption cavity 33 to form an adsorption unit group; wherein, the second open end 35 and the liquid outlet through-hole 34 are respectively disposed on opposite sides of the adsorption unit group. Specifically, the second open end 35 is used to receive the wastewater flowing out of the honeycomb filter bin 20; when the wastewater passes through the magnetic rod, the salts, heavy metals and magnetic impurities therein are adsorbed by the adsorption rod 32; subsequently, the purified wastewater is discharged from the liquid outlet through-hole 34.

[0061] The adsorption rod 32 is a magnetic rod. As the core component of the adsorption bin 30, the magnetic rod not only has a strong adsorption capacity, but also can promote the rapid aggregation of magnetic impurities in the wastewater to the surface of the magnetic rod through the magnetic field effect, thereby improving the desalination efficiency.

[0062] The second open end 35 and the liquid outlet through-hole 34 are respectively disposed on both sides of the adsorption rod 32, so that the wastewater must flow through the magnetic rod, enabling the wastewater to fully contact and be affected by the magnetic field, thereby improving the adsorption efficiency of salts and metal impurities.

[0063] According to some embodiments of the present application, with reference to Figure 1 and Figure 5 , the housing 31 includes a body 311 and a cover plate 312. The adsorption rod 32 is disposed on the cover plate 312, and the side of the cover plate 312 having the adsorption rod 32 is detachably disposed on the body 311.

[0064] The housing 31 includes the main body 311 and the cover plate 312. The main body 311 is the main structural part of the adsorption bin 30. The inside of the main body 311 has the adsorption cavity 33 and is used to accommodate the adsorption rod 32. The cover plate 312 covers the upper part of the main body 311, and the cover plate 312 and the main body 311 are fixed by snap fasteners or the like. The cover plate 312 is detachably connected to the adsorption rod 32. When it is necessary to replace or maintain the adsorption rod 32, the cover plate 312 is opened to take out or install a new adsorption rod 32.

[0065] By dividing the housing 31 into the main body 311 and the detachable cover plate 312, it becomes simpler and faster to replace and maintain the adsorption rod 32. This reduces the maintenance cost and improves the use efficiency of the device.

[0066] According to some embodiments of the present application, referring to Figure 1 , the mud hopper bin 10, the honeycomb filter bin 20, and the adsorption bin 30 are integrally formed.

[0067] The mud hopper bin 10, the honeycomb filter bin 20, and the adsorption bin 30 are integrally formed into a whole by injection molding, casting, or other appropriate manufacturing processes. Specifically, the mud hopper bin 10 is located at the bottom and has the mud hopper cavity 11. The honeycomb filter bin 20 is directly arranged above the mud hopper bin 10 and internally contains a plurality of inclined honeycomb channels 22. One end of the honeycomb channel 22 is connected to the first open end 12. The adsorption bin 30 is located above the honeycomb filter bin 20. The adsorption bin 30 is provided with a liquid outlet through hole 34 and a second open end 35, and the second open end 35 is connected to the other end of the honeycomb channel 22.

[0068] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered within the scope of the claims and the description of the present application.
