Description

Technical Field

[0001] This invention relates to the field of dredged sediment treatment technology, and more specifically, to a culture medium packing material. Background Technology

[0002] Dredged sediment is typically large in volume and complex in composition, containing a large amount of harmful substances such as pathogens, viruses, parasites, heavy metals, and organic pollutants. Due to these characteristics, a simple dewatering-land application method is not feasible. Therefore, a treatment method that can fully utilize the organic matter, nitrogen, phosphorus, and other nutrients in the sediment is needed.

[0003] Aerobic fermentation technology is a comprehensive sludge treatment technology that achieves harmlessness, volume reduction, and stabilization. It utilizes aerobic microorganisms to decompose organic matter under aerobic conditions, while simultaneously killing pathogens and parasite eggs at high temperatures, thereby improving sludge fertility. This technology not only achieves sludge volume reduction and harmless treatment but also enables its resource utilization.

[0004] In recent years, membrane-covered high-temperature aerobic fermentation technology has been developed as a novel sludge treatment technology. This technology utilizes a specially designed microporous functional membrane to cover the fermentation pile, and creates a micro-high pressure state through air blowing, ensuring uniform oxygen supply and temperature distribution, thereby promoting the full degradation of organic matter and temperature sterilization.

[0005] Due to significant differences in the physicochemical composition of the sediment, the high specific gravity and relatively low organic matter content of simple sediment make fermentation difficult and compromise its effectiveness. Furthermore, existing fermentation additives have low strength and are easily crushed into flakes. Combined with the high viscosity and compaction of dehydrated sediment, this leads to anaerobic fermentation in the fermentation pile, hindering the growth of aerobic microorganisms and affecting the aerobic fermentation effect. However, using round materials makes them easily turned to the surface during turning; flake materials cannot create voids within the sediment, preventing aerobic fermentation and resulting in low efficiency in dredged sediment treatment.

[0006] As can be seen from the above, the existing technology has the problem of low efficiency in treating dredged sediment. Summary of the Invention

[0007] The main objective of this invention is to provide a culture medium packing material to solve the problem of low efficiency in the treatment of dredged sediment in the prior art.

[0008] To achieve the above objectives, according to one aspect of the present invention, a culture medium packing material is provided, comprising a first plate and a second plate, wherein the first plate and the second plate are respectively processed from the same substrate to be processed, the substrate to be processed is an axisymmetric polygon, and the lower part of the substrate to be processed is a pointed portion, the first plate has a first mounting notch extending downward from the top, and the second plate has a second mounting notch extending upward from the bottom, wherein the first plate and the second plate are engaged through the first mounting notch and the second mounting notch.

[0009] Furthermore, the culture medium packing also includes a fixing plate, which is an axisymmetric polygon. The fixing plate has a third mounting notch extending outward from the inner end, and the fixing plate is engaged with the first plate or the second plate through the third mounting notch.

[0010] Furthermore, there are two fixing plates, which are respectively engaged with the two sides of the first plate or the two sides of the second plate.

[0011] Furthermore, the first mounting notch is located on the central axis of the first plate; and / or the second mounting notch is located on the central axis of the second plate; and / or the third mounting notch is located on the central axis of the fixing plate.

[0012] Furthermore, the fixing plate is perpendicular to the first plate and the second plate; and / or the first plate is perpendicular to the second plate.

[0013] Furthermore, the length L1 of the first plate is greater than the length L2 of the second plate.

[0014] Furthermore, the substrate to be processed is an axisymmetric hexagon, with the length L1 of the first plate being 9.4cm to 11.4cm and the length L2 of the second plate being 8.7cm to 10.7cm.

[0015] Furthermore, the substrate to be processed is an axisymmetric hexagon, with a width D1 of 4.2cm to 6.2cm; a base angle α1 of 40° to 50°; upper left and right angles α3 of 115° to 125°; lower left and right angles α4 of 152° to 162°; the width d1 of the first mounting notch is the same as the width d2 of the second mounting notch, both being 0.7cm to 0.9cm; the depth H1 of the first mounting notch is 2.45cm to 2.85cm; and the depth H2 of the second mounting notch is 5.8cm to 7.8cm.

[0016] Furthermore, the fixing plate is an axisymmetric pentagon, and the width D2 of the fixing plate is the same as the width D1 of the substrate to be processed, both being 4.2cm to 6.2cm; the upper and lower left corners β1 of the fixing plate are 115° to 125°; the upper and lower right corners β2 of the fixing plate are 90°; the width d3 of the third mounting notch, the width d1 of the first mounting notch, and the width d2 of the second mounting notch are all the same, both being 0.7cm to 0.9cm; the depth H3 of the third mounting notch is 2cm to 2.4cm.

[0017] Furthermore, the distance from the side of the first plate to the end face of the second plate on the same side, or the distance from the side of the second plate to the end face of the first plate on the same side, is the same as the depth H3 of the third mounting notch.

[0018] Furthermore, the thickness of the substrate to be processed, the width d1 of the first mounting notch, and the width d2 of the second mounting notch are all the same.

[0019] Furthermore, the thickness of the substrate to be processed is the same as the width d3 of the third mounting notch.

[0020] Furthermore, the culture medium filler is made of pine wood.

[0021] The technical solution of this invention provides a culture medium filler comprising a first plate and a second plate, both formed from the same substrate. The substrate is an axially symmetrical polygon with a pointed tip at the bottom. The first plate has a first mounting notch extending downward from the top, and the second plate has a second mounting notch extending upward from the bottom. The first and second plates are engaged through the first and second mounting notches, forming a tenon-and-mortise structure that improves the structural strength of the culture medium filler. This ensures a certain amount of space within the dredged sediment, allowing for smooth aerobic fermentation. The tip of the culture medium filler can be effectively inserted into the dredged sediment, preventing it from being turned to the surface during turning and thus ensuring the treatment efficiency of the dredged sediment. This solves the problem of low treatment efficiency of dredged sediment in the prior art. Attached Figure Description

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0034] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0035] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0036] To address the problem of low efficiency in treating dredged sediment in existing technologies, this invention provides a culture medium packing material.

[0037] like Figures 1 to 3 , Figure 5 As shown, the culture medium packing includes a first plate 10 and a second plate 20. The first plate 10 and the second plate 20 are respectively processed from the same substrate 100. The substrate 100 is an axisymmetric polygon, and the lower part of the substrate 100 is a pointed portion. The first plate 10 has a first mounting notch 11 extending downward from the top, and the second plate 20 has a second mounting notch 21 extending upward from the bottom. The first plate 10 and the second plate 20 are engaged through the first mounting notch 11 and the second mounting notch 21.

[0038] This application uses the interlocking of two plates to form a mortise and tenon structure, thereby improving the structural strength of the culture medium filler and ensuring that a certain gap is maintained inside the dredged sediment, so that aerobic fermentation can proceed smoothly inside the sediment. The tip of the culture medium filler can be effectively inserted into the dredged sediment, preventing it from being turned to the surface during the turning process, thus ensuring the treatment efficiency of the dredged sediment.

[0039] It is understood that the first plate 10 and the second plate 20 of this application are made by machining the first mounting notch 11 and the second mounting notch 21 on the two substrates 100 to be processed, respectively. Since the first mounting notch 11 and the second mounting notch 21 are located at the upper and lower parts of the substrates 100 to be processed, respectively, the first plate 10 and the second plate 20 have most of the same shape, only differing in the position of the notch.

[0040] Furthermore, since the lower part of the substrate 100 to be processed is a pointed part, the processed first plate 10 and second plate 20, after being fitted together to form a culture medium filler, have a conical structure at their lower part, which can be effectively inserted into the dredged bottom mud.

[0041] In this embodiment, the first mounting notch 11 is located on the central axis of the first plate 10. Similarly, the second mounting notch 21 is located on the central axis of the second plate 20. That is, after the first mounting notch 11 and the second mounting notch 21 are respectively formed, the first plate 10 and the second plate 20 still have an axisymmetric structure. Specifically, Figures 2 to 3 and Figure 5 The image shows the orientation of the culture medium packing material in normal use in this embodiment, i.e., both the first plate 10 and the second plate 20 are vertically arranged, the first mounting notch 11 is located at the upper part of the first plate 10 and extends vertically, and the second mounting notch 21 is located at the lower part of the second plate 20 and extends vertically, so that the second plate 20 is inserted into the first mounting notch 11 of the first plate 10 from top to bottom through the second mounting notch 21.

[0042] In this embodiment, as Figures 2 to 3 As shown, the width d1 of the first mounting notch 11 is the same as the width d2 of the second mounting notch 21, and both are the same as the thickness of the substrate 100 to be processed, that is, the same as the thickness of the first plate 10 and the second plate 20. This allows the first plate 10 and the second plate 20 to fit precisely into the second mounting notch 21 and the first mounting notch 11, improving the structural strength of the culture medium filler.

[0043] In this embodiment, the first plate 10 and the second plate 20 are perpendicular. That is, from a top or bottom view, the culture medium packing in this embodiment has a cross-shaped structure.

[0044] In this embodiment, the substrate 100 to be processed is an axisymmetric hexagon, that is, the first plate 10 and the second plate 20 are axisymmetric hexagons. Specifically, the upper part of the substrate 100 to be processed is also a pointed part.

[0045] In this embodiment, as Figures 1 to 3 As shown, the width D1, bottom corner α1, top corner α2, upper left and right corners α3, and lower left and right corners α4 of the substrate 100 to be processed are the same as those of the first plate 10 and the second plate 20, except that the lengths are different because the upper and lower parts are cut into the first mounting notch 11 and the second mounting notch 21, respectively. It should be noted that since the substrate 100 to be processed has an axisymmetric structure with respect to the vertical central axis, its upper left and upper right corners are the same, both being α3, and its lower left and lower right corners are also the same, both being α4.

[0046] In this embodiment, as Figures 1 to 3 As shown, since a pointed portion is required, the bottom angle α1 of the substrate 100 to be processed is smaller than the top angle α2. Correspondingly, the lower left and right corners α4 of the substrate 100 to be processed will be larger than the upper left and right corners α3. Furthermore, based on this, when cutting the second mounting notch 21, more length will be removed than the first mounting notch 11. Therefore, the length L1 of the first plate 10 is greater than the length L2 of the second plate 20. Specifically, the length L1 of the first plate 10 is 9.4 cm to 11.4 cm, preferably 10.4 cm. The length L2 of the second plate 20 is 8.7 cm to 10.7 cm, preferably 9.7 cm.

[0047] In this embodiment, the width D1 of the substrate 100 to be processed is 4.2cm to 6.2cm, preferably 5.2cm.

[0048] In this embodiment, the bottom angle α1 of the substrate 100 to be processed is 40° to 50°, preferably 45°.

[0049] In this embodiment, the apex angle α2 of the substrate 100 to be processed is 115° to 125°, preferably 120°.

[0050] In this embodiment, the upper left and right corners α3 of the substrate 100 to be processed are 115° to 125°, preferably 120°.

[0051] In this embodiment, the lower left and right corners α4 of the substrate 100 to be processed are 152° to 162°, preferably 157°.

[0052] In this embodiment, the width d1 of the first mounting notch 11 and the width d2 of the second mounting notch 21 are both 0.7cm to 0.9cm, preferably 0.8cm.

[0053] In this embodiment, the depth H1 of the first mounting notch 11 is 2.45cm to 2.85cm, preferably 2.65cm.

[0054] In this embodiment, the depth H2 of the second mounting notch 21 is 5.8cm to 7.8cm, preferably 6.8cm.

[0055] like Figures 4 to 5 As shown, the culture medium packing also includes a fixing plate 30. The fixing plate 30 is an axisymmetric polygon, and has a third mounting notch 31 extending outward from its inner end. The fixing plate 30 engages with the first plate 10 or the second plate 20 through the third mounting notch 31. Specifically, the fixing plate 30 is horizontally positioned, with the side of the fixing plate 30 facing the first plate 10 or the second plate 20 being the inner side. The aforementioned inner and outer directions are relative to the central axis of the culture medium packing. By providing the fixing plate 30, the overall structural strength of the culture medium packing can be further improved.

[0056] In this embodiment, there are two fixing plates 30, which are respectively engaged with the two sides of the first plate 10 or the two sides of the second plate 20. It can be understood that the two fixing plates 30 are symmetrically arranged.

[0057] Specifically, in this embodiment, the fixing plate 30 is an axisymmetric pentagon with straight inner edges for abutting against the first plate 10 or the second plate 20. The top and bottom edges of the fixing plate 30 are also straight, while the outer edges are two beveled edges, i.e., the outer edges are pointed portions. In other words, in this embodiment, the top and bottom left angles β2 of the fixing plate 30 are 90°. It should be noted that, since the fixing plate 30 is an axisymmetric structure relative to the horizontal central axis, its top left and bottom right angles are both β2, and its top right and bottom right angles are both β1. Furthermore, the two sides of the substrate 100 to be processed are vertical edges, and the two fixing plates 30 are respectively fitted into the straight sides of the first plate 10 or the second plate 20.

[0058] In this embodiment, the third mounting notch 31 is located on the central axis of the fixing plate 30. That is, when the fixing plate 30 is snapped into the first plate 10 or the second plate 20, it is symmetrical about the first plate 10 or the second plate 20.

[0059] In this embodiment, the fixing plate 30 is perpendicular to the first plate 10 and the second plate 20. That is, the first plate 10, the second plate 20 and the fixing plate 30 are located in the X, Y and Z axes of the Cartesian coordinate system, respectively.

[0060] In this embodiment, as Figure 4 As shown, the width d3 of the third mounting notch 31, the width d1 of the first mounting notch 11, and the width d2 of the second mounting notch 21 are all the same. That is, the thickness of the substrate 100 to be processed, i.e., the thickness of the first plate 10 and the second plate 20, is the same as the width d3 of the third mounting notch 31. This allows the first plate 10 or the second plate 20 to fit snugly into the third mounting notch 31, improving the structural strength of the culture medium filler.

[0061] In this embodiment, as Figure 4 As shown, the width D2 of the fixing plate 30 is the same as the width D1 of the substrate 100 to be processed. In this way, when the fixing plate 30 is engaged with the first plate 10 or the second plate 20, the sides of the two are flush.

[0062] Furthermore, in this embodiment, the distance from the side of the first plate 10 to the end face of the second plate 20 on the same side, or the distance from the side of the second plate 20 to the end face of the first plate 10 on the same side, is the same as the depth H3 of the third mounting notch 31. With the above arrangement, when the fixing plate 30 is engaged with the first plate 10 or the second plate 20, the inner edge of the fixing plate 30 exactly abuts against the side of the first plate 10 or the second plate 20, ensuring the limiting and stopping of the first plate 10 or the second plate 20 and improving structural strength.

[0063] In this embodiment, the upper and lower right corners β1 of the fixing plate 30 are 115° to 125°, preferably 120°.

[0064] In this embodiment, the depth H3 of the third mounting notch 31 is 2cm to 2.4cm, preferably 2.2cm.

[0065] In this embodiment, the culture medium packing material is pine wood. That is, the first plate 10, the second plate 20, and the fixing plate 30 are all made of pine wood. Using pine wood can provide nutrients for microorganisms, and the relatively hard texture of pine wood can provide support for the sediment, preventing anaerobic fermentation inside the sediment and affecting the fermentation effect.

[0066] In one alternative embodiment, such as Figure 6 As shown, the substrate 100 to be processed is an axisymmetric pentagon, that is, the first plate 10 and the second plate 20 are axisymmetric pentagons. Specifically, the top of the substrate 100 to be processed is a horizontal straight edge rather than a pointed part.

[0067] Furthermore, in another alternative embodiment, such as Figure 7 As shown, the substrate 100 to be processed is an axisymmetric rhombic quadrilateral, that is, the first plate 10 and the second plate 20 are axisymmetric rhombic quadrilaterals. Specifically, the top of the substrate 100 to be processed is also a pointed portion.

[0068] This application only provides specific examples of the above-mentioned structural shapes of the substrate 100 to be processed. In fact, the substrate 100 to be processed can also be other shapes, such as an axisymmetric triangle, or a polygon with more than one hexagon, etc., which can be selected according to actual needs.

[0069] In one specific embodiment, the length L of the substrate 100 to be processed is 10.6 cm, the width D1 of the substrate 100 to be processed and the width D2 of the fixing plate 30 are both 5.2 cm, the bottom angle α1 is 45°, the top angle α2 is 120°, the upper left and right angles α3 are 120°, and the lower left and right angles α4 are 157°. The widths d1, d2, and d3 of the first mounting notch 11, the second mounting notch 21, and the third mounting notch 31 are all 0.8 cm. The depth H1 of the first mounting notch 11 is 2.65 cm, the depth H2 of the second mounting notch 21 is 6.8 cm, the length L1 of the first plate 10 is 10.4 cm, and the length L2 of the second plate 20 is 9.7 cm. The upper left and lower right angles β2 of the fixing plate 30 are 90°, the upper right and lower right angles β1 are 120°, the length h1 is 3 cm, the length h2 of the upper and lower sides is 1.5 cm, and the depth H3 of the third mounting notch 31 is 2.2 cm.

[0070] In this embodiment, the preparation of the culture medium packing includes the following steps:

[0071] S1. Pine wood is made into pine boards with a thickness of 0.8cm. Then, two substrates 100 to be processed and two fixing plates 30 are cut out by laser cutting. Then, notch cutting is performed on the two substrates 100 to be processed to make the first plate body 10 and the second plate body 20.

[0072] S2. Assemble the first plate 10 and the second plate 20 through two mounting notches, forming a pointed end at the bottom.

[0073] S3. Fix the two fixing plates 30 from opposite sides, and combine the third mounting notch 31 of the fixing plate 30 with the two sides of the first plate 10 or the second plate 20 to reinforce the entire structure.

[0074] Furthermore, after inoculating the assembled culture medium with aerobic microorganisms, it is mixed with the sediment. Ensure the sediment and culture medium are thoroughly mixed. The culture medium content is 2% (by total weight).

[0075] The fermentation effect of the culture medium filler material of this application was analyzed through experiments. After preparing 1 kg of culture medium filler material according to the above method, 49 kg of dehydrated bottom mud (moisture content ≥60%) from geotextile bags was poured in, and a 1‰ concentration of aerobic bacterial agent was sprayed. A control group was also set up, consisting of 2 kg of pine sawdust, 0.8 cm thick and 10 cm long, with all other conditions unchanged. Fermentation was carried out in small fermentation chambers. After 7 days of fermentation, samples were taken to test the pore size and surface area of ​​the bottom mud particles. The experimental results are shown in the table below:

[0076] Table 1: Comparison of Fermentation Effects of Pine Wood Chips and Culture Medium Filler

[0077]

[0078] Based on the above experimental results, it can be seen that adding the culture medium filler of this application can effectively improve the pore size of the sediment, promote the aerobic decomposition process of microorganisms, fully decompose the sticky organic matter in the sediment, and reduce the sediment particle size.

[0079] The culture medium packing materials according to the shapes described in the three embodiments above were cut on 0.8 cm thick pine boards, keeping their sizes basically uniform. 2 kg of each material was prepared and mixed with 50 kg of dehydrated substrate (moisture content ≥40%). The reason for choosing dehydrated substrate is that the dehydration process compresses the dredged substrate to a compact state, severely affecting the fermentation effect. To obtain the most significant difference in fermentation results, dehydrated substrate is the optimal choice. The effectiveness of different shaped culture medium packing materials was verified by analyzing the effective nutrient elements of the final fermentation product. The experimental results are as follows:

[0080] Table 2: Comparison of Fermentation Effects of Different Shaped Culture Medium Packing Materials

[0081] Experimental subjects Organic matter (g / kg) Available nitrogen (mg / kg) Available phosphorus (mg / kg) Available potassium (mg / kg) Shape 1 80.3 182 16 84 Shape 2 85.5 175 12 78 Shape 3 78.1 203 28 109

[0082] Among them, shape 1 is Figure 6 The shape shown, shape 2 is Figure 7 The shape shown, shape 3 is Figures 1 to 5 The shape shown.

[0083] During aerobic fermentation, the higher the activity of aerobic microorganisms, the more organic matter they consume, and the greater the content of available nitrogen, available phosphorus, and available potassium that can be absorbed and utilized by plants. The results of this experiment demonstrate that Shape 2 is the least effective, and it was also found during the experiment that Shape 2 could not mix well with the sediment, thus failing to provide a good promoting effect. Shape 1 is the next best; although it can mix with the sediment, its ventilation effect is average, and it cannot provide sufficient oxygen for aerobic microorganisms. Shape 3 is the most effective and is therefore the optimal shape for this application.

[0084] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: the culture medium filler includes a first plate 10 and a second plate 20, which are respectively processed from the same substrate 100 to be processed. The substrate 100 to be processed is an axisymmetric polygon, and the lower part of the substrate 100 to be processed is a pointed part. The first plate 10 has a first mounting notch 11 extending downward from the top, and the second plate 20 has a second mounting notch 21 extending upward from the bottom. The first plate 10 and the second plate 20 are engaged through the first mounting notch 11 and the second mounting notch 21. In this way, the engagement of the two plates forms a tenon and mortise structure, thereby improving the structural strength of the culture medium filler and ensuring that a certain gap is maintained inside the dredged sediment, so that aerobic fermentation can be carried out smoothly inside the sediment. The tip of the culture medium filler can be effectively inserted into the dredged sediment, preventing it from being turned to the surface during the turning process, thereby ensuring the treatment efficiency of the dredged sediment.
