Description

Sink mud bionic coral and manufacturing method thereof

The present invention relates to a bionic coral, in particular to a mud bionic coral used for water quality adjustment, aquarium landscaping, and ecological restoration.

Coral is a general term for coral polyps and their exoskeleton. They mainly grow in tropical oceans. They are commonly found in symbiosis with algae. They are habitats for many animals and microorganisms, and have the function of regulating water quality. Xizhi will use dead coral or coral exoskeleton as live rock for the aquatic ecosystem. In addition, other porous calcium carbonate rocks or bionic corals are also used as live rocks. The porosity, calcium carbonate, and bacteria contained in live rocks or bionic corals all contribute to the adjustment of water quality and provide a better aquatic environment.

On the other hand, Taiwan has a subtropical climate with abundant rainfall, but the water shortage is caused by the accumulation of reservoirs. The silt of the reservoir seriously affects the function of the reservoir. In addition to the removal of silt from the reservoir, there are also issues such as silt treatment and utilization. In addition, there are landscape pollution caused by the dumping and accumulation of oyster shells along the coast of Taiwan. Therefore, we think about how to integrate these environmental wastes and turn them into beneficial items. Considering the high permeability of reservoir silt and the rich calcium carbonate contained in oyster shells, it will be one of our demands to reproduce these two characteristics on new products.

The invention provides a bionic coral, which can be used as a biological habitat, used for cultivating flora, and is helpful for ecological restoration.

The invention provides a bionic coral, which can be used to adjust water quality and help establish an aquatic ecosystem.

The present invention provides a method for manufacturing bionic corals, which uses waste materials to help improve the environment and reduce pollution sources.

The present invention also provides an artificial live rock and a manufacturing method thereof. The artificial live rock can be used as a biological habitat and used to adjust water quality. The manufacturing method uses waste materials to help improve the environment and reduce pollution sources.

The other objectives and advantages of the present invention can be further understood from the technical features disclosed in the present invention.

The biomimetic coral provided by the present invention comprises a mixture of reservoir silt and calcium carbonate substrate and roasted, wherein the ratio of reservoir silt and calcium carbonate substrate is between 9:1 and 6:4, and the calcium carbonate substrate is ground and burned from oyster shells. Made.

In order to achieve one or part or all of the above objectives or other objectives, the present invention also provides a method for manufacturing biomimetic corals, including the following steps: providing reservoir silt and oyster shells; grinding and roasting the oyster shells to form a calcium carbonate matrix; mixing; The reservoir silt and the calcium carbonate matrix are mixed to form a mixture, wherein the reservoir sludge and the calcium carbonate matrix are mixed in a ratio between 9:1 and 6:4; the mixture is shaped so that the mixture has a shape; and the mixture is roasted.

The invention adopts reservoir silt, so it has porosity, which is helpful for the cultivation of flora; because the ratio of reservoir silt to calcium carbonate substrate is between 9:1 and 6:4, it has water permeability and has the function of water quality adjustment. , It can adjust the nitrate and nitrite content of the water body, as well as the pH value and water hardness. Because the calcium carbonate substrate comes from oyster shells and the silt of the reservoir is also a waste material, the present invention also helps to improve the environment and reduce pollution sources.

In order to make the above and other objects, features and advantages of the present invention more comprehensible, the following specific examples are given in conjunction with the accompanying drawings, which are described in detail as follows.

The bionic coral of the present invention includes a reservoir silt and a calcium carbonate substrate. More specifically, it is a reservoir mud bionic coral formed by mixing and roasting reservoir silt (ie, reservoir mud) and a calcium carbonate substrate, and the calcium carbonate substrate is taken from oysters. shell. Calcium carbonate is the main component of oyster shells. In an embodiment of the present invention, the silt is the silt of Shimen Reservoir, and oyster shells are collected from wetlands such as Xiangshan Wetland, but it is not limited to this. After crushing and grinding the collected oyster shells, they are roasted in a kiln to obtain the aforementioned calcium carbonate matrix. After grinding and/or sieving the calcium carbonate matrix, a finer powder can be obtained. Reservoir silt can provide bionic coral with better porosity and better water permeability, and together with calcium carbonate matrix, it can give artificial live rocks the function of adjusting water quality. Based on the reservoir silt and calcium carbonate matrix, the reservoir mud bionic coral of the present invention may have a composition similar to or equivalent to the naturally occurring coral exoskeleton.

Reservoir silt and calcium carbonate matrix can be mixed in a weight ratio of, for example, 9:1, 8:2, 7:3, or 6:4. If the amount of calcium carbonate substrate is too small, the effect of the mud bionic coral may not be significant; if the amount of calcium carbonate substrate is too large, the structure of the mud bionic coral may be poor (detailed later). The ratio of reservoir silt to calcium carbonate substrate is preferably 8:2 or 7:3.

The temperature for roasting the reservoir sludge and calcium carbonate matrix mixture can be, for example, between 1100°C and 1200°C. If the roasting temperature is too low or too high, it may affect the hardness and water permeability of the mud bionic coral (detailed later). When the mud bionic coral is used in the aquarium ecosystem and/or to adjust the water quality, improper hardness and water permeability may affect its efficacy. In a preferred embodiment of the present invention, the firing temperature is 1150°C.

The reservoir mud bionic coral of the present invention may further include biological substances, that is, the reservoir mud bionic coral is made by mixing and roasting reservoir silt, calcium carbonate substrate and biological substances. In an embodiment of the present invention, the biomass is a plant biomass, such as herbaceous plant biomass, rice husk and wood chips, but not limited to this. The addition of biomass can increase the number of biomimetic coral pores in the reservoir mud, increase its surface area, thereby increasing the area where organisms can inhabit, and also help improve the efficiency of water quality adjustment.

In an embodiment of the present invention, the mud bionic coral further includes a surface layer, and the surface layer is formed by firing glaze. Furthermore, a mixture of reservoir silt and calcium carbonate substrate or a mixture of reservoir silt, calcium carbonate substrate and biomass forms the main body of the reservoir mud bionic coral, and the main body is distributed with glaze and roasted together. The glaze is formulated in a conventional manner and can include a variety of mineral powders and metal oxides and other raw materials. For example, the ratio of the raw materials can be determined according to the roasting temperature and the color to be displayed on the surface of the mud bionic coral; the thickness of the distributed glaze can affect the thickness of the surface layer. The calcium carbonate in the glaze also helps to adjust the water quality, and the colorful mud bionic coral can enrich the visual experience of the aquatic ecosystem.

The invention also provides a method for manufacturing the mud bionic coral. In one embodiment, as shown in FIG. 1, the manufacturing method includes step S110: providing reservoir silt and oyster shells, and step S120: grinding and roasting the oyster shells to form a calcium carbonate matrix. The reservoir sludge in step S110 can be further processed or processed. Generally speaking, its impurities are filtered and excess water is removed. In step S120, the calcium carbonate matrix is generally in the form of powder, and can be ground and/or sieved to obtain fine calcium carbonate powder, as shown in FIG. 2.

After step S110 and step S120, step S130 can be performed: mixing the reservoir sludge and the calcium carbonate matrix to form a mixture, wherein the reservoir sludge and the calcium carbonate matrix are mixed in a ratio between 9:1 and 6:4. Step S130 may also include measuring the calcium carbonate matrix in the proportion, dissolving the calcium carbonate matrix in water to form a solution, pouring the solution into the reservoir sludge and mixing uniformly, and making the mixture have proper moisture and softness for example Follow-up shaping. Preferably, the ratio of reservoir silt to calcium carbonate substrate is 8:2 or 7:3. The biomimetic coral made from mud in a ratio of 8:2 or 7:3 has been tested and can effectively improve the nitrate and nitrite content of the water body, as well as the acid-base value (pH value) and water hardness (GH value, KH value), and the structure is better, avoiding the situation of easy collapse and chipping. The test method of water quality will be described in the experimental example.

Step S130 may further include adding biomass and mixing with reservoir silt and calcium carbonate matrix. In an embodiment of the present invention, herbaceous plant biomass such as rice husks and wood chips are used, wherein the rice husks are obtained from farmers' associations or rice mills, and the wood chips can be obtained from wood factories. Biomass helps to increase the number of pores and surface area of the biomimetic coral in the mud, as shown in Figure 3 (the dotted line in the upper left is the magnification of the red dot).

After step S130, step S140 can be performed: shaping the mixture so that the mixture has a shape. The mixture can be individually shaped by hand, such as designing a mold, pouring and shaping, or introducing any shaping method according to the desired shape. Preferably, step S130 is to shape the mixture according to the natural coral shape, structure or stone shape, and the shape can be further adjusted in detail. When the mud bionic corals are used in aquatic ecosystems and/or ecological restoration, the coral or stone shape can help present the natural ecological landscape, but it is not limited to this. As the mixture may shrink and expand during subsequent roasting, thick and full shapes such as clump coral shape, brain coral shape, ammonite coral shape, and reef coral shape can be used to reduce the shrinkage and expansion of the mud bionic coral. The opportunity for expansion and destruction is not limited by this.

Step S140 may further include forming a recess on the shape, or other methods of reserving space. During firing, the concave portion or space can be used as a buffer space for expansion or contraction of the shape. Considering that it does not affect the appearance of the mud bionic coral, the recess can be set at the bottom of the shape. Furthermore, based on the roasting process that will cause the mixture to shrink, step S140 preferably includes relatively enlarging the volume of the modeling according to the size of the mud bionic coral to be formed. In one embodiment, for example, the shape of the mixture can be 1.25 times larger than that of the mud bionic coral. If the roasting process reduces the volume of the mixture by 20%, a sump mud bionic coral of just the size can be obtained.

After step S140, the mixture can be further dried, and then step S150: roasting the mixture. In detail, in step S150, the mixture with the shape is put into a kiln and fired at a temperature between, for example, 1100°C and 1200°C. After testing, the mud bionic corals fired in this temperature range, as shown in Figure 4A~4C, 4B, have no excessive dust on the surface, moderate hardness, and better water permeability. In contrast, as shown in Figure 4A, the silo mud bionic coral burned at a lower temperature has more dust on the surface, which is easy to disintegrate, and has lower hardness; as shown in Figure 4C, the silo mud bionic coral fired at a higher temperature The surface of the coral is smoother, the hardness is higher, and the water permeability is poor. In a preferred embodiment of the present invention, it is calcined at 1150°C for 7-8 hours. Step S150 may further include removing dust on the surface of the mud bionic coral after roasting. The obtained reservoir mud bionic coral can be directly put into the water to adjust the water quality, and can be used for biological habitat, cultivating flora, landscaping, and/or ecological restoration.

In another embodiment, as shown in FIG. 5, the manufacturing method of the present invention further includes step S160: providing glaze and distributing the glaze on the surface of the shape. Step S160 is preferably performed between steps S140 and S150. The glaze is formulated in a conventional manner, and can contain a variety of mineral powders and metal oxides and other raw materials, which can be formulated according to the aforementioned temperature range of 1100°C to 1200°C and the color to be displayed on the surface of the kumu bionic coral. Including but not limited to dipping, spraying, brushing, showering, painting, etc., glaze is distributed on the shape so that the surface of the shape has a glaze layer.

Preferably, step S160 further includes drying the mixture to distribute the glaze on the dry surface of the model. As shown in Figure 6, the surface of the shape gradually appears off-white when dried. After the glaze is dispensed, as shown in Figure 7, the surface of the shape shows a preliminary color.

After step S160, the glaze layer can be further dried, and then step S150 is performed. Comparing the kumu bionic coral made without firing in step S160 and the kumu bionic coral fired in step S160, as shown in Figure 4B and Figure 8, the color of the former is generally warm colors such as orange, orange, coffee, etc. , The latter has a surface layer, and the surface layer can have colors other than warm colors.

The present invention further tests the effect of the reservoir mud bionic coral made by the aforementioned method on water quality adjustment, which is described in the experimental example.

Experimental example: The effect of Kumu bionic coral on water quality adjustment

The purpose of the experiment: to evaluate the effectiveness of the reservoir mud bionic coral in water quality adjustment from items such as nitrate content, nitrite content, acid-base value (pH value), general water hardness (GH value) and carbonate hardness (KH value).

Experimental materials: Kumu bionic coral, commercially available ceramic ring, API five-in-one test piece, water (in a water tank).

experimental method: 1. Prepare at least two tanks of water, and test the nitrate content, nitrite content, pH value, GH value and KH value of the two tanks of water with the API five-in-one test piece. 2. Place the reservoir mud bionic coral and commercially available ceramic rings in different tanks, and start from the same day (day 1), use the API 5-in-1 test piece to test the nitrate content and nitrite content of the two tanks of water for seven consecutive days. Salt content, pH value, GH value and KH value.

Experimental results: 1. Figure 9 shows the influence of the mud bionic coral on the nitrate content in the water. The excretion of aquatic organisms such as fish and the growth of organic matter will increase the concentration of nitrates, resulting in poor water quality, and thus the death of fish. As shown in Figure 9, the efficiency of the mud biomimetic coral in reducing nitrate content is better than that of commercially available ceramic rings. 2. Figure 10 shows the impact of the mud bionic coral on the nitrite content in the water. Nitrite will hinder the fish's breathing, and when the content is high, it will quickly cause the fish to die. Even a small amount will cause the fish to be stressed and hinder the development of the immune system. As shown in Figure 10, the mud bionic coral has the effect of reducing the nitrite content. 3. Figure 11 shows the impact of the mud bionic coral on the pH of the water. Generally speaking, pH 6.8~7.2 is the most suitable environment for fish to live. As shown in Figure 11, compared to the commercially available ceramic rings, the mud bionic coral can maintain the water at a better pH of 6.8~7.2. 4. Figure 12 shows the impact of reservoir mud bionic coral on the KH value of water. KH is carbonate hardness, which can reflect the content of carbonate and bicarbonate in water. The KH value can affect the growth of aquatic plants. The present invention takes KH value=40 as the desired value. As shown in Figure 12, compared to the commercially available ceramic rings, the Kumu bionic coral can adjust the water body to a better KH value of 40 faster. 5. Figure 13 shows the impact of reservoir mud bionic coral on the GH value of water. GH is the general hardness, which can reflect the content of calcium ions and magnesium ions in the water. GH value=6~16 is a better growth environment for most freshwater fish. As shown in Figure 13, the mud bionic coral can adjust the GH value of the water body to 180ppm, which is equivalent to about 10°dH (1°dH = 17.6ppm), which is suitable for fish growth.

The pool mud bionic coral of the present invention and the pool mud bionic coral prepared by the method of the present invention have porosity and water permeability, and are suitable for cultivating flora such as nitrifying bacteria flora. Bacteria can not only live naturally in the mud bionic corals, but also artificially cultivate the flora and algae on the mud bionic corals to establish an ecosystem of the mud bionic corals and use them in natural waters such as the ocean or man-made Waters are like aquariums.

The invention also provides an artificial live rock. The artificial live rock includes a reservoir silt and a calcium carbonate matrix. Further, it is formed by mixing and roasting the reservoir silt and calcium carbonate matrix in a weight ratio between 9:1 and 6:4, and the calcium carbonate matrix is taken from Oyster shell. The artificial live rock can be manufactured as described above for the method of manufacturing biomimetic coral in the mud, and can be used for water quality adjustment, as a biological habitat, cultivating flora, landscaping, and/or ecological restoration.
