Description

Technical Field

[0001] The utility model relates to an aquarium filtering technology, in particular to a filter material for improving the denitrification effect. Background Art

[0002] In aquarium breeding, there are a lot of impurities such as feces, body fluids, and food residues in the water of aquariums. These impurities will produce a lot of organic matter, ammonia nitrogen, nitrites, and nitrates. The high nitrogen content affects the water quality. When the concentration of the above substances is too high, algae and yellow-green floating objects will be produced in the water, which will weaken the activity of aquatic organisms and even cause death. In order to solve the above phenomenon and ensure the water quality in the aquarium, a filter composed of a water pump and a filter box with filter materials is currently arranged in the aquarium to remove the above impurities. The microorganisms such as ammonia oxidizing bacteria stored on the biochemical filter material arranged in the filter box decompose ammonia nitrogen, nitrites, and nitrates to achieve the purpose of denitrification and remove organic matter in the water to keep the water clear. At present, most of the biochemical filter materials are biochemical cotton, ceramic rings or coral stones with more holes. The holes increase the specific surface area of ​​these biochemical filter materials so that as many microorganisms as possible can be stored on these biochemical filter materials for growth and reproduction. However, for water bodies containing dirt impurities and ammonia nitrogen, nitrite and nitrate, if the decomposition efficiency and denitrification effect of ammonia nitrogen, nitrite and nitrate in the water are to be guaranteed, the amount of biochemical filter materials can only be increased to increase the number of microorganisms, which increases the volume of the filter and affects the layout of the aquarium and the beauty of the entire aquarium. In addition, in order to maintain the long-term stable number of microorganisms to ensure the decomposition efficiency and denitrification effect, it is necessary to maintain sufficient and continuous supply of the nutrient carbon source required for the growth and reproduction of microorganisms. However, the current biochemical filter materials are only used as storage places for microorganisms, and the nutrient carbon source required for the growth and reproduction of microorganisms needs to be supplemented separately, which is very inconvenient and not conducive to the growth and reproduction of microorganisms, affecting the purification of water quality in the aquarium. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a filter material which can provide sufficient storage space for the growth and reproduction of microorganisms and can provide sufficient and continuous stable supply for the growth and reproduction of microorganisms and improve the denitrification effect.

[0019] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that, in the accompanying drawings, the same reference numerals are given to components having substantially the same structure and function, and in order to make the description more concise, redundant descriptions of substantially the same components are omitted.

[0020] like Figure 1-5 As shown, a filter material for improving denitrification effect includes a filter material shell 1 made of a degradable plastic as a carbon source, a placement space 2 is provided in the filter material shell 1, a filter material inner core 3 is provided in the placement space 2, a bacteria breeding storage area is distributed on the filter material inner core 3, and a channel 5 connected to the placement space 2 is distributed on the filter material shell 1. The filter material inner core 3 is a columnar inner core made of ceramic filter material, and the bacteria breeding storage area is the pores 4 that are interconnected on the filter material inner core 3. The columnar inner core can be made of ceramic filter material by foaming process, and the filter material inner core 3 is embedded and installed in the placement space 2 set inside the filter material shell 1, and the filter material shell 1 wraps the filter material inner core 3 in an integral form. These mutually interpenetrating pores 4 on the filter material inner core 3 can be used as a microbial breeding storage place to achieve a high degree of denitrification cycle in the aquarium, reduce nitrate accumulation, keep the water quality in the aquarium clear, and reduce the user's water change frequency.

[0021] like Figure 1As shown, the filter material shell 1 is spherical, and forms a hollow sphere with the distributed channels 5. When in use, water can flow smoothly through and increase the specific surface area of ​​the filter material shell 1; the filter material shell 1 can also be in other shapes such as triangular, cubic, cylindrical or elliptical, but the spherical filter material shell 1 is convenient for filling the filter material in the filter box, and can increase the filling quantity of the filter material in the filter box of the same volume. It is beneficial to reduce the volume of the filter while ensuring the area of ​​the microbial reproduction and storage place, which is convenient for layout in the aquarium and improves the overall aesthetics of the aquarium. The filter material shell 1 is composed of two shells 6 that are buckled together, which is convenient for the disassembly and assembly of the filter material shell 1 and the installation of the filter material inner core 3.

[0022] like Figure 1-4 As shown, the sub-shell 6 includes a plurality of grid plates 7 that are spaced apart and arranged in parallel, and arc-shaped connecting plates 8 are respectively arranged at both ends of the grid plates 7, and the inner sides of the two connecting plates 8 are respectively connected to the two ends of each grid plate 7, and the connecting plates 8 corresponding to each other on the two sub-shells 6 are buckled and connected, so that the pores 4 between the grid plates 7 on the filter material shell 1 form the channels 5 distributed on the filter material shell 1, and the entire filter material shell 1 and the channels 5 constitute a three-dimensional multi-faceted structure, which greatly increases its specific surface area and improves the overall utilization rate. At the same time, the water flow can smoothly pass through the pores 4 between the grid plates 7 and then flow into the filter material core 3. The grid plates 7 and the connecting plates 8 on each of the sub-shells 6 are made of degradable plastics in one piece, which is convenient to manufacture. Each of the grid plates 7 is semi-annular, and the filter material core 3 is located in the placement space 2 surrounded by each semi-annular grid plate 7, so that the filter material core 3 directly faces the pores 4 between the grid plates 7, which is conducive to the passage of water. The buckling part of one of the sub-shells 6 is provided with a plurality of plug-in posts 9, and the buckling part of the other sub-shell 6 is provided with a plug-in hole 10 corresponding to the plug-in posts 9, so that the two sub-shells 6 can be conveniently connected and buckled. A separation base groove 11 is provided along the buckling part between the two sub-shells 6 to facilitate the disassembly and assembly of the two sub-shells 6. The separation base groove 11 can be provided with mutually matching stepped surfaces 12 on the buckling surfaces of two corresponding buckling connecting plates 8, wherein the stepped surface 12 on one connecting plate 8 faces outward and the stepped surface 12 extends along the outer side surface of the connecting plate 8 to form the separation base groove 11.

[0023] like Figure 1As shown, the filter material shell 1 is made of a degradable plastic as a carbon source. The degradable plastic can be made of polylactic acid PLA, poly 3-hydroxyalkanoate PHA or starch. It is a well-known technology to use degradable plastic as a carbon source for microorganisms, which will not be described in detail here. The filter material shell 1 made of degradable plastic is constantly consumed and decomposed by microorganisms such as ammonia oxidizing bacteria due to its biodegradable characteristics during use. The microorganisms can achieve denitrification in the aquarium, and ammonia nitrogen, nitrite and nitrate are decomposed. At the same time, the filter material inner core 3 has a large number of through pores 4, which can be used as a breeding and storage place for microorganisms, realizing a high degree of complete denitrification cycle in the aquarium, reducing nitrate accumulation, and reducing the user's water change frequency. This filter material can also be used in freshwater and seawater environments. During use, the filter material shell 1 will be gradually consumed and is suitable for being placed in a low-oxygen position in the aquarium filtration system to maximize its energy efficiency.
