Description

Technical Field

[0001] The utility model relates to the field of water purification technology equipment for rivers and lakes, and in particular to a biological carbon source bacteria nest module combination device for water treatment. Background Art

[0002] As the scale of economic development grows, the total amount of sewage discharge continues to increase. The nitrogen in the tailwater of sewage treatment plants mainly exists in the form of nitrates and ammonium ions. Therefore, the above removal has become a difficult problem to be solved in the treatment of tailwater from urban sewage treatment plants.

[0003] Among the above problems, the main reason that restricts the removal of nitrogen in the tail water is the low organic carbon content in the tail water, which makes it difficult to meet the demand of denitrifying bacteria for carbon sources during the denitrification process, resulting in low denitrification efficiency. The reason is that there is no container device loaded with carbon source reactants for release in the sewage pool. Or to be more accurate, even if there are similar containers that release the aforementioned reactants, it is actually necessary to solve the problems of the release rate of the container-released substances and the reaction rate affected by the structure. At present, some technicians in this field have made some attempts, such as CN210419423U-"A slow-release composite carbon source rapid denitrification ball", and CN208071420U-"Slow-release composite carbon source rapid denitrification ball". There is also a technical solution for biowax CN212640087U-"A biowax block for water purification". Although attempts have been made in sewage treatment, the overall effect is general, and only some problems or purification of local locations can be solved. In addition, the concept of vertical depth stratification treatment of sewage is not reflected. Utility Model Content

[0004] In order to solve the shortcomings and defects mentioned in the background technology, the utility model provides a biological carbon source fungus nest module assembly device for water treatment, which is used to provide an assembly device to embody the slow release of carbon source materials. The specific scheme is as follows:

[0006] A reactant container placed in a depth range from below the water surface to above the water bottom, the reactant container having a plurality of chambers, each chamber being connected to an external water area, and the chambers containing a slow-release carrier material and a first type of reactant;

[0007] A support component is arranged in a vertical state for the reactant container to be suspended and fixed so that the reactant container is kept in the immersion water, and a plurality of bio-nest units are connected to the periphery of the support component;

[0008] The base is used to anchor the lower end of the supporting component to the bottom of the water.

[0009] Furthermore, the supporting component is a straightened rope or a supporting rod.

[0010] Furthermore, the bio-nest unit is a carbon fiber braid, which provides for the formation of an external microbial biofilm and promotes the growth of the biofilm.

[0011] Furthermore, a counterweight is provided below the reactant container, and the counterweight is used to offset the buoyancy exerted on the reactant container.

[0012] Furthermore, the biological carbon source bacteria nest module assembly device for water treatment also includes a float to be fixedly connected to the upper end of the supporting component.

[0013] Furthermore, an auxiliary reactant underwater container is arranged on the periphery of the base for filling the micro-electrolysis reactants therein.

[0014] Furthermore, the multiple chambers are separated from the inside to the outside by a plurality of grids, and each grid has radially connected through holes.

DETAILED DESCRIPTION

[0023] The drawings are only for illustrative purposes and cannot be construed as limiting the present invention. To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0024] The same or similar numbers in the drawings of the embodiments of the utility model correspond to the same or similar parts; in the description of the utility model, it should be understood that if the terms "upper", "lower", "left", "right", "long", "short" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, they are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0025] Before disclosing the specific technical solution of the utility model, it can be known from the information of the prior art that the existing technical solution of biological denitrification has the characteristics of high efficiency, low consumption, environmental friendliness, etc., and has been widely used in sewage treatment processes.

[0026] As we all know, nitrification and denitrification are key links in the biological denitrification process. In the denitrification reaction, heterotrophic denitrifying bacteria use organic carbon sources as electron donors to convert nitrite nitrogen or nitrate nitrogen into nitrogen gas. Carbon source materials are key factors in the denitrification reaction. Therefore, the process of treating sewage often requires external input of carbon source materials to promote denitrification and enhance the denitrification effect. Common carbon source materials include small molecular organic matter such as methanol, ethanol, acetate, as well as sugars such as sucrose and glucose, and sodium acetate. These liquid or highly soluble carbon sources are easily decomposed and utilized by microorganisms. However, the above-mentioned approach will inevitably lead to high operating costs and make the organic carbon content easily exceed the standard. In addition, conventional carbon source materials are also accompanied by other deficiencies, such as plant materials. In the early stage of use, the values ​​of suspended solids, chromaticity, turbidity and other indicators involved in plant materials are all high. In addition, this type of material softens after long-term soaking, and it is very easy to block narrow places, and the stability and durability of its carbon release are also poor.

[0027] In addition, plant-based carbon source materials can be easily obtained locally, are green and harmless, and have a high organic matter content, and can be used as carbon sources and microbial carriers. However, there is currently a lack of containers that can balance the carbon source release rate and the treatment of waste at different depths in the water. In response to the above problems, the utility model discloses a biological carbon source fungus nest module combination device for water treatment, which can provide a long-term and stable carbon source for microorganisms, and even provide other trace nutrients, thereby promoting the improvement of biological denitrification efficiency.

[0028] See also Figure 1-Figure 4 As shown, the utility model provides a bio-carbon source fungus nest module assembly device for water treatment, which includes but is not limited to: a reactant container 1, a support component 30 and a base, etc. The reactant container 1 is placed in a depth interval from below the water surface 5 to above the water bottom 6, and the buoyancy it receives may be in a suspended state. The reactant container 1 has a plurality of chambers, each of which is connected to the external water area, and the chambers are provided with a slow-release carrier material and a first type of reactant. The first reactant may be a single substance material or a multi-substance mixture, and from the inside to the outside, it includes but is not limited to a first chamber 11, a second chamber 12, and a buffer chamber 13 used for material exchange reaction and slowing down the rhythm of material release. The support component 30 is arranged in a vertical state. Here, the vertical state is only an estimated state. The understanding should not be limited to the text. The support component 30 is used for the reaction container 1 to be suspended and fixed. If the buoyancy of the reaction container 1 is completely immersed in the sewage and is greater than the combined force of its own weight and the weight of the material carried, it is tightened; if the buoyancy of the reaction container 1 in the sewage is not enough to offset the force of its own weight and the weight of the material carried, it is suspended; in short, the purpose of setting the support component 30 is to keep the reaction container 1 always immersed in water, and a plurality of biological nest units 31 are connected to the periphery of the support component 30. The base is used to anchor the lower end of the support component to the bottom 6 of the water. The first chamber 11 and / or the second chamber 12 can be filled with a composite solid bio-carbon source wax module, which includes a carbon source material and a bio-wax material. The carbon source material is a renewable natural carbon source material, or a modified agricultural waste, such as wolfberry branches, corn cobs, peanut shells, rice husks, straw, etc., and other biodegradable polymer materials PCL, PHBV, etc., and at least one or a mixture of several. The bio-wax material is a mixture of modified beeswax, soybean wax and microcrystalline wax. The above-mentioned materials have a higher hardness of the slow-release composite carbon source wax block, and the melting point during processing is also low, which is conducive to improving the bioaffinity of the composite solid carbon source wax module. At the same time, it is also conducive to the attachment and growth of microorganisms, and effectively promotes the formation of biofilms.

[0029] As a preferred embodiment, the support member 30 can be a straightened rope or a support rod. When a rope is selected, it can be a nylon rope or a mixed rope of multiple existing materials. When a support rod is selected, it can be a composite rod mainly made of carbon fiber.

[0030] As a preferred embodiment, the bio-nest unit 31 is a carbon fiber braid. The bio-nest unit 31 can be in the shape of a strip, a rod, or a dendrite, so as to form an external microbial biofilm and promote the growth of the biofilm. The bio-nest unit 31 can also be a carbon fiber braided structure. With such a configuration, it has a large specific surface area, can adsorb a large number of microorganisms, has a high degree of biological affinity, and can quickly and efficiently form biofilms. The carbon fiber bio-nest has high strength, ultra-lightness, corrosion resistance, high temperature resistance, insolubility in water, long service life, and low maintenance costs. On a section of the biofilm formed on the surface of the carbon fiber, three reaction zones are formed from the outside to the inside: aerobic, facultative anaerobic, and anaerobic.

[0031] As a preferred embodiment, a mounting member and a counterweight member are provided below the reactant container 1 , wherein the mounting member is used to mount the reactant container 1 on the supporting member 30 , and the counterweight member is used to offset the buoyancy exerted on the reactant container.

[0032] As a preferred embodiment, the water treatment biocarbon source fungus nest module assembly device further includes a float 4 for fixed connection to the upper end of the support component. According to the above technical solution, the float 4 can be a hollow float or a floating plate, which provides a pulling force to the reactant container 1 when the weight of the reactant container 1 and the reactant material is greater than the buoyancy, so that the reactant container 30 remains suspended under the water surface.

[0033] As a preferred embodiment, the middle of the base is a counterweight 20, and the periphery of the counterweight 20 is provided with an auxiliary reactant underwater container 21 for the micro-electrolysis reactant to be filled therein. The auxiliary water treatment container filled with the micro-electrolysis reactant serves as a purification unit close to the bottom of the water. Under the action of the generated microelectrodes, the organic pollutants in the sewage will produce a series of redox reactions at the interface of the microelectrodes, forming an autocatalytic process, which greatly reduces the ammonia nitrogen, COD, nitrite, etc. in the sewage, and the pH value of the water around the microelectrodes will be weakly alkaline, and the dissolved oxygen will also increase. It can effectively control the redox potential, and at the same time, it can make the carbon-nitrogen ratio tend to be balanced, so that the water body becomes beneficial to the healthy reproduction of microorganisms.

[0034] As a preferred embodiment, the multiple chambers are separated from the inside to the outside by a plurality of grids, and each grid has radially connected through holes to facilitate the flow of sewage into the reactants and the release of the reactants to the outside.

[0035] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
