Description

Technical Field

[0001] The utility model mainly relates to the technical field of river and lake management, and specifically relates to a river and lake management composite device with high-efficiency biological bacteria. Background Art

[0002] With the advancement of economic development, the water quality of my country's rivers and lakes has been declining continuously. Among the seven major river systems in the country, the water quality of many river sections is mainly Class IV to V water, and in some local areas it is even worse than Class V water, and has lost its function as a source of drinking water. In order to improve the ecological benefits of rivers and lakes and restore the river and lake ecosystems, river and lake management is urgent.

[0003] At present, there are three common methods of river and lake management on the market. The first is to use chemical flocculants to separate harmful organic matter from the water body through chemical separation; the second is to use aquatic plants to absorb and consume harmful organic matter in the water body through the principle of absorption by the roots of aquatic plants; the third is to use biological agents to degrade and decompose pollutants in the water body through the principle of biodegradation.

[0004] The above three methods of river and lake management have been widely used in the field of river and lake management, but they all have certain defects, and various problems have arisen in the actual management process.

[0005] Using chemical flocculants to repair the water quality ecology of rivers and lakes is quick and effective, but equipment is needed to add the flocculants for reaction, and the addition frequency is frequent, which only treats the symptoms and not the root cause. The quality of water depends entirely on the amount of flocculants added. In the long run, not only is the treatment cycle long and the treatment cost high, but the continuous use of chemical flocculants will also cause secondary pollution to the ecology.

[0006] Planting aquatic plants in the treated water and using their roots to absorb harmful substances is a low-carbon and sustainable treatment solution, but it is difficult to operate in practice. The growth of aquatic plants is affected by factors such as climate and environment, and the absorption capacity of a single plant is limited. If the pollutant content in the water is too high and the water quality is too poor, the plants will die. In order to maintain the good growth state of the plants, a certain amount of manpower, material resources and financial resources are also required.

[0007] The common biological agents with water body restoration effects on the market now need to be cultivated in advance and then added to the treated water body, using their biological characteristics to decompose and degrade harmful organic matter in the water body. Through practical cases and scientific research, it can be clearly found that such biological agents have low reproduction capacity and short-lasting effects. Generally, additional releases are required every 2-3 months, and the subsequent operating costs are high.

[0008] The inventor has proposed a composite device for river and lake management with high-efficiency biological bacteria, which can be directly applied to the management of water bodies without cultivation, thus solving the current problems in the field of river and lake management.

Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0041] See attached Figure 1-4 The utility model provides a composite device for river and lake management with high-efficiency biological bacteria, including the following structure:

[0042] The buoy 1 has a green plant cultivation area fixedly disposed on the top thereof and a buoyancy reserve chamber fixedly disposed on the inner side thereof.

[0043] The material rack 2 has a storage cavity fixedly disposed on the inner side thereof, and the material rack 2 can be filled with biological carrier filter material 3 and / or biological mineral filler 4.

[0044] In this embodiment, Figure 1 and Figure 2 As shown, it also includes a biological solidification breeding area 5:

[0045] At least three material racks 2 are arranged horizontally in the biological solidification breeding area 5. The three material racks 2 in the biological solidification breeding area 5 are filled with biological carrier filter material 3 and biological mineral filler 4, biological carrier filter material 3, and biological mineral filler 4 in sequence along the sewage flow direction.

[0046] The biological solidification breeding area 5 is provided with biological carrier filter material 3 and deep biological mineral filler 4. Considering the serious pollution in the upper reaches of rivers and lakes, it can be selected whether to add aeration equipment to assist this product in treating sewage.

[0047] The high adsorption and high hydrophilicity of the biological carrier filter material 3 are conducive to the long-term reproduction and attachment of microorganisms. The high surface area produced by the porosity of the deep biological mineral filler 4 can effectively cultivate nitrifying bacteria in the water, which is conducive to the fixation and biofilm growth of microorganisms, thereby promoting the reproduction and growth of microorganisms.

[0048] In this embodiment, Figure 1 and Figure 2 As shown, it also includes a biological reproduction purification area 6:

[0049] At least three material racks 2 are arranged horizontally in the biological propagation and purification area 6. The three material racks 2 in the biological propagation and purification area 6 are filled with biological carrier filter material 3, biological mineral filler 4, and biological mineral filler 4 in sequence along the flow direction of sewage.

[0050] After reproduction and growth, the microorganisms enter the biological reproduction and purification area 6. The biological carrier filter material 3 and the biological mineral filler 4 in the biological reproduction and purification area 6 mainly promote the reproduction quantity and activity of the microorganisms and further purify the pollutants.

[0051] In this embodiment, Figure 2 As shown, the biological reproduction and purification zone 6 is provided with a biological enhancement zone 7 at its end along the flow direction of the sewage.

[0052] The third material rack 2 at the end of the biological reproduction and purification area 6 works in the biological enhancement area 7, and the biological mineral filler 4 inside it improves the quality and efficiency of the composite biological functional bacteria. This stage is the biological reaction enhancement stage in the utility model. Through the adsorption effect brought by the high surface area of ​​the porous mineral filler, the activity and number of microorganisms are stimulated to the maximum extent, and the microorganisms are reproduced for a long time, and iron ions and hydrogen sulfide are degraded and eliminated, thereby improving water quality and odor.

[0053] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the material rack 2 is fixedly arranged in the deep layer and / or shallow layer of the water area.

[0054] Taking into account the anaerobic and aerobic requirements of sewage treatment, the depth of the rack 2 in the treated water area is adjusted according to the sewage treatment process, that is, the rack 2 is placed in the deep layer and / or shallow layer of the water area as needed.

[0055] The comprehensive treatment of polluted water bodies can be achieved by planting plants with water purification function on the buoy 1.

[0056] In this embodiment, Figure 2 and Figure 3 As shown, a plurality of racks 2 can be distributed vertically for use, adjacent racks 2 are fixedly connected by cables, and water gaps are fixedly provided between adjacent racks 2 .

[0057] According to the depth of the treated water area and considering the full contact between the water body and the biological mineral filler 4 and the biological carrier filter material 3, the material rack 2 is designed in layers in the vertical direction to avoid excessive accumulation of the biological mineral filler 4 affecting the sewage treatment efficiency.

[0058] Working principle:

[0059] The technical solution adopted by the utility model to solve its technical problems is to utilize the powerful resource predatory nature of high-efficiency biological bacteria to aggressively snatch organic pollutants, thereby reducing organic pollutants such as ammonia nitrogen, total nitrogen, sulfide, etc., increasing dissolved oxygen in water bodies, inhibiting and preventing other harmful bacteria, and eliminating water eutrophication, turbidity, black and smelly phenomena, stimulating the survival ability of indigenous bacteria, achieving low-carbon operation, simple operation, and improving the self-purification ability of water bodies.

[0060] Governance is divided into five processes.

[0061] Aerobic decomposition: Composite biological functional bacteria degrade and digest waste in an oxygen-rich environment. During the aerobic decomposition process, organic pollutants are decomposed into carbon dioxide, water, nitrates, and sulfates. These substances, together with nitrogen oxides, become nutrients for microbial growth. Combined with aeration equipment to supply oxygen, this process can be significantly accelerated.

[0062] Anaerobic decomposition: Water quality with extremely serious pollution requires a period of anaerobic treatment to eliminate substances such as nitrates, and then aerobic decomposition can quickly restore the activity of the sediment, activate the indigenous microorganisms of the sediment, open up the base point of the ecological chain, change the physical structure of the sediment, and restore the natural ecological system. After the original mud body has undergone structural transformation, it has physical properties such as granular structure, hydrophilicity, and air permeability.

[0063] Improve ion activity and microbial attachment: By setting bio-balls in anaerobic substrates, iron ions react with malodorous and biologically harmful hydrogen sulfide ions to become harmless iron sulfide, inhibiting the production of hydrogen sulfide, resolving and eliminating odors, degrading COD, ammonia nitrogen and other harmful substances, improving transparency, and inhibiting the production of algae. The silicon dissolved in the bio-balls can promote the production of beneficial diatoms and increase the number of diatoms, thereby absorbing and reducing inorganic nitrogen and phosphorus in the water.

[0064] Constructing a microbial system in a granular structure environment: After achieving in-situ reduction of the sediment, the density of the mud of a certain thickness on the surface increases, creating better prerequisites for the construction of the soil aggregate structure. Combined with the use of complex biological agents in water bodies, the ecology of the sediment environment can be enhanced, and the riverbed sediment will eventually become a bed of microorganisms or indigenous microorganisms in the river, completing the initial construction of the microbial system.

[0065] Build a sustainable plant and animal ecosystem: After improving the bottom mud environment, combine the improvement of aquatic plants and aquatic animal systems to achieve self-repair and sustainable development of the water ecosystem.

[0066] Aerobic and anaerobic merging: while degrading harmful organic matter such as ammonia nitrogen and COD in water bodies, it can also degrade harmful substances such as sulfide in sediments, achieving comprehensive management of water bodies and sediments.

[0067] Safe and efficient: It has strong reproductive capacity and long-lasting effect. It is not a chemical agent and will not cause secondary pollution.

[0068] Restore the ecological chain: coexist with existing organisms, improve the environment and restore the damaged ecological chain.

[0069] Simple construction and low cost: no large equipment is required, no engineering investment is required, and the overall cost is low.

[0070] Effectively decompose bottom mud: It can decompose harmful substances such as sulfide and hydrogen sulfide in the anaerobic layer, improve odor, decompose and reduce sludge

[0071] High adsorption stability: It can coexist with beneficial organisms and activated sludge organisms and can work together to exert purification effects, effectively improving purification capacity.

[0072] Survival rate: The composite biological functional bacteria have strong environmental adaptability and can reproduce in water temperatures above zero degrees. They can also have good biodegradability within the pH range of 3.6-12.

[0073] Strong hydrophilicity: Bioballs can decompose toxic substances in water and convert them into relatively less toxic or non-toxic substances, which can improve water quality.

[0074] Make the ions in the water active: It increases the content of oxygen ions and can slightly release alpha rays and infrared rays, which have a positive repair and enhancement effect on aquatic organisms.

[0075] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
