[0002] "No bottom mud" refers to an artificial lake with a cement bottom. Because of the cement bottom, the bottom of the lake does not have the ability to self-heal, and it is difficult to manage. Therefore, our biological island and bacterial agents are needed for management. However, since the existing bacterial agents are directly added to specific locations of the lake manually, the operation is relatively unchanged. Even if traditional delivery devices are used for delivery, the traditional delivery devices are not convenient for self-propelled mobile cleaning, the cleaning area is small, and it is not convenient to set the cleaning route according to the shape of the lake. It is also not convenient to quickly recover the precipitated impurities after the natural precipitation of the bacterial agent, which easily causes bottom mud accumulation.

[0030] Principles of sewage treatment

[0031] Biological islands replace bottom mud to carry microorganisms: biological fillers for microorganisms to attach and grow, such as ecological expanded clay, activated carbon, etc., are selected to provide a living environment for probiotics.

[0032] Strong reproductive capacity: The microbial population in the microbial agent has a very strong reproductive capacity and can reproduce rapidly in sewage and occupy a dominant position. This rapid reproduction characteristic enables the microorganisms to form a large biological community in a relatively short period of time, thereby effectively treating pollutants in sewage.

[0033] Fast metabolism: Microorganisms have a fast metabolism and can produce a variety of degradation enzymes. Under the action of microorganisms, these degradation enzymes can efficiently degrade organic matter in sewage and convert it into harmless substances such as carbon dioxide and water.

[0034] Synergistic effect of multiple microorganisms: There are various types of microorganisms in microbial agents, including multiple microorganisms that can degrade different pollutants. These microorganisms can cooperate with each other and gradually decompose complex organic matter in sewage into simple inorganic matter through different metabolic pathways. This synergistic effect makes microbial agents more efficient and stable in treating complex sewage.

[0035] Transformation ability of special microorganisms: Some special microbial strains can transform or degrade a variety of toxic substances, such as sulfur-containing and ammonia-containing gases, formaldehyde, benzene and other toxic substances. These microorganisms transform these harmful substances into harmless and odorless substances through adsorption, absorption and metabolism, thereby achieving the purpose of purifying water quality and improving environmental hygiene.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] The present invention uses a water self-purification device and the addition of biological agents to utilize the metabolic action of microorganisms to remove pollutants such as organic matter in the water body, degrade indicators such as COD, BOD, ammonia nitrogen, and total phosphorus, inhibit the growth of cyanobacteria, and achieve self-purification and ecological restoration of the water quality of the bottom mud artificial lake, effectively solving the problems of cyanobacteria outbreaks and black and smelly water.

[0038] The mobile device is used in conjunction with the purification installation parts, so that it can move on the bottom of the lake. The raised guide rail is used to guide the raised guide rail, and the raised guide rail can be set according to the shape of the lake, which can effectively increase the comprehensiveness of water treatment and better target the purification of non-flowing water. The elastically mounted fitting groove wheel can realize elastic fitting and extrusion of the raised guide rail, which can be applied to the turning places of the raised guide rail, is more practical, can continuously move on the bottom of the lake, and perform steering guidance work.

[0039] By using liquid surface floating island parts, the water area can be aerated. At the same time, in conjunction with the lifting spray ring, biological bacteria or flocculants can be sprayed in the water area for purification. The isolation mesh used can reduce the diffusion of aeration and flocculation impurities and play an isolation role. By using the floating floating island box, the spray ring can be lifted and lowered according to the water level. A row of spacing adapter springs can be used to space the lifting and lowering spray rings, which can automatically adapt according to the water level to ensure the uniformity of the application of bacteria and drugs.

[0040] The double-layer suction piece can automatically absorb and clean impurities on the lake bottom, improve the cleaning effect of lakes without bottom mud, and prevent silt accumulation from affecting the lake ecology. The inner tube is combined with the anti-adsorption sleeve and the rubber structure, which is not easy to damage aquatic plants. The double-layer structure also prevents aquatic plants from clogging the anti-adsorption sleeve and the inner tube, and is not easily squeezed and bent, thereby improving the stability of impurity absorption.

DETAILED DESCRIPTION

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] Embodiment 1: A biological agent for the treatment of a bottomless lake, the biological agent being composed of the following formula: 5-95 parts of Bacillus subtilis, 5-95 parts of photosynthetic bacteria, 10-80 parts of nitrifying bacteria, 10-80 parts of denitrifying bacteria, 5-75 parts of Thiobacillus, 5-75 parts of anaerobic ammonia-oxidizing bacteria, 3-70 parts of phosphate-solubilizing bacteria, 3-70 parts of sulfate-reducing bacteria, 10-70 parts of lactic acid bacteria and 10-60 parts of yeast.

[0057] Adding auxiliary ingredients: Adding appropriate amounts of nutrients, trace elements, stabilizers and protective agents to the biological agent. These ingredients can improve the activity and stability of the agent, extend the shelf life of the agent, and enhance the agent's ability to degrade pollutants. The added nutrients include, but are not limited to: carbon sources, nitrogen sources, phosphorus sources, inorganic salts, trace elements. The added stabilizers include at least one of glycerol, gelatin and lactitol. The added protective agents include at least one of sodium alginate, glycerol and β-cyclodextrin.

[0058] Equipment used: sterile operating table, constant temperature incubator, shaker, centrifuge, spectrophotometer and other experimental equipment to ensure sterile operation and precise control of the experimental process.

[0059] The role of bacteria:

[0060] (1) Bacillus subtilis

[0061] Function: Bacillus subtilis plays an important role in sewage treatment. It is an aerobic bacteria that can effectively decompose organic matter, reduce the chemical oxygen demand (COD) and biochemical oxygen demand (BOD) in sewage, and use enzymes to decompose complex organic matter in sewage and improve the biodegradability of sewage. At the same time, Bacillus subtilis can inhibit the growth of harmful bacteria by competing and producing antibacterial substances, thereby improving water quality.

[0062] (2) Photosynthetic bacteria

[0063] Function: Photosynthetic bacteria are a type of bacteria that can perform photosynthesis. They can use light energy, carbon dioxide and small organic molecules to grow and reproduce. In sewage treatment, photosynthetic bacteria can degrade pollutants such as organic matter, ammonia nitrogen and nitrite, while also inhibiting the growth of harmful algae and improving the transparency and self-purification ability of water bodies.

[0064] (3) Nitrifying bacteria

[0065] Function: Nitrifying bacteria are mainly responsible for converting ammonia nitrogen in sewage into nitrite and then into nitrate, which is a key step in the nitrogen cycle in sewage treatment. Through nitrification, ammonia nitrogen in sewage can be removed, thereby reducing the toxicity of water to aquatic organisms.

[0066] (4) Denitrifying bacteria

[0067] Function: Denitrifying bacteria are responsible for further reducing the nitrate produced by nitrifying bacteria into nitrogen gas and releasing it into the air, thus completing the complete removal of nitrogen. This process is of great significance for reducing eutrophication of water bodies and preventing black and smelly water bodies.

[0068] (5) Thiobacillus

[0069] Function: Thiobacillus is a type of bacteria that can oxidize sulfide and produce sulfuric acid. In the treatment of wastewater containing sulfide, Thiobacillus can play an important role in removing sulfide in wastewater through oxidation, thereby reducing its toxicity. In addition, Thiobacillus can also work synergistically with other microorganisms to promote the degradation of other pollutants in wastewater.

[0070] (6) Anaerobic ammonium oxidizing bacteria:

[0071] Function: Anaerobic ammonium oxidizing bacteria are bacteria that can directly convert ammonia nitrogen and nitrite into nitrogen gas under anaerobic conditions. This process does not require oxygen and organic carbon sources, so it has high energy efficiency and environmental value. In sewage treatment, anaerobic ammonium oxidizing bacteria can be used as an effective means of denitrification to reduce nitrogen emissions.

[0072] (7) Phosphate-solubilizing bacteria:

[0073] Function: Phosphate-solubilizing bacteria are a type of bacteria that can decompose organic and inorganic phosphorus compounds and release soluble phosphorus. In sewage treatment, phosphate-solubilizing bacteria can decompose phosphorus sources in sewage and increase the availability of phosphorus in water, thereby helping to remove phosphorus pollution. In addition, phosphate-solubilizing bacteria can form a symbiotic relationship with plant roots, promoting the absorption and utilization of phosphorus by plants.

[0074] (8) Sulfate-reducing bacteria:

[0075] Function: Sulfate-reducing bacteria are a type of bacteria that can reduce sulfate to sulfide under anaerobic conditions. In sewage treatment, they can remove sulfate from water through this process, thereby reducing the acidity of the water and the toxicity of heavy metals. In addition, sulfate-reducing bacteria can also work synergistically with denitrifying bacteria to improve the denitrification effect of sewage.

[0076] (9) Lactic Acid Bacteria (LAB):

[0077] Function: Although lactic acid bacteria are not the mainstream bacteria in sewage treatment, they can also play a certain role under certain conditions. For example, in a low temperature or low pH environment, lactic acid bacteria can secrete organic acids such as lactic acid to lower the pH value of sewage, thereby inhibiting the growth of harmful microorganisms and promoting the degradation of organic matter.

[0078] (10) Yeasts:

[0079] Function: Yeast is mainly used as a bioflocculant or biosorbent in sewage treatment. It can absorb and remove pollutants such as suspended solids and heavy metal ions in sewage, improving the purification effect of sewage. In addition, yeast can also secrete some biologically active substances, such as enzymes and antibiotics, which have an impact on the microbial community in sewage.

[0080] These strains can work together to promote the decomposition of organic matter, the removal of nitrogen and phosphorus, and the inhibition of cyanobacteria. The culture solution can be used as a stabilizer and protective agent to a certain extent to ensure the activity and stability of the bacterial agent during storage and use.

[0081] A method for preparing a biological agent for treating a bottomless lake comprises the following steps:

[0082] S1. Activation culture: inoculate the preserved strains into fresh culture medium for composite activation culture. Observe the growth of the composite strains under suitable temperature and light conditions to ensure that the composite strains are reactivated and in a good growth state.

[0083] S2. Expanded culture: The activated strains are inoculated into a larger culture container for expanded culture. The culture conditions (such as temperature, pH value, dissolved oxygen, etc.) are controlled to promote the rapid growth and reproduction of the strains. During the culture process, samples are taken regularly to test the concentration and activity of the strains to ensure that the growth of the strains meets the requirements.

[0084] S3, homogenization treatment: by stirring or oscillating, the mixed strains and auxiliary ingredients are fully mixed to form a homogenized microbial agent. The homogenization treatment can ensure that the components in the microbial agent are evenly distributed and improve the use effect of the microbial agent;

[0085] S4. Packaging: The prepared microbial agent is packaged. The packaging container should be made of sterile and well-sealed materials, such as glass bottles and plastic bottles. During the packaging process, care should be taken to avoid contamination and leakage to ensure the purity and activity of the microbial agent.

[0086] S5. Storage: Store the packaged bacterial agent in a cool, dry, dark place to avoid direct sunlight and high temperature environment which may have adverse effects on the bacterial agent. At the same time, regularly check the storage condition of the bacterial agent to ensure that the bacterial agent maintains good activity and stability within the validity period.

[0087] refer to Figure 1 In this embodiment, a method of adding the biological agent for the treatment of the bottomless lake can be adopted, which is artificial placement. The method of using the biological agent for the treatment of the bottomless lake is as follows:

[0088] Dosage calculation

[0089] The dosage of bacterial agent should be reasonably calculated according to the scale of the treatment system, water quality and treatment objectives. Generally speaking, the dosage of bacterial agent for domestic sewage is about 1% - 30% (i.e. 10L - 300L per cubic meter), and the dosage of bacterial agent for industrial sewage is 10% - 45% (i.e. 100L - 450L per cubic meter).

[0090] Dosing point and time

[0091] Select appropriate locations in the artificial lake to set up dosing points (such as the center of the regional lake surface, around the floating island or at the intersection of water flows), and determine the dosing time and amount based on water quality monitoring results and treatment needs.

[0092] Dosing method

[0093] According to the water quality monitoring results, biological agents are regularly added to the lake. During the normal operation of the system, in order to maintain the activity and quantity of the bacteria, a batch addition method can be adopted, that is, the bacteria are divided into several batches and gradually added to the system over a period of time. Batch addition can reduce the shock load of the bacteria in the system, allow the bacteria to gradually adapt to the new environment, and help improve the treatment effect.

[0094] Direct dosing method: When re-dosing the bacterial agent at system startup or after overhaul, a one-time dosing method can be adopted, that is, the calculated total amount of the bacterial agent is added to the system at one time, and the bacterial agent is directly added to a specific location of the sewage treatment system, such as the water inlet of an anaerobic tank, aerobic tank or bioreactor. This method is simple to operate, but it should be noted that the bacterial agent may lose some activity due to water impact during the dosing process.

[0095] Dilution dosing method: Mix and dilute the bacterial agent with an appropriate amount of clean water or sewage, and then add it to the treatment system. The dilution dosing method can reduce the loss of the bacterial agent during the dosing process and help to evenly distribute the bacterial agent in the system.

[0096] Activation dosing method: For some bacterial agents that require specific environmental conditions, activation treatment can be carried out first. That is, the bacterial agent, nutrient source (such as glucose, urea, potassium dihydrogen phosphate, etc.) and water are mixed in a certain proportion and activated under suitable temperature and conditions. The activated bacterial agent has higher activity and can better adapt to the environment of the treatment system after dosing, thereby improving the treatment efficiency.

[0097] Continuous dosing: For some treatment systems that need to maintain a high bacterial concentration, a continuous dosing method can be used. That is, the bacterial agent is continuously dosed into the system at a constant flow rate through a special dosing device. This method can ensure the continuous supply and stable activity of the bacterial strain in the system, but attention should be paid to the precise control of the dosing amount and the stable operation of the dosing device.

[0098] Maintenance Management

[0099] 1. Regular inspection and monitoring

[0100] During the process of adding bacterial agents, water quality indicators and treatment effects should be monitored regularly, and the dosage and environmental conditions should be adjusted in time according to the monitoring results to ensure stable operation and efficient treatment of the treatment system.

[0101] Monitor changes in water quality indicators (such as COD, BOD, ammonia nitrogen, total phosphorus, etc.), evaluate treatment effects, and adjust treatment plans in a timely manner.

[0102] Regularly inspect and maintain the biological island, aeration equipment and bacterial agent addition points to ensure their normal operation and effective governance.

[0103] 2. Cleaning and repair

[0104] Regularly clean the plant residues and impurities in the biological fillers on the floating island to keep the floating island clean and promote plant growth.

[0105] 3. Supplementation and adjustment of microbial agents

[0106] According to the water quality monitoring results and treatment effects, the type and dosage of bacterial agents should be supplemented or replaced in a timely manner.

[0107] Adjust aeration intensity and operation time to adapt to water quality changes and treatment needs.

[0108] Advantages of microorganisms

[0109] 1. Strong environmental adaptability: The microorganisms in the microbial agent have strong environmental adaptability, are prone to mutation after being affected by environmental factors, and can form a rapid and effective material exchange with the surrounding environment. This enables the microbial agent to function under different water quality conditions, including changes in environmental factors such as temperature, pH value, and dissolved oxygen.

[0110] 2. Low temperature resistance and impact resistance: Some special microbial agents also have the characteristics of low temperature resistance and impact resistance. Even in low temperature or large fluctuations in water quality, these microorganisms can still maintain high activity and degradation ability to ensure the effectiveness of sewage treatment.

[0111] 3. Aerobic and anaerobic treatment: In practical applications, microbial agents can treat sewage in both aerobic and anaerobic ways. Under aerobic conditions, microorganisms oxidize and decompose organic matter into carbon dioxide and water through catabolism and anabolism; while under anaerobic conditions, microorganisms can decompose macromolecular organic matter into soluble substances, which are then further degraded into low molecular organic acids and alcohols by specific anaerobic bacteria, and finally produce gases such as methane.

[0112] 4. In-situ remediation: Use microbial agents to treat water bodies without pumping out the water. After the agents are added, they can rapidly proliferate and degrade pollutants in the water body, restoring the self-purification capacity of the water body in a short period of time. This in-situ remediation method not only saves time and cost, but also avoids secondary pollution that may occur during the transportation and treatment of the water body.

[0113] Principles of sewage treatment

[0114] Biological islands replace bottom mud to carry microorganisms: biological fillers for microorganisms to attach and grow, such as ecological expanded clay, activated carbon, etc., are selected to provide a living environment for probiotics.

[0115] Strong reproductive capacity: The microbial population in the microbial agent has a very strong reproductive capacity and can reproduce rapidly in sewage and occupy a dominant position. This rapid reproduction characteristic enables the microorganisms to form a large biological community in a relatively short period of time, thereby effectively treating pollutants in sewage.

[0116] Fast metabolism: Microorganisms have a fast metabolism and can produce a variety of degradation enzymes. Under the action of microorganisms, these degradation enzymes can efficiently degrade organic matter in sewage and convert it into harmless substances such as carbon dioxide and water.

[0117] Synergistic effect of multiple microorganisms: There are various types of microorganisms in microbial agents, including multiple microorganisms that can degrade different pollutants. These microorganisms can cooperate with each other and gradually decompose complex organic matter in sewage into simple inorganic matter through different metabolic pathways.
