Description

Technical Field

[0001] The present invention relates to the technical field of river sewage treatment, and in particular to a river sewage treatment bacterial agent, a treatment method and a treatment device. Background Art

[0002] Urban rivers and lakes are water environments that are closely connected with human production and life. With the growth of population and the acceleration of urbanization, a large amount of pollutants are directly discharged into rivers and lakes, resulting in a continuous increase in pollutants such as organic matter, ammonia nitrogen, total phosphorus and hydrogen sulfide in the water. The natural purification capacity of the water is seriously insufficient, which seriously restricts the sustainable development of the economy and the environment and endangers human health.

[0003] At present, although chemical methods are used to treat rivers, they can quickly reduce the concentration of pollutants in water bodies, but there are some disadvantages and possible secondary pollution problems. First, chemical treatment often requires the use of a large amount of chemical agents, which may contain harmful substances themselves. If not handled properly, the residual chemicals will have long-term effects on water bodies and ecosystems. Secondly, chemical agents may react with other substances in the water to produce new toxic byproducts, which will also cause harm to the environment and organisms. In addition, chemical treatment is usually costly and requires regular maintenance and monitoring, which increases the economic burden of treatment. The long-term use of chemical agents may also lead to changes in the structure of microbial communities and affect the self-purification ability of water bodies. Therefore, when choosing a river sewage treatment plan, it is necessary to comprehensively consider these disadvantages of chemical treatment and potential secondary pollution risks.

DETAILED DESCRIPTION

[0050] 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.

[0051] Embodiment 1:

[0052] In this scheme, the bacterial species of the sewage treatment bacterial agent include 10 to 90 parts of Bacillus phosphate, 5 to 80 parts of nitrifying bacteria, 5 to 80 parts of denitrifying bacteria, 5 to 60 parts of Bacillus, 3 to 65 parts of Micrococcus, 3 to 60 parts of Lactobacillus plantarum, 3 to 60 parts of Halophilus, 2 to 50 parts of Acetobacter, 2 to 50 parts of Methanogens, 2 to 30 parts of Methanogen Spirillum, 2 to 30 parts of Pseudomonas, and 2 to 30 parts of activating enzymes and polysaccharides;

[0053] The liquid culture medium is composed of carbon source, nitrogen source, phosphorus source and sulfur source to provide nutrients required for microbial growth;

[0054] In this scheme, the preparation method of the bacterial agent for river sewage treatment includes the following steps:

[0055] S1, inoculating 10 to 90 parts of Bacillus phosphate, 5 to 80 parts of nitrifying bacteria, 5 to 80 parts of denitrifying bacteria, 5 to 60 parts of Bacillus, 3 to 65 parts of Micrococcus, 3 to 60 parts of Lactobacillus plantarum, 3 to 60 parts of halotolerant bacteria, 2 to 50 parts of acetic acid bacteria, 2 to 50 parts of methanogenic bacteria, 2 to 30 parts of methanogenic spirochetes, 2 to 30 parts of Pseudomonas, and 2 to 30 parts of activated enzymes and polysaccharides into a liquid culture medium for culturing to obtain a composite mother bacteria;

[0056] S2, inoculating the composite mother bacteria into a fermentation tank for expansion culture, controlling the fermentation temperature at 25-40°C, and the fermentation time for 12-120 hours to obtain a composite sewage treatment bacterial agent fermentation liquid with an appropriate bacterial density;

[0057] S3. Fermentation and propagation to prepare bacterial agents. During the preparation process, the temperature, pH value and other conditions must be strictly controlled to ensure the activity and stability of the strain.

[0058] The carbon source is sugar or acetic acid; the nitrogen source is urea or potassium nitrate; the phosphorus source is phosphate or polyphosphate; the sulfur source is sodium bisulfate

[0059] In this scheme, the method for using a bacterial agent for treating river sewage is to place the bacterial agent upstream of the river. When using the bacterial agent, the bacterial agent is diluted in a certain proportion or placed in its original form.

[0060] The release amount is calculated according to the water quality monitoring data. When the river water quality is Class V water quality, the release amount is: 1%~30% of the total water body volume, which is released in 3-10 times; when the river water quality is Class IV water quality, the release amount is: 0.5%~20% of the total water body volume, which is released in 3-10 times; when the river water quality is Class III water quality, the release amount is: 0.1%~15% of the total water body volume, which is released in 3-10 times; if the river situation is complicated, such as a dead end river or excessive flow, the release amount will be appropriately doubled.

[0061] The main operation process is as follows: Figure 1 As shown, an aeration device is set up upstream of the river channel, and sewage treatment bacteria are added. The water flows to the sedimentation area to precipitate the sludge. The dam is then built to intercept the lower layer of turbid sludge, and the upper supernatant flows to the downstream river channel with the water flow; and the sedimentation area uses a pump to return the sludge to the aeration area.

[0062] refer to Figure 2 , the setting of aeration device

[0063] Location selection: Select a suitable location upstream of the river to set up the aeration area to ensure that the water can fully flow through the area and receive aeration treatment.

[0064] The equipment uses "high-pressure fan vacuum pump aerator equipment, aeration plate microporous nano oxygenation tube and aeration plate microporous nano oxygenation tube" and other equipment as aeration devices. The device has a microporous structure and can release oxygen into the water body evenly and efficiently, increase the dissolved oxygen content in the water body, and provide a good growth environment for sewage treatment bacteria.

[0065] The layout method is based on the width of the river and the water flow velocity, and the number and spacing of the aeration discs are reasonably arranged to ensure that the water in the entire aeration area can be fully aerated.

[0066] Addition of bacterial agents for sewage treatment.

[0067] Dosing method: The microbial agent is evenly added to the water in the aeration zone through a specific dosing device. The dosage is adjusted according to the water quality and treatment objectives to ensure that the microbial agent can fully play its role. Sludge sedimentation and dam interception.

[0068] Sedimentation zone setting: A sedimentation zone is set downstream of the aeration zone so that suspended matter and sludge in the water flow can gradually settle in this area.

[0069] Dam construction: Build a dam downstream of the sedimentation area to intercept and store the turbid sludge in the lower layer. The design of the dam needs to take into account the impact of the water flow and the sedimentation speed of the sludge to ensure the stability and interception effect of the dam. At the same time, an inclined or flat bottom structure should be set at the bottom of the sedimentation area to facilitate the sedimentation and collection of sludge. Supernatant discharge: The supernatant after sedimentation flows to the downstream river through the overflow port on the upper part of the dam to achieve clean and dirty water separation.

[0070] Sludge return system

[0071] System setup: A water pump and a return pipe are set up in the sedimentation area to pump the settled sludge back to the aeration area for further treatment. The sludge colonized with microorganisms is recycled to improve the efficiency and effect of sewage treatment.

[0072] Control strategy: According to the amount of sludge in the sedimentation area and the treatment effect, the flow rate and frequency of sludge return can be flexibly adjusted. When the amount of sludge is small or the treatment effect is good, the return flow can be appropriately reduced; otherwise, the return flow can be increased to enhance the treatment effect.

[0073] In this proposal, see Figure 1 - Figure 3 , sewage treatment bacterial agents are placed in the upper reaches of the river, and an aeration zone is set up at a suitable location in the upper reaches of the river to ensure that the water can fully flow through the area and receive aeration treatment. The equipment uses "high-pressure fan vacuum pump aerator equipment, aeration plate microporous nano-oxygenation tubes and aeration plate microporous nano-oxygenation tubes" and other equipment as aeration devices. The device has a microporous structure and can release oxygen into the water body evenly and efficiently, increase the dissolved oxygen content in the water body, and provide a good growth environment for sewage treatment bacterial agents;

[0074] In the downstream area of ​​the river channel, a sedimentation area is set up and a dam is designed to intercept. The bottom of the sedimentation area should be set up with an inclined or flat bottom structure to facilitate the deposition and collection of sludge. The designed sludge scraper 2 is located below the sedimentation area to return the settled sludge to the aeration area for further treatment;

[0075] The water flows to the downstream river channel through the overflow outlet at the top of the dam, realizing the separation of clean and dirty water.

[0076] Through the recycling effects of biological treatment and sludge return, a sustainable development management model has been formed.

[0077] See also Figure 4 - Figure 7, a river sewage treatment equipment shown in the figure is provided with a treatment equipment for placing bacterial agents for river sewage treatment, including two end plates 1, a mud scraping component 2 is installed between the two end plates 1, and the mud scraping component 2 is used to scrape the residual mud at the bottom, and the two end plates 1 are threaded with screw rods 3, the outer ends of the screw rods 3 are connected to the driving device, and the screw rods 3 are driven to rotate by the driving device; and a collecting frame 4 fixed to the two end plates 1, and driving pipes 5 are rotatably installed at both ends of the collecting frame 4, and a discharge assembly 6 is installed between the two driving pipes 5, and a linkage arc plate 7 is fixed between the two driving pipes 5; and a driving component 8 installed on the outside of the collecting frame 4, and the discharge assembly 6 is driven to rotate by the driving component 8; and a plurality of mud pumping pipes 9 fixedly connected to the bottom of the collecting frame 4, and the outer ends of the plurality of mud pumping pipes 9 are connected to the mud pump;

[0078] It should be noted that the treatment equipment used for the placement of bacterial agents for sewage treatment is as follows: Figure 1 As shown in the figure, the bacterial agent is mainly transported into the delivery tube by an external pipeline, and then discharged from a number of discharge pipes with valves at the bottom of the delivery tube, so as to deliver the bacterial agent into the river and play a role of bacterial delivery.

[0079] In this solution, the screw 3 is driven to rotate forward and backward through an external existing driving device, so that the two end plates 1 and the sludge scraper component 2 and the collecting frame 4 move forward and backward synchronously. During the movement, the sludge scraper component 2 scrapes off the sludge remaining at the bottom of the sedimentation area, thereby transferring part of the sludge at the bottom that is difficult to be adsorbed to the collecting frame 4, and pushing the sludge toward the sludge suction pipe 9 through the discharge component 6, and using the existing mud pump to transfer the sludge in the sludge suction pipe 9 to the upstream area of ​​the river channel, so as to degrade the microorganisms in the sludge again.

[0080] For further information, see Fig. 9 and Fig.13 The discharge assembly 6 includes a discharge rod 10 that is slidably plugged into the two drive tubes 5, and a discharge plate 11 is fixed to the outside of the discharge rod 10. The discharge rod 10 drives the rotation of the discharge plate 11, thereby guiding the sludge in the collection frame 4 into the sludge suction pipe 9 for discharge;

[0081] For further information, see Fig.10 - Fig.12 The driving component 8 includes a transmission gear 12 fixed to the outside of the driving tube 5, a linkage groove 13 is provided on the inner side of the driving tube 5, a linkage plate 14 slidably connected to the linkage groove 13 is fixed to the outer side of the discharging rod 10, a spring sheet 15 abutting against the linkage groove 13 is fixed to the outer side of the linkage plate 14, and a driving gear 16 meshing with the transmission gear 12 is rotatably installed on both sides of the collecting frame 4, a driving motor 17 is fixed to one side of the collecting frame 4 through a motor frame, and the output end of the driving motor 17 is fixed to the gear shaft of one of the transmission gears 12 through a coupling, and a vibrating member 18 is installed on the outer side of the discharging rod 10;

[0082] Among them, the vibrating member 18 includes a vibrating wheel 19 fixed on the outside of both ends of the discharge rod 10, and a plurality of protrusions 20 are fixed at equal angles on the outside of the vibrating wheel 19. Brackets 21 are fixed on both sides of the collecting frame 4, and an insert rod 22 is slidably inserted on the bracket 21. A resist bar 23 that fits the outside of the vibrating wheel 19 is fixed at one end of the insert rod 22, and an extrusion spring 24 that resists the resist bar 23 and the bracket 21 is sleeved on the outside of the insert rod 22.

[0083] The driving component 8 drives the discharge plate 11 to rotate: the driving motor 17 drives the driving gear 16 to rotate, so that the transmission gear 12 meshing with it rotates, driving the driving pipe 5 to rotate synchronously, and the linkage arc plate 7 is used to make the two driving pipes 5 rotate synchronously, and the transmission gear 12 and the driving gear 16 at the other end rotate synchronously. When the driving pipe 5 rotates, the linkage plate 14 extends into the linkage groove 13 and is resisted by the spring sheet 15, so that the rotation of the driving pipe 5 drives the discharge rod 10 to rotate, and the discharge plate 11 rotates in the collection frame 4, so that the sludge collected in the collection frame 4 can be discharged downward, which is convenient for the extraction of the sludge extraction pipe 9;

[0084] When the discharge rod 10 rotates, it will drive the vibration wheel 19 to rotate. During the rotation of the vibration wheel 19, several protrusions 20 on the outside will contact the resistance bar 23 and hinder the rotation of the vibration wheel 19, squeezing the spring sheet 15 until the spring sheet 15 is squeezed to the limit. The protrusion 20 squeezes the resistance bar 23, so that the squeezed spring sheet 15 releases the elastic force, thereby driving the discharge rod 10 to vibrate and vibrate the residual sludge on the outside to avoid sludge residue.

[0085] It should also be noted that the outer side of the support bar 23 is provided with an arc surface that fits with the outer side of the vibration wheel 19, so that the vibration wheel 19 and the support bar 23 fit stably.

[0086] For further information, see Figure 8 The scraper component 2 includes a driving roller 32 rotatably installed between the two end plates 1, and a transmission belt 33 is sleeved on the outer side of the two driving rollers 32. A rotating device for driving the driving roller 32 is installed between the two end plates 1. A plurality of scraper blades 34 are rotatably installed on the outer side of the transmission belt 33 through a rotating shaft. A track groove 35 is opened on the adjacent surfaces of the two end plates 1. A connecting rod 36 is fixed on the scraper blade 34 and is slidably connected to the track groove 35. A V-shaped groove is provided on the track groove 35. When the connecting rod 36 passes through the V-shaped groove, it drives the scraper blade 34 to rotate.

[0087] The principle of the scraper component 2 to scrape the sludge at the bottom of the sedimentation area is: through the existing rotating equipment, the two driving rollers 32 are driven to rotate, so that the transmission belt 33 rotates. The rotation of the transmission belt 33 will cause the multiple scraper blades 34 on the outside thereof to move back and forth, and scrape the sludge at the bottom of the sedimentation tank, and push the suspended sludge into the collection frame 4. A V-shaped groove is provided on one side of the track groove 35 close to the collection frame 4, so that the scraper blade 34 can rotate accordingly when passing through the V-shaped groove, such as Figure 4 shown.

[0088] The following is an introduction to the role of each bacterial species in the microbial agent:

[0089] Bacillus phosphate: It has strong environmental adaptability and can survive and reproduce under specific environmental conditions. In environmental pollution control, Bacillus phosphate may participate in the bioremediation process and degrade harmful substances in the environment.

[0090] Nitrifying bacteria and denitrifying bacteria: During the wastewater treatment process, nitrifying bacteria convert ammonia nitrogen into nitrate nitrogen, while denitrifying bacteria reduce nitrate nitrogen to nitrogen gas, thereby removing nitrogen pollutants from the wastewater.

[0091] Bacillus: They can regulate the balance of microbial communities and may help improve the microbial ecological balance in the environment or organisms. When a new sewage system is started, composite bacteria can quickly cultivate microorganisms and help the biochemical pool quickly form a stable biological community. In addition, they can also improve the system's ability to resist shock loads to cope with excessive organic matter loads.

[0092] Micrococcus: It has a certain ability to degrade organic matter and can work synergistically with other bacteria to improve wastewater treatment efficiency. In the sewage biochemical pool, when the organic matter concentration is too high or the dissolved oxygen in the biochemical pool is low, the high-load sewage is likely to cause an impact on the microorganisms. It can effectively remove COD indicators and stabilize the biochemical system.

[0093] Lactobacillus plantarum: It is a facultative anaerobic bacterium with strong ability to ferment glycogen and is relatively salt-tolerant.

[0094] It can produce a variety of antibacterial substances, such as citric acid, germicides, hydrogen peroxide and diacetyl.

[0095] Halophilic bacteria: a type of microorganism that can survive and function in a high-salinity environment. They are mainly isolated, screened and cultured from seawater and salt ponds, and are suitable for use in high-salinity, difficult-to-degrade wastewater biochemical systems. Halophilic bacteria can effectively improve the removal rate of TOC (total organic carbon), ammonia nitrogen, and toxic and hazardous substances in the biochemical system, while enhancing the stability and impact resistance of the system. In a high-salinity environment, they can regulate the osmotic pressure balance inside and outside the cell by metabolically accumulating compatible solutes, such as glutamic acid and proline, to prevent cell dehydration and damage.

[0096] Acetic acid bacteria: It is a mixed bacteria with many types, including both anaerobic bacteria and aerobic bacteria. It has strong acid resistance and requires oxygen during the fermentation process.

[0097] Methanogens: Anaerobic fermentation of inorganic or organic compounds into methane and carbon dioxide. They play an important role in the carbon cycle in nature and participate in the methanogenesis of organic matter.

[0098] Methanogenic spirochetes: microorganisms that convert inorganic or organic compounds into methane and carbon dioxide by anaerobic fermentation. They participate in the carbon cycle in nature and contribute to the treatment and utilization of organic waste. They have a specific morphological structure (such as a spiral shape) that helps them survive and reproduce in anaerobic environments.

[0099] Pseudomonas: It has strong ability to degrade organic matter and adapt to the environment, and can play a role in degrading various industrial wastewaters. COD-degrading bacteria mainly degrade COD indicators in wastewater, which can significantly improve water color, increase sludge floc particles, adjust sludge floc structure, and inhibit algae growth.

[0100] In this scheme, sewage can be treated and purified through the synergistic effect of various bacterial species, including:

[0101] Synergistic effect: Nitrifying bacteria and denitrifying bacteria work together to achieve nitrogen recycling. Nitrifying bacteria convert ammonia nitrogen into nitrate nitrogen, while denitrifying bacteria convert nitrate nitrogen into nitrogen gas under anoxic or anaerobic conditions, thereby removing nitrogen pollution in water bodies.

[0102] Microbial degradation: The microbial population in the bacterial agent has a very strong reproductive ability and a rapid metabolic rate. It can produce a variety of degradation enzymes to efficiently degrade organic matter in sewage.

[0103] Material cycle: Microorganisms gradually decompose complex organic matter in sewage into simple inorganic matter (such as carbon dioxide and water) through different metabolic pathways, realizing the recycling of materials.

[0104] Ecological restoration: Some special microbial strains can transform or degrade a variety of toxic substances (such as sulfur-containing and ammonia-containing gases, formaldehyde, benzene, etc.) and repair the pollution of the environment caused by toxic substances.

[0105] The composite bacteria have the ability to degrade various pollutants such as COD (chemical oxygen demand), BOD (biological oxygen demand), ammonia nitrogen, total nitrogen, etc., and have strong adaptability and can adapt to different water quality environments.

[0106] Example 2: Please refer to Fig.11 as well as Fig.12This embodiment is further described for the example, and the difference lies in that a knocking mechanism 25 is additionally provided on the outer side of the collecting frame 4, which can flow the residual sludge on the inner wall of the collecting frame 4.

[0107] Specifically, knocking mechanisms 25 are installed on both sides of the collection frame 4, and the knocking mechanisms 25 include half gears 26 fixed on the outside of the driving gear 16. Slide rails are fixed on both sides of the collection frame 4, and a force storage plate 27 is slidably inserted in the slide rails. A tooth row 28 meshing with the half gear 26 is fixed on one side of the force storage plate 27. A knocking rod 29 is fixed between the two force storage plates 27, and the outer wall of the collection frame 4 is impacted by the knocking rod 29. A sliding rod 30 fixed to the outer wall of the collection frame 4 is slidably inserted in the force storage plate 27, and a force storage spring 31 that resists the force storage plate 27 is sleeved on the outer side of the sliding rod 30.

[0108] In this solution, the driving gear 16 rotates, driving the half gear 26 to rotate, thereby driving the corresponding movement of the tooth row 28 and the force storage plate 27, and driving the knocking rod 29 to move outward. After the half gear 26 disengages from the tooth row 28, the squeezed force storage spring 31 is released, thereby driving the knocking rod 29 to knock on the outer wall of the collecting frame 4, thereby discharging the sludge adsorbed in the collecting frame 4.

[0109] Example 3: Please refer to Fig.13 This embodiment further illustrates other embodiments, and the difference lies in the optimization of the shape of the collection frame 4.

[0110] Specifically, the collecting frame 4 has an arc-shaped surface near the scraping component 2 , and the joints between the collecting frame 4 and the plurality of mud suction pipes 9 are inclined structures. The design of the arc-shaped piece makes it easier to scrape the discharge plate 11 .

[0117] in:

[0118] The data collected on February 22 was shallow surface water. After aeration, the bottom water was turned to the surface. The data collected again on March 2 reflected the real data of the water body. After treatment, the data collected on March 16 showed that the standard had been met. Although the total nitrogen index is still above the standard, it has been declining.

[0119] In this experiment, if more than two high-power aerators are introduced to form an efficient water cycle, the treatment cycle can be shortened to within one week. The experimental data is summarized for reference Fig.14 .

[0120] Project name: Biological treatment of black and smelly water in the Gaozhuang Bridge channel of Zhuxi River in Junan County, Linyi City.

[0121] Problem: Due to the discharge of a large amount of pollutants into the local area, COD, phosphorus, etc. are seriously exceeded, and the chemical coagulant treatment is ineffective, resulting in secondary pollution. For specific details, please refer to the attached Fig.15 .

[0122] Used bacteria: HS-CP-XXX series of bacterial strains, composite microbial flora, wastewater monitoring structure table, please refer to the attached Fig.16 .
