Description

Technical Field

[0001] This utility model patent work is a rural sewage treatment device related to the field of sewage treatment equipment. Background Art

[0002] Rural sewage treatment equipment uses biological, physical or chemical methods to meet emission standards, thereby protecting the rural environment and residents' health. These devices not only have high purification efficiency, but are also energy-saving and environmentally friendly, occupy a small area, and are easy to operate, bringing significant economic and social benefits. They are widely used in rural residential areas, farmland irrigation and other places, and play a vital role in improving rural environmental sanitation, improving the quality of life of residents and promoting sustainable agricultural development. Regular equipment maintenance is equally important to ensure stable operation and treatment effects, and to help build beautiful villages.

[0003] The inventor of this application found that there are the following problems in the practical use process:

[0004] In my country's vast rural areas, domestic sewage disposal has always been a prominent shortcoming in the improvement of the human settlement environment. By consulting relevant data from CNKI documents and investigating the rural human settlement environment, it was found that in some villages and towns, black and smelly water bodies, garbage waterways, and sewage treatment have not been synchronized with rural toilet reforms, resulting in a large amount of sewage being discharged directly. The phenomenon is becoming increasingly serious. The facilities provided by related companies are of high cost, complicated procedures, and difficult operations, which need to be urgently addressed. Specifically, there are three traditional forms of sewage treatment: physical treatment, chemical treatment, and biological treatment. In its traditional form, organic pollutants in sewage are degraded through the metabolism of microorganisms. Biological treatment has little impact on the environment, no secondary pollution, and stable treatment effect. However, the current form of biological treatment only relies on the microorganisms themselves to treat sewage, and fails to achieve a good purification effect, resulting in poor purification effect and slow efficiency. Its sewage purification efficiency still needs to be improved.

[0005] Therefore, it is necessary to provide a rural sewage treatment device to solve the above technical problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is that the efficiency of traditional sewage treatment is relatively low. Aiming at the above-mentioned defects of the prior art, a rural sewage treatment device is provided.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is: a rural sewage treatment device, comprising an outer ring, an inner cylinder mechanism is arranged on the inner side of the outer ring, the inner cylinder mechanism comprises a first inner cylinder and a second inner cylinder, a gas-liquid delivery pipe is arranged between the first inner cylinder and the second inner cylinder, an acid-base neutralization liquid medicine box and a nutrient solution medicine box are arranged on the upper part of the outer side of the first inner cylinder, a temperature control layer is arranged on the outer side of the first inner cylinder, a plant planting plate is arranged on the outer side of the bottom end of the first inner cylinder, an air pump is arranged on the top of the acid-base neutralization liquid medicine box, and a stirring blade is suspended on the inner side of the second inner cylinder.

[0008] By adopting the above technical solution, the device effectively promotes the growth and reproduction of microorganisms through the internal microbial culture environment, namely the "internal expansion" part. By precisely controlling key environmental factors such as pH value, temperature, dissolved oxygen, and providing necessary nutrient solution and light, the device ensures that the microorganisms are expanded and propagated under optimal conditions, thereby enhancing their purification function.

[0009] It is further arranged that the gas-liquid delivery pipe is connected with the acid-base neutralization liquid medicine box and the nutrient solution medicine box through an external gas-liquid pump.

[0010] By adopting the above technical solution, the device can automatically and accurately adjust the pH value and nutrients in the microbial culture solution. By timely adding acid-base neutralizing solution, it can ensure that the microorganisms grow in the most suitable pH environment, thereby improving their activity and reproduction rate.

[0011] It is further provided that the gas-liquid delivery pipe is connected to the outside through an air pump to provide oxygen and carbon dioxide required by the microorganisms.

[0012] By adopting the above technical solution, the required oxygen and carbon dioxide can be continuously provided to microorganisms, which ensures that the microorganisms have sufficient oxygen supply when performing aerobic respiration, thereby maintaining their normal physiological activities and reproductive capacity. Filling with appropriate concentrations of oxygen and carbon dioxide is a key factor in the metabolism and growth of microorganisms.

[0013] It is further arranged that the inflation pump, the temperature control layer and the gas-liquid pump are all electrically connected to an external power supply through a control center.

[0014] By adopting the above technical solution, the entire system can be automatically controlled and powered by an external power supply to ensure that key components work stably and continuously, thereby maintaining the stability and consistency of the microbial culture environment.

[0015] It is further provided that the plant planting plate is a natural wetland-like plate for cultivating algae and complementing the propagation of microorganisms.

[0016] By adopting the above technical solution, the plant planting board is set up as a natural wetland-like system, which introduces a natural ecological treatment link into the sewage treatment system. Algae can produce oxygen through photosynthesis, provide more dissolved oxygen for microorganisms, and absorb and utilize nutrients in sewage at the same time.

[0017] It is further provided that a partition is provided inside the second inner cylinder for dividing the interior of the second inner cylinder into four parts for culturing different microbial colonies.

[0018] By adopting the above technical solution, four different microbial colonies can be cultured at the same time. This separation provides an independent and stable environment, which is conducive to the growth and reproduction of various microorganisms under optimal conditions.

[0019] It is further provided that a pre-treatment grid is provided above the outer side of the outer ring for filtering solid debris in the sewage.

[0020] By adopting the above technical solution, the pretreatment grid is arranged above the outer side of the outer ring, which can effectively filter out larger debris in the sewage, such as paper scraps, plastic fragments, etc., which helps to protect the normal operation of subsequent treatment units and prevent debris from clogging or damaging the equipment.

[0021] Compared with the related art, the rural sewage treatment device provided by the utility model has the following beneficial effects:

[0022] The utility model provides a rural sewage treatment device. Through the inner cylinder mechanism, the device realizes the efficient propagation of microorganisms by finely controlling various environmental indicators required for the growth of microorganisms, such as pH value, temperature, dissolved oxygen, etc. in the inner cylinder, which makes full use of the degradation ability of microorganisms to pollutants, thereby improving the biological purification efficiency of sewage treatment. At the same time, the device combines traditional sewage treatment methods, such as simulating natural wetland treatment through plant planting plates to further remove harmful substances in sewage. This structural form of combining "internal propagation" with "external treatment" not only utilizes the biological purification effect of microorganisms, but also strengthens the traditional sewage treatment process, thereby achieving efficient and comprehensive purification effects of sewage.

DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show typical embodiments of the present invention.

[0029] Embodiment 1:

[0030] like Figure 1-4 As shown, a rural sewage treatment device of the utility model comprises an outer ring 1, an inner cylinder mechanism 3 is arranged on the inner side of the outer ring 1, the inner cylinder mechanism 3 comprises a first inner cylinder 301 and a second inner cylinder 302, a gas-liquid delivery pipe 303 is arranged between the first inner cylinder 301 and the second inner cylinder 302, an acid-base neutralization liquid medicine box 307 and a nutrient solution medicine box 308 are arranged on the upper side of the outer side of the first inner cylinder 301, a temperature control layer 306 is arranged on the outer side of the first inner cylinder 301, a plant planting plate 305 is arranged on the outer side of the bottom end of the first inner cylinder 301, an air pump 309 is arranged on the top of the acid-base neutralization liquid medicine box 307, and a stirring blade 310 is suspended on the inner side of the second inner cylinder 302. The device is provided by internal The set microbial culture environment, namely the "internal expansion and propagation" part, effectively promotes the growth and reproduction of microorganisms. By precisely controlling key environmental factors such as pH, temperature, dissolved oxygen, and providing necessary nutrient solution and light, the device ensures that the microorganisms are propagated under optimal conditions, thereby enhancing their purification function. At the same time, the device combines traditional sewage treatment methods, namely the "external treatment" part, such as simulating natural wetland environments through plant planting plates to further treat sewage that has been initially purified by microorganisms. This structural form of "internal expansion and propagation" and "external treatment" realizes the complementary advantages of traditional treatment forms and biological purification methods, and significantly improves the efficiency and effectiveness of sewage treatment.

[0031] like Figure 1 , Figure 2As shown, the gas-liquid delivery pipe 303 is connected to the acid-base neutralizing liquid medicine box 307 and the nutrient solution medicine box 308 through an external gas-liquid pump, so that the device can automatically and accurately adjust the pH value and nutrients in the microbial culture solution. By adding the acid-base neutralizing liquid in time, it can ensure that the microorganisms grow in the most suitable pH environment, thereby improving their activity and reproduction rate. At the same time, the gas-liquid delivery pipe 303 located between the first inner cylinder 301 and the second inner cylinder 302 is evenly arranged, and the acid-base neutralizing liquid and the nutrient solution are evenly transported by the gas-liquid pump, which can evenly transport the nutrient solution to the microbial culture area, provide the necessary nutritional support for the microorganisms, and further promote their growth and reproduction. This automated liquid delivery system not only improves the efficiency of sewage treatment, but also reduces the need for manual intervention, making the entire treatment process more convenient and efficient.

[0032] like Figure 1 , Figure 2 As shown, the gas-liquid delivery pipe 303 is connected to the outside world through the inflation pump 309, which is used to provide the oxygen and carbon dioxide required by the microorganisms. It can continuously provide the required oxygen and carbon dioxide to the microorganisms, which ensures that the microorganisms have sufficient oxygen supply when performing aerobic respiration, thereby maintaining their normal physiological activities and reproductive capacity. Sufficient oxygen and carbon dioxide are key factors for the metabolism and growth of microorganisms. At the same time, it also helps to improve the degradation efficiency of organic pollutants by microorganisms, because oxygen is necessary for many aerobic microorganisms to degrade organic matter. By continuously supplying oxygen and carbon dioxide, the decomposition process of organic matter in sewage by microorganisms can be accelerated, thereby improving the overall efficiency of sewage treatment.

[0033] like Figure 1 , Figure 2 As shown, the air pump 309, the temperature control layer 306 and the gas-liquid pump are all electrically connected to the external power supply through the control center, so that the entire system can be automatically controlled. By supplying power through the external power supply, it can be ensured that these key components work stably and continuously, thereby maintaining the stability and consistency of the microbial culture environment. At the same time, the electrical connection allows the system to automatically adjust the gas volume of the air pump, the temperature of the temperature control layer and the working state of the gas-liquid pump according to the real-time monitored data to meet the optimal conditions for microbial growth. This intelligent control method not only improves the accuracy and efficiency of sewage treatment, but also reduces the complexity of manual operation and reduces the error rate, providing a strong guarantee for the optimization and stable operation of the sewage treatment process.

[0034] like Figure 2 , Figure 3As shown, the plant planting plate 305 is a quasi-natural wetland for cultivating algae, and is complementary to the expansion of microorganisms. The plant planting plate 305 is set as a quasi-natural wetland, which introduces a natural ecological treatment link to the sewage treatment system. Algae can produce oxygen through photosynthesis, provide more sufficient dissolved oxygen for microorganisms, and absorb and utilize nutrients in sewage. At the same time, it promotes the symbiotic relationship between microorganisms and algae. Microorganisms can decompose organic pollutants and release nutrients that can be used by algae, while algae provide oxygen to the system through photosynthesis, further promoting the growth and activity of microorganisms. This complementary relationship improves the purification efficiency of the entire sewage treatment system, so that harmful substances in sewage are more effectively removed.

[0035] like Figure 3 As shown, a partition 304 is provided inside the second inner cylinder 302 for dividing the interior of the second inner cylinder 302 into four parts for cultivating different microbial colonies, so that four different microbial colonies can be cultivated at the same time. This separation provides an independent and stable environment, which is conducive to the growth and reproduction of various microorganisms under optimal conditions. At the same time, cultivating different microbial colonies can effectively treat different types of pollutants in sewage. Different microorganisms have different degradation capabilities and preferences for pollutants. Therefore, a diverse microbial community can more comprehensively degrade harmful substances in sewage, thereby improving the efficiency and effectiveness of sewage treatment and enhancing the adaptability and treatment capacity of the entire sewage treatment system.

[0036] Embodiment 2:

[0037] like Figure 1 As shown, a pretreatment grid 2 is arranged above the outer side of the outer ring 1 for filtering solid debris in the sewage. The pretreatment grid 2 is arranged above the outer side of the outer ring 1, and can effectively filter larger debris in the sewage, such as paper scraps, plastic fragments, etc., which helps to protect the normal operation of the subsequent treatment unit and prevent the debris from clogging or damaging the equipment. At the same time, through the filtering effect of the pretreatment grid, a part of the suspended matter in the sewage can be removed, thereby reducing the burden of the subsequent biological treatment unit and improving the treatment efficiency of the sewage by microorganisms. The existence of the pretreatment grid 2 provides a preliminary but important purification step for the entire sewage treatment system, ensuring the smooth progress of the treatment process.

[0038] During implementation, microbial colonies are cultured in the inner cylinder. According to the main factors affecting the growth and expansion of microorganisms: pH value, temperature, dissolved oxygen, nutrient solution concentration, growth factors, light, auxiliary conditions, etc., the inner cylinder is designed with components that can adjust relevant indicators in sequence: acid-base neutralization liquid medicine box 307, temperature control layer 306, air pump 309, nutrient solution medicine box 308, pharmacy, plant planting plate 305 used for plant cultivation and stirring blade 310. A gas-liquid delivery pipe 303 and an automatic control circuit are also laid between the first inner cylinder 301 and the second inner cylinder 302, which are connected to the detection unit of the integrated module. The requirements of various indicators are regulated by the design of the automatic control system. The temperature control layer 306 provides a suitable temperature for the growth and working environment of microorganisms in the inner cylinder and the outer ring 1 of the device; the acid-base neutralization liquid medicine box 307 and the nutrient solution medicine box 308 are attached to the upper side of the outer wall of the inner cylinder, responsible for providing acid-base neutralization liquid and nutrients for the microbial culture solution and controlling its pH Environment; The air pump 309 is responsible for providing oxygen and carbon dioxide to the inner cylinder to ensure that there is enough dissolved oxygen for the microorganisms to expand. The inner cylinder of the device is divided into four areas by the partition 304. Different types of microbial colonies can be cultivated in each area to meet the treatment needs of different pollutants in domestic sewage. At the bottom of the inner cylinder is a plant planting plate 305, which performs natural wetland-like treatment. By cultivating algae and other plants that are beneficial to the expansion of microorganisms, the two can play a symbiotic role. Combined with the stirring effect of the stirring blade 310, the expansion rate of microorganisms is greatly improved. The stirring blade 310 is a multiple-blade setting to provide space for the expansion and attachment of microorganisms. The inner cylinder cover is designed to be fully transparent, and natural light is used to meet the lighting needs of microorganisms. The inner cylinder of the device is detachable for regular cleaning and later maintenance. The device combines traditional sewage treatment with microbial purification, adopts the structural form of "internal expansion" + "external treatment", and improves the effect of efficient sewage purification.

[0039] The advantages of this technical solution in practical applications include but are not limited to the following:

[0040] The device combines traditional sewage treatment with microbial purification. The structural form of combining "internal expansion" and "external treatment" not only utilizes the biological purification effect of microorganisms, but also strengthens the traditional sewage treatment process, thereby achieving efficient and comprehensive sewage purification effects.
