Description

Technical Field

[0001] This utility model relates to the field of wastewater purification technology, specifically to an aerobic fermentation purification reactor for fecal wastewater. Background Technology

[0002] Aerobic fermentation purification of fecal wastewater is a treatment technology that decomposes organic matter in sludge into stable and harmless substances. The aerobic fermentation purification reactor for fecal wastewater is a highly efficient and convenient fecal wastewater treatment equipment. Its main purpose is to create a reproductive reaction environment for microorganisms, and then, through the action of microorganisms, treat fecal wastewater to make it harmless and utilize it as a resource, thereby reducing environmental pollution.

[0003] Currently, there is a common problem of difficulty in laying sewage pipes in relatively concentrated towns, rural areas, farms, natural scenic areas, tourist attractions, and old residential areas with incomplete supporting facilities. On the other hand, the construction scale and number of large-scale integrated residential communities located in suburban areas are also growing rapidly, leading to a continuous increase in the scale and number of septic tanks. However, there is a lack of proper planning and effective treatment, especially the lack of timely and effective treatment of fecal sewage in septic tanks, which can easily cause pollution to the surrounding environment. Therefore, this application proposes another technical solution to address this problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an aerobic fermentation purification reactor for fecal wastewater. It offers advantages such as effective filtration and purification, as well as enhanced environmental protection. This addresses the problem of rapidly increasing construction scale and number of large-scale residential communities in suburban areas, leading to a continuous increase in the size and number of septic tanks. However, these septic tanks often lack proper planning and effective treatment, particularly regarding the timely and effective treatment of fecal wastewater, which easily pollutes the surrounding environment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an aerobic fermentation purification reactor for fecal wastewater, comprising a fixed frame, wherein a filtration and purification mechanism is provided on the top of the fixed frame;

[0006] The filtration and purification mechanism includes an air diffusion unit fixedly installed on the top of the fixed frame, a microbial carrier on the top of the air diffusion unit, a protective net on the top of the microbial carrier, and an air guide pipe body connected to the air diffusion unit on the inner side of the protective net.

[0007] An electromagnetic valve group control system is fixedly installed on the top of the microbial carrier, and an air guide pipe connector is fixedly installed on the top of the electromagnetic valve group control system. An air pump body is fixedly connected to the right side of the air guide pipe connector, and an air pump protection box is provided on the outside of the air pump body.

[0008] Furthermore, the fixing frame serves to support and fix other components in the fecal sewage air diffusion tank or septic tank, ensuring the stability and safety of the entire system.

[0009] Furthermore, the air diffusion unit is one of the core components of the fermentation reactor. It is responsible for introducing air or oxygen into the reactor. The incoming air diffuses into tiny bubbles, providing the necessary oxygen for microorganisms and promoting the decomposition of organic matter.

[0010] Furthermore, the microbial carrier provides an implantation medium for microbial reproduction, allowing microorganisms to reproduce better without reducing their number due to liquid discharge.

[0011] Furthermore, the protective netting is used to prevent debris from entering the reactor and to protect the air diffuser and other sensitive components from damage.

[0012] Furthermore, the solenoid valve assembly control system is used to regulate and control the gas flow rate during the air diffusion process, ensuring that microorganisms react under suitable conditions.

[0013] Furthermore, the main body of the air duct is a pipe for transporting air, and the air duct connector can connect the main body of the air duct and the air diffusion unit.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This aerobic fermentation purification reactor for fecal wastewater, through optimized selection and cultivation of microbial strains, can rapidly and effectively degrade organic matter such as proteins, carbohydrates, and fats in fecal wastewater. Through the biodegradation process, the reactor can significantly reduce harmful substances in fecal wastewater, such as ammonia nitrogen, nitrite, and phosphate, thereby mitigating environmental pollution. During biodegradation, the reactor can recover nutrients such as nitrogen and phosphorus from the fecal wastewater, which can be used as agricultural fertilizers, achieving resource recycling and reducing dependence on chemical fertilizers. The biodegradation process significantly reduces the organic matter and nitrogen content in fecal wastewater, thus improving water quality. Furthermore, through the action of microorganisms, odorous substances in fecal wastewater are reduced, improving the environmental quality around the treatment facility. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 The fecal sewage aerobic fermentation purification reactor in this embodiment includes a fixed frame 01, and a filtration and purification mechanism is provided on the top of the fixed frame 01.

[0023] In this embodiment, the filtration and evolution mechanism includes an air diffusion unit 02 fixedly installed on the top of the fixed frame 01. The fixed frame 01 plays a role in supporting and fixing other components in the fecal sewage air diffusion tank or septic tank, ensuring the stability and safety of the entire system. The air diffusion unit 02 is one of the core components of the fermentation reactor. It is responsible for introducing air or oxygen into the reactor. The air that is delivered diffuses into tiny bubbles, providing the necessary oxygen for microorganisms and promoting the decomposition of organic matter.

[0024] The air diffusion unit 02 is equipped with a microbial carrier 03 at its top. The microbial carrier 03 provides a substrate for microbial reproduction, allowing microorganisms to reproduce better and preventing the number of microorganisms from decreasing due to liquid discharge. The microbial carrier 03 is equipped with a protective net 04 at its top. The protective net 04 is used to prevent debris from entering the reactor and to protect the air diffusion pipe and other sensitive components from damage. The inner side of the protective net 04 is equipped with a guide pipe body 05 that is connected to the air diffusion unit 02.

[0025] In this embodiment, a solenoid valve group control system 06 is fixedly installed on the top of the microbial carrier 03. The solenoid valve group control system 06 is used to regulate and control the gas flow rate during the air diffusion process to ensure that the microorganisms react under suitable conditions. A gas guide pipe connector 07 is fixedly installed on the top of the solenoid valve group control system 06. The gas guide pipe body 05 is a pipe for transporting air. The gas guide pipe connector 07 can connect the gas guide pipe body 05 and the air diffusion unit 02. An air pump body 09 is fixedly connected to the right side of the gas guide pipe connector 07. An air pump protection box 08 is provided on the outside of the air pump body 09.

[0026] The working principle of the above embodiments is as follows:

[0027] This aerobic fermentation and purification reactor for fecal wastewater features a 45cm diameter standing microbial attachment carrier system that can be directly installed in most septic tank systems. Users do not need to modify their existing septic tank structure; only a 2.5cm diameter hole needs to be drilled in the top of the septic tank to install the main air duct (05). The pump should be installed in a cool, shaded area, avoiding direct sunlight and low-lying locations to prevent water accumulation and damage. The reactor utilizes a fixed-film microbial community and an aerobic biodegradation process. Microbial metabolic activities help complete the nutrient cycle within the septic tank, increasing the total metabolic output and significantly reducing pollutant concentrations in the effluent. This process renders the fecal wastewater harmless and converts organic matter into organic fertilizer. In the reactor, microorganisms use oxygen for aerobic respiration, decomposing organic matter into energy and carbon dioxide. Simultaneously, microorganisms convert nutrients such as nitrogen and phosphorus in the reactor into forms usable by plants, achieving resource recycling.
