[0002] Sewage treatment technical methods include MBBR, or moving bed biofilm reactor, which is a new type of biofilm sewage treatment technology. Its core lies in the use of suspended fillers with large specific surface area and good hydrophilicity as carriers for the attachment and growth of microorganisms. These carriers can move freely in the reactor and fully contact with the sewage, thereby improving the treatment efficiency.

[0003] In the prior art, since radioactive wastewater contains a variety of radioactive nuclides and harmful chemicals, its treatment is difficult and demanding. Traditional treatment methods have problems such as low treatment efficiency, high cost, and risk of secondary pollution. In addition, the biological filler device requires manual regular replacement of fillers, cleaning and maintenance during use. Replacing fillers requires downtime, resulting in reduced treatment efficiency and production losses. Secondly, the cleaning and maintenance process requires the use of chemical agents and manual labor, which increases operating costs, etc. Therefore, the present application provides an MBBR degradable biological filler device to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an MBBR degradable biological filler device to solve the problem that the existing biological filler device needs to be manually replaced, cleaned and maintained regularly during use, and the replacement of fillers requires shutdown operation, resulting in reduced treatment efficiency.

The intelligent aeration combines a circulation control system and an online monitoring sensor to intelligently adjust the aeration volume and water circulation speed according to the wastewater composition and microbial activity, optimize the dissolved oxygen distribution, enhance the biodegradation activity, and reduce energy consumption.

[0011] The lead shielding layer is arranged outside the container, and the lead shielding layer has a built-in high-efficiency filtering and concentration unit to centrally collect the biofilm detached during the treatment process and the adsorbed radioactive particles.

[0012] The controller includes a display screen and control buttons, which are used to display and manage the operating status and key parameters of the system to ensure the efficiency and stability of the sewage treatment process.

[0013] Compared with the prior art, the utility model has at least the following beneficial effects:

DETAILED DESCRIPTION

[0025] The MBBR biodegradable biofiller device provided by the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0026] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, an embodiment of the utility model provides an MBBR degradable biofiller device, including a plurality of biocarriers 2, which are placed in a container 1, and the biocarriers 2 include: a biofiller body 201, which is made of a radiation-resistant composite biodegradable material, and a multi-level biofilm area 202 is formed inside the biofiller body 201; a microporous channel 203, which is opened in the biofiller body 201 to promote the effective contact area between nutrients and microorganisms; a protrusion 204, which is installed on the biofiller body 201 to increase the contact area between nutrients and microorganisms.

[0027] The multi-level biofilm area 202 is used to increase the growth space of microorganisms, which may help different types of microorganisms grow at different levels and improve the treatment efficiency.

[0028] The microporous channel 203 is used to promote the effective contact area between nutrients and microorganisms, increase the opportunity for microorganisms to obtain nutrients, and improve their activity and degradation ability.

[0029] The protrusions 204 are used to increase the contact area between nutrients and microorganisms, which helps to improve the material exchange efficiency and enhance the processing capacity of the biological carrier 2.

[0030] like Figure 6 As shown, each level of the multi-level biofilm area 202 uses microbial flora with different characteristics to form a stepped degradation system. The upper level is mainly responsible for the initial adsorption and transformation of radioactive substances, while the lower level deeply degrades difficult-to-decompose organic matter and transforms radioactive isotopes, thereby achieving efficient graded treatment.

[0031] By placing microbial communities with different characteristics at different levels, layered treatment of pollutants is achieved. The upper layer is responsible for the initial adsorption and transformation of radioactive substances, allowing radiation-resistant microorganisms to quickly come into contact with radioactive substances and begin their degradation or transformation process. The lower layer is used to treat more complex or more stubborn pollutants, ensuring that these substances are effectively degraded or transformed, reducing environmental pollution and helping to improve treatment efficiency. Microorganisms at each level can focus on the treatment process they are best at, avoiding the inefficiency that may be caused by a single bacterial community treating all types of pollutants.

[0032] like Figure 2 , Figure 4 and Figure 5 As shown, the grille 3 is installed in the container 1 and at one end close to the water inlet; the cleaning part 4 is installed in the container 1, and the cleaning part 4 includes: a bidirectional screw 401; and a water wheel 402 installed on the bidirectional screw 401.

[0033] The screen 3 is used to remove large particles of debris in the sewage to prevent these substances from entering the subsequent treatment equipment and causing blockage or damage, thereby reducing the pressure in the subsequent treatment steps and improving the treatment efficiency.

[0034] like Figure 4 and Figure 5 As shown, the connecting member 403 is movably mounted on the bidirectional screw 401 ; the cleaning brush 404 is mounted on the connecting member 403 , and the cleaning brush 404 is in contact with the grille 3 .

[0035] The cleaning part 4 also includes: a cleaning brush 404 in contact with the grille 3, and under the drive of the bidirectional screw 401, the power transmitted through the connecting piece 403 is used to clean the grille 3 to remove impurities attached thereto, prevent blockage and accumulation, and maintain the permeability of the grille 3 through regular or continuous cleaning to ensure the effect of sewage pretreatment, so that large solids can be effectively intercepted.

[0036] like Figure 2 , Figure 3and Figure 4 As shown, the intelligent aerator 5 is installed on the container 1. The intelligent aerator 5 combines the circulation control system and the online monitoring sensor to intelligently adjust the aeration volume and the water circulation speed according to the wastewater composition and microbial activity, optimize the dissolved oxygen distribution, enhance the biodegradation activity, and reduce energy consumption.

[0037] The role of the intelligent aeration 5 and circulation control system 6 in sewage treatment is to optimize the treatment process, enhance the degradation activity of microorganisms, and reduce energy consumption. Through the data collected by the online monitoring sensor, the intelligent aeration 5 can monitor the composition of the wastewater and the activity of the microorganisms in real time, which enables the system to intelligently adjust the aeration volume and the water circulation speed according to the actual situation to ensure that the treatment process is always carried out in the best state. The intelligent aeration 5 helps to create an environment more suitable for microbial growth and pollutant degradation by accurately controlling the air supply and optimizing the dissolved oxygen distribution in the biochemical pool, thereby improving the efficiency of biological treatment. The appropriate aeration volume can not only provide enough oxygen for microorganisms to decompose organic matter, but also prevent sludge precipitation through the circulation of water flow, maintain good contact reaction conditions for microorganisms, and the intelligent control system can avoid excessive aeration and energy waste, reduce unnecessary energy consumption, and meet environmental protection requirements.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the lead shielding layer 7 is arranged outside the container 1, and the lead shielding layer 7 has a built-in high-efficiency filtering and concentration unit to centrally collect the biofilm detached during the treatment process and the adsorbed radioactive particles.

[0039] The role of the lead shielding layer 7 in the sewage treatment system is mainly to provide protection and centralized collection of radioactive substances generated during the treatment process. Since lead has a good ability to shield rays, the lead shielding layer 7 can effectively block the radioactive radiation that may be generated during the treatment process, protect the external environment and workers from radiation contamination, and the built-in high-efficiency filtration and concentration unit of the lead shielding layer 7 can effectively capture and centrally collect the biofilm detached during the treatment process and the adsorbed radioactive particles. This not only reduces the spread of radioactive pollutants, but also facilitates the subsequent treatment and disposal of these harmful substances. By centrally collecting the detached biofilm and radioactive particles, the lead shielding layer 7 helps to maintain the biological treatment efficiency in the biochemical pool and prevents these substances from having a negative impact on the activity of microorganisms. The setting of the lead shielding layer 7 helps to prevent radioactive substances from leaking into the external environment, thereby protecting the surrounding ecosystem and human health.

[0040] like Figure 2 As shown, the controller 6 includes a display screen and control buttons, which are used to display and manage the operating status and key parameters of the system to ensure the efficiency and stability of the sewage treatment process.

[0041] Controller 6 ensures the efficiency and stability of the treatment process. Through the connected sensors and instruments, the controller can collect data on key parameters such as water quality, flow, temperature, etc. in real time so that the operator can understand the operating status of the system in a timely manner. Controller 6 can also automatically adjust the operation of the equipment according to the preset procedures and conditions, such as pump speed, gas volume, etc., to optimize the treatment efficiency and effluent quality. Controller 6 can realize the automatic control of the sewage treatment process, reduce manual intervention, improve work efficiency, and to a certain extent realize intelligent troubleshooting to ensure the continuous and stable operation of the system.

[0042] The technical solution provided by the utility model is that when in use, radioactive sewage passes through the grille 3 to filter some impurities in the sewage, and then flows into the reaction area, where the microorganisms are immobilized by the biological carrier 2. At the same time, the cleaning part 4 can clean the impurities on the surface of the grille 3 to avoid blockage that affects work efficiency.

[0043] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
