[0002] In the field of wastewater treatment, traditional activated sludge processes suffer from issues such as large footprint, high energy consumption, and high sludge production. To overcome these issues, biological aerated filter technology has gained widespread attention and application in recent years. Biological aerated filters utilize fixed biofilms to treat wastewater, offering advantages such as high treatment efficiency, a small footprint, and strong resistance to shock loads.

[0003] However, existing biological aerated filters still face several practical challenges. First, the filter media is prone to clogging, which not only affects the normal operation of the system but also increases the difficulty and cost of maintenance. Second, operating costs are relatively high, primarily due to energy consumption and costs such as filter media replacement. Furthermore, aeration systems are often not uniform and efficient in actual operation, resulting in uneven oxygen distribution, which affects microbial activity and pollutant degradation efficiency. These issues ultimately lead to unstable treatment results, making it difficult to meet stringent environmental protection requirements.

DETAILED DESCRIPTION

[0018] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0019] like Figure 1 、 Figure 2 and Figure 3 As shown, the present invention provides a technical solution for an aerated biological filter: it includes an aeration tank 1, in which an aeration assembly is installed. The aeration assembly includes an aeration main pipe 21, and multiple aeration pipes 22 are connected to the aeration main pipe 21. An aeration seat 23 is installed at the bottom of each aeration pipe 22. The aeration seat 23 is arranged in a cube shape, and a pipe interface 24 is provided at the top for assembling and connecting the aeration pipes 22. Each outer wall of the aeration seat 23 is provided with a plurality of aeration recesses 25, and an aeration head 26 for gas discharge is installed in each aeration recess 25, and the aeration head 26 is connected to the aeration pipe 22.

[0020] A support frame 11 is installed on the outside of the aeration tank 1 to ensure its stability and durability. A drain pipe 12 is installed at the bottom of the aeration tank 1 to drain the wastewater when necessary. A control valve 13 is installed on the drain pipe 12 to facilitate the control of the discharge process.

[0021] The aeration main pipe 21 is used to connect to an air compressor, which is connected to the aeration main pipe 21 through a pipeline to provide a stable air source. This ensures that the aerated biological filter has sufficient air supply during operation, thereby improving the efficiency of sewage treatment.

[0022] Aeration tank 1 is equipped with a filtration assembly comprising two sets of filter frames 31. These two sets of filter frames 31 are arranged in an inclined configuration. One set of filter frames 31 is equipped with a grille 32 to intercept larger suspended solids and prevent them from entering subsequent treatment. The other set of filter frames 31 is equipped with a biofilter membrane 33, which is attached with microorganisms that effectively degrade organic matter in the wastewater.

[0023] The aeration pipe 22 and the pipe interface 24 are sealed to prevent gas leakage. This sealing process ensures airtightness during the aeration process, thereby improving oxygen utilization, further enhancing microbial activity and pollutant degradation efficiency.

[0024] In this embodiment, sewage first enters the aeration tank 1 through the water inlet. Under the action of the aeration assembly, an air compressor delivers air into the aeration main pipe 21, which is then evenly distributed to each aeration seat 23 through aeration pipes 22. Aeration heads 26 release air into the water in the form of tiny bubbles, thereby increasing the dissolved oxygen content in the water, providing sufficient oxygen for microorganisms and promoting their degradation of organic pollutants.

[0025] When wastewater needs to be discharged, control valve 13 opens, and suspended matter in the wastewater is intercepted by grille 32 within filter frame 31, preventing larger particles from entering biofilter membrane 33. Microorganisms on biofilter membrane 33 then biodegrade organic matter in the wastewater, further purifying the water. The inclined design of filter frame 31 facilitates self-cleaning of the filter media, reduces clogging, and ensures filtration efficiency. Discharge pipe 12 discharges the treated water, and frame 11 ensures stable operation of the entire biological aeration filter, preventing structural damage from vibration or external impact.

[0026] Through this design, the aerated biological filter of the utility model not only improves the efficiency of sewage treatment, but also reduces energy consumption and maintenance costs. The optimized design of the aeration component and the filter component makes the entire system more efficient, stable, and easy to operate and maintain.
