Description

Technical Field

[0001] This utility model relates to the field of river management, and in particular to a membrane aeration biological purification system. Background Technology

[0002] The membrane aeration biological purification system is a treatment device that combines membrane separation technology and biological treatment technology. In recent years, it has been widely used in river water management, domestic sewage treatment, industrial wastewater treatment, and rural sewage treatment. Its working principle mainly involves controlling the flow and distribution of oxygen through a membrane bioreactor to optimize biofilm formation and biological reaction processes. This coupled system can effectively improve the utilization rate of oxygen in wastewater, enhance the biological activity of sludge, thereby improving pollutant removal efficiency and system operational stability.

[0003] Existing membrane bioreactors (MBRs) are fixed to a frame, and their aeration density varies depending on the application. For example, when used in rivers, where the rivers are long, adjusting the installation density of the MBRs is crucial for achieving a balance between treatment efficiency and cost-effectiveness, thus limiting their applicability. However, existing MBRs cannot adjust their installation density to meet diverse needs, resulting in limited versatility. Utility Model Content

[0004] The purpose of this invention is to provide a membrane aeration biological purification system that achieves better versatility and practicality by adjusting the density between membrane bioreactors.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a membrane aeration biological purification system, including an installation frame and a plurality of membrane bioreactors. The installation frame has an elongated installation area for installing the membrane bioreactors. The plurality of membrane bioreactors are arranged along the length of the installation area. Each membrane bioreactor is provided with a positioning component between itself and the installation area, which allows the membrane bioreactor to reciprocate along the length of the installation area and achieves damping fixation between the membrane bioreactor and the installation area. The installation area is provided with a plurality of transverse support rods. Each transverse support rod is slidably arranged in the installation area along the length of the installation area, and each transverse support rod is provided with a detachable fixing component between itself and the installation area.

[0006] By employing the above technical solution, the transverse support rod and the membrane bioreactor are adjusted and fixedly installed within the installation area using positioning and fixing components. When it is necessary to change the installation distance between the membrane bioreactors, the membrane bioreactors are pushed along the length of the installation area. When the pushing force exceeds the frictional resistance, the position of the membrane bioreactors can be adjusted. After adjustment, the damping provided by the positioning components secures the membrane bioreactors within the installation area. Once the position of the membrane bioreactors is adjusted, the position of the transverse support rods must also be adjusted accordingly to ensure a stable installation space for the membrane bioreactors.

[0007] The mounting frame is further configured to include two connectors extending along the length of the mounting area and constituting the mounting area, wherein the mounting area is formed between the two connectors and the connectors are made of deformable material.

[0008] By adopting the above technical solution, the connectors are made of deformable materials to facilitate their transportation and installation, thereby reducing transportation costs and making on-site installation easier.

[0009] The positioning component is further configured such that: the positioning component includes an elastic claw disposed on the membrane bioreactor and an elastic locking hole formed on the elastic claw and having an opening; when the connector is engaged with the elastic locking hole, the elastic locking hole clamps the connector.

[0010] By adopting the above technical solution, the connector is inserted into the elastic locking hole, and the membrane bioreactor is fixed on the connector by clamping the connector with the elastic claws; when the thrust applied to push the membrane bioreactor is greater than the clamping force of the elastic claws, the membrane bioreactor can be moved and repositioned, and this structure can also facilitate the installation of the membrane bioreactor.

[0011] The fixing assembly is further configured such that: the fixing component includes a fixing hole formed in the transverse strut and through which the connector passes, and a fixing bolt threaded to the transverse strut and abutting the connector at the position located in the fixing hole.

[0012] By adopting the above technical solution, the connector passes through the fixing hole, and the horizontal strut is movably fixed to the connector by the fixing bolt, thus ensuring the support stability of the horizontal strut.

[0013] The method is further configured such that each of the transverse support rods has a planting groove that extends vertically through the transverse support rod, and the planting groove extends along the length of the transverse support rod in a long strip shape.

[0014] By adopting the above technical solutions, aquatic plants can be planted on the horizontal support rods in the planting troughs. The plants are used to treat the water body and form a healthy ecosystem. This achieves a virtuous cycle of self-maintenance and self-succession of the ecosystem, and achieves the goal of long-term and effective treatment.

[0015] The planting trough is further configured such that: an elastic fastener is provided inside the planting trough, and a limiting plate is provided at the bottom of the planting trough to restrict the fastener from falling, and the limiting plate does not completely close the lower opening of the planting trough.

[0016] By adopting the above technical solution, the fasteners are set to press against both the plant and the planting trough, thereby ensuring the stable planting of the plant in the planting trough.

[0017] The mounting frame is further configured to include two frames, which are foldable structures, and the connectors are connected to the two frames.

[0018] By adopting the above technical solution, the foldable frame is easy to transport, thereby reducing transportation costs.

[0019] A further feature is provided: each of the aforementioned frames is equipped with a counterweight frame.

[0020] By adopting the above technical solution, weight is added to the counterweight frame to achieve a stable installation of the installation frame in the river channel.

[0021] In summary, this invention has the following beneficial effects: by achieving density adjustment between membrane bioreactors, it makes them more versatile and practical; and by using plants to treat water bodies, it creates a healthy ecosystem. Attached Figure Description
