Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to a membrane bioreactor for wastewater treatment. Background Technology

[0002] Membrane bioreactors (MBRs) are highly efficient wastewater treatment devices that combine membrane separation technology with biotechnology, and are widely used in the treatment of industrial and domestic wastewater. However, existing MBRs suffer from insufficient installation and positioning accuracy of the membrane modules, leading to swaying or displacement and affecting filtration efficiency. Furthermore, the flow rate of the membrane modules is difficult to monitor in real time, often requiring maintenance only after severe clogging occurs, resulting in decreased wastewater treatment effectiveness. In addition, the installation and removal of membrane modules is cumbersome, requiring additional tools and increasing maintenance costs and time. Therefore, to address these issues, this application provides a membrane bioreactor for wastewater treatment. Utility Model Content

[0003] To address the aforementioned problems, this application provides a membrane bioreactor for wastewater treatment.

[0004] This application provides a membrane bioreactor for wastewater treatment, characterized in that it includes a frame, with guide blocks and support seats for placing membrane modules on the inner side of the frame; a pipe connected to the outside is provided at the top of the membrane module, and a flow meter is provided on the pipe; a bracket is provided above the frame, and a lifting rope is fixed on the membrane module; a slot is provided on the bracket, and the lifting rope is placed in the slot when not in use.

[0005] Preferably, the membrane assembly is positioned and placed inside the frame via the guide block and support seat.

[0006] Preferably, the flow meter is used to monitor the flow rate of the pipeline per unit time to determine the throughput efficiency of the membrane module.

[0007] Preferably, when the membrane module has a low throughput, it can be reverse-cleaned or removed and replaced as a whole.

[0008] Preferably, the lifting rope is removed from the bayonet during use to lift the membrane assembly upwards, improving ease of loading and unloading.

[0009] Preferably, the bracket is disposed above the frame, providing a placement structure for the lifting rope when idle and a lifting assistance structure when in use.

[0010] Preferably, the pipeline connects the membrane module to an external treatment system to realize the transmission of wastewater and the discharge of treated water.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] By setting guide blocks and support seats inside the frame, the membrane module is accurately positioned and stably placed. The flow meter on the pipeline can monitor the flow efficiency of the membrane module in real time, which facilitates timely reverse cleaning or overall replacement, ensuring the sewage treatment effect. The bracket above the frame works in conjunction with the lifting rope on the membrane module. The lifting rope is stored in an orderly manner through the locking mechanism, and the membrane module can be lifted easily, which greatly improves the convenience of loading, unloading and maintenance. The overall structure is reasonably designed and highly practical, which can effectively improve sewage treatment efficiency and equipment maintenance convenience. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0019] Example 1:

[0020] A membrane bioreactor for wastewater treatment, reference Figure 1 - Figure 4 It is mainly composed of components such as frame 1, membrane module 2, pipe 3, flow meter 4, lifting rope 5, bracket 6, guide block 7 and support base 8. The components work together to achieve efficient sewage treatment and convenient maintenance.

[0021] Frame 1, serving as the fundamental support structure of the entire reactor, is made of high-strength, corrosion-resistant material. It can be designed as a rectangular or square structure depending on the actual treatment scale, with its size adaptable to the flow rate of the wastewater to be treated and the number of membrane modules 2 installed. Multiple guide blocks 7 are vertically spaced along the inner wall of frame 1. Each guide block 7 is elongated with a right-angled trapezoidal cross-section, its inclined surface facing the installation direction of the membrane modules 2, facilitating precise guidance during installation. Simultaneously, at the bottom inner side of frame 1, a support base 8 is provided corresponding to the installation position of each membrane module 2. The top of the support base 8 has a groove that matches the bottom of the membrane module 2, and an elastic buffer pad is embedded within the groove. This provides stable support for the membrane module 2 and prevents damage caused by rigid contact between the membrane module 2 and the support base 8.

[0022] Membrane modules 2 are the core components of wastewater treatment, made of high-efficiency filtration materials such as hollow fiber membranes or flat sheet membranes. Their number can be configured according to treatment needs, and they are typically arranged in an array within frame 1. Each membrane module 2 has a pipe 3 connected to its top via a flange. Pipes 3 are made of corrosion-resistant PVC or stainless steel. The pipes 3 of each membrane module 2 ultimately connect to the main pipe, enabling communication with the external treatment system. This allows wastewater to be introduced into the membrane module 2 for filtration and the treated water to be discharged to subsequent treatment units. A flow meter 4 is installed in series on each pipe 3. The flow meter 4 is a high-precision electromagnetic flow meter or turbine flow meter, with a measurement range adapted to the design flow rate of the membrane module 2. It is connected to the external control system via wires, allowing real-time transmission of the monitored flow rate data per unit time to the control system.

[0023] The control system calculates the throughput efficiency of membrane module 2 based on the flow data fed back from flow meter 4. When the throughput efficiency is lower than a preset threshold, the system will automatically issue a warning signal. At this time, the operator can choose two maintenance methods: for mild clogging, the backwash valve on pipe 3 can be opened to allow the cleaning fluid to flow through membrane module 2 in the opposite direction to normal filtration, thus achieving reverse cleaning of membrane module 2; for severely clogged or aged membrane module 2, it needs to be removed and replaced as a whole to ensure the reactor's treatment efficiency.

[0024] To facilitate the installation and removal of membrane modules 2, a bracket 6 is fixedly installed above the frame 1. The bracket 6 is made of aluminum alloy and has a portal-like structure spanning above the frame 1. Each membrane module 2 has a corresponding slot 61 on the crossbeam of the bracket 6. The slot 61 is U-shaped with its opening facing upwards, and its inner wall is lined with a rubber anti-slip pad. Lifting ropes 5, made of high-strength nylon or steel wire rope, are fixedly connected to both sides of the top of the membrane module 2, and their length is slightly longer than the height of the membrane module 2. When the membrane module 2 is working normally, the lifting rope 5 is wound around and placed in the corresponding slot 61, and the rubber anti-slip pad prevents the lifting rope 5 from slipping out of the slot 61. When maintenance or replacement of the membrane module 2 is required, the operator only needs to remove the lifting rope 5 from the slot 61, lift the membrane module 2 upwards using the lifting rope 5, and release the membrane module 2 from the constraints of the guide block 7 and the support seat 8, making it easy to remove from the frame 1. This significantly reduces the difficulty of operation and improves maintenance efficiency.

[0025] This invention ensures the stability and accuracy of membrane module 2 installation by rationally setting the guide block 7 and support base 8; it realizes real-time monitoring of the flow efficiency of membrane module 2 by using the flow meter 4 on the pipeline 3, which facilitates timely cleaning or replacement measures; and it significantly improves the convenience of membrane module 2 loading and unloading by cooperating with the bracket 6, the bayonet 61 and the lifting rope 5. The overall structure is reasonable, easy to operate and maintain, and can operate stably for a long time. It is suitable for various industrial wastewater and domestic sewage treatment scenarios.
