Description

Technical Field

[0001] This invention relates to the field of BBR biological rotating disc technology, and particularly to a BBR biological rotating disc integrated biochemical filter. Background Technology

[0002] In the BBR biological rotating disc integrated biological filter, the design of the rotating disc is crucial, as it directly affects the uniformity of water treatment, oxygen distribution, and system stability. To meet the needs of different water qualities, the rotating disc should adopt a multi-layer structure and a dynamic speed regulation system to achieve efficient water mixing and gas exchange. High-temperature and corrosion-resistant materials should be selected to enhance the durability of the equipment, and a monitoring system should be equipped to reflect the operating status in real time, ensuring that excellent treatment performance can still be maintained under high load conditions. This is a key challenge in the design.

[0003] A typical BBR (Biological Rotating Disc) integrated biofilter consists of three parts: a biological rotating disc unit, a reaction tank, and a drive system. The biological rotating disc unit, as the core functional component of the filter, utilizes a highly active biofilm attached to its surface and a special disc structure design to ensure efficient organic matter degradation and nitrogen and phosphorus removal during wastewater treatment. The reaction tank, as the foundation of the filter, employs a zoned design and optimized water flow channel structure to stably accommodate wastewater and guide it into full contact with the biological rotating discs during operation. The drive system, through precise speed control and reliable power transmission, ensures uniform rotation of the biological rotating discs. This avoids biofilm detachment due to excessive speed and prevents insufficient contact efficiency between wastewater and biofilm due to insufficient speed, ultimately ensuring the reliability and consistent treatment effect of the filter during long-term, continuous operation, meeting the wastewater treatment needs of different scenarios.

[0004] In BBR biofilm systems, insufficient oxygen significantly affects cleaning efficiency because the metabolic activities of microorganisms depend on a sufficient oxygen supply. When the oxygen supply is insufficient, aerobic microorganisms in the biofilm cannot effectively carry out degradation reactions, resulting in a decrease in pollutant removal rate. Insufficient oxygen also leads to the proliferation of anaerobic microorganisms, producing odors and harmful gases, thereby further reducing the overall water treatment effect and water quality. To address these issues, a BBR biological rotating disc integrated biochemical filter is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a BBR biological rotating disc integrated biochemical filter, which aims to improve the problem of insufficient oxygen in the BBR biofilm leading to a decrease in cleaning efficiency in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A BBR biological rotating disc integrated biochemical filter includes a tank body, an air supply unit fixedly connected to the outside of the tank body, an adjustment mechanism fixedly connected to the outside of the air supply unit, and a vibration mechanism installed inside the tank body. The adjusting mechanism includes a fixed shell, which is fixedly connected to the outside of the air supply unit. A hydraulic cylinder is fixedly connected inside the fixed shell. A sliding plate is fixedly connected to the drive end of the hydraulic cylinder. A rotating block one is slidably connected to the outside of the sliding plate. A rotating block two is slidably connected to the outside of the sliding plate. A drive assembly is fixedly connected inside the tank. As a further description of the above technical solution: The drive assembly includes a motor, which is externally fixedly connected to the outside of the pool body. A rotating frame is fixedly connected to the drive end of the motor, and multiple support plates are fixedly connected to the outside of the rotating frame. As a further description of the above technical solution: The vibration mechanism includes multiple culture dishes, the outside of which are slidably connected to the inner wall of the support plate, and a driving device is fixedly connected inside the culture dish. Two centrifuge blocks are fixedly connected to the driving end of the driving device, and two support columns are slidably connected to the inner wall of the culture dish. As a further description of the above technical solution: The rotating block is externally fixedly connected to a rotating shaft, and the rotating shaft is externally rotatably connected to the inner wall of the gas supply unit. As a further description of the above technical solution: A fan blade one is fixedly connected to the outside of the rotating shaft, and a fan blade two is rotatably connected to the outside of the rotating shaft; As a further description of the above technical solution: The second fan blade is externally fixedly connected to the outside of the second rotating block, and the sliding plate is externally slidably connected to the inner wall of the fixed shell. As a further description of the above technical solution: A spring is fixedly connected to the outside of the culture dish, and the spring is fixedly connected to the inner wall of the support plate. A sensor is fixedly connected to one side of the culture dish. As a further description of the above technical solution: Two sludge discharge pipes are fixedly connected to the outside of the pool body, and a water inlet pipe is fixedly connected to the outside of the pool body.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the hydraulic cylinder drives the sliding plate to move, the sliding plate drives rotating block one and rotating block two to rotate, rotating block one drives the rotating shaft to move, the rotating shaft drives fan blade one to rotate, and rotating block two drives fan blade two to rotate. The rotation between fan blade one and fan blade two does not affect the movement. The inner wall of the air supply unit provides support for the rotating shaft, so the air supply effect of the air supply unit can be adjusted, which solves the problem of insufficient oxygen in BBR biofilm leading to a decrease in cleaning efficiency.

[0008] 2. In this utility model, when the driving device on the culture dish is activated, the driving device drives the two centrifuge blocks to rotate. As a result, the culture dish will cause the spring to compress, causing the support column to slide on the inner wall of the culture dish. Therefore, excess biofilm is vibrated and falls into the water and is discharged from the sludge discharge pipe, thus solving the problem of excessive biofilm thickness affecting the treatment effect.
