Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to an integrated MBR membrane sewage treatment device. Background Technique

[0002] Sewage treatment is a process of treating sewage generated in urban and industrial life through a series of physical, chemical, and biological treatment processes to remove pollutants and make the water quality meet the discharge or recyclable water quality standards. It usually includes stages such as pretreatment, primary treatment, secondary treatment, tertiary treatment, and disinfection. Sewage treatment can not only reduce environmental pollution but also protect water resources and public health.

[0003] MBR is an advanced sewage treatment technology that combines a bioreactor and membrane separation technology. It uses a microporous membrane filter instead of a traditional sedimentation tank to effectively separate the sludge and sewage generated in the bioreactor, thereby improving the treatment efficiency and water quality purification ability. The MBR system can not only completely remove pollutants such as suspended solids, bacteria, and viruses but also adapt to the treatment of high-concentration and complex sewage, making the treated water quality meet the standards for reuse or safe discharge. It is widely used in fields such as urban sewage treatment, industrial wastewater treatment, and water resource recovery.

[0004] The MBR membrane is a filter device that can be recycled. It only needs to clean the impurities attached to the surface. However, due to the large overall volume of the MBR membrane and the need to lift the MBR membrane out of the pool for cleaning, the traditional method is to lift it by manpower or a separate lifting device. This method is not only time-consuming and laborious but also inefficient. Therefore, an integrated MBR membrane sewage treatment device is proposed to solve the above problems.

[0032] Specifically, the sewage tank 1 is a water tank for collecting sewage. The limiting rods 2 are used to limit the moving direction of the sliding frame 3, so that the sliding frame 3 can only move up and down and will not move randomly or shake. The sliding frame 3 is used to drive the fixed frame 10 to lift. The link rod 4 is used to push the sliding frame 3 upward. The link rod 5 is used to drive the link rod 4 to be straightened. The gear 6 is used to drive the link rod 5 to deflect. The electric push rod 7 is used to push the rack 8 to move. The rack 8 and the gear 6 are meshed with each other to drive the gear 6 to rotate. The sliding frame 9 is used to limit the moving direction of the rack 8 to ensure that the rack 8 can only move back and forth and will not move randomly or shake.
